+
+## 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.
+
+## v0.1.0-dev.12
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `21f6f0705e53c15aa2b8a5706b208200447774a9`
+
+### Added
+
+- Per file output selection for `--standard-json` mode.
+- The `ir` output selection option for `--standard-json` mode.
+
+### Changed
+
+- Improved code size: Large contracts compile to smaller code blobs when enabling aggressive size optimizations (`-Oz`).

 ## 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.
+
+<details>
+  <summary>MacOS users</summary>
+
+> **MacOS** users need to clear the `downloaded` attribute from the binary and set the executable flag.
+> ```sh

+
+
+### `resolc` NPM package
+We distribute the revive compiler as [node.js module](https://www.npmjs.com/package/@parity/resolc) and [hardhat plugin](https://www.npmjs.com/package/@parity/hardhat-polkadot-resolc).
+
+Note: The `solc` dependency is bundled via NPM packaging and defaults to the latest supported version.

 To create a new pre-release:

-4. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly

+/// The Solidity `address.transfer` and `address.send` call detection heuristic.
+///
+/// # Why
+/// This heuristic is an additional security feature to guard against re-entrancy attacks
+/// in case contract authors violate Solidity best practices and use `address.transfer` or
+/// `address.send`.
+/// While contract authors are supposed to never use `address.transfer` or `address.send`,
+/// for a small cost we can be extra defensive about it.
+///
+/// # How
+/// The gas stipend emitted by solc for `transfer` and `send` is not static, thus:
+/// - Dynamically allow re-entrancy only for calls considered not transfer or send.
+/// - Detected balance transfers will supply 0 deposit limit instead of `u256::MAX`.
+///
+/// Calls are considered transfer or send if:
+/// - (Input length | Output lenght) == 0;
+/// - Gas <= 2300;

-/// The Solidity `address.transfer` and `address.send` call detection heuristic.
-///
-/// # Why
-/// This heuristic is an additional security feature to guard against re-entrancy attacks
-/// in case contract authors violate Solidity best practices and use `address.transfer` or
-/// `address.send`.
-/// While contract authors are supposed to never use `address.transfer` or `address.send`,
-/// for a small cost we can be extra defensive about it.
-///
-/// # How
-/// The gas stipend emitted by solc for `transfer` and `send` is not static, thus:
-/// - Dynamically allow re-entrancy only for calls considered not transfer or send.
-/// - Detected balance transfers will supply 0 deposit limit instead of `u256::MAX`.
-///
-/// Calls are considered transfer or send if:
-/// - (Input length | Output lenght) == 0;
-/// - Gas <= 2300;
-///
-/// # Returns
-/// The call flags xlen `IntValue` and the deposit limit word `IntValue`.
