+This project is unmaintained; for an actively maintained successor, see [JD-GUI-DUO](https://github.com/nbauma109/jd-gui-duo).
+
+Many changes have been made, making the project unlikely to be merged into the original one:
+* [ANTLR](https://www.antlr.org/) and the outdated JDK7 grammar [Java.g4](services/src/main/antlr/Java.g4) are dropped and replaced by [Eclipse JDT Core](https://github.com/eclipse-jdt/eclipse.jdt.core) to take advantage of nice features such as type bindings, compiler errors/warnings, and a more convenient AST
+* [ProGuard](https://github.com/Guardsquare/proguard) is dropped as it made the project harder to maintain, the build really slow, and the errors harder to diagnose
+* JRE is now generated by [jre-builder](https://github.com/nbauma109/jre-builder) for the needs of the project in version 25 to take advantage of the latest libraries compiled in newer versions of Java
+* Other decompilers are supported (CFR, Procyon, Fernflower, Vineflower, JADX) with the [transformer-api](https://github.com/nbauma109/transformer-api) (forked from [helios-decompiler](https://github.com/helios-decompiler/transformer-api))
+* Use of [JarComp](https://activityworkshop.net/software/jarcomp/index.html) and [NetBeans diff module](https://github.com/nbauma109/netbeans-visual-diff-standalone) to provide a comparison feature
