@@ -4,6 +4,48 @@ All notable changes to this project will be documented in this file.
 
 This project adheres to [Semantic Versioning](http://semver.org/).
 
+## 2.1.0
+* The action now caches compilers in your repository's Actions cache by default. This significantly
+  speeds up installs on average. [#53](https://github.com/goto-bus-stop/setup-zig/pull/53)
+
+  2.0.2 also had caching-related changes but they didn't actually do much, based on a misunderstanding
+  of what the `tool-cache` is for.
+
+## 2.0.2
+* Fix tool-cache usage, this should speed up the action if zig was already downloaded before. [#45](https://github.com/goto-bus-stop/setup-zig/pull/45)
+
+## 2.0.1
+* Update docs to v2
+
+## 2.0.0
+* Change `version` option default to `master`. See [#24](https://github.com/goto-bus-stop/setup-zig/issues/24)
+
+## 1.3.0
+* Support pinning to a specific commit of the zig compiler. ([@codehz](https://github.com/codehz) in [#14](https://github.com/goto-bus-stop/setup-zig/pull/14))
+  ```yaml
+  uses: goto-bus-stop/setup-zig@v1
+  with:
+    version: 0.6.0+4b48fccad
+  ```
+* Add tests for the version -> URL resolution code.
+
+## 1.2.5
+* Update dependencies to fix #11.
+
+## 1.2.4
+* Update dependencies simple-get and ncc.
+
+## 1.2.3
+* Configure Actions to build releases automatically.
+
+## 1.2.2
+* Update examples. ([#7](https://github.com/goto-bus-stop/setup-zig/pull/7))
+* Upgrade dependencies.
+* Recommend using @v1 instead of pinning to a version.
+
+## 1.2.1
+* Make `version: master` actually work.
+
 ## 1.2.0
 * Allow setting `version: master` to get the latest build from the development branch.

+This action caches the downloaded compilers in your repository's Actions cache by default,
+to reduce the load on the Zig Foundation's servers. Cached compilers are only about 60MB
