Release 1.7.8p3 upgrades the bundled Expat XML parser to release 2.2.1 which fixes some
vulnerabilities. Upgrading from earlier releases is highly recommended.

As it happened in my case, the Visual Studio 2017 installer (Community Edition, but maybe also other editions) may break an existing Visual Studio 2008 installation. Specifically, when you run Visual Studio 2008 under WoW64 (e.g., from a TeamCity agent or similar), the Visual Studio $(WindowsSdkDir) variable will be undefined after running the 2017 installer, causing builds to fail as the toolchain cannot find the Windows SDK. A fix that worked for me can be found here. Took me some time to fix the issue (specifically, because it only happened under TeamCity), and happened again after upgrading from VS2017 RC to final.

Release 1.7.8 of the POCO C++ Libraries is available.

This is a maintenance release containing significant improvements and bugfixes in the Foundation, Net, Zip and MongoDB libraries. Furthermore, the bundled SQLite, zlib, PCRE and double-conversion libraries have been upgraded to current releases.

Incidentally, release 1.7.8 marks the 12th anniversary of the first public POCO C++ Libraries release on February 21, 2005, as evident from the CHANGELOG, which obviously also lists all changes in this latest release.

Release 1.7.7 of the POCO C++ Libraries is available.
This maintenance release contains bugfixes and improvements in the Foundation, JSON, Net, NetSSL, Data/ODBC, Data/SQLite and Zip libraries.
On Apple platforms, the latest Xcode 8.2 toolchains are supported and an IPv6 DNS issue on iOS and related platforms causing rejection of apps during App Store validation has been fixed. The NetSSL_OpenSSL library now can be compiled with OpenSSL 1.1.x.
As usual, the full list of changes in in the CHANGELOG. Upgrading to this release is recommended.

Release 1.7.6 of the POCO C++ Libraries is available.
This release contains bugfixes and improvements in the Foundation, XML, Util, Net, Data/MySQL and Zip libraries. A special focus of this release was correcting a couple of non-critical issues reported by static code analysis tools.
As usual, the full list of changes in in the CHANGELOG. Upgrading to this release is recommended.

I recently did a review of our project with regards to the Core Infrastructure Initiative (CII) Best Practices, in order to ensure we’re following industry best practices with POCO.

Things looked very good, with only a few best practices missing, which I have fixed in the meantime:

• Updated the CONTRIBUTING.md file to include a statement on reporting security issues via email and added a link to that file to README.md.
• Updated the instructions for preparing a release in the Wiki to include running clang-analyzer.
• Enabled HTTPS for the project website (using a Let’s Encrypt certificate and certbot-auto), which was actually most of the work (including fixing all links, etc.).
• Ran clang-analyzer on the code base for peace of mind 😉

We can now proudly show the CII Best Practices badge on our GitHub page:

The POCO C++ Libraries are being used in a lot of important projects in lots of different areas, from server and desktop applications, mobile apps to Internet of Things and connected devices in factories, homes and buildings, infrastructure as well as vehicles. Following established best practices and giving our best to ensure high-quality releases is my main priority.

Release 1.7.5 of the POCO C++ Libraries is available.

Release 1.7.4 of the POCO C++ Libraries is available.
