SpacetimeDB version history

- TypeScript optional fields now use optional key syntax (breaking change for some users). - Fixed regression in `Identity` and `ConnectionId` propagation in procedures. - `spacetime init --template` now lists available templates when no argument is provided.

2.6.0 adds Primary Key support for Views in Rust, TypeScript, and C#, improves event table automigrations, includes CLI binary distribution improvements, and brings various performance enhancements and bug fixes. ## Features ### Primary Key support for Views (Rust, TypeScript, and C#) Procedural views now support primary keys in Rust, TypeScript, and C# > **Note:** C++ support for primary keys in views will be added in a future release. - **Rust**: Declare primary keys in the `#[view]` macro: ```rust #[spacetimedb::view(accessor = my_players, public, primary_key = id)] pub fn my_players(ctx: &spacetimedb::ViewContext) -> Vec<Player> { ctx.db.players().owner().filter(ctx.sender()).collect() } ``` ([#5111](https://github.com/clockworklabs/SpacetimeDB/pull/5111)) - **TypeScript**: Declare primary keys at the column/row level: ```typescript const Player = t.row('Player', { id: t.u64().primaryKey(), owner: t.identity().index('btree'), name: t.string(), }); export const my_players = spacetimedb.view( { public: true }, t.array(players.rowType), ctx => Array.from(ctx.db.players.owner.filter(ctx.sender))

2.5.0 graduates procedures to stable availability, improves billing metric accuracy, and includes CLI usability fixes. --- ### Features #### **Procedures are now stable** (Ungated from `unstable`) Procedures-scheduled, transaction-capable server-side functions-and the outgoing HTTP client (`ctx.http`) are now available without opting into unstable features ([#5164](https://github.com/clockworklabs/SpacetimeDB/pull/5164)). - **Rust**: The `#[spacetimedb::procedure]` macro, `ProcedureContext`, `with_tx`/`try_with_tx`, and scheduled procedures now work without `features = ["unstable"]`. - **C#**: `[Experimental("STDB_UNSTABLE")]` removed from `ProcedureContext.WithTx/TryWithTx`. - **C++**: Procedure ABI, transaction execution, and outgoing HTTP client are now available without `SPACETIMEDB_UNSTABLE_FEATURES`. HTTP handlers/webhooks, views, and RLS (`client_visibility_filter`) remain gated behind unstable. #### **Primary key support for procedural views (C#)** Following Rust and TypeScript support in v2.4.1, C# modules can now declare primary keys on procedural views, enabling clients to receive `OnUpdate` events when subscribed to them ([#5246](https://github.com

We are releasing two small patches on top of 2.4.0: [(#5111) Add primary key support for procedural views to rust and ts modules](https://github.com/clockworklabs/SpacetimeDB/pull/5111) > Adds support for primary keys to procedural views in rust and typescript modules. Now clients can receive update events when subscribed to such views. [(#5145) Fix index schema from st tables.](<https://github.com/clockworklabs/SpacetimeDB/pull/5145>) This fixes https://github.com/clockworklabs/SpacetimeDB/issues/4701. More to come soon! **Full Changelog**: https://github.com/clockworklabs/SpacetimeDB/compare/v2.4.0...v2.4.1

2.4.0 brings a headline new capability for Rust modules HTTP handlers alongside meaningful improvements to runtime performance, durability correctness, and server-side observability. The changelog is focused but every entry is production-relevant. ## Features ### HTTP handlers in modules This is currently an `unstable` feature and will need to be enabled to have be available. * Rust users can enable `unstable` features in their `Cargo.toml`: ```rust [dependencies] spacetimedb = { version = "1.*", features = ["unstable"] } ``` * C# users can enable `unstable` features by adding `#pragma warning disable STDB_UNSTABLE` at the top of your file. * C++ users can enable `unstable` features by adding `#define SPACETIMEDB_UNSTABLE_FEATURES` before including the SpacetimeDB header. Modules can now define custom HTTP routes and serve arbitrary HTTP requests directly from module code (Rust: [#4636](https://github.com/clockworklabs/SpacetimeDB/pull/4636), Typescript: [#4980](https://github.com/clockworklabs/SpacetimeDB/pull/4980), C#: [#5024](https://github.com/clockworklabs/SpacetimeDB/pull/5024),C++: [#5023](https://github.com/clockworklabs/SpacetimeDB/pull/5023)).

This release brings first-party Godot support and major WebSocket performance improvements. We've also landed significant pipeline optimizations, commitlog enhancements, and expanded our framework coverage. ## Features ### First-party Godot SDK and Blackholio Tutorial SpacetimeDB now officially supports Godot with a complete C# SDK integration. The new Blackholio tutorial walks through building a multiplayer asteroids-style game, demonstrating best practices for entity replication, player input handling, and game state management in Godot (#4920). ### Faster WebSocket Transport with Batched Responses The WebSocket layer now pipelines and batches responses using the v3 protocol, significantly reducing per-message overhead under high load. Combined with pipelined JavaScript module operations (#4962), WASM module operations (#4973), and a fully pipelined WebSocket send path (#5051), this delivers substantially improved throughput for real-time applications. ### HTTP/2 Backend Support The SpacetimeDB server now supports HTTP/2, enabling more efficient client connections with multiplexed streams and header compression (#5027). ### Vue `useProcedure` Hook Following the

2.2.0 is here, and this one is a meaningful step forward for SpacetimeDB's realtime performance, operational safety, and day-to-day developer workflow. There are plenty of smaller fixes in this release too, but these are the major changes worth calling out. ## Features ### Faster realtime transport and client throughput We’ve introduced a new v3 WebSocket transport that batches multiple logical client messages into a single frame, cutting per-message overhead while keeping the existing message model intact (#4761). The TypeScript SDK now uses the new transport by default (#4784). Under the hood, this release also includes a substantial round of hot-path performance work across the TS client, JS module runtime, and durability pipeline to improve throughput and reduce scheduler overhead under load. ### Safer production database operations We added `spacetime lock` and `spacetime unlock` to protect databases from accidental deletion (#4502). On top of that, `spacetime delete` now asks for confirmation by default (#4770), `spacetime list` shows database names alongside identities (#4769), and `spacetime publish --yes` can now skip only the prompts you intend to skip instead of ski

Another week, another reason to celebrate 🎉 2.1.0 is here, and it's bringing some long-awaited features alongside a handful of satisfying bug squashes! ## Features ### 🦀 Rust client Wasm support This one's been a long time coming. The Rust client SDK can now compile and run in the browser thanks to resolved Wasm compilation issues. If you've been waiting to build browser-based apps with the Rust SDK, your wait is over https://github.com/clockworklabs/SpacetimeDB/pull/4183 ### 🎮 C++ Modules + Unreal SDK Unreal developers, rejoice — both the C++ module bindings and the Unreal SDK have been brought up to speed with SpacetimeDB 2.0's APIs and codegen. Full compatibility, no more workarounds. - Update C++ bindings for 2.0 compatibility <https://github.com/clockworklabs/SpacetimeDB/pull/4461> - Update Unreal SDK to match latest APIs and codegen <https://github.com/clockworklabs/SpacetimeDB/pull/4497> ## Bug Fixes There are several bug fixes in this release: * Fix useTable isReady reverting to false after first row event by https://github.com/clockworklabs/SpacetimeDB/pull/4580 * Fix v2 client disconnects dropping subscriptions for other v2 clients https://gith
