A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Fixed: Crash when cycling through monster types or name prefixes in the dex filter screen. Backend: Upgraded pygame from 2.1.3.dev8 to 2.1.3 Backend: Upgraded overrides from 3.1.0 to 7.3.1 Backend: Upgraded h5py from 3.6.0 to 3.8.0
Minimum save file version is now 1.2.4 Fixed: Audio plays at slightly different speeds on different computers. Fixed: Charm bar incorrectly displays guaranteed charm when it is merely very likely. Balance: Adjusted the formula used to calculate how much XP is required to level up so that monsters with higher power tend to require more XP to level up. Backend: Upgraded pygame from 2.1.2 to 2.1.3.dev8 Backend: Upgraded tcod from 13.1.0 to 15.0.0 Backend: Upgrade numpy from 1.21.4 to 1.21.6
UI: Added a bar in the battle screen for the average roll per enemy monster (in other words, if the probability of charming the monster is 100%, then the bar will be full). Fixed: Monster dex text sometimes includes a mutated version of the "This is stub" Wikipedia message.
Fixed: Crashes in various UI screens due to Proćemon sprites that haven't been loaded yet.
New Feature: Dex filters. You can filter Proćemon in the dex screen by minimum damage, power, charmed status, first letter, and type. Significantly sped up save file loading.
Minimum save file version is now 1.2.0 New Feature: Encode/Decode Proćemon. You can encode and decode Proćemon to share them with friends! From the dex, you can find a window that encodes the Proćemon to a string. You can copy that string to the clipboard and place it somewhere else. Once a day, you can go the Decoder Room in Infinity Corporation to paste an encoded string. Doing so will decode the monster, add it to your dex, and add the Proćemon to your army. Fixed: The dex includes an extra fourth Proćemon after the intro fight that sometimes doesn't match the one Prof. Tree had. Now, that
Fixed several end-game crashes
Fixed: Crash if you lose the game. UI: Show the dex entry of a fusion immediately after fusing. Input: Press either the confirm or cancel button to exit a dex entry (previously, only the cancel button exited a dex entry).
Animation: Optimized the generation speeds of many move animations. Animation: Added two new move animations. Fixed: One of the move animations never animates. Fixed: Occasional crash for one of the move animations.
Fixed: Various crashes when a player wins a battle. Fixed: If you lose against the final boss, you still win the game. Fixed: Extremely rare bug that could happen if the random name of a save file is TEMP.hdf5 Fixed: The game will list a temporary save file (TEMP.hdf5) as a valid save file.
Fixed a bug that made the game unwinnable. UI & Sound: Improved feedback when the player wins a battle. Added a sound effect for when a monster levels up and when a monster is charmed. When a monster is added to the dex, the dex entry appears. UI: Added an asterisk on the dex screen for each monster that you've charmed. This is not backwards-compatible: older saves don't have this data, but will start to update with charmed data now as you charm monsters.
Fixed: Rare softlock when you warp into a world because you're boxed in by a trainer. Now, if you warp into a world within a trainer's line of sight, they will immediately initiate battle rather than wait for you to move (if you defeat the trainer, they disappear, thus removing the softlock).
Fixed: Crash if the gamepad is not supported. Now, the gamepad fails silently without the game crashing. Fixed: Bad default key bindings for Steam Deck. To use the new key bindings, delete this file: ~/procemon_rpg/config.json where ~ is your home directory. Then, run the game.
