CHANGELOG

New features – Tweaks – Bug fixes – Internal changes

Deleted users who haven’t logged in during the past week and have less than 10 minutes of playtime, and also users who haven’t logged in during the past 4 weeks and have less than an hour of playtime, and also users who haven’t logged in during the last 12 months and haven’t set an e-mail. Note that users with any purchase are never
deleted.
Window size is now a multiple of 4 pixels when HQ2X mode is on (prevents font blurring)
Cleaned up predicate which controls display of in-game pause menu.
Translations: Changed “gamepad” to “controller”
Translations: PROGAMERHINT and ANONYMIZEHINT: Detached “(requires logout/login”) into their own separate phrase (REQUIRESLOGOUTLOGIN and REQUIRESMISSIONRESTART)
Can now ‘detect’ Win11 as an operating system.
Translations: Changed MULTIPLAYERVISIBILITY “multiplayer mode” to “participants”
UVE no longer “ticks slowly” during MODE_FROZEN. This was a Windows-specific thing that causes problems with code that expects graphics to be working during tick() (e.g. Loader, FontQuad2GlyphCache)
Removed BASS_Update(100) (now relying on BASS’s thread to do updating). Should improve audio latency.
Removed bTickWhilePaused
UVE is no longer automatically raised to MODE_OK during start-up. It starts in MODE_FROZEN and raises to MODE_OK during the first frame.

Fixed ScissoredList not reaching the end under backlog of mouse-wheel events.
