Release 1.6

• Fixed a crashing issue caused by MP3 errors and osu!lazers importing problems (#10 )
• Slightly improved the downloading system to deal with timeouts. Untested
  • The osu! website will block you from bulk downloading to save bandwidth
• Fixes to beatmap scanning
  • Do note that the game itself has problems importing, causing the app to not find anything
• You can now login using your username
  • osu! has now disabled email logins

Release 1.5

• Added: Synchronization with osu library.
  This will synchronize every song installed in the game to your selected folder. Any files that do not belong to the game will be deleted. Please be careful to not lose any important data.
• Some bug fixes and UI enhancement.

Release 1.4

Auto import beatmaps.
You can now import the beatmaps you downloaded automatically. Requires launching the game.

Release 1.3

Fixed Linux compatibility

• If your distro doesn't have xdg-utils (All X.org desktop environments have this installed), hyperlinks will not work. There are no workarounds. Sorry! ¯\(ツ)/¯

Various UI fixes and bug fixes

Release 1.2

Compatibility with the newest versions of the game.
Handled the cooldown when you are downloading a ton of maps (That's a server-side cooldown. Not mine)
Some UI enhancements
Allowing setting game executable location
Auto game detection for macOS, Windows, and Arch Linux based users (If you are installing through AUR).
macOS users should now have full access to all features when exporting songs.

This app should now work on all OSes. (Not tested. As I don't have anything other than Windows).
I currently won't be providing full support on Linux as there isn't official support for the game yet.

Update: JDK 11 has removed JavaFX, a critical component for displaying windows components and rendering this release unusable. If you currently have Java 11 as default, please remove it (or change the default setting) and install Java 8.
If you simply installed JRE (NOT JDK), you are using Java 8. You don't need to do anything.

Release 1.1

Added Chinese traditional translation.
You can now download beatmaps without video.
macOS users can now export songs with limited functionality.

Keep in mind that the game doesn't have an official build for anything other than Windows. The app allows you to specify the game installation directory upon startup (Windows will be done automatically).

Release 1.0

Requires Java 8. Both files work the same.
Please note that the game is still in development at the time of releasing this. This version only supports Windows.
There will be updates when other platforms are supported.
