Hi, I just finalized the language files for the upcoming 3.0.0 release, so if you have the time and interest, I'd appreciate pull requests with updates for your translations (also accepting new languages if you know any missing ones, or know someone who'd want to help).

Pings for previous contributors:
@Vexatos @davrodrila @Haruki1 @AndreiTS @MCEventHorizon @3TUSK @NatsuArashi

If you don't want to be pinged for translations in the future, please post a comment and I'll keep it in mind if I decide to go insane and make another major update in a few years :P

If you are interested...

• Folder with all language files

Existing translation files were updated with new texts and minor corrections. Many older texts were also rewritten:

• For larger changes, I replaced previous translations with English text so it'll need new translations:

  • bs.menu, bs.sprint.hold.info - total rewrites
  • bs.sprint.toggle.info - added a second line
  • bs.flyBoost.info - added mention of spectator mode
  • bs.command.info - shortened text
  • Everything under the categories In-game messages and Configuration

• For smaller changes, I kept the previous translation, but it'd be good to update those as well:

  • bs.sprint.toggle, bs.sneak.toggle - removed parentheses, but you can keep them if it looks better that way
  • bs.flyBoost, bs.disableMod - shortened text
  • bs.menu.info, bs.doubleTapping.info, bs.runAllDirs.info, bs.disableMod.info - stylistic changes
  • bs.command.disableMod - improved clarity

You can also view the modified lines in en_us if you want to see the exact changes in wording, and an example update of cs_cz. Feel free to comment if you have any questions.

Notes

• Don't translate _comment entries
• If you're using en_us as the base, discard lines 63-66
• Make a Pull Request against the master branch, which is currently on Minecraft 1.14.x

Thanks!
