 This is a development pre-release.

+
+## v0.4.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Added
+- Line debug information per YUL builtin and for `if` statements.
+- Column numbers in debug information.
+- Support for the YUL optimizer details in the standard json input definition.
+- The `revive-explorer` compiler utility.
+- `revive-yul`: The AST visitor interface.
+
+### Fixed
+- The debug info source file matches the YUL path in `--debug-output-dir`, allowing tools to display the source line. 
+
+## v0.3.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Fixed
+
+- llvm-context: Bugfix the SAR YUL builtin translation.
+- runtime-api: Add the missing `memset` builtin.
+- npm package: Bugfix the exports field defined in the `package.json`.
+
+
+## v0.2.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Changed
+
+- Removed the license printer from the `resolc` binary.
+- EVM bytecode is no longer requested from solc (except in test utils) leading to less compilation work in the pipeline.
+
+### Fixed
+
+- solc-json-interface: Serializing of any custom key in the JSON input is only skipped if not provided.
+- npm package resolution no longer fails with an 'ERR_PACKAGE_PATH_NOT_EXPORTED' error for packages defining exports fields in the `package.json`.
+
+## v0.1.0
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+### Added
+
+- Add the PolkaVM heap size, stack size and debug info CLI compiler options to the standard JSON settings. This makes the standard JSON input succint for reproducible builds.
+
+### Changed
+
+- Supported `polkadot-sdk` version is now `2503.0.1`
+- The `emsdk` version is now `4.0.9`
+
+### Fixed
+
+## v0.1.0-dev.16
+
+This is a development pre-release.
+
 Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
 
+### Added
+
+- Move the npm package from paritytech/js-revive, into this repo. The package `@parity/resolc` will be deployed to npm for each release.
+- Support for solc v0.8.30
+
+### Changed
+
+- By default, heavy size optimizations are applied.
+
+### Fixed
+
+- @parity/resolc: The solc dependency package is constrained to the latest supported version, preventing breaking the package ever time a new solc package was released. 
+- The resolc npm package no longer ignores the optimizer settings
+
+## v0.1.0-dev.14
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
+
+### Added
+
+- The `revive-runner` helper utility binary which helps to run contracts locally without a blockchain node.
+- Allow configuration of the EVM heap memory size and stack size via CLI flags and JSON input settings.
+
+### Changed
+
+- The default PVM stack memory size was increased from 16kb to 32kb.
+
+### Fixed
+
+- Constructors avoid storing zero sized immutable data on exit.
+
+## v0.1.0-dev.13
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
+
+### 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.

 ## Installation
-Please consult [the documentation](https://contracts.polkadot.io/revive_compiler/installation) for installation instructions.
+Building Solidity contracts for PolkaVM requires installing the following two compilers:
+- `resolc`: The revive Solidity compiler YUL frontend and PolkaVM code generator (provided by this repository).
+- `solc`: The [Ethereum Solidity reference compiler](https://github.com/ethereum/solidity/) implemenation.`resolc` uses `solc` during the compilation process, please refer to the [Ethereum Solidity documentation](https://docs.soliditylang.org/en/latest/installing-solidity.html) for installation instructions.
+
+### `resolc` binary releases
+`resolc` is distributed as a standalone binary (with `solc` as the only external dependency). Please download one of our [binary releases](https://github.com/paritytech/revive/releases) for your target platform and mind the platform specific instructions below.

 To create a new pre-release:
 
-1. Create a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly. Add the `release-test` label to trigger the release workflows.
-2. If the CI passes, merge the release PR. The release workflow will attempt to build and publish a new release whenever the latest git tag does not match the cargo package version.
-3. 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).
-4. 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)
-5. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly
+1. Create a release PR which, if necessary:
+  - Updates the versions in the workspace `Cargo.toml`
+  - Updates the version in each crate `Cargo.toml`
+  - Updates the version of the NPM package in `js/resolc/package.json`
+  - Updates the `CHANGELOG.md` to reflect all observable changes
+2. If the CI passes, merge the release PR.
+3. Push a `vX.Y.Z` tag that has the same version as in `Cargo.toml`
+4. The release workflow will attempt to build and publish a new pre-release if the latest tag does match the cargo package version.
+5. Wait for the `Release` workflow to finish. It should create the pre-release with the same name.
+6. Check that pre-release was created on the [Releases page](https://github.com/paritytech/revive/releases) with all artifacts.
+7. After the release is published, another workflow should start automatically and update json files in https://github.com/paritytech/resolc-bin. Check the changes.
