You can view the +[full Bevy 0.2 announcement here][bevy-0-2]. Here are some highlights: + +- Async Task System: Bevy now has a brand new async-friendly task system, + which enables the creation of context-specific task pools. For example, you might + have separate pools for compute, IO, networking, etc. This also provides the + flexibility to load balance work appropriately according to work type and/or priority. + This new task system completely replaces Rayon and the cpu usage wins were huge! +- Initial Web Platform Support: (A subset of) Bevy now runs on the web using + WebAssembly/WASM! Specifically, Bevy apps can run Bevy ECS schedules, react to + input events, create an empty canvas (using winit), and a few other things. This + is a huge first step, but it is important to call out that there are still a + number of missing pieces, such as 2D/3D rendering, multi-threading, and sound. +- Parallel Queries: Systems that use queries already run in parallel, + but before this change the queries themselves could not be iterated in parallel. + Bevy 0.2 adds the ability to easily iterate queries in parallel, which builds on + top of the new Async Task System. +- Transform System Rewrite: Bevy's old transform system used separate + `Translation`, `Rotation`, and `Scale` components as the "source of truth", + which were then synced to a `LocalTransform` component after each update. There + are Good Reasons™ to use this approach, but it created a "lag" between the + calculated LocalTransform and the source components and dataflow between components + is hard to reason about. This problem was resolved by making a newer, simpler + transform system that uses a consolidated `Transform` type. +- Joystick/Gamepad Input: The Bevy Input plugin now has cross-platform support + for most controllers thanks to the gilrs library! +- Bevy ECS Performance Improvements: generational entity IDs, + read-only queries, lock-free world APIs, direct component lookup. + +Community plugin updates: + +- [bevy_rapier](https://github.com/dimforge/bevy_rapier): + Rapier Physics' official Bevy plugin was updated to support Bevy 0.2. +- [bevy_ninepatch](https://crates.io/crates/bevy_ninepatch): + Display 9-Patch UI elements, where you can specify how + different parts of a PNG should grow. +- [bevy_mod_picking](https://github.com/aevyrie/bevy_mod_picking): 3d cursor + picking and highlighting. +- [bevy_contrib_colors](https://crates.io/crates/bevy_contrib_colors): + A simple color library. +- [bevy_input_map](https://crates.io/crates/bevy_prototype_input_map): + Converts user inputs from different input hardware into game specific actions. + Ex: keyboard "Space" or joystick "A" can be mapped to a "Jump" Action. +- [bevy_prototype_lyon](https://github.com/Nilirad/bevy_prototype_lyon): + Draw 2D shapes, like triangles, circles, and beziers. +- [bevy_contrib_inspector](https://github.com/jakobhellermann/bevy-contrib-inspector): + Visually edit fields of your bevy resources in a browser or native view. + +_Discussions: +[/r/rust](https://reddit.com/r/rust/comments/iw1yyp/bevy_02), +[hacker news](https://news.ycombinator.com/item?id=24530698), +[twitter](https://twitter.com/cart_cart/status/1307445918535315456)_ + +[bevy]: https://bevyengine.org +[bevy-repo]: https://github.com/bevyengine/bevy +[bevy-0-2]: https://bevyengine.org/news/bevy-0-2 +[bevy-sponsors]: https://github.com/sponsors/cart + ### [rg3d][rg3d] [][rg3d_twitter]
