These are mainly small changes in how source-locations are ascribed to synthetic expressions, plus three real changes:
- The comment extractor is performing better presumably due to improvements in the underlying representation
- *= /= and %= operations are once again extracted correctly; presumably their origin information has been fixed
- Reference to a static final Java field can lead to more constant propagation than before
The last one might be a minor nuisance to someone trying to find references to such a field.
