Product Updates

Swift SDK

PowerSync Swift SDK: v1.13.1

Kotlin Multiplatform SDK

PowerSync Kotlin SDK: v1.11.2

[IMPROVED] SQLiteConnectionPool implementations are now responsible for dispatching blocking SQLite callbacks to an appropriate dispatcher (e.g. Dispatchers.IO) after obtaining a connection lease — this bounds worker pool growth to the actual connection pool size under high concurrency. Note: custom SQLiteConnectionPool implementations will need to be updated. (PR #337)

JavaScript/Web SDK

JavaScript Web Client SDK: v1.37.0

[IMPROVED] Database lock management moved into workers instead of clients, laying the groundwork for future concurrent read support; previously exported internal connection management classes have been removed. (PR #889) Potentially breaking: While this is mostly an internal change, it updates how tabs communicate with workers. Upgrading should not be an issue when using bundlers like vite which add file hashes to worker paths. If you manually load workers you've copied into your app sources, please make sure the workers are upgraded along with the SDK. Workers from earlier @powersync/web versions will not work.
