+### Added
+- Support for solc v0.8.29
+- Decouples the solc JSON-input-output type definitions from the Solidity fronted and expose them via a dedicated crate.
+- `--supported-solc-versions` for `resolc` binary to return a `semver` range of supported `solc` versions.
+- Support for passing LLVM command line options via the prcoess input or providing one or more `--llvm-arg='..'` resolc CLI flag. This allows more fine-grained control over the LLVM backend configuration.
+
+### Changed
+- Storage keys and values are big endian. This was a pre-mature optimization because for the contract itself it this is a no-op and thus not observable. However we should consider the storage layout as part of the contract ABI. The endianness of transient storage values are still kept as-is.
+- Running `resolc` using webkit is no longer supported.
+
+### Fixed
+- A missing byte swap for the create2 salt value.

+- The `ir` output selection option for `--standard-json` mode.

 To create a new pre-release:
 
-1. Merge a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly. The release workflow will attempt to build and publish a new release whenever the latest git tag does not match the cargo package version.
-2. Wait for the `Release` workflow to finish. If the workflow fails after the `build-linux-all` step, check if a tag has been created and delete it before restarting or pushing updates. Note: It's more convenient to debug the release workflow in a fork (the fork has to be under the `paritytech` org to access `parity-large` runners).
-3. Check draft release on [Releases page](https://github.com/paritytech/revive/releases) and publish (should contain `resolc.js`, `resolc.wasm`, `resolc-web.js`, and `resolc-static-linux` release assets)
