- Update to openssh 9.9p1:
= Future deprecation notice
* OpenSSH plans to remove support for the DSA signature algorithm
in early 2025. This release disables DSA by default at compile
time. DSA, as specified in the SSHv2 protocol, is inherently
weak - being limited to a 160 bit private key and use of the
SHA1 digest. Its estimated security level is only 80 bits
symmetric equivalent.
OpenSSH has disabled DSA keys by default since 2015 but has
retained run-time optional support for them. DSA was the only
mandatory-to-implement algorithm in the SSHv2 RFCs, mostly
because alternative algorithms were encumbered by patents when
the SSHv2 protocol was specified.
This has not been the case for decades at this point and better
algorithms are well supported by all actively-maintained SSH
implementations. We do not consider the costs of maintaining
DSA in OpenSSH to be justified and hope that removing it from
OpenSSH can accelerate its wider deprecation in supporting
cryptography libraries.
= Potentially-incompatible changes
* ssh(1): remove support for pre-authentication compression.
OpenSSH has only supported post-authentication compression in
the server for some years. Compression before authentication
significantly increases the attack surface of SSH servers and
risks creating oracles that reveal information about
information sent during authentication.

Correctly parse DISPLAY variable for cases where it contains an IPv6 address

(which should - but not always is - in (square) brackets).
