 Unfortunately the released JSQLParser-5.2 shows a performance deterioration caused by commit [30cf5d7](https://github.com/JSQLParser/JSqlParser/commit/30cf5d7b930ae0a076f49deb5cc841d39e62b3dc) related to `FunctionAllColumns()`.
 This has been resolved in JSQLParser 5.3-SNAPSHOT and JMH benchmarks have been added to avoid such regressions in the future. Further all `LOOKAHEAD` have been revised one by one, and we have gained back a very good performance of the Parser.
 
+As per March-2026, the productions `Condition()`, `RegularCondition()` and `AndExpression()` have been refactored successfully. This resulted in a massive performance boost and seem to have solved most of the performance issues.
