.NET SDK

PowerSync .NET SDK: v0.1.2 (Beta)

[ADDED] Attachment APIs: AttachmentQueue manages offline-first file attachment sync (upload, download, delete, archive), mirroring the implementation in our other SDKs. Register a watched query and supply local and remote storage adapters; the queue handles the full lifecycle automatically. See the docs. (PR #68) [ADDED] Mac Catalyst support. The SDK now targets net9.0-maccatalyst and the setup script downloads the Mac Catalyst xcframework automatically. (PR #64)

Kotlin Multiplatform SDK

PowerSync Kotlin SDK: v1.12.0

[IMPROVED] Native Apple platforms: the SQLite core extension is now linked directly into the SDK - no external dependency required. Remove any references to https://github.com/powersync-ja/powersync-sqlite-core-swift.git (Swift Package) or the powersync-sqlite-core CocoaPod from your project. This also fixes dyld crashes on iOS after SDK updates. (PR #344) [IMPROVED] The Kotlin sync client implementation was removed. The more performant Rust-based sync client is now the only implementation. (PR #342)
