March was a big month for PowerSync, with major projects like **improved concurrent connection scaling** and the release of **client SDKs for two new frameworks: .NET and Node.js**. We’re seeing an acceleration in both new users getting started with PowerSync and users deploying PowerSync into production. Let’s go!

## Service Performance Optimizations

We’ve made significant performance improvements that enable even better scalability of _concurrent_ connections. Specifically, we’ve implemented caching of parameter queries and bucket data to reduce redundant computation during incremental sync. We’ve also optimized Postgres transaction replication by batching multiple operations into a single flush to the bucket storage.

## Prioritized Sync Available On All Beta+ SDKs

Prioritized sync allows you to make critical data available to users immediately — like showing a dashboard or login state — while non-essential data continues syncing in the background. All SDKs in Beta status or above now support this.

## .NET Client SDK (Alpha)

Our .NET client SDK brings real-time sync and offline-first capabilities to .NET desktop and server apps, sharing the same core features as our other client SDKs. Support for mobile applications is up next, including .NET MAUI bindings.We’ve confirmed WPF apps are supported and will be shipping a demo app soon.

## Node.js Client SDK (Alpha)

We're excited to announce the alpha release of our Node.js Client SDK, bringing PowerSync’s real-time sync capabilities to Node.js environments, such as server-side apps, CLI tools and Electron apps.

## Swift and Kotlin Multiplatform SDKs Improved

We've updated our Kotlin Multiplatform and Swift SDKs to unify read and write concurrency across iOS, Android, and JVM platforms. All platforms now support concurrent reads (multiple read operations happening at the same time) resulting in faster UI updates. Both of these SDKs will be in V1/GA within the next week or two.

[See release notes for the Swift SDK](https://releases.powersync.com/announcements/powersync-swift-sdk) and [KMP SDK](https://releases.powersync.com/announcements/powersync-kotlin-multiplatform-sdk)

## FlutterFlow Guide Update: Handling Attachments
