We've published a blog post with more details powersync.com/blog/emudhra-sā€¦

Security Notice Regarding Compromised eMudhra Intermediate CA

Compromised eMudhra CA keys could allow an attacker intercepting outbound TLS connections to impersonate JWKS endpoints or databases, potentially bypassing authentication or exposing data.

We've released 1.27.1 of the PowerSync Service on Docker Hub. It contains mitigations for the eMudhra Intermediate CA Compromise. The compromise could affect JWKS fetching and TLS connections for source databases. It is recommended to upgrade now. github.com/powersync-ja/poweā€¦

Update CA bundles by rkistner Ā· Pull Request #854 Ā· powersync-ja/powersync-service

Update to NodeJS v24.22.0. Update system CA bundles in the Docker image - likely unused. Use the latest Mozilla CA bundles for NodeJS. This is a smaller change than switching over to system bundles...

We love SQLite, but working with booleans can have some rough edges due to SQLite's absence of a dedicated bool type. We shipped "fixed_booleans_in_json" in 1.27 of the PowerSync Service, which now preserves boolean literals in synced JSON. Check it šŸ‘‡

one of my beliefs is that most apps basically solve the same engineering problems over and over again: - a design system - a sync engine - transactional database and if you just extract these out and solve them correctly, "vibe coding" any app on top becomes trivial

We were approached by @Microsoft to add support for @DocumentDB as a source database for PowerSync. It has been a pleasure working with their team to get this shipped, and they blogged about some of the capabilities and use cases: devblogs.microsoft.com/documā€¦

The PowerSync CLI now has a --dry-run flag for all deploy commands, to review changes before deploying. If you're paranoid about agents running amok, this could help. Available in v0.10.2

Sometimes your app requires fast user switching. If you call disconnectAndClear(), then each time a user switches they need to re-download all their data. To make user switching faster, consider preserving local data when disconnecting: db.disconnectAndClear({ soft: true })

Supabase Select is happening today! Say hi to @k081e if you see him there. The event gave us an excuse to ship something we've always wanted to: a streamlined Supabase setup experience in PowerSync Cloud. Building sync into your app has never been simpler!

The integration creates a dedicated replication role, presents a small UI to select tables to replicate&sync, and automatically configures PowerSync's db connection to Supabase, and configures PoweSync to use Supabase auth when authenticating clients.

This also sets us up for a deeper signed redirect partner integration, which we'll be shipping next!

AI clients shouldnā€™t force you into one model provider. Thunderbolt is an open-source, cross-platform AI client for teams that want to deploy an AI client on-prem. It helps you run an AI client with your own model providers by supporting frontier, local, and on-prem models, while documenting self-hosted backend deployment. Key features: ā€¢ Cross-platform clients ā€“ available for web, iOS, Android, Mac, Linux, and Windows ā€¢ Model choice ā€“ compatible with frontier, local, and on-prem models ā€¢ Bring-your-own provider ā€“ add API keys for OpenAI-compatible providers or use local inference with Ollama or llama.cpp ā€¢ Self-hosting docs ā€“ deployment guidance covers Docker Compose and Kubernetes ā€¢ Local setup path ā€“ Make commands verify tools, install dependencies, start Postgres and PowerSync, and run the app Itā€™s open-source (Mozilla Public License 2.0 license).
