• Fixed a hang in rpki-client(8) by properly waiting for exiting openrsync(1) processes.
• Made FFS2 the default for newfs(8).
• Changed install images called *.fs to *.img to accommodate some UEFI bootloaders.
• Restored VGA fonts on VT switch, preventing an unusable screen when switching to a VT with a custom VGA font from X.

• Began initial development of an OpenBSD/powerpc64 port.
• In tmux(1):
  • Added an option to set the pane border lines style as single lines, double or heavy, simple or number (the pane numbers).
  • Added a client flag 'active-pane' which stores the active pane in the client and allows it to be changed independently from the real active pane stored in the window.
  • Added a -D flag to run in non-daemonized mode.
  • Added a customize mode (C) where keys and options can be browsed and changed.
  • Added M-+ and M-- to expand and collapse all items in tree mode.
  • Changed refresh-client -F to -f and added -f flags to attach-session and switch-client.
  • Added -e for new-session to set environment variables.
  • Added the 'e' key in buffer mode to open the buffer in an editor.
  • Added -W and -T flags to command-prompt to only complete a window and a target.
• Ensured that a TLSv1.3 server has provided a certificate before attempting validation.
• Implemented kqueue(2) support for video(4).
• Updated to xkbprint 1.0.5.
• Updated to libXxf86dga 1.1.5.

• Set ddb(4) "/t" to show a trace via TID on all architectures.
• Updated nsd(8) to 4.3.1.
• Added -rls1_3 and -no_tls1_3 options to openssl(1) s_server.
• Preserved group/world read permission on known_hosts files across runs of ssh-keygen(1) "-Rf /path".
• Fixed an iked(8) policy lookup edge case for simultaneous transport and tunnel mode SAs.
• Enabled the TLSv1.3 server in openssl(1).
• Improved reporting of remaining power with batteries of different capacities in acpi(4).
• Allowed specifying -d multiple times in slowcgi(8).
• Added bgpctl(8) support for VPNv6 in the family option of the "show rib" command.
• Fixed two out-of-bounds array accesses in ioctl code pathways in wscons(4).
• Made "reason" parsing in bgpctl(8) more generic and introduced it to the "reload" command.
• Added an optional "domain name" acme-client.conf(5) option allowing use of multiple domain sections with the same name and creation of an rsa and an ecdsa key for the same domain name.
