1.13 prep is still moving along, I've been spending a lot of time working on the backend tools to make decompiling and working with 1.13 a bit easier. Cpw is still working on the re-write of FML for Java9+ and 1.13. 

However, development on 1.12 has not stopped, we've gone through and cleaned up a lot of things, as well as properly introduced a better library management system. So, it's about time for a new release.

Dependencies:

For a long time Forge has supported the ability to have multiple jar files extracted at startup from mods. Allowing modders to distribute required dependencies in a single download for end user convince. However, this feature has not been used often. After getting some modder feedback I have re-written the majority of this system. We need volunteers to write full documentation for this feature, however here is a quick rundown.

Mods will now be extracted to a central maven style libraries directory. Forge will attempt to find this using the normal launcher layout, however the path can be overridden using "-Dforge.lib_folder={LibraryFolder}"

Mods CAN be automatically moved to this libraies folder by Forge, however this is disabled by default due to people thinking it'll be confusing to users. Enable it using  "-Dforge.enable_auto_mod_movement=true"

To define a contained dependency modders must add the "ContainedDeps" entry to their MANIFEST file. This is a space separated list of files in the mod jar to be extracted. The files can be located under the jar root, or META-INF/libraries/.

Libraries can specify a maven style artifact identifier in their MANIFEST file, and it will be extracted to the correct library folder. Example: Maven-Artifact: net.minecraftforge:forge:1.12.2-14.23.4.2703

If two mods contain a dependency on the same maven artifact, the highest version will be loaded. This fixes issues where two mods ship a API, and one crashes because the older version was used.

For 3rd party dependancies that do not have the Maven-Artifact manifest entry, you may specify a custom MANIFEST by adding a {FullJarNameIncluding.jar}.meta file next the original file.

More information and examples should be forthcoming as modders start working with this feature. So don't be afraid to ask.
