2024.86 - 22 October 2024

- Fix failure on concurrent channel open/close.
  This was a regression in 2022.82, reported by rsflo in Github #321.
    failed assertion in common-channel.c:705: !channel->sent_close

- Print remote host after "Login attempt for nonexistent user" log entry to
  assist fail2ban. Fix from MichaIng, the format changed in 2020.79

- Dropbear now exits with exit status 0 on SIGINT/SIGTERM. This is a more
  graceful behaviour for "systemctl stop dropbear".
