April 2026 (2026-04) – Powersync-service: Focused on stabilizing test suite and CI, delivering cross-database reliability improvements. Delivered two main enhancements: (1) Test stability: fixed a race condition in BinLogListener tests for MySQL 5.7 by ensuring rows are written before dropping test tables; (2) CI/DB init robustness: added a SQL Server Agent running check and retry logic for enabling CDC on the checkpoints table. These changes reduce flaky tests and CI setup failures, enabling faster, safer releases across MySQL and MSSQL environments. Commits these changes include 92bc81220ff54e3e9e6ff77e2f2688fc88dd59c3 and 468831e305a286c923e91992f95233364d6543d4.
