ProtocolLib v4.1.0

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)

ProtocolLib v3.7.0

Note: This version only supports Spigot 1.7.10 and below. For current versions, see here: https://github.com/dmulloy2/ProtocolLib/releases/

This version contains critical bug fixes from the 3.6.x branch for 1.7.10:

• Fixes issues related to MCPC / Cauldron / Thermos / Whatever they're calling it nowadays
• Fixes issues related to entity tracking, especially with Paper
• Backports a few critical performance fixes, including:
  • Fixes performance issues with background compilation
  • Ensure the packet registry is updated only when changes occur
  • Cache null classes to improve performance

A full changelog can be found here: https://github.com/dmulloy2/ProtocolLib/commits/3.7.0

Since 1.7.10 is 2 years old by now, only critical bugs will be addressed. No feature requests or minor bugs will be accepted.

ProtocolLib v4.0.2

This update contains a few bug fixes before work begins on 4.1.

ProtocolLib v4.0.0

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 should 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/comphenix/protocol/wrappers/package-summary.html

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

ProtocolLib v3.6.5

Additions

• /protocol dump - useful information for debugging
• Optional update checking and automatic downloads
• WrappedBlockData#getData()
• BlockPosition#toLocation(World)

Improvements

• Updated to 1.8.8
• 1.9 future proofing

Bug Fixes

• Fixed lag issues with background compilation
• Fixed issues with server pings and ClosedChannelExceptions
• Fixed conflict checking when the plugin folder was changed
• Fixed the StreamSerializer for 1.8
• Fixed issues with custom packets
• Many fixes with backwards compatibility

Note: If the auto updater section is missing from your config, you must regenerate it or add the section manually to disable updates.

This will be the last version of ProtocolLib that supports Java 6!
