Ok, it's been almost 10 months since I last published a release. Guilt release time!

  • Handle overly lengthy static enum initialisers.
  • Fix possible loop in conditional condenser.
  • Optional resugaring of unobfuscated retrolambda.
  • Relink external constants where possible
  • Be more restrictive inlining lvalues in the presence of possible side effects
  • Fix Constantlinks relinking (thanks Marcono1234)
  • Docs fixes (thanks YannisBft)
  • Fix race when decompiling with multiple drivers in parallel
  • Support enum changes in Java 15+
  • Tweak record support for Java 15+ changes
  • Fix stack overflow when determining original bytecode location (when showing bytecode loc)
  • Support for sealed classes
  • Fix possible infinite loop in changeassignment rewriter
  • Improve byte data performance (thanks CoolMineman)

As usual, please check the change log for the real details, (and for linked issues, thanks to all those who submit issues!)

Various improvements for ECJ specific patterns.
Improvement for methodhandle LDCs (thanks graxcode)
Fix bug with inline assignment inside constructor prelude
Various nasty assert cases
Handle malicious signatures causing stack overflow
Handle unusual static initialiser access.
Propagate bytecode location (in theory, this can be used to improve debugger support!)
Handle dynamic descriptor mismatch obfuscation
Handle duff device switch bytecode
Handle basic integer (eg /0) control flow obfuscation. (--antiobf true)
Handle .getClass control flow obfuscation.
Don't resugar negative sized arrays (thanks x4e)
Handle basic loop index obfuscation (confusing offset constants).
(optional with --constobf) fold decompiled constant expressions (thanks ColE) CFR won't do this unless asked as it tries to be true to the bytecode!
Tweak recovery order to avoid using more aggressive passes if they don't improve things.
Fix for package info annotation order.

Too much to list (see commits since previous release) - I really must cut releases more often, but:

Lots of annotation fixes (perfect recovery of annotations is a whole new dimension of pain). (Thanks Marcono1234 (contrib))
Support for Java 14 record types
Support for Java 14 instanceof pattern matching
Update switch expressions to use final 'yield' syntax instead of 'break'.
Fix for issue with immediately accessed array.
Several fixes around cast ambiguity (Thanks Marcono1234)
Handle unverifiable jumps (example)
Tweak class names when O/S can't handle them
Several fixes for ECJ generated code (Thanks Marcono1234)
Improve literal formatting (Thanks SimonWanner (contrib))
Explicitly display receiver parameters if required by annotations. (Thanks Marcono1234)
Token stream dumper for API usage (Thanks Cubixity (contrib))
