Vineflower 1.12.0 is the next major release of Vineflower, improving how variables are handled, beautifying the decompiler output, improving Kotlin support, as well as dozens of bug fixes and smaller features. Thanks to all the contributors who submitted patches for this release!
NOTE
This release contains two different jars. The "regular" jar, with no classifier, contains both the main decompiler and the three bundled plugins. The "slim" jar, with the "-slim" classifier, contains only the main decompiler itself. If confused, just get the regular jar as usual.
The full changelog is as follows:
