This will likely be the last release in the 4.x series as a large rewrite of the injection code and some impressive performance gains are incoming. Changes · Support for 1.17-1.18.x · Add long jump pose · Fix entity tracker · Remove stray debug stak · Fix NPE with PlayerInfoData · Fix player protocol version · Fix a memory leak · Improve auto wrapper And, as always, thank you to my generous sponsors who support the project!

First, a big shoutout to my GitHub sponsors for supporting the update to 1.17. Monthly and one-time donations of any amount are greatly appreciated. Changelog · Support for Java 16 · Support for Minecraft 1.17.x · Metrics improvements · Fix performance issue with list converter · Add converter for Paper's adventure API · Add modifier for internal classes via internal structure · Only set chat packet UUID if not already set · Support for unix domain sockets in paper · Properly translate MotD to components for new RGB colors

Huge thank you to my GitHub sponsors @PaulBGD and @Yive. Sponsorships and donations are greatly appreciated and help keep me motivated. Additions · Support for 1.16.x · Support for Java 15 (#1025) · Serialization to/from byte arrays (#875) Improvements · Cache perm gen bean to improve performance (#876) · Removed legacy code and dependencies · Better support for MCP packet names (#862) Bug Fixes · Skip non-vanilla packets (#959) · Fix issue with Chat Extensions · Various other bug fixes As always, report any issues you encounter on GitHub Issues

Merry Christmas, everyone! My gift to y'all is a new release: Additions · MC 1.14.x and 1.15.x support · VillagerData wrapper, long array NBT type, new packets Bug Fixes · Fixed entity tracking issues with Citizens and Holographic Displays · Fixed block data deep clone · Fixed error filtering reports · Fixed linkage error on enable · Fixed statistic wrapper error Improvements · Improved legacy packet name compatibility · Reduced exception wrapping with ViaVersion If ProtocolLib has made your life easier, please consider donating. It really means a lot! This update requires that you run Spigot, not CraftBukkit (Paper should be good). While this was an inadvertent change, we have been building against Spigot for years now and there really isn’t any reason to use CB over Spigot.

Additions · API method to check for temporary players · 1.12.x and 1.13.x support · Ability to clone NBT tags, as well as new 1.13.x classes · Support for Java optionals and 1.13.x particles Bug Fixes · Fixed an issue with the component array converter · Fixed an issue reloading (still not recommended) · Fixed an issue with 1.8.0 support · Fixed an issue with the Bukkit updater, treat Paper as "Spigot" · Fixed an issue where the byte buffer in a WirePacket was not released Improvements · Java 9/10 support (still not recommended due to reflection performance) · Reworked internal conversion and cloning logic to be cleaner and more efficient · Replaced MCstats (RIP) with bStats · More consistent packet metadata API · Handle AIR item stacks properly · Use real players wherever possible instead of temporary players Note to developers: This will be the last release of the ProtocolLib-API module. Lots of people have been having issues with the plugin failing to load, and the best solution I see is to recombine the modules. Resuming with 4.5.0, use ProtocolLib as a whole as your dependency.

Additions · Added support for 1.12 · Added new ChatType enum Improvements · Updated to Java 8 · Restored getProtocolVersion functionality Bug Fixes · Fixed issues with packet type deprecation · Fixed a typo that broke 1.8.0 compatibility · Fixed an issue with another fork If you like ProtocolLib, please leave a positive review or consider donating!

Additions · Added debugging mechanism to print out all packet contents (/packetlog) · Added missing fallingdust particle Improvements · Made Sound conversion more robust Bug Fixes · Removed unnecessary updater spam · Fixed component parsing in 1.8 If you like ProtocolLib, please leave a positive review or consider donating!

Additions · Added modifier for ItemStack lists · Added mechanism to clone NonNullLists Improvements · Updated for 1.11-1.11.2 · Avoid looking up classes multiple times to improve performance · Avoid errors with invalid entities

I realize versioning got a little ...complicated... since I decided to drop legacy support. So, with the release of 4.1.0, the main branch of ProtocolLib will support 1.8 and up. The legacy branch, 3.7.0, will support 1.7.10 and below. I encourage all developers who added ProtocolLib version checks to adjust these checks accordingly or remove them altogether. Now, on to the meat of the update. Additions: · Support for Minecraft 1.8.x · Conversion methods for WirePackets · Modifiers for UUIDs, Directions, and NBT Lists Improvements: · Made ProtocolLib locale independent · Cache null classes to improve performance · Wrap all serializable objects in DataWatchers Bug Fixes: · Fixed issues with cloning DataWatchers · Fixed missing TileEntity write methods · Fixed issues with "proxied" players (non-Bungee) Development build equivalent: http://ci.dmulloy2.net/job/ProtocolLib/325/ A full list of changes can be found here: https://github.com/dmulloy2/ProtocolLib/commits/master

This update contains a few bug fixes before work begins on 4.1. API Improvements: · Added block data to the cloning mechanism · Reworked the component array modifier to work with 1.9.4 and up · Automatically wrap and unwrap values in Optionals General Improvements: · Updated to 1.10 and 1.10.2 Bugs, etc: · Fixed another entity tracking issue with Paper · Improved error messages for entity tracking · Improved error message when the login packet class doesn't exist

This is a collection of bug fixes from the 4.0.0 release. Updater: · Auto download is now disabled by default · Build numbers are no longer taken into account · A warning is now printed if the updater section is missing Performance: · Fixed the registry being refreshed more often than necessary

Hello everyone! It's time for a major release, the first one since 2013. The reason for this is major changes in the project structure and removal of backwards compatibility. For server owners: ProtocolLib will no longer provide backwards compatibility. The released version will only support the latest minor version of Minecraft, so in this case it will only support 1.9.x. The reasoning behind this is two-fold: First, it would have been a pain and required lots of extra code to maintain backwards compatibility with 1.7 and 1.8 due to the changes in 1.9. Second, the public API remains relatively constant between updates, so as long as you're using the proper version of ProtocolLib for your server, plugins will work just fine. For developers: The biggest change in 1.9 involves data watchers. Mojang added a few new data watcher related classes, most notably the data watcher object and the data watcher serializer. Watcher objects are generally created and registered in entity classes and store the item's index and serializer. Serializers serialize watcher values into the packet stream. What this means for developers is that now, in order to register a new object in a data watcher, you must specify a valid watcher object, and by extension, a serializer. Check the documentation for the WrappedDataWatcher and its subclasses here: http://ci.dmulloy2.net/job/ProtocolLib/javadoc/com/comphe… The API has been split off into its own module, ProtocolLib-API. Developers are encouraged to use it as the dependency. I plan to do more with the new project structure in the future. Changes since 3.7: · Added modifiers for ItemSlot, Sonds, Hands, SoundCategory, and MobEffects · Added the ability to use user-created enums (See here) · Full support for 1.9-1.9.4 · More DataWatcher improvements · Fixed block data errors · Fixed false update notifications with beta releases · Fixed an issue with chat components

Hello everyone! This is a beta build of ProtocolLib with 1.9 support. It's a beta build because it has not been fully tested, nor is it backwards compatible. I will work on restoring backwards compatibility and further testing for the full release. A side effect of the 1.9 update was the changes made to data watchers. Basically, Mojang added a bunch of bloat, so I was forced to add that same bloat to ProtocolLib, which broke backwards compatibility. Special thanks to @NavidK0 for his help with data watchers and testing with LibsDisguises, as well as all of you who provided bug reports and support in the issues section! If you like ProtocolLib, please leave a review or consider donating. It really means a lot.
