• It is now possible to add a fixed delay (in seconds) between waves with the new per-arena setting next-wave-delay.
• The new per-arena setting join-interrupt-timer makes it possible to add a "delay" to the join and spec commands. If the player moves or takes damage during this delay, the command is interrupted. This should help prevent exploits on PvP servers.
• Right-clicking is now allowed in the lobby. This makes it possible to activate blocks like buttons and levers.
• Snow and ice no longer melts in arenas.
• Much of the parsing logic has been rewritten so that MobArena now logs more user-friendly errors when it encounters invalid values in the config-file.
• If MobArena fails to load due to config-file errors, it now enters a type of "error state". In this state, it responds to all commands (except for the reload command) with a short message explaining why it's disabled.
• It is now possible to reload config-files with /ma reload.
• The reload command now also reloads global settings, e.g. the global messenger prefix.
• Armor stands can now be placed in arenas and lobbies.
• The new command /ma ready (/ma rdy for short) can be used as an alternative to the iron block for readying up.
• Total experience is now correctly stored, reset, and restored on arena join/leave. This fixes a potential bug where total experience could increase in the arena, but levels and progress would still get reset at arena end.
• The per-arena setting keep-exp returns. If enabled, any experience collected during an arena session is added as a reward on death or when the final wave is reached.
• Waves will no longer intermittently progress at double frequency in some arena sessions. This long-standing bug where waves progress at "double speed" has finally been fixed.

Thanks to:

• Sait for adding the /ma ready command
• PrinceIonia, Nesseley, and Diamond_Cat for help with test of dev builds
