About Stirling-PDF
Stirling PDF is clearing the decks — six weeks of hotfixes ahead of a promised big release.
Every release in this window is corrective. 2.14.3 fixes tool operations failing on Debian 12 and Fedora 44, concurrency problems on merge, an automation bug in image removal, and crashes on 2GB PDFs, plus Linux startup and a Windows ARM64 test build. Before it, 2.14.2 patched Postgres user-data loading, 2.14.1 stopped PostHog loading before opt flags were read and fixed certificate signing, and 2.13.2 covered security fixes and desktop performance. The one feature release is 2.14.0, which added hardware token signing via PKCS#11 smart cards and OS certificate stores on desktop.
