1.6.3 release,

* LICENSE and copyright holder added in each file. If you are making a closed source product, all you need to do is make sure you aren't obfuscating my files. * BukkitMoveEvent deprecated, you may copy the event and recreate it on your end in your project, BukkitMoveEvent will most likely be removed in the next minor update. * CancellableEvent interface added, implemented in all built in events as they are all cancellable. * Asynchronous injecting and uninjecting is no longer done on the Netty threads, it is now done using java's Executor Service's threadpool * GitHub Wiki API usage Guide has been rewritten, should finished done today or in a few days

Author	SHA1	Message	Date
retrooper	ce2603549b	1.6.3 release, * LICENSE and copyright holder added in each file. If you are making a closed source product, all you need to do is make sure you aren't obfuscating my files. * BukkitMoveEvent deprecated, you may copy the event and recreate it on your end in your project, BukkitMoveEvent will most likely be removed in the next minor update. * CancellableEvent interface added, implemented in all built in events as they are all cancellable. * Asynchronous injecting and uninjecting is no longer done on the Netty threads, it is now done using java's Executor Service's threadpool * GitHub Wiki API usage Guide has been rewritten, should finished done today or in a few days	2020-09-01 16:53:31 +02:00

retrooper	33131f4fcd	Merge pull request #30 from NikV2/master Uninjections async are now configurable in the settings(can cause reload bugs), I’d rather have setIdentifier() deprecated for one patch version(1.6.1) then in 1.16.2 we remove it completely, basically if then user doesn’t set identifier to anything, we will generate a random one, low priority for injecting and uninjecting players in PacketEvents class.	2020-08-28 01:57:42 +02:00
