## Release 1.15.0

### Summary of Changes

This is a major feature release with C++20 as the default standard, comprehensive MongoDB replica set support, a new reactor-based HTTP server implementation, ULID support, C++17 modernization of core classes, and significant third-party library upgrades.

Poco::MongoDB:

- Full replica set support: automatic server discovery, topology monitoring, failover handling, read preference-based server selection, connection pooling, and URI parsing.
- Note: Legacy wire protocol (pre-MongoDB 5.1) has been removed. Use OP_MSG-based interface for all MongoDB operations.

Poco::Net:

- New reactor-based HTTP server implementation (HTTPReactorServer) for high-performance scenarios using the SocketReactor pattern instead of thread-per-connection model.
- HTTP cookies updated to RFC 6265 specification.

Poco::Redis:

- Event notifications support for pub/sub integration.

Poco::Foundation:

- ULID (Universally Unique Lexicographically Sortable Identifier) support with ULIDGenerator class, similar to existing UUID support.
- C++17 modernization of Tuple, TypeList, ScopedLock and other core classes with significant code reduction. Full backward API compatibility maintained.
- New AsyncNotificationCenter for asynchronous notification dispatch with auto-configured worker threads.
- FastLogger (Quill wrapper, fully compatible with Poco Logging system)
- Single/Multiple Producer, Single Consumer lock-free notification queues.
- DataNotification class for carrying typed payloads in notifications.
- NativeThreadInfo support for including native thread ID and name in log messages.
- Thread interrupt feature added for cooperative thread cancellation.
- LogFileImpl::createFile() now creates parent directories if they don't exist.
- Poco::format() now supports %g and %G format specifiers like printf().
- Windows: Missing DLL names now reported in SharedLibrary load errors.
- Poco::Observer is now deprecated; use Poco::NObserver instead.

Poco::NetSSL_Win:

- Find certificates from Windows store using SHA-1 thumbprint for easier certificate selection in enterprise environments.

Poco::Data:

- PostgreSQL: UUID field type (UUIDOID) now correctly mapped to Poco::UUID instead of BLOB, enabling direct UUID value extraction from RecordSet.
- ODBC: Improved Oracle database integer type handling.
- ODBC: Fixed UUID handling in Preparator for SQL Server.

Build System:

- C++20 is now the default standard (use POCO_ENABLE_CPP20 CMake option).
- C++20 modules support added (ENABLE_MODULES). Modules match namespace names (Poco.Foundation, Poco.Net, etc.) with a unified Poco module for importing all.
- External dependencies reorganised into separate 'dependencies' subdirectory.
- New POCO_UNBUNDLED_SQLITE option for fine-grained unbundled control.
- New POCO_MINIMAL_BUILD option builds only the libraries explicitly enabled via ENABLE_* options, useful for reducing build times and binary size.
- CMake uninstall target renamed to 'uninstall-poco' to avoid conflicts.

Bundled Third-Party Library Upgrades:

- expat 2.7.1 → 2.7.4 - fixes CVE-2026-24515 (NULL pointer dereference), CVE-2026-25210 (integer overflow), CVE-2025-59375 (DoS via memory allocation), CVE-2024-8176 (stack overflow)
- PCRE2 10.44 → 10.47 - skips 10.45 which had CVE-2025-58050 (heap-buffer-overflow)
- SQLite 3.49.1 → 3.51.1 - fixes CVE-2025-6965 (memory corruption)
- libpng 1.6.43 → 1.6.53 - fixes CVE-2025-64720, CVE-2025-65018 (buffer overflows), 5 security fixes total
- libharu 2.3.0RC2 → 2.4.5 (first stable release since RC)
- utf8proc 2.9.0 → 2.11.0 - adds Unicode 16 and 17 support
- LZMA SDK 9.22 → 25.01 (major upgrade from 2011 version)
- Quill 11.0.2 (new)

### Breaking Changes and Migration Notes

- GH #5030 Foundation: DateTimeParser rejects trailing garbage. Review any code that relies on specific parsing behavior for non-standard date/time formats.
- GH #4844 AbstractConfiguration::createView() and createLocalView() return AbstractConfiguration::Ptr (AutoPtr) since version 1.11. Code that assigns the return value to a raw pointer (AbstractConfiguration*) will compile but cause use-after-free crashes. Always use AbstractConfiguration::Ptr or auto for the return value.
- GH #4781 Poco::MongoDB legacy wire protocol (OP_INSERT, OP_UPDATE, OP_DELETE, OP_QUERY, OP_GET_MORE) has been removed. These were deprecated in MongoDB 5.0 and removed in MongoDB 5.1. All code must use the OP_MSG-based interface (OpMsgMessage, OpMsgCursor). MongoDB 3.6+ is required.
- GH #4460 Remove VS projects from release. Use CMake to generate Visual Studio solutions.
- GH #3739 Drop support for OpenSSL < 1.1.1. Systems with older OpenSSL versions must upgrade before using this release.

## Release 1.14.0

### Summary of Changes

This release marks many functions and classes as deprecated with C++ attribute. Warnings can be silenced by defining POCO_SILENCE_DEPRECATED.

Deprecated functionality will be removed in one of the next releases.

Minimal supported standard is C++17 since version 1.13. Decent part of the source code is modernised in this release.

Bundled software libraries are updated to latest versions:

- zlib 1.3.1
- expat 2.6.4
- pcre2 10.44
- libpng 1.6.43
- SQLite 3.47.1

Poco::Foundation:

- Support for Version 6 and Version 7 UUIDs

Poco::MongoDB:

- Obsolete wire-protocol (pre 3.6) that was removed from MongoDB in version 5.1 is obsolete in this version of Poco. It will be removed in one of next versions. Update code to use OpMsg-based interface.

Poco::Data:

- Full Nullable support (including bulk inserts)
- ODBC SQL Server big strings support

## Release 1.10.0

### Summary of Changes

- This release now requires a C++14 compiler (GCC 5, Clang 3.4, Visual C++ 2015).

### Incompatible Changes and Possible Transition Issues

- Crypto and NetSSL on Windows: The included Visual Studio project files now expect the OpenSSL headers and libraries to be in the "openssl" directory in the POCO root directory, alongside the Foundation, XML, Net directories. The GitHub repository contains the openssl submodule, which has the required files. The release source packages do not contain these files. They are available from the pocoproject/openssl repository (Zip archive). You can also provide your own build of OpenSSL, by specifying the appropriate header and library search paths in the Visual Studio project files. Through the Poco/Crypto/Crypto.h and Poco/Net/NetSSL.h headers, the libcrypto.lib and libssl.lib libraries will be automatically linked. If you don't want this, build Crypto and NetSSL_OpenSSL with the `POCO_EXTERNAL_OPENSSL` macro defined.

- Poco::XML::NamePool: increased default size from 251 to 509. Default size can now be changed by defining the POCO_XML_NAMEPOOL_DEFAULT_SIZE macro accordingly.
- Enchancements: Poco::XML::Document and Poco::XML::DOMParser have new constructors taking a NamePool size. Poco::Util::XMLConfiguration::load() also has a new overload for that purpose.
- Improved error handling in the Zip library (getting rid of some poco_assert macros and did proper error handling instead).
- Added Poco::URISyntaxException (subclass of Poco::SyntaxException), which is now thrown by Poco::URI.
- Improved error handling in Poco::URIStreamOpener::open().
- Poco::Data::MySQL: Handle connection lost/server gone error when starting a transaction and retry.

### Incompatible Changes and Possible Transition Issues

- Data::ODBC: UTF-16 Unicode is now directly mapped and recognized as type by ODBC. This may cause behavior different from previosu versions, especially with Any and Dynamic::Var bindings. In this release, UTF-16 binding is only available for ODBC back end; although other back ends will compile with UTF-16 strings bound, such binding attempt will throw NotImplementedException at runtime.
- Please note that 1.5.x releases are development releases and not considered stable. Interfaces may change, and backwards compatibility with the stable 1.4 release series is not guaranteed. There may also be some rough edges. The next stable release incorporating 1.5 features will be 1.6.

### Incompatible Changes and Possible Transition Issues

- Dynamic::Var: comparison of two empty objects now returns true
- WinCE does not build in this release; this will be fixed in a later release
- JSON::DefaultHandler was renamed to a more appropriate name - ParseHandler; ParseHandler does not have to be passed to the Parser, it will be used by default; handlers are now passed into Parser as smart pointers, so passing in addresses of stack objects will cause undefined behavior
- Please note that 1.5.x releases are development releases and not considered stable. Interfaces may change, and backwards compatibility with the stable 1.4 release series is not guaranteed. There may also be some rough edges. The next stable release incorporating 1.5 features will be 1.6.

## Release 1.4.2p1

### Summary of Changes

- On Linux, the RTLD_DEEPBIND option is no longer passed to dlopen(). This change was introduced in 1.4.2 to solve a specific problem one customer was having. Unfortunately, it leads to problems with RTTI.
- It's now possible to pass flags (SHLIB_GLOBAL, SHLIB_LOCAL) to Poco::SharedLibrary::load() (and the constructor implicitly calling load()), controlling the mode flags (RTLD_GLOBAL, RTLD_LOCAL) passed to dlopen(). On platforms not using dlopen(), these flags are ignored.
- fixed SF# 3400267: Path_WIN32.cpp bug

## Release 1.4.2

### Summary of Changes

- added Poco::DateTimeFormat::ISO8601_FRAC_FORMAT
- added new Poco::DateTimeFormatter and Poco::DateTimeParser format specifier: %s for seconds with optional fractions of a second
- fixed a problem with ioctl() on BSD platforms (including OS X) where the second argument to ioctl() is unsigned long instead of int, causing bad things on a OS X 64-bit kernel.
- fixed a potential endless loop when enumerating IPv6 network addresses (reported by Laurent Carcagno)
- new compile-time config option on Windows to set thread names in debugger. Enable with -DPOCO_WIN32_DEBUGGER_THREAD_NAMES. Available only in debug builds.
- Cipher can now create Base64 and HexBinary encoded output without linefeeds (suitable for use in cookies, etc.)
- added Poco::Path::popFrontDirectory()
- improved VxWorks support
- IPv6 fixes: added proper scope id handling in IPAddress, SocketAddress and related classes.
- Added Poco::Net::ServerSocket::bind6() which allows control over the IPPROTO_IPV6/IPV6_V6ONLY socket option.
- Removed Poco::MD2Engine class due to licensing issues (the license for the MD2 code from RSA only allows non-commercial use). Note that the MD4 and MD5 code from RSA does not have this issue.
- fixed a Net HTTP client testsuite issue where some tests might have failed due to prematurely aborted connections by the HTTPTestServer.
- Poco::Net::SocketAddress: when there is more than one address returned by a DNS lookup for a name, IPv4 addresses will be preferred to IPv6 ones.
- Poco::Net::NetworkInterface::list() now also returns IPv4 interfaces on Windows when built with -DPOCO_HAVE_IPv6
- Poco::XML::XMLWriter: fixed a bug with attribute namespaces (no namespace prefix written if attribute namespace is the same as element namespace)
- fixed SF# 3378588: Mismatched new[]/delete (in RSAEncryptImpl and RSADecryptImpl)
- fixed SF# 3212954 (OpenSSLInitializer::uninitialize() crash) and SF# 3196862 (Static OpenSSLInitializer instance causes Windows deadlocks) by removing the static Poco::Crypto::OpenSSLInitializer instance. Automatic OpenSSL initialization is now done through Poco::Crypto::Cipher, Poco::Crypto::CipherKey, Poco::Crypto::X509Certificate, Poco::Net::Context classes; however, it is still recommended to call Poco::Crypto::initializeCrypto() and Poco::Crypto::uninitializeCrypto() early at application startup, and late at shutdown respectively (or Poco::Net::initializeSSL()/Poco::Net::uninitializeSSL() if the NetSSL library is used) to avoid multiple full OpenSSL init/uninit cycles during application runtime.
- Poco::Logger now also support a symbolic log level "none" (for use with setLevel()) that disables logging completely for that Logger (equivalent to setLevel(0)).
- Added experimental Android support, using the existing gmake-based build system.
- fixed SF# 3288584: DateTimeFormatter link error
- fixed SF# 3187117: Typo in InflatingInputStream doc
- fixed SF# 3309731: _WIN32_WCE comparison should be with 0x600 not 600
- fixed SF# 3393026: RegularExpression.h identical enum value
- fixed SF# 3274222: AtomicCounter's postfix operators aren't atomic on Windows
- fixed SF# 3317177: Handle leak on windows
- fixed SF# 3181882: Poco::URI::getPathEtc() double-encodes query
- fixed SF# 3379935: Poco::ThreadPool Start Bug
- fixed SF# 3354451: Poco::Format::parsePrec() never sets the precision to zero
- fixed SF# 3387258: _MAX_PATH used but unknown in Path_WIN32
- fixed a problem in Poco::Crypto::RSAKeyImpl where direct access to the RSA in a EVP_PKEY would no longer work in recent OpenSSL versions. Using EVP_PKEY_get1_RSA() fixes the issue.
- added Poco::Crypto::EncryptingInputStream, Poco::Crypto::EncryptingOutputStream, Poco::Crypto::DecryptingInputStream and Poco::Crypto::DecryptingOutputStream.
- fixed SF# 3148126: Poco::Net::HTTPSClientSession destructor throws an IOException
- fixed SF# 3178098: Add constructor to Poco::TemporaryFile to specify directory
- fixed SF# 3175310: Absolute path when device
- fixed SF# 3301207: Guided tour example contradicts apidoc (API doc was wrong)
- Poco::Net::HTTPMessage::setContentLength() and Poco::Net::HTTPMessage::getContentLength() now use std::streamsize instead of int. This enables 64-bit Content-Length support at least on 64-bit platforms.
- fixed SF# 3177530: Poco::TemporaryFile::tempName() + glob bug on xp
- fixed SF# 3177372: Poco::FileChannel documentation inconsistency
- added %E format specifier to Poco::PattermFormatter (epoch time in seconds since midnight, January 1 1970)
- On Windows, Poco::Util::ServerApplication now supports a /description command line argument for specifying a service description (together with /registerService)
- added Poco::Util::WinService::setDescription() and Poco::Util::WinService::getDescription()
- fixed SF# 3155477: Incorrect URI path handling
- fixed SF# 3309736: Extended Exception macros to set default exception code new macro is named POCO_DECLARE_EXCEPTION_CODE
- added getter functions for modulus and exponents to Poco::Crypto::RSAKey.
- added Poco::Net::SocketAddress::operator == () and Poco::Net::SocketAddress::operator != ()
- fixed SF# 3182746: IPAddress.cpp IPv6 bug on big-endian
- fixed SF# 3196961: Unix daemon fails to loadConfiguration() if started from cwd
- fixed SF# 3393700: NotificationCenter may call a removed observer and crash.
- Reworked implementation of the events framework (Poco::BasicEvent and friends). The framework is now completely multithreading save (even in the case that an event subscriber object unsubscribes and is deleted while an event is being dispatched). Also, the restriction that any object can only register one delegate for each event has been removed. For most cases, dispatching events should be faster, as dispatching an event now needs less dynamic memory allocations.
- fixed SF# 3178109: getNodeByPath() changes: getNodeByPath() and getNodeByPathNS() have been moved to Poco::XML::Node. Furthermore, when invoked on a Poco::XML::Document, the behavior has changed so that the document element is now included when traversing the path (previously, traversal would start at the document element, now it starts at the document). The path expression can now start with a double-slash, which results in a recursive search for the path's first element in the DOM tree.
- fixed SF# 3382935: String data being truncated using ODBC, and SF# 2921813: Wrong implementation of the ODBC string binding

## Release 1.4.1p1

### Summary of Changes

- Poco::Mutex is now a recursive mutex again on Linux (this was caused by an unfortunate feature test for PTHREAD_MUTEX_RECURSIVE which did not work on Linux as PTHREAD_MUTEX_RECURSIVE is an enum value and not a macro)
- Poco::Net::SecureSocketImpl::abort() now only shuts down the underlying socket connection and does not free the SSL object, due to multithreading issues.

## Release 1.4.1

### Summary of Changes

- fixed SF# 3150223: Poco::BinaryReader cannot read std::vector correctly
- fixed SF# 3146326: Poco::SharedMemory issue
- made Poco::Net::HTTPSession::abort() virtual
- added Poco::Net::SecureStreamSocket::abort() to immediately close a SSL/TLS connection without performing an orderly SSL/TLS shutdown.
- fixed SF# 3148126: Poco::Net::HTTPSClientSession destructor (!) throws an IOException. Added try/catch block to Poco::Net::SecureSocketImpl destructor.
- added additional constructor to Poco::Net::HTTPSClientSession, taking both a socket and a session object.
- Poco::Net::HTTPSession::abort() now also can be used with a Poco::Net::HTTPSClientSession.

- added additional options to configure script
- added additional documentation to Poco::Net::HTTPClientSession
- Poco::Net::HTTPClientSession::receiveResponse() closes the connection if an exception is thrown while reading the response header. This ensures that a new connection will be set up for the next request if persistent connections are used.
- improved Poco::Net::MultipartDecoder performance by reading directly from streambuf
- improved performance of Poco::Base64Encoder, Poco::Base64Decoder, Poco::HexBinaryEncoder and Poco::HexBinaryDecoder by working directly with the given stream's streambuf.
- improved performance of MessageHeader::read() by reading directly from streambuf instead of istream.
- it is now possible to specify additional MIME part header fields for a MIME part through the Poco::Net::PartSource class.
- upgraded SQLite to release 3.7.4
- added experimental VxWorks support for VxWorks 5.5.1/Tornado 2.2 and newer. Please see the VxWorks Platform Notes in the reference documentation for more information. Currently, the VxWorks is untested; full support will be available in release 1.4.2.
- fixed SF# 3165918: Poco::DynamicAny fails to convert from string to float
- fixed SF# 3165910: Poco::Net::MessageHeader does not accept HTTP conforming header
- made Poco::Task::cancel() virtual so that tasks can implement custom cancellation behavior.
- added optional argument to Poco::Util::WinRegistryKey constructor to specify additional flags (in addition to KEY_READ and KEY_WRITE) for the samDesired argument of RegOpenKeyEx() or RegCreateKeyEx().
- improved Poco::BasicEvent::notify() performance by avoiding an unnecessary heap allocation.
- added additional well-known port numbers to Poco::URI: rtsp, sip, sips, xmpp.
- added Poco::Net::MediaType::matchesRange()
- improved invalid socket handling: a Poco::Net::InvalidSocketException is now thrown instead of an assertion when an operation is attempted on a closed or otherwise uninitialized socket.

## Release 1.4.0

### Summary of Changes

- Poco::Net::SSLManager: documentation fixes, code cleanup
- Poco::Net::SSLManager: renamed PrivateKeyPassPhrase event to PrivateKeyPassphraseRequired
- added Poco::Net::HTTPServerRequestImpl::socket() to get access to the underlying socket
- added Poco::Net::Socket::secure() to find out whether a given socket supports SSL/TLS
- added Poco::Net::SecureStreamSocket::havePeerCertificate()
- NetSSL: added support for turning off extended certificate validation (hostname matching)

- fixed SF# 2941231: Poco::Net::ICMPEventArgs out of bounds array access
- added PageCompiler sample
- added missing newline at end of xmlparse.c
- Poco::Glob can now be used with an empty pattern which will match nothing (patch from Kim Graesman)
- added support for HTTP proxy authentication (Basic authentication only)
- fixed SF# 2958959: Poco::XML::XMLWriter must encode CR, LF and TAB in attribute values as character entities.
- Poco::Net::HTMLForm now supports PUT requests as well (see <http://pocoproject.org/forum/viewtopic.php?f=12&t=2163&p=3930#p3930>)
- fixed SF# #2970521: Poco::FileOutputStream and file permissions. (also fixed in File class)
- removed an unused (and wrong) default parameter from EventImpl constructor for WIN32.
- added full support for session caching to NetSSL_OpenSSL
- fixed SF# 2984454: Poco::Util::Timer::scheduleAtFixedRate() works incorrectly
- fixed a bug in Poco::Util::Timer that could lead to high CPU load if the system clock is moved forward.
- added "system.nodeId" property to Poco::Util::SystemConfiguration
- added a note to Poco::Util::ServerApplication documentation regarding creation of threads
- added Poco::Net::IPAddress::broadcast() and Poco::Net::IPAddress::wildcard() to create broadcast (255.255.255.255) and wildcard (0.0.0.0) addresses.
- fixed SF# 2916154: Poco::Net::IPAddress::isLoopback() only works for 127.0.0.1.
- added build configuration for iPhone Simulator
- GNU Make based build system provides new variables: POCO_HOST_BINDIR, POCO_HOST_BINPATH, POCO_HOST_LIBDIR, POCO_HOST_LIBPATH and POCO_TARGET_* equivalents.
- Poco::Util::Application::initialize() and Poco::Util::Application::uninitialize() will now be called from within run(). This solves various issues with uninitialize() not being called, or being called inappropriately from the Application destructor. Please note that this change will break applications that use the Application class, but only call init() and not run().
- added /startup option to specify startup mode for Windows services (automatic or manual)
- fixed SF# 2967354: SecureSocketImpl shutdown/close problem
- fixed SF# 3006340: LinearHashTable grows even if key already exists
- fixed a particularly nasty Windows error handling issue that manifested itself on WinCE: WSAGetLastError() would be called after a std::string was created. The string creation could result in a heap operation which called a Windows API to allocate memory. This would reset the GetLastError() error code. Since WSAGetLastError() is just an alias for GetLastError(), the actual error code from the socket operation would be lost.
- upgraded SQLite to 3.7.3
- added —header-prefix option to PageCompiler
- fixed SF# 3003875: SQLite data binding is broken
- fixed SF# 2993988: Issue with multiple calls to open()/close() on File*Stream
- fixed SF# 2990256: Poco::Net::HTMLForm and file uploads
- fixed SF# 2969227: Poco::DateTimeParser bug
- fixed SF# 2966698: Socket connect with timeout issue

- fixed SF# 2957068: Timeout value not picked up by proxy in Poco::Net::HTTPSClientSession
- fixed NetSSL_OpenSSL test runner for Poco::Util::Application class changes

- Added Poco::AbstractEvent::empty() to check whether an event has registered delegates.
- Poco::URI now correctly handles IPv6 addresses.
- Added Poco::Nullable class template.
- Added Poco::NullMutex, a no-op mutex to be used as template argument for template classes taking a mutex policy argument.
- Poco::XML::XMLWriter: fixed a namespace handling issue that occured with startPrefixMapping() and endPrefixMapping()
- Poco::Net::Context now allows for loading certificates and private keys from Poco::Crypto::X509Certificate objects and Poco::Crypto::RSAKey objects.
- Poco::Crypto::RSAKey no longer uses temporary files for stream operations. Memory buffers are used instead.
- fixed SF# 2957865: added Poco::UUID::tryParse()
- All Zip classes now use Poco::File[Input|Output]Stream instead of std::[i|o]fstream. UTF-8 filenames will now be handled correctly on Windows.
- fixed SF# 2902029: zlib flush support (Z_SYNC_FLUSH)
- added Poco::TextBufferIterator class
- fixed SF# 2977249: Use epoll instead select under Linux Poco::Net::Socket::select() and Poco::Net::Socket::poll() will use epoll under Linux if the Net library is compiled with -DPOCO_HAVE_FD_EPOLL. This is the default for the Linux build configuration (but not for the various build configurations targeting embedded Linux platforms).
- fixed SF# 2941664: Memory leak in Poco::DeflatingStream with zero-length streams (also fixed some other potential, but unlikely, memory leaks)
- fixed SF# 2946457: added Poco::Net::RejectCertificateHandler
- fixed SF# 2946621: Poco::Path bug with POCO_WIN32_UTF8
- fixed SF# 2929805: Environment::nodeId() does not work if no eth0 device exists
- Poco::Environment::nodeId() no longer throws if no hardware ethernet address can be determined. It returns an all-zero address instead.
- Added additional classification functions to Poco::Unicode class; made classification functions inline.
- added Poco::Ascii class for ASCII character classification. Methods of the Ascii class are now used instead of the standard library functions (std::isspace(), etc.) due to possible inconsistent results or assertions when the standard library functions are used with character codes outside the ASCII range.
- Poco::Net::MailMessage: fixed a bug in StringPartHandler that resulted in incorrect handling of non-ASCII data if char is signed.
- Improved Poco::Net::SMTPClientSession compatibility with various mail servers when using AUTH_LOGIN authentication.
- Added CRAM-SHA1 support to Poco::Net::SMTPClientSession
- Poco::Net::SMTPClientSession now also supports login with AUTH PLAIN.
- Added Poco::Net::SecureSMTPClientSession class, supporting STARTTLS for secure SMTP connections.
- fixed an issue with SharedMemory on POSIX systems, where a shared memory region would be deleted despite the server flag set to true (see http://pocoproject.org/forum/viewtopic.php?f=12&t=3494).
- PageCompiler: added a new page context directive, to allow passing custom context objects to the request handler.
- fixed Poco::Net::StreamSocketImpl::sendBytes() for non-blocking sockets
- added Poco::Net::DialogSocket::receiveRawBytes(), which should be used instead of receiveBytes() due to internal buffering by DialogSocket.
- Poco::XML::DOMParser: FEATURE_WHITESPACE has been renamed to FEATURE_FILTER_WHITESPACE (which now matches the underlying URI) and is now handled correctly (previously we did the exact reverse thing)
- added Poco::Util::AbstractConfiguration::remove() to remove a configuration property; added removeRaw() implementations to all implementations (contributions by Daniel Hobi and Alexey Shults).
- fixed NetSSL_OpenSSL compilation error on Windows with OpenSSL 1.0
- Added optional FIPS mode support to NetSSL_OpenSSL (contributed by Lior Okman). If OpenSSL has been configured and built with FIPS support, then FIPS support can be enabled by calling Poco::Crypto::OpenSSLInitializer::enableFIPSMode(true); or by setting the fips property in the OpenSSL configuration to true (see Poco::Net::SSLManager for details).
- fixed SF# 3031530: Ping and possible no timeout
- added Poco::Net::SocketReactor::onBusy(), called whenever at least one notification will be dispatched.
- fixed SF# 3034863: Compiler warning in Net/IPAddress.h with poco 1.3.2
- added support for CRAM-SHA1 authentication to Poco::Net::SMTPClientSession
- Poco::format(): arguments can now be addressed by their index, e.g. %[2]d
- Poco::Util::Timer::cancel() now accepts an optional boolean argument. If true is passed, cancel() waits until the task queue has been purged. Otherwise, it returns immediately and works asynchronously, as before.
- Poco::Net::HTTPServerResponse::redirect() now accepts an optional additional argument to specify the HTTP status code for the redirection.
- fixed a warning (BinaryReader.cpp) and error (ThreadLocal.cpp) in Foundation when compiling with Visual Studio 2010
- fixed a wrong exception in Poco::Net::POP3ClientSession
- Poco::Net::FTPClientSession and Poco::Net::SMTPClientSession now set the error code in exceptions they throw
- fixed a potential race condition with terminating a Windows service based on Poco::Util::ServerApplication
- fixed a bug in global build configuration file: explicitly setting POCO_CONFIG did not work on Solaris platforms, as it was always overridden by the automatically determined configuration.
- Added support for MinGW cross builds on Linux.
- Changed location of statically linked build products in the gmake-based build system. Statically linked executables are now in bin/$(OSNAME)/$(OSARCH)/static and no longer have the _s suffix
- The POCO_VERSION macro now is in its own header file, "Poco/Version.h". It is no longer available through "Poco/Foundation.h".
- added Poco::Net::HTTPCookie::escape() and Poco::Net::HTTPCookie::unescape().
- fixed SF# 3021173: Poco::Thread (POSIX) returns uninitialised value for OS priority
- fixed SF# 3040870: Poco::ThreadPool has no function to get assigned name
- fixed SF# 3044303: Can't use own config file on Solaris & OSARCH_64BITS ignored
- fixed SF# 2943896: Poco::AsyncChannel::log() blocks
- fixed a bug in Poco::Util::WinRegistryKey::getInt(): The size variable passed to RegQueryValueExW() should be initialized to the size of the output buffer.
- Added rudimentary support for compiling with Clang 2.0 (Xcode 4) on Mac OS X.
- New build configurations for Mac OS X: Darwin32 and Darwin64 for explicit 32-bit and 64-bit builds. Note that the default Darwin build configuration will build 64-bit on Snow Leopard and 32-bit on Leopard, but will always place build products in Darwin/i386. The new Darwin32 and Darwin64 configurations will use the correct directories.
- fixed SF# 3051598: Bug in URL encoding
- Poco::ThreadPool::stopAll() (and thus also the destructor) will now wait for each pooled thread to terminate before returning. This fixes an issue with creating and orderly shutting down a thread pool in a plugin. Previously, a pooled thread in a thread pool created by a dynamically loaded library might still be running when the plugin's shared library was unloaded, resulting in Bad Things happening. This can now no longer happen. As a downside, a pooled thread that fails to finish will block stopAll() and the destructor forever.
- NetSSL_OpenSSL: for a Poco::Net::SecureStreamSocket, available() now returns the number of bytes that are pending in the SSL buffer (SSL_pending()), not the actual socket buffer.
- Added Poco::Net::HTTPClientSession::secure() to check for a secure connection.
- Poco::Net::HTTPRequest::setHost() now does not include the port number in the Host header if it's either 80 or 443.
- log messages can now optionally include source file path and line number
- Poco::PatternFormatter can format source file path and line number (%U, %u)
- logging macros (poco_information(), etc.) now use __LINE__ and __FILE__
- new logging macros that incorporate Poco::format(): poco_information_f1(logger, format, arg) with up to 4 arguments
- added Poco::Net::HTTPSession::attachSessionData() and Poco::Net::HTTPSession::sessionData() to attach arbitrary data to a HTTP session.
- added additional constructors to zlib stream classes that allow passing a windowBits parameter to the underlying zlib library.
- fixed a potential error handling issue in Poco::Net::SecureSocketImpl.
- fixed SF# 3110272: Poco::Crypto::RSACipherImpl bug.
- fixed SF# 3081677: Poco::Util::ConfigurationView's getRaw not retrieving xml attributes.
- added basic support for Canonical XML and better pretty-printing support to Poco::XML::XMLWriter.
- Poco::Util::AbstractConfiguration now supports events fired when changing or removing properties.
- XML: added support for finding DOM nodes by XPath-like expressions. Only a very minimal subset of XPath is supported. See Poco::XML::Element::getNodeByPath(), Poco::XML::Element::getNodeByPathNS() and the same methods in Poco::XML::Document.
- Poco::Timer: If the callback takes longer to execute than the timer interval, the callback function will not be called until the next proper interval. The number of skipped invocations since the last invocation will be recorded and can be obtained by the callback by calling skipped().
- Poco::BinaryReader and Poco::BinaryWriter now support reading and writing std::vectors of the supported basic types. Also, strings can now be written in a different encoding (a Poco::TextEncoding can be optionally passed to the constructor).
- Windows Embedded CE (5.0 and newer) is now a supported platform.
- Poco::UUID::nil() and Poco::UUID::isNil() have been renamed to Poco::UUID::null() and Poco::UUID::isNull(), respectively, to avoid issues with Objective-C++ projects on Mac OS X and iOS where nil is a system-provided macro.
- Crypto bugfixes: Poco::Crypto::RSACipherImpl now pads every block of data, not just the last (or last two).
- Improved Crypto testsuite by adding new tests.
- Added new Visual Studio project configurations: debug_static_mt and release_static_mt (linking with static runtime libraries). The existing configurations debug_static and release_static have been renamed to debug_static_md and release_static_md, respectively. The suffixes of the static libraries have also changed. The static_md configurations now build libraries with suffixes md[d], while the libraries built by the static_mt configurations have mt[d] suffixes.
- Added Visual Studio project files for 64-bit builds.
- Added Visual Studio 2010 project files.
- Removed the use of local static objects in various methods due to their construction not being threadsafe (and thus leading to potential race conditions) on Windows/Visual C++.
- Fixed some warning on 64-bit Windows builds.
- The names of the Data connector libraries have changed. They are now named PocoDataMySQL, PocoDataODBC and PocoDataSQLite.
- fixed SF# 3125498: Linux NetworkInterface::list() doesn't return IPv6 IPs
- fixed SF# 3125457: IPv6 IPAddress tests are wrong
- Added initialization functions for the NetSSL_OpenSSL and Crypto libraries. These should be called instead of relying on automatic initialization, implemented with static initializer objects, as this won't work with statically linked executables (where the linker won't include the static initializer object). The functions are Poco::Crypto::initializeCrypto(), Poco::Crypto::uninitializeCrypto(), Poco::Net::initializeSSL() and Poco::Net::uninitializeSSL(). Applications using Crypto and/or NetSSL should call these methods appropriately at program startup and shutdown. Note: In release 1.3.6, similar functions have been added to the Net library.

### Incompatible Changes and Possible Transition Issues

- The behavior of Poco::Timer has been changed for the case when the callback function takes longer to execute than the given timer interval. In this case, the missed intervals are counted and the next callback will be at the next proper interval.
- Poco::XML::DOMParser: FEATURE_WHITESPACE has been renamed to FEATURE_FILTER_WHITESPACE (which now matches the underlying URI) and is now handled correctly (previously we did the exact reverse thing)
- Poco::UUID::nil() and Poco::UUID::isNil() have been renamed to Poco::UUID::null() and Poco::UUID::isNull(), respectively, to avoid issues with Objective-C++ projects on Mac OS X and iOS where nil is a system-provided macro.
- The names of the Data connector libraries have changed. They are now named PocoDataMySQL, PocoDataODBC and PocoDataSQLite.
- The existing Visual Studio build configurations debug_static and release_static have been renamed to debug_static_md and release_static_md, respectively. Also, the suffixes of the static library names have changed to match usual conventions.
- New static initialization functions for the Crypto and NetSSL_OpenSSL libraries have been added. These should be called instead of relying on automatic initialization, implemented with static initializer objects, as this won't work with statically linked executables (where the linker won't include the static initializer object). The functions are Poco::Crypto::initializeCrypto(), Poco::Crypto::uninitializeCrypto(), Poco::Net::initializeSSL() and Poco::Net::uninitializeSSL(). Applications using Crypto and/or NetSSL should call these methods appropriately at program startup and shutdown. Note: In release 1.3.6, similar functions have been added to the Net library.

- fixed SF# 2835206: File_WIN32 not checking aganist INVALID_HANDLE_VALUE
- fixed SF# 2841812: Posix ThreadImpl::sleepImpl throws exceptions on EINTR
- fixed SF# 2839579: simple DoS for SSL TCPServer, HTTPS server No SSL handshake is performed during accept() - the handshake is delayed until sendBytes(), receiveBytes() or completeHandshake() is called for the first time. This also allows for better handshake and certificate validation when using nonblocking connections.
- fixed SF# 2836049: Possible handle leak in FileStream If sync() fails, close() now simply set's the stream's bad bit. In any case, close() closes the file handle/descriptor.
- fixed SF# 2814451: NetSSL: receiveBytes crashes if socket is closed
- added a workaround for Vista service network initialization issue (an Windows service using the Net library running under Vista will crash in the call to WSAStartup() done in NetworkInitializer). Workaround is to call WSAStartup() in the application's main(). Automatic call to WSAStartup() in the Net library can now be disabled by compiling Net with -DPOCO_NET_NO_AUTOMATIC_WSASTARTUP. Also the new Poco::Net::initializeNetwork() and Poco::Net::uninitializeNetwork() functions can be used to call WSAStartup() and WSACleanup(), respectively, in a platform-independent way (on platforms other than Windows, these functions will simply do nothing).

- fixed SF# 2896070: Poco::Net::Context with non-ASCII paths
- added Unicode Surrogate support to Poco::UTF16Encoding. See Poco::TextEncoding::queryConvert() and Poco::TextEncoding::sequenceLength() for how this is implemented. Contributed by Philippe Cuvillier.
- fixed SF# 2897650: [branch 1.3.6] Net.SocketAddress won't compile for CYGWIN
- fixed SF# 2896161: Building on Windows fails when basedir has space in it
- fixed SF# 2864380: Memory leak when using secure sockets
- NetSSL_OpenSSL: the SSL/TLS session cache is now disabled by default and can be enabled per Context using Poco::Net::Context::enableSessionCache().
- fixed SF# 2899039: Wrong DST handling in LocalDateTime
- added Poco::RWLock::ScopedReadLock and Poco::RWLock::ScopedWriteLock (contributed by Marc Chevrier)
- added Poco::Thread::TID type, as well as Poco::Thread::tid() and Poco::Thread::currentTid() to obtain the native thread handle/ID

- On Windows, Poco::SharedLibrary::load() now uses LoadLibraryEx instead of LoadLibrary and uses the LOAD_WITH_ALTERED_SEARCH_PATH if an absolute path is specified. This will add the directory containing the library to the search path for DLLs that the loaded library depends upon.
- Mac OS X build settings now match those used by default Xcode projects, making linking the POCO libs to Xcode projects easier
- Replaced use of std::valarray in Poco::Net::ICMPEventArgs with std::vector due to issues with std::valarray together with STDCXX debug mode on OS X

## Release 1.3.5

### Summary of Changes

- added Poco::Crypto::X509Certificate::save()
- fixed a bug in Poco::Zip::Decompress that results in wrong paths for extracted files
- fixed a bug in Poco::Zip::ZipManipulator where the Zip file was opened in text format on Windows.
- added Poco::Crypto::X509Certificate::issuedBy() to verify certificate chain.

- Improved performance of HTTP Server by removing some string copy operations
- fixed SF# 2310735: HTTPServer: Keep-Alive only works with send()
- fixed appinf.com IP address in Net testsuite
- fixed RFC-00188: NumberFormatter and float/double numbers
- added —pidfile option to ServerApplication on Unix
- fixed SF# 2499504: Bug in Win32_Thread when using from dll (fixed also for POSIX threads)
- fixed SF# 2465794: HTTPServerRequestImpl memory leak
- fixed SF# 2583934: Zip: No Unix permissions set
- the NetSSL_OpenSSL library has been heavily refactored
- added NumberFormatter::append*() and DateTimeFormatter::append() functions
- use NumberFormatter::append() and DateTimeFormatter::append() instead of format() where it makes sense to gain some performance
- added system.dateTime and system.pid to Poco::Util::SystemConfiguration
- added %F format specifier (fractional seconds/microseconds) to DateTimeFormatter, DateTimeParser and PatternFormatter.
- fixed SF# 2630476: Thread_POSIX::setStackSize() failure with g++ 4.3
- fixed SF# 2679279: Handling of — option broken
- added compile options to reduce memory footprint of statically linked applications by excluding various classes from automatically being linked. See the POCO_NO_* macros in Poco/Config.h.
- fixed SF# 2644940: on Windows the COMPUTER-NAME and the HOSTNAME can be different
- added DNS::hostName() function
- added build configuration for iPhone (using Apple's SDK)
- basic support for AIX 5.x/xlC 8
- fixed a bug resulting in a badly formatted exception message with IOException thrown due to a socket-related error
- fixed SF# 2644718: NetworkInterface name conflict in MinGW
- added a missing #include to CryptoTransform.h
- fixed SF# 2635377: HTTPServer::HTTPServer should take AutoPtr<HTTPServerParams>
- replaced plain pointers with smart pointers in some interfaces
- upgraded to sqlite 3.6.13
- improved Data::SQLite error reporting
- Poco::Glob now works with UTF-8 encoded strings and supports case-insensitive comparison. This also fixes SF# 1944831: Glob::glob on windows should be case insensitve
- added Twitter client sample to Net library
- Fixed SF# 2513643: Seg fault in Poco::UTF8::toLower on 64-bit Linux
- Poco::Data::SessionPool: the janitor can be disabled by specifying a zero idle time.
- added Poco::Data::SessionPool::customizeSession()
- added support for different SQLite transaction modes (DEFERRED, IMMEDIATE, EXCLUSIVE)
- fixed a few wrong #if POCO_HAVE_IPv6 in the Net library
- added support for creating an initialized, but unconnected StreamSocket.
- added File::isDevice()
- added family() member function to SocketAddress,
- Data::SQLite: added support for automatic retries if the database is locked
- XMLConfiguration is now writable
- fixed an IPv6 implementation for Windows bug in HostEntry
- Timer class improvement: interval between callback is no longer influenced by the time needed to execute the callback.
- added PriorityNotificationQueue and TimedNotificationQueue classes to Foundation. These are variants of the NotificationQueue class that support priority and timestamp-tagged notifications.
- added Poco::Util::Timer class. This implements a timer that can schedule different tasks at different times, using only one thread.
- the signatures of Poco::NotificationQueue and Poco::NotificationCenter member functions have been changed to accept a Poco::Notification::Ptr instead of Poco::Notification* to improve exception safety. This change should be transparent and fully backwards compatible. The signature of the methods returning a Poco::Notification* have not been changed for backwards compatibility. It is recommended, that any Notification* obtained should be immediately assigned to a Notification::Ptr.
- SQLite::SessionImpl::isTransaction() now uses sqlite3_get_autocommit() to find out about the transaction state.
- improved SQLite data type mapping
- refactored Crypto library to make it independent from NetSSL_OpenSSL.
- added support for RSA-MD5 digital signatures to Crypto library.
- removed SSLInitializer from NetSSL library (now moved to Crypto library)
- added build configs for static libraries to Crypto library
- OpenSSL now depends on Crypto library (which makes more sense than vice versa, as it was before). Poco::Net::X509Certificate is now a subclass of Poco::Crypto::X509Certificate (adding the verify() member function) and the Poco::Net::SSLInitializer class was moved to Poco::Crypto::OpenSSLInitializer.
- added build configs for static libraries to Zip
- added batch mode to CppUnit::WinTestRunner. WinTestRunnerApp supports a batch mode, which runs the test using the standard text-based TestRunner from CppUnit. To enable batch mode, start the application with the "/b" or "/B" command line argument. Optionally, a path to a file where the test output will be written to may be given: "/b:<path>" or "/B:<path>". When run in batch mode, the exit code of the application will denote test success (0) or failure (1).
- testsuites now also work for static builds on Windows
- The IPv6 support for Windows now basically works (Net library compiled with POCO_HAVE_IPv6)
- fixed a potential error when shutting down openssl in a statically linked application
- added static build configs to Data library
- added Poco::AtomicCounter class, which uses OS-specific APIs for atomic (thread-safe) manipulation of counter values.
- Poco::RefCountedObject and Poco::SharedPtr now use Poco::AtomicCounter for reference counting
- fixed SF# 2765569: LoadConfiguration failing from current directory

### Incompatible Changes and Possible Transition Issues

- Some methods that have previously taken a plain pointer (to a reference counted object) as argument now take a Poco::AutoPtr instead. This shouldn't cause any problems for properly written code. Examples are Poco::NotificationCenter, Poco::NotificationQueue and Poco::Net::HTTPServer.
- Poco::Glob now works with and assumes UTF-8 encoded strings.
- Poco::Timer: the interval between callbacks is no longer influenced by the time needed to execute the callback.
- The Crypto and NetSSL_OpenSSL libraries have been refactored. NetSSL_OpenSSL now depends on the Crypto library (previously, it was vice versa).

## Release 1.3.3

### Summary of Changes

- Threads now have optional user-settable stack size (if the OS supports that feature)
- Events now support simplified delegate syntax based on delegate function template. See Poco::AbstractEvent documentation for new syntax.
- Cache supports new access expire strategy.
- Upgraded to SQLite 3.6.2
- Upgraded to PCRE 7.8
- added HttpOnly support to Poco::Net::HTTPCookie
- NetworkInterface now has displayName() member (useful only on Windows)
- Poco::Util::WinRegistryKey now has a read-only mode
- Poco::Util::WinRegistryKey::deleteKey() can now recursively delete registry keys
- Poco::File::created() now returns 0 if the creation date/time is not known, as it's the case on most Unix platforms (including Linux). On FreeBSD and Mac OS X, it returns the real creation time.
- Time interval based log file rotation (Poco::FileChannel) now works correctly. Since there's no reliable and portable way to find out the creation date of a file (Windows has the tunneling "feature", most Unixes don't provide the creation date), the creation/rotation date of the log file is written into the log file as the first line.
- added Environment::nodeId() for obtaining the Ethernet address of the system (this is now also used by UUIDGenerator - the corresponding code from UUIDGenerator was moved into Environment)
- added a release policy argument to SharedPtr template
- Socket::select() will no longer throw an InvalidArgumentException on Windows when called with no sockets at all. If all three socket sets are empty, Socket::select() will return 0 immediately.
- SocketReactor::run() now catches exceptions and reports them via the ErrorHandler.
- SocketReactor has a new IdleNotification, which will be posted when the SocketReactor has no sockets to handle.
- added referenceCount() method to Poco::SharedPtr.
- POCO now builds with GCC 4.3 (but there are some stupid warnings: "suggest parentheses around && within ||".
- Solution and project files for Visual Studio 2008 are included

### Incompatible Changes and Possible Transition Issues

The (now deprecated) Poco::HashFunction class template has been changed in an incompatible way. The member function formerly named hash() is now the function call operator. If you have defined your own HashFunction classes, you have to update your code. Sorry for the inconvenience.

On Windows, POCO now builds with Unicode/UTF-8 support (POCO_WIN32_UTF8) enabled by default. If you need the previous (1.2) behavior, remove the corresponding #define from Poco/Config.h
