This release fixes a number of bugs and adds some small features.

• This release removes support for older versions of libcrypto. OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1. Note that these versions are already deprecated by their upstream vendors.

• ssh(1): allow forwarding Unix Domain sockets via ssh -W.

• All: fix a number of memory leaks and unreachable/harmless integer overflows.
