PostgreSQL connection strings now accept URI syntax and quoted parameters, making configuration cleaner for modern deployments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Security-conscious users will want to upgrade promptly: the bundled expat dependency has been updated from 2.7.5 to 2.8.1 to address CVE-2026-41080 and CVE-2026-45186. SQLite, libpng, and the LZMA SDK have also been refreshed with upstream fixes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One breaking change to note: the&nbsp;<code>%c<\/code>&nbsp;specifier in&nbsp;<code>Poco::DateTimeFormatter<\/code>&nbsp;now correctly formats centiseconds rather than deciseconds. Code relying on the previous (incorrect) behavior will need adjustment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other highlights include fixes to&nbsp;<code>AbstractEvent<\/code>,&nbsp;<code>Logger::shutdown()<\/code>,&nbsp;<code>UnbufferedStreamBuf<\/code>, and the&nbsp;<code>DateTimeParser<\/code>, plus build improvements for CMake, MSVC, and Apple linkers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Grab the source and assets from the&nbsp;<a href=\"https:\/\/github.com\/pocoproject\/poco\/releases\/tag\/poco-1.15.3-release\">official release page on GitHub<\/a>.
