CHANGELOG.md

@@ -1,3 +1,106 @@
+# Version 1.14.0
+
+- Bump MSRV to 1.65. (#146)
+- Fix docs.rs build. (#152)
+- Upstreaming parts of the Hermit `no_std` patchset:
+  - Use `Self` where possible (#155)
+  - Import items from `core` and `alloc` if possible (#160)
+
+# Version 1.13.3
+
+- Avoid places where the code had a possibility to block or panic. (#147)
+
+# Version 1.13.2
+
+- Fix build failure with minimal-versions. (#132)
+- Prevent executor from becoming unusable by panic of the iterator passed by the user to the `spawn_many`. (#136)
+- Reduce memory footprint. (#137)
+
+# Version 1.13.1
+
+- Fix docs.rs build. (#125)
+
+# Version 1.13.0
+
+- Relax the `Send` bound on `LocalExecutor::spawn_many`. (#120)
+- Ensure all features are documented on `docs.rs`. (#122)
+
+# Version 1.12.0
+
+- Add static executors, which are an optimization over executors that are kept
+  around forever. (#112)
+
+# Version 1.11.0
+
+- Re-export the `async_task::FallibleTask` primitive. (#113)
+- Support racy initialization of the executor state. This should allow the executor to be
+  initialized on web targets without any issues. (#108)
+
+# Version 1.10.0
+
+- Add a function `spawn_batch` that allows users to spawn multiple tasks while only locking the executor once. (#92)
+
+# Version 1.9.1
+
+- Remove the thread-local optimization due to the bugs that it introduces. (#106)
+
+# Version 1.9.0
+
+- Re-introduce the thread-local task push optimization to the executor. (#93)
+- Bump `async-task` to v4.4.0. (#90)
+- Replace some unnecessary atomic operations with non-atomic operations. (#94)
+- Use weaker atomic orderings for notifications. (#95)
+- When spawning a future, avoid looking up the ID to assign to that future twice. (#96)
+
+# Version 1.8.0
+
+- When spawned tasks panic, the panic is caught and then surfaced in the spawned
+ `Task`. Previously, the panic would be surfaced in `tick()` or `run()`. (#78)
+
+# Version 1.7.2
+
+- Fix compilation under WebAssembly targets (#77).
+
+# Version 1.7.1
+
+- Fix compilation under WebAssembly targets (#75).
+- Add a disclaimer indicating that this is a reference executor (#74).
+
+# Version 1.7.0
+
+- Bump `async-lock` and `futures-lite` to their latest versions. (#70)
+
+# Version 1.6.0
+
+- Remove the thread-local queue optimization, as it caused a number of bugs in production use cases. (#61)
+
+# Version 1.5.4
+
+- Fix a panic that could happen when two concurrent `run()` calls are made and the thread local task slot is left as `None`. (#55)
+
+# Version 1.5.3
+
+- Fix an accidental breaking change in v1.5.2, where `ex.run()` was no longer `Send`. (#50)
+- Remove the unused `memchr` dependency. (#51)
+
+# Version 1.5.2
+
+- Add thread-local task queue optimizations, allowing new tasks to avoid using the global queue. (#37)
+- Update `fastrand` to v2. (#45)
+
+# Version 1.5.1
+
+- Implement a better form of debug output for Executor and LocalExecutor. (#33)
+
+# Version 1.5.0
+
+- Remove the dependency on the `once_cell` crate to restore the MSRV. (#29)
+- Update `concurrent-queue` to v2.
+
+# Version 1.4.1
+
+- Remove dependency on deprecated `vec-arena`. (#23)
+
 # Version 1.4.0
 
 - Add `Executor::is_empty()` and `LocalExecutor::is_empty()`.
