April 2026 monthly summary focusing on delivering a focused UI sorting improvement in the Eclipse Platform UI. Implemented Tree Sorting Improvements in AbstractTreeViewer to correctly handle TreePathViewerSorter and TreePathViewerComparator, ensuring stable and predictable sort order in tree views. The change is captured in commit d0eb817372ead45fff370ae91560344e88b793b6 with the message 'Fix sorting when using a TreePathViewerSorter in AbstractTreeViewer'. This work reduces user confusion, improves UI consistency across the platform, and enhances maintainability of the sorting logic.

January 2025: Stabilized the Eclipse PDE AST parsing pipeline by delivering a targeted update to support modern Java language features. Key changes include upgrading the AST parser to the latest JLS to fix crashes related to pattern matching in switch statements, and replacing the deprecated JLS4 constant with getJLSLatest(). The patch is tracked in eclipse-pde/eclipse.pde (commit fcf76585b10488e31df4b6cc7b7758f002631a7a). This work improves parser reliability, reduces downstream tooling risk, and enhances future-proofing for PDE users.
