This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.

Subject: [PATCH] Use Optimized Collections
|
|
|
|
Swap out CraftBukkit LongObjectHashMap with Long2ObjectOpenHashMap
|
|
Swap out Integer key HashMap for a Int2ObjectOpenHashMap For ChunkProviderServer
|
|
|
|
Amaranth, the creator of LongObjectHashMap, tested it vs fastutil and determined fastutil to be 3x faster
|
|
and could not create anything faster than fastutil.
|
|
|
|
These collections are super fast as seen
