May 13, 2023 Update Version 1.1.1

General Features:
- Lobbies - Added ability to assign a tag to a Lobby
- Possible tags are: none, newcomer, casual, veteran, god
- Lobbies - Added ability to filter lobbies based on tags.
- Online - added GGPO Frame Delay option
- Training Room - Frame Advantage - this feature is currently a work in progress and is known to be inaccurate for ground/wallbounces (such as Aki’s Standing Heavy).
Gameplay Features:
- Air Tech and Ground techs are now performed by holding any attack button when a tech is possible.
- You are still able to influence the direction of an air tech by holding the respective direction while teching
- After an Air Tech, you are now invulnerable until hitting the ground OR performing any aerial action
Infinite Prevention System (IPS)
- When IPS invulnerability is triggered in midair, you are now invulnerable until either teching or hitting the ground.
- This contrasts with the old IPS System, where invulnerability would run out as soon as the tech window began.
General Bugfixes
- System Mechanics - STAR Meter - Fixed issue where having exactly 250 meter would not allow you to perform an EX move.
- System Mechanics - Burst - Fixed issue where Burst would not cancel out knockback momentum
- Stage - Fixed bug where certain combos could not be performed on the Idol Showdown Stage. Now all stages should be identical.
- Tutorial - Bugfix where Superchat cancel and Combo into specials tutorials would sometimes not pass the player when the condition was performed.
- Fixed issue where frame data could be inconsistent at the start of a match
- General Online stability updates
- General Localization and text fixes.
