SpacetimeDB Files

We have another release for you! :tada:

This one is quiet as far as new features go (stay tuned for those soon), but we're including a ton of performance improvements in both server code and generated client code. We've also fixed several important bugs, and made some quality of life improvements for generated code.

A few particular things that people have been asking about: - We now use import type properly in generated TypeScript code - Fixed Equals and GetHashCode for types containing lists and arrays in C# code - Fixed SDK bug with overlapping subscriptions - Fix a bug where spacetime rename would leave the old name in place - Fix a bug where RLS would stop working after opening the web dashboard - Added an unstable HTTP route for getting the current timestamp
