 ## [Unreleased]
+### Added
+- (API) MobArena's internal command handler now supports registering pre-instantiated subcommand instances. This should make it easier for extensions to avoid the Singleton anti-pattern for command dependencies.
+
 ### Changed
 - The regex pattern for the player list command is now less greedy, so it will only match on `/ma players`, `/ma playerlist`, and `/ma player-list`. The previous pattern matched on anything that starts with `player`, which rendered the `/ma player-stats` command in MobArenaStats impossible to invoke.
