OpenSSH 9.5 released

OpenSSH 9.5 is out. Significant changes include a transport-level pingmechanism and keystroke timing obfuscation:

This attempts to hide inter-keystroke timings by sending interactive traffic at fixed intervals (default: every 20ms) when there is only a small amount of data being sent. It also sends fake "chaff" keystrokes for a random interval after the last real keystroke. These are controlled by a new ssh_config ObscureKeystrokeTiming keyword.
