CairnMP 2.3.1 (beta)

This beta uses protocol 15. Taking up someone else's piton is now reported to the
host, and the race and revive features changed their messages: every player in a lobby
must run CairnMP 2.3.1.

Changed

• Free solo keeps its word: death is final. A camp no longer brings the fallen back in
  this mode; they keep watching, as the mode says.

Fixed

• The game mode picked in the panel is applied: every lobby used to be created as Rope
  team. Every client now knows the lobby's mode from the moment it joins.
• /recap with three or more players no longer starts a stream of replies that never
  ends.
• Race: the host referees the finish, so two climbers topping out together no longer
  each see themselves as the winner. A latecomer no longer misses the start, and is told
  who already won.
• Downed climbers stay clipped to their partner, so carrying them costs endurance as
  intended. The revive prompt's collider is kept on ghosts, and a ghost that spawned as
  a placeholder is rebuilt as the real climber once the game can provide it.
• Who is down is known to latecomers too. The last climber to fall now tells the others,
  and a run that ends no longer announces the climber back on their feet.
• Rescues are confirmed by the host before the healing item is spent: two rescuers
  reaching the same body no longer lose an item each, and a rescue from out of reach is
  refused. A call back to camp is only accepted from a climber actually at one.
• Calling the fallen back to camp with R works, and a teammate sitting at camp counts
  as still standing.
• Ending a session while down plays the death out instead of leaving the climber in a
  dead body with no menu.
• Pitons: taking up a piton someone else placed removes it for everyone, so it can no
  longer end up in two bags. Pitons placed while a player is loading, camping or still in
  the menu are no longer lost. After a reload, saved pitons are recognised instead of
  being announced again as duplicates.
• A client that restarts its game and rejoins can give and drop items again straight
  away.
• Ground items: an item being picked up keeps its place, so a full ground no longer
  destroys it. Stale ground-item icons are cleaned up.
• Trail marks are drawn again after a camp or a reload, and climb trails are kept.
• A camping player's ghost is hidden instead of standing at the world origin, and
  players who left no longer come back as frozen ghosts.
• A stuck bivouac flag no longer suspends synchronization every few seconds.
• Voice: output is kept for 30 seconds of silence, so the start of a sentence is no
  longer lost; mutes survive scene changes; the speaking icon stays visible.
• The CairnMP settings button is no longer duplicated after a camp, and the fallback
  panel no longer leaks resources each time it opens.
• Quitting to the main menu from the pause menu no longer leaves the chat closed and the
  main menu counted as gameplay.
• One malformed packet no longer stops the host from reading the others, and animation
  positions are bounded like every other position.
• Accepting a Steam invite while already in a lobby leaves that lobby first. A failed
  create or join updates the panel from the game thread.

Compatibility

• Protocol 14 → 15: ClientPitonRecovered and ServerPitonRecovered are new, and
  the race and revive feature contracts changed. All lobby members must use this
  exact version.
• The loader is MelonLoader under its own name again, installed by the launcher in the
  game's MelonLoader folder.

Beta notes

• These fixes are covered by the test suites and build against the game, but none has
  been played in a live two-client session yet.
• This is the first release published from GitHub: the launcher installs it directly,
  without the releases console.
