Cygwin currently uses OpenSSL 3.0 LTS, which has a planned EOL of
September 2026.  The update to the new 3.5 LTS will most likely happen
in the next month or two, most likely based on version 3.5.5 w/ Fedora
43 or rawhide patches, depending on how extensive the work on adapting
to Cygwin turns out to be this time around.


This release provides the latest OpenSSL 3 LTS release and uses the
Fedora 39 patches (without FIPS and foreign CPU architecture support).
The following packages have been uploaded to the Cygwin distribution:

* openssl-3.0.19-1
* openssl-perl-3.0.19-1
* libssl3-3.0.19-1
* libssl-devel-3.0.19-1

The following MinGW64 packages are available:

* mingw64-i686-openssl-3.0.19-1
* mingw64-x86_64-openssl-3.0.19-1

The OpenSSL toolkit provides support for secure communications between
machines. OpenSSL includes a certificate management tool and shared
libraries which provide various cryptographic algorithms and protocols.

This release includes a patch that is meant to solve problems with
threaded applications / libraries using the openSSL DLL:
