What's this? What's this? A release in the air!

This release just adds two small improvements to the timer table functionality from the last release:

  • Bugfix: Dedup schedueler queue (#1587)
  • Add volatile_nonatomic_schedule_immediate (#1612)

Don't be fooled by this tiny release, though - our next release will be a big one! Keep an eye out for the big API improvements and upcoming stability soon! Before you know it, we'll have our big 1.0 release!

We have a big release for you today 🎉 🎉 ! We're including some big performance improvements ⚡ and long-awaited bugfixes 🐞! Remember to stay tuned for our 0.12 release soon.

This release includes some major breaking changes, so you won't be able to use your old databases with this version. Run spacetime local clear to remove them.

Important changes

Major

  • ⚡ We removed our usage of protobuf, in favor of our own internal format (#1077) - this is a big performance improvement on the client and the server!
  • ⌛ We removed the server-side schedule! macro and its equivalents in favor of table-based timers (#1449). Please check our server module docs for more info on how to use the new system.

Here is some example code which uses the new timer tables:

// The `scheduled` attribute links this table to a reducer.
#[spacetimedb(table, scheduled(send_message))]
struct SendMessageTimer {
    text: String,
}

// Reducers linked to the scheduler table should have their first argument as `ReducerContext` 
// and the second as an instance of the table struct it is linked to.
#[spacetimedb(reducer)]
fn send_message(ctx: ReducerContext, arg: SendMessageTimer) -> Result<(), String> {
    // ...
}

// Scheduling reducers inside `init` reducer
fn init() {
    // Scheduling a reducer for a specific Timestamp
    SendMessageTimer::insert(SendMessageTimer {
        scheduled_id: 0,
        text:"bot sending a message".to_string(),
        //`spacetimedb::Timestamp` implements `From` trait to `ScheduleAt::Time`. 
        scheduled_at: ctx.timestamp.plus(Duration::from_secs(10)).into()
    });

    // Scheduling a reducer to be called at fixed interval of 100 milliseconds.
    SendMessageTimer::insert(SendMessageTimer {
        scheduled_id: 0,
        text:"bot sending a message".to_string(),
        //`std::time::Duration` implements `From` trait to `ScheduleAt::Duration`. 
        scheduled_at: duration!(100ms).into(),
    });
}

CLI changes

  • We have a new subscribe subcommand! (#1343)
  • Bugfix: Update help text suggesting spacetime server fingerprint to have the correct -s param (#1457)
  • Bugfix: spacetime server add - Remove trailing /s from server URIs (#1552)

Web API

  • Recovery code APIs are now under /identity and using POST (#1492)
  • /identity GET returns an empty success if the email address is not found (#1491)

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

Yes, we just released 0.9.1 🎉, but we just love releasing the latest and greatest things to the community!

And in this case, the latest and greatest thing is an 🔒 important security patchfix! Private tables are now properly protected.

Thank you to 📣 @Chippy in our Discord server for pointing this out so we were able to fix it quickly!

v0.9.1

Today's a good day - we have a new release for you! It's not the fanciest, shiniest release - but it includes some nice cleanups and important fixes.

As a reminder you can upgrade from the previous release with the spacetime upgrade command.
If you are on macOS and you've installed through brew we recommend using brew install clockworklabs/tap/spacetime to upgrade.

Highlights

🗑️ Removed repeating reducers

⚠️ We have removed repeating reducers (#[spacetimedb(reducer, repeat = _)]) in favor of just using schedule!.

There are a lot of nuances to what exactly "repeating" means. It's easier for everyone to understand code that schedules what it wants, when it wants.

💻 CLI updates

⚠️ The default server is now testnet instead of local!

The meaning of -s and -S are more consistent between CLI commands (-s is for --server, -S is for --skip_clippy). spacetime build, spacetime identity, and spacetime server have been tweaked.

🛠️ Bugfixes

  • Fix select * from *
  • Atomically downgrade lock when committing tx to prevent deadlock
  • fix(1170): Use scope guard to decrement reducer queue length
  • fix(1173): Record wait time for all reducers

v0.9 🚀🚀🚀

We have got a big one for you! Today we are releasing version 0.9 of SpacetimeDB. It's been a while since our last official release and we have got a huge number changes and performance improvements.

Most notably performance has improved by 10x - 100x or more for certain parts of the database! Subscription evaluation in particular has gotten almost 100 times faster! This makes an enormous difference for people shipping production games. 🏃🏃🏃

Version 0.9 is the same version that we ran the Closed Alpha for the MMOPRG BitCraft, which had 700 players playing concurrently in a single database! We are battle testing SpacetimeDB with our production game!

We're so excited to see what people build with this new version!

As a reminder you can upgrade from the previous release with the spacetime upgrade command. If you are on macOS and you've installed through brew we recommend using brew install clockworklabs/tap/spacetime to upgrade.

Highlights

  • Vastly improved metrics gathering performance overhead
  • Stabilized new transaction log format for a 2-3x reduction in transaction log size and much faster reply times
  • Reduced unnecessary copying and cloning in core database paths
  • Improved threading model for optimal performance
  • Fixed a critical issue for misbehaving clients or clients with very poor latency
  • Multi-column index selection for the query! macro
  • Huge number of critical performance and bug fixes!

v0.8.2-beta

Our release 0.8.2 is available now! It includes tons of performance improvements and some great bugfixes!

As a reminder you can upgrade from the previous release with the spacetime upgrade command. If you are on macOS and you've installed through brew we recommend using brew install clockworklabs/tap/spacetime to upgrade.

Highlights

  • Memory architecture refactor: we're working on rearchitecting the way we store and retrieve data from the database. This is our first batch of improvements which reduces the amount of overhead when reading values from the database. This affects both subscription query performance and module performance.
  • Tons of performance improvements
    • Incremental subscription queries are now evaluated in parallel
    • Join evaluation performance improvements
    • Lookups on an indexed column are faster
  • Fixed spacetime generate --delete-files works properly without using --force
  • Bug fixes
    • Fixed correctness issues with subscription queries
    • Fixed some issues related to unwrapping on None

v0.8.1-beta

Our release 0.8.1 is available now! This minor release is the first release of the year for us and we're excited to show you all what we've been working on recently 🎉

As a reminder you can upgrade from the previous release with the spacetime upgrade command. If you are on macOS and you've installed through brew we recommend using brew install clockworklabs/tap/spacetime to upgrade.

Highlights

  • Remote server URL is printed during spacetime publish
  • Testnet has been added to the default spacetime CLI config
  • spacetime local clear allows you to clear your local database without deleting the entire ~/.spacetime/ directory
  • spacetime generate --delete-files ... will also delete any files generated by SpacetimeDB that are no longer needed
  • Output directory used by spacetime generate creates the directory if it doesn't already exist
  • Subscription query performance optimizations
  • spacetime logs ... now prints to stdout instead of stderr

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!
