A pretty solid release

A lot of bugs regarding the aliases have been fixed! I'd like to thank @ShaneBeee, @Efnilite and @Blueyescat as they have been of a lot of help by testing the fixes we've made. This release wouldn't have happened without your help guys.

Remember that even if many bugs have been fixed, this is a beta release, not a stable one. Please don't run this on a production server until you have tested that everything works as expected.

That being said, here are the changes:

• Updated WorldGuard hook (make sure to have WG 7.x or Skript may not work properly).
• Added a connect effect for teleporting players through BungeeCord servers
• Enhanced the tab-completion of command arguments (Closes #1600)
• Added 1.13 particles and potion effects (Thanks to @ShaneBeee)
• Added support for all 1.13 entities (thanks to @ShaneBeee, closes #1635)
• Added an effect for sending titles and subtitles (thanks to @ShaneBeee, closes #1213)
• Added swim related events and condtions (1.13 only, thanks to @ShaneBeee)
• Added the ability to change inventory names (thanks to @TheLimeGlass)
• Added the ability to change difficulty of a world (thanks to @TheLimeGlass)
• Improved englishness of documentation (thanks to @Efnilite and @JRoy)
• Re-added the block change effect that got lost in a merge (Closes #1626)
• Fixed the kill effect having a strange behaviour with players (thanks to @TheLimeGlass)
• Fixed block events firing when they had a common alias group (Closes #1567)
• Fixed the break event having a different entity event-value in some cases (Closes #1561)
• Fixed the place event not firing in cases where it should (Closes #1614)
• Fixed a bug with item's durability making it not run on 1.12 and older (Closes #1617 and #1608)
• Fixed the item with lore expression removing previous meta from items (Closes #1620)
• Fixed a bug where entities would be treated as item types (Closes #1631)
• Fixed item names not being always the same (Closes #1658)

A bit more stable release

Everything is finally starting to look stable! 1.12 and older Minecraft versions might be not so stable with this build, but this is (hopefully) quite usable on 1.13.

Also, this is a beta release, not stable one. Except bugs, and don't run this outside of a test server until you have tested whether there are critical bugs or not.

More bugfixes

Warning: this is an unstable release. It will likely break your server. Use it only if you're interested in helping us find and fix bugs.

Might be time for beta build after this; testing might even prove 1.13 to be perfectly usable. 1.12 has also got some bug fixes; 1.11 and earlier are untested, and will likely be tested once we're in beta.

1.12 + a pile of bug fixes

1.12 appears to be working, but is probably even more buggy than 1.13. Feel free to submit any bugs you find now. Same goes for earlier versions (1.9, 1.10, 1.11), but they've received pretty much no testing yet.

• Fixed Minecraft 1.12 not working
• Fixed some regressions due to commits being lost in merge conflicts
• Updated build system (Gradle and ecj)

More bugs found

Warning: this is an unstable release. It will likely break your server. Use it only if you're interested in helping us find and fix bugs.

1.13 test release

Warning: this is an unstable release. It will likely break your server. Use it only if you're interested in helping us find and fix bugs.

An inventory update

The few previous releases were, if not small, not huge either. Well, this one isn't. Lots of new features, old bugs fixed and so on. Also, probably some new bugs. Test before you put this to your public server.

If you use addons, this release might cause you some trouble due to inventory slot handling changes. Known problems:

• TuSKe prints errors on startup, but appears to work otherwise

The addon developers have been notified. If you are an addon developer and were not noticed, open an issue or contact me in some other way.

• Added more information to Skript's exceptions (thanks @Pikachu920)
• Added support for modifying remaining air better (thanks @TheLimeGlass)
• Added an item despawn event (thanks @TheLimeGlass)

If your functions broke, try adding

execute functions with missing parameters: false

in your config.sk. It will revert back to the old, weird, behaviour, where functions are not executed at all when any parameter provided does not exist.

• Fixed entities being parsed as inventory holders (closes #1126)
• Fixed a conflict that custom inventory syntax had (closes #1202)
