We're here with the next big release for SpacetimeDB, v0.8.0! 🚀🚀🚀
We've merged in more than 70 new PRs since v0.7.3 and we're super excited to share all the new stuff!
As a reminder you can upgrade from v0.7.3 with the spacetime upgrade command. Please note that our ABI has changed with this release and you will therefore need to rebuild your modules.
Highlights
The most impactful changes in this release are:
- New performance metrics tracking for your modules on the Testnet!
- Stability and correctness improvements to the persistent storage.
- Multi-column index support
- Switched to Wasmtime execution engine
- Significant performance improvements
Currently much of our effort is focused around improving performance and stability with the goal of launching the Mainnet in April of next year!
