v0.10.0-beta

Yes, the rumors are true - it's release day! 🎉 🎉

We're gearing up for our big 1.0 release later this year, so this release has some great foundational API improvements, improves consistency across ours APIs, and adds some other fantastic foundational features!

Highlights

• Bumped to Rust 1.78
• We now regularly capture a snapshot of the database state, and restore from it when restarting the Database
• Tables are now private by default, and must be explicitly marked as public via #[spacetimedb(table(public))] or [SpacetimeDB.Table(Public = true)]
• Our SDKs now have consistent filter_by_* functions that return a collection of results, and find_by_* functions that return a single result
• Implement a new rand api which fixes bugs in our previous random number generator
• Bugfix: When the database is restarted, we properly treat all clients as disconnected

Big ones!

• Module hotswapping - You can now update your server logic with a new module without disconnecting existing clients! Players will keep on playing and clients will keep on clienting without being any the wiser!
• Recv-style ABI - We've improved the performance of passing data into your module from the host substantially by eliminating several allocations and copies.

CLI changes

• spacetime build uses the --project-path param instead of an anonymous param
• spacetime publish -c requires confirmation (can be overridden with --force)
• spacetime logs -f does not start from the very beginning
