+## 0.0.10 - 2023-12-10
+
+- Fixed handling of crates with multiple binaries. Attempting to strip binaries for such a crate
+  caused the build to fail. Reported by Tomaž Hribernik. GH #8
+- Added a new `cross-version` parameter. This can be specified to make this action use a specific
+  version of `cross`. If this is not specified, the latest version will be used.
+
+## 0.0.9 - 2023-09-10
+
+- Added a `working-directory` parameter. By default this is the current directory (`.`) but you can
+  set it to something else to compile a single crate or workspace in a subdirectory of the repo.
+  This allows you to use this action with monorepos with multiple crates. Based on GH #7 by
+  @aaronvg.
+
+## 0.0.8 - 2023-07-22
+
+- For builds that need the `cross` binary, this binary is now cached. A cache hit saves about 20
+  seconds in my tests. Suggested by @timon-schelling. GH #4.
+
+## 0.0.7 - 2023-04-21
+
+- The toolchain argument was (probably) not being respected with cross builds, though it's hard to
+  be sure since none of the output from past CI runs I've looked at it includes the toolchain
+  version in the output. But now the toolchain version is explicitly passed to all `cargo` and
+  `cross` commands.
+
+## 0.0.6 - 2023-04-21
+
+- When the `strip` parameter was true, stripping binaries could fail if there were both
+  `target/*/debug` and `target/*/release` directories present and the `debug` directory didn't have
+  a binary. Now it will strip all binaries it finds under `target`.
+
+## 0.0.5 - 2023-03-19
+
+- Fix use of `dtolnay/rust-toolchain` action to allow passing a `toolchain` input.
+
+## 0.0.4 - 2023-03-19
+
+- Added a new `toolchain` parameter to allow selecting a Rust toolchain other than stable. This
+  supports picking on of "stable", "beta", or "nightly".
+- Fixed binary stripping to work in more situations. Previously it depended on a very specific setup
+  plus expected to be run in the context of the matrix I use for my own projects.
+- Fixed a reference to a matrix variable that should have referenced an input variable.

 Finally, it will run `strip` to strip the binary if the `strip` parameter is true. This is only
 possible for builds that are not done via `cross`. In addition, Windows builds for `aarch64` cannot
 be stripped either.
