OpenSSL 3.0.0 released
[Development] Posted Sep 7, 2021 13:53 UTC (Tue) by corbet
Version 3.0 of the OpenSSL TLS library has been released; the large version-number jump (from 1.1.1) reflects a new versioning scheme.
Most applications that worked with OpenSSL 1.1.1 will still work unchanged and will simply need to be recompiled (although you may see numerous compilation warnings about using deprecated APIs). Some applications may need to make changes to compile and work correctly, and many applications will need to be changed to avoid the deprecations warnings. We have put together a migration guide to describe the major differences in OpenSSL 3.0 compared to previous releases.
OpenSSL has also been relicensed to Apache 2.0, which should end the era of "special exceptions" needed to use OpenSSL in GPL-licensed applications. See this blog entry and the changelog for more information.
