🥇 We're getting close! 🥇

We're full steam ahead toward our 1.0 release soon! This release candidate brings a sneak peek at lots of upcoming changes.

This release will require a data wipe, because we restructured the SpacetimeDB directory structure.

Some highlights:

• Lots of performance improvements!
• Removed the println! and eprintln macros in favor of log::info! and log::error!
• Fix defining multiple tables on the same struct in Rust modules
• CLI
  • Fixed spacetime energy balance not working at all
  • The spacetime dns subcommand is now spacetime rename
  • When updating the cli.toml config file, comments and formatting are preserved
• C#
  • New C# index syntax
  • Reduce noisy C# compilation errors
  • Fixed a bug where C# modules would not build if .NET 9 was installed on the system
