Available via updater 2009-01-26 22:23 GMT+9.
Available via installer [uploading].
Changelog:
Multiplayer:
(+) New multiplayer modes: Team VS and Tag Team VS.
(+) Multiplayer games allow password protection and setting a max player limit before opening the match.
(+) Can join matches already in progress and see scores.
(+) Can see which matches you already have the beatmap for based on the colour of the match in the lobby.
(+) If you are the last person left in an in-progress match and quit, you will still remain host.
(+) Password status and mode displayed in multiplayer lobby.
(+) Can skip outro sequences.
Beatmapping/Editor:
(+) Added support for a second custom sampleset. Uses hitnormal2.wav etc. You can now use up to 6 samplesets in a single song (including defaults).
(+) New transformation options added to Storyboard Editor (Vector Scale, Flipping).
(+) Inheriting timing sections can allow for double/half bpm changes.
(+) New tapping algorithm. Very intelligent - give it a try. For more details read this post.
(*) Editor help overlay brought up-to-date with newer editor layout (thanks Nharox).
(*) Restricted circle size difficulty settings to 3-7.
Gameplay:
(+) Accuracy is now displayed at all times in-game.
(+) "Hit Lighting" effects. Look closely as your hits splash colours on the playfield.
(+) New "Progress Pie" displays your progress through a song in a more compact and appetising display!
(+) Mouse4(?) now skips during gameplay.
Song Selection:
(+) New song selection sort mode - "Last Played".
(+) Song selection screen layout and design improvements. Get a feel for the song before playing as the background image fills the screen.
(+) Ctrl-Enter for instant autoplay of the selected song. Ctrl-A to toggle.
osu!direct:
(+) osu!direct shows thumbnails and plays audio previews for all maps!
(*) Double-clicking osu!direct pickup links instantly starts download.
Chat/Online/Bancho:
(+) Button spam is filtered from chat client side (no more 'zxzxzxzzxzxxzzxx').
(+) Event tracking support for BanchoBot. Now displays high scores and achievement unlocks.
Misc:
(+) Title screen is slightly affected by song volume.
(*) Changed F6 at main menu to open the "Jump To" window.
Fixes:
(*) /np shows editing status if required.
(*) Many multiplayer crash fixes.
(*) Fixed some bancho disconnect issues.
(*) Fixed bancho refusing to reconnect after some disconnections.
(*) Changed bancho connection method to be more reliable on server failures.
(*) Changed message popup behaviour to be aware of the chat ticker. No more overlaps.
(*) Fixed avatars not loading properly on main menu/multiplayer game scoreboard.
(*) Fixed unpausing sometimes not working.
Performance Improvements:
(*) Decreased load time of heavily storyboarded maps. Sprites are dynamically loaded during breaks.
(*) Decreased load time on skin select screen by around 55%.
(*) Direct3D renderer now uses background threads to load textures (storyboard, song select background). Huge performance increase.
(*) Increased beatmap import performance (relative to how many beatmaps you have in your local database).
(*) OpenGL render engine performance improvements (especially with framesync off - changed default to off).
(*) Video playback optimisation - double performance in some cases.
