+# Changelog
+
+## Unreleased
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `2503.0.1`
+
+## 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`).
+
+### Fixed
+
+## v0.1.0-dev.11
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `274a781e8ca1a9432c7ec87593bd93214abbff50`
+
+### Added
+
+### Changed
+
+### Fixed
+
+- A bug causing incorrect loads from the emulated EVM linear memory.
+- A missing integer truncate after switching to 64bit.
+
+## v0.1.0-dev.10
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev: `274a781e8ca1a9432c7ec87593bd93214abbff50`
+
+### Added
+
+- Support for the `coinbase` opcode.
+- The resolc web JS version.
+
+### Changed
+
+- Missing the `--overwrite` flag emits an error instead of a warning.
+- The `resolc` executable prints the help by default.
+- Removed support for legacy EVM assembly (EVMLA) translation.
+- integration: identify cached code blobs on source code to fix potential confusions.
+- Setting base, include or allow paths in emscripten is now a hard error.
+- Employ a heuristic to detect `address.transfer` and `address.send` calls.
+  If detected, the re-entrant call flag is not set and 0 deposit limit is endowed.
+
+### Fixed
+
+- Solidity: Add the solc `--libraries` files to sources.
+- A data race in tests.
+- Fix `broken pipe` errors.
+- llvm-builder: Allow warnings.
+- solidity: Fix the custom compiler warning messages.
+
+## v0.1.0-dev.9
+
+This is a development pre-release.
+
+### Added
+
+### Changed
+
+- Syscalls with more than 6 arguments now pack them into registers.
+
+### Fixed
+
+- Remove reloading of the resolc.js file (fix issue with relative path in web worker)
+
+## v0.1.0-dev.8
+
+This is a development pre-release.
+
+### Added
+
+- The `revive-llvm-builder` crate with the `revive-llvm` helper utility for streamlined management of the LLVM framework dependency.
+- Initial support for running `resolc` in the browser.
+
+### Changed
+
+- Suported contracts runtime is polkadot-sdk git version `d62a90c8c729acd98c7e9a5cab9803b8b211ffc5`.
+- The minimum supported Rust version is `1.81.0`.
+- Error out early instead of invoking `solc` with invalid base or include path flags.
+
+### Fixed
+
+- Decouple the LLVM target dependency from the LLVM host dependency.
+- Do not error out if no files and no errors were produced. This aligns resolc closer to solc.
+- Fixes input normalization in the Wasm version.
+
+## v0.1.0-dev.7
+
+This is a development pre-release.
+
+### Added
+
+- Implement the `GASPRICE` opcode.
+- Implement the `BASEFEE` opcode.
+- Implement the `GASLIMIT` opcode.
+
+### Changed
+
+- The `GAS` opcode now returns the remaining `ref_time`.
+- Contracts can now be supplied call data input of arbitrary size.
+- Some syscalls now return the value in a register, slightly improving emitted contract code.
+- Calls forward maximum weight limits instead of 0, anticipating a change in polkadot-sdk where weight limits of 0 no longer interprets as uncapped limit.
+
+### Fixed
+
+- A linker bug which was preventing certain contracts from linking with the PVM linker.
+- JS: Fix encoding conversion from JS string (UTF-16) to UTF-8.
+- The git commit hash slug is always displayed in the version string.
+
+## v0.1.0-dev.6
+
+This is a development pre-release.
+
+# Added
+
+- Implement the `BLOCKHASH` opcode.
+- Implement delegate calls.
+- Implement the `GASPRICE` opcode. Currently hard-coded to return `1`.
+- The ELF shared object contract artifact is dumped into the debug output directory.
+- Initial support for emitting debug info (opt in via the `-g` flag)
+
+# Changed
+
+- resolc now emits 64bit PolkaVM blobs, reducing contract code size and execution time.
+- The RISC-V bit-manipulation target feature (`zbb`) is enabled.
+
+# Fixed
+
+- Compilation to Wasm (for usage in node and web browsers)
+
+## v0.1.0-dev.5
+
+This is development pre-release.
+
+# Added
+
+- Implement the `CODESIZE` and `EXTCODESIZE` opcodes.
+
+# Changed
+
+- Include the full revive version in the contract metadata.
+
+# Fixed
+
+## v0.1.0-dev-4
+
+This is development pre-release.
+
+# Added
+
+- Support the `ORIGIN` opcode.
+
+# Changed
+
+- Update polkavm to `v0.14.0`.
+- Enable the `a`, `fast-unaligned-access` and `xtheadcondmov` LLVM target features, decreasing the code size for some contracts.
+
+# Fixed

+
+# revive
+
+YUL recompiler to LLVM, targetting RISC-V on [PolkaVM](https://github.com/koute/polkavm).
+
+Visit [contracts.polkadot.io](https://contracts.polkadot.io) to learn more about contracts on Polkadot!
+
+## Status
+
+This is experimental software in active development and not ready just yet for production usage. Please do report any compiler related issues or missing features that are [not yet known to us](https://contracts.polkadot.io/known_issues/) here.
+
+Discussion around the development is hosted on the [Polkadot Forum](https://forum.polkadot.network/t/contracts-update-solidity-on-polkavm/6949#a-new-solidity-compiler-1).
+
+## Installation
+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
+> xattr -rc resolc-universal-apple-darwin
+> chmod +x resolc-universal-apple-darwin
+> ```
+
+</details>
+
+<details>
+  <summary>Linux users</summary>
+
+> **Linux** users need to set the executable flag.
+> ```sh
+> chmod +x resolc-x86_64-unknown-linux-musl
+> ```
+
+</details>
+
+
+### `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.
+
+## Building from source
+
+Building revive requires a [stable Rust installation](https://rustup.rs/) and a C++ toolchain for building [LLVM](https://github.com/llvm/llvm-project) on your system.
+
+### LLVM
+
+`revive` depends on a custom build of LLVM `v18.1.8` with the RISC-V _embedded_ target, including the `compiler-rt` builtins. You can either download a build from our releases (recommended for older hardware) or build it from source.
+
+<details>
+  <summary>Download from our LLVM releases</summary>
+
+Download the [latest LLVM build](https://github.com/paritytech/revive/releases?q=LLVM+binaries+release&expanded=true) from our releases.
+
+> **MacOS** users need to clear the `downloaded` attribute from all binaries after extracting the archive:
+> ```sh
+> xattr -rc </path/to/the/extracted/archive>/target-llvm/gnu/target-final/bin/*
+> ```
+
+After extracting the archive, point `$LLVM_SYS_181_PREFIX` to it:
+```sh
+export LLVM_SYS_181_PREFIX=</path/to/the/extracted/archive>/target-llvm/gnu/target-final
+```
+
+</details>
+
+<details>
+  <summary>Building from source</summary>
+
+ Use the provided [revive-llvm](crates/llvm-builder/README.md) utility to compile a compatible LLVM build locally and point `$LLVM_SYS_181_PREFIX` to the installation afterwards.
+
+The `Makefile` provides a shortcut target to obtain a compatible LLVM build:
+
+```sh
+make install-llvm
+export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final
+```
+
+</details>
+
+### The `resolc` Solidity frontend
+
+To build the `resolc` Solidity frontend executable, make sure you have obtained a compatible LLVM build and did export the `LLVM_SYS_181_PREFIX` environment variable pointing to it (see [above](#LLVM)).
+
+To install the `resolc` Solidity frontend executable:
+
+```sh
+make install-bin
+resolc --version
+```
+
+### Cross-compilation to Wasm
+
+Cross-compile the `resolc.js` frontend executable to Wasm for running it in a Node.js or browser environment. The `REVIVE_LLVM_TARGET_PREFIX` environment variable is used to control the target environment LLVM dependency.
+
+<details>
+  <summary>Instructions for cross-compilation to wasm32-unknown-emscripten</summary>
+
+```sh
+# Build the host LLVM dependency with PolkaVM target support
+make install-llvm
+export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final
+
+# Build the target LLVM dependency with PolkaVM target support
+revive-llvm --target-env emscripten clone
+source emsdk/emsdk_env.sh
+revive-llvm --target-env emscripten build --llvm-projects lld
+export REVIVE_LLVM_TARGET_PREFIX=${PWD}/target-llvm/emscripten/target-final
+
+# Build the resolc frontend executable
+make install-wasm
+make test-wasm
+```
+
+</details>
+
+## Development
+
+Please consult the [Makefile](Makefile) targets to learn how to run tests and benchmarks. 
+Ensure that your branch passes `make test` locally when submitting a pull request.
+
+### Design overview
+See the [relevant section in our documentation](https://contracts.polkadot.io/revive_compiler/architecture) to learn more about how the compiler works. 
+
+### Tests
+
+Before running the tests, ensure that Geth (Go Ethereum) is installed on your system. Follow the installation guide here: [Installing Geth](https://geth.ethereum.org/docs/getting-started/installing-geth).
+Once Geth is installed, you can run the tests using the following command:
+
+```sh
+make test
+```
+# Acknowledgements
+
+The revive compiler project, after some early experiments with EVM bytecode translations, decided to fork the `era-compiler` framework.
+[Frontend](https://github.com/matter-labs/era-compiler-solidity), [code generator](https://github.com/matter-labs/era-compiler-llvm-context) and some supporting libraries are based of ZKSync `zksolc`. I'd like to express my gratitude and thank the original authors for providing a useable code base under a generous license.

+# Release checklist
+
+Prior to the first stable release we neither have formal release processes nor do we follow a fixed release schedule.
+
+To create a new pre-release:
+
+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.
+8. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly
+
+# `resolc` NPM package release
+
+Will happen automatically.
+
+# LLVM release
+
+To create a new LLVM release, run "Release LLVM" workflow. Use current LLVM version as parameter, e.g. `18.1.8`.
+Version suffix will be resolved automatically.  
+The workflows will create new GitHub release, and upload LLVM binaries.
+Next release of resolc will use newly created binaries.
