Thanks to alienBOB. n/openssh-8.2p1-x86_64-1.txz: Upgraded. Potentially incompatible changes: * ssh(1), sshd(8): the removal of "ssh-rsa" from the accepted CASignatureAlgorithms list. * ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1 from the default key exchange proposal for both the client and server. * ssh-keygen(1): the command-line options related to the generation and screening of safe prime numbers used by the diffie-hellman-group-exchange-* key exchange algorithms have changed. Most options have been folded under the -O flag. * sshd(8): the sshd listener process title visible to ps(1) has changed to include information about the number of connections that are currently attempting authentication and the limits configured by MaxStartups. x/mesa-19.3.4-x86_64-2.txz: Rebuilt.

+QLibrary/Unix: do not attempt to load a library relative to $PWD
+
+I added the code in commit 5219c37f7c98f37f078fee00fe8ca35d83ff4f5d to
+find libraries in a haswell/ subdir of the main path, but we only need
+to do that transformation if the library is contains at least one
+directory seprator. That is, if the user asks to load "lib/foo", then we
+should try "lib/haswell/foo" (often, the path prefix will be absolute).
+
+When the library name the user requested has no directory separators, we
+let dlopen() do the transformation for us. Testing on Linux confirms
+glibc does so:
+
+$ LD_DEBUG=libs /lib64/ld-linux-x86-64.so.2 --inhibit-cache ./qml -help |& grep Xcursor
+ 1972475: find library=libXcursor.so.1 [0]; searching
+ 1972475: trying file=/usr/lib64/haswell/avx512_1/libXcursor.so.1
