• Fix a bug where a disabled move error message could freeze a battle
• Fix recharge Move data
• Fix a bug in simple heurstic player choose move (#376)
• Fix a bug where some moves referencing other moves would get two pp uses instead of one (#355)
• Fix a bug where indented PS teams couldn't get parsed (#367)
• Fix max PP count. Now assumes maxed out PPs (#355)

Better data utilities

• poke_env.utils are now poke_env.stats
• Create data submodule
• Create GenData class
• Bug fix: active pokemon is not set correctly when not all mons are selected in team-preview

This release is a step towards gen 9 support. Preliminary gen 9 support is available on #351

Synchronous gym api

• Rework gym API to be synchronous
• Add misc effects
• Fix misc bugs
• Update data
• Drop python 3.6 support and add python 3.10
• Revamp inits

• Unify ability representation
• Better handling of hiddenpower, especially in gens < 8
• Add missing AbstractBattle abstract_property values
• Add Battle.opponent_can_mega_evolve / Battle.opponent_can_z_move properties

Better move parsing

• Update data files
• Improve move message parsing
• Better capping of number of moves (to 4)
• Clarify Battle.weather typing

Minor:

• calling EnvPlayer.step when reset wasn't called raises an Exception, as per some open ai gym implementations

Minor bug fixes and improved env_player.reset

This release adds:

• handling of -swapsideconditions messages
• log.info /log pm messages instead of log.warning them
• Fix hidden power Moves initialization - their type is now correctly inferred
• Fix hanging env_player.reset when called before the current battle is finished
• env_player.complete_current_battle now forfeits instead of performing random moves until the battle finishes
• env_player.step(-1) forfeits the battle

Add stackable conditions + minor fixes
