+# Changelog
+
+## Unreleased
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
+
+## 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

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# 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
+Please consult [the documentation](https://contracts.polkadot.io/revive_compiler/installation) for installation instructions.
+
+## 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. 
+
+[Frontend](https://github.com/matter-labs/era-compiler-solidity) and [code generator](https://github.com/matter-labs/era-compiler-llvm-context) are based of ZKSync `zksolc` (the project started as a fork of the era compiler).
+
+### 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
+```

+# 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 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
+
+# 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.

+The following is known and we are either working on it or it is a hard limitation. Please do not open a new issue.
+
+## Release
+
+`0.1.0-dev-2`
+
+## Missing features
+
+- [Libraries with public functions are not supported](https://github.com/paritytech/revive/issues/91)
+- [Automatic import resolution is not supported](https://github.com/paritytech/revive/issues/98)
+- The emulated EVM linear contract memory is limited to 64kb in size. Will be fixed with support for metered dynamic memory.
+- [The contract calldata is currently limited to 1kb in size](https://github.com/paritytech/revive/issues/57)
+- [EIP-4844 opcodes are not supported](https://github.com/paritytech/revive/issues/64)
+- [Delegate calls are not supported](https://github.com/paritytech/revive/issues/67)
+- [The `blockhash` opcode is not supported](https://github.com/paritytech/revive/issues/61)
+- [The `extcodesize` opcode is not supported](https://github.com/paritytech/revive/issues/58)
+- [The `origin` opcode is not supported](https://github.com/paritytech/revive/issues/59)
+- [Gas limits for contract calls are ignored](https://github.com/paritytech/revive/issues/60)
+- [Gas related opcodes are not supported](https://github.com/paritytech/revive/issues/60)
+- IPFS metadata hashes are not supported
+- [Compiled contract artifacts can exceed the pallet static memory limit and fail to deploy](https://github.com/paritytech/revive/issues/96).
+- [Transfers to inexistant accounts will fail if the transferred value lies below the ED.](https://github.com/paritytech/revive/issues/83) Will be fixed in the pallet to make the ED completely transparent for contracts.
+
+## Wontfix
+
+Please consult our documentation to learn more about Solidity and EVM features likely to remain unsupported (and why they will not be supported).
+
+TODO: Insert link to the relevant documentation section.

+# revive LLVM builder
+
+Parity fork of the [Matter Labs zksync LLVM builder](https://github.com/matter-labs/era-compiler-llvm-builder) helper utility for compiling [revive](https://github.com/paritytech/revive) compatible LLVM builds.
+
+## Installation and usage
+
+The LLVM compiler framework for revive must be built with our tool called `revive-llvm`.
+This is because the revive compiler has requirements not fullfilled in upstream builds:
+- Special builds for compiling the frontend into statically linked ELF binaries and also Wasm executables
+- The RISC-V target (the PolkaVM target)
+- The compiler-rt builtins for the PolkaVM target
+- We want to leave the assertions always on
+- Various other specific configurations and optimization may be applied
+
+Obtain a compatible build for your host platform from the release section of this repository (TODO). Alternatively follow below steps to get a custom build:
+
+<details>
+<summary>1. Install the system prerequisites.</summary>
+
+   * Linux (Debian):
+
+      Install the following packages:
+      ```shell
+      apt install cmake ninja-build curl git libssl-dev pkg-config clang lld
+      ```
+   * Linux (Arch):
+
+      Install the following packages:
+      ```shell
+      pacman -Syu which cmake ninja curl git pkg-config clang lld
+      ```
+
+   * MacOS:
+
+      * Install the [HomeBrew](https://brew.sh) package manager.
+      * Install the following packages:
+
+         ```shell
+         brew install cmake ninja coreutils
+         ```
+
+      * Install your choice of a recent LLVM/[Clang](https://clang.llvm.org) compiler, e.g. via [Xcode](https://developer.apple.com/xcode/), [Apple’s Command Line Tools](https://developer.apple.com/library/archive/technotes/tn2339/_index.html), or your preferred package manager.
+</details>
+
+<details>
+<summary>2. Install Rust.</summary>
+
+   * Follow the latest [official instructions](https://www.rust-lang.org/tools/install:
+      ```shell
+      curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+      . ${HOME}/.cargo/env
+      ```
+
+      > Currently we are not pinned to any specific version of Rust, so just install the latest stable build for your   platform.
+</details>
+
+<details>
+<summary>3. Install the revive LLVM framework builder.</summary>
+
+   * Install the builder using `cargo`:
+      ```shell
+      cargo install --git https://github.com/paritytech/revive-llvm-builder --force --locked
+      ```
+
+      > The builder is not the LLVM framework itself, but a tool that clones its repository and runs a sequence of build commands. By default it is installed in `~/.cargo/bin/`, which is recommended to be added to your `$PATH`.
+
+</details>
+
+<details>
+<summary>4. (Optional) Create the `LLVM.lock` file.</summary>
+
+   * The `LLVM.lock` dictates the LLVM source tree being used.
+     A default `./LLVM.lock` pointing to the release used for development is already provided.
+
+</details>
+
+<details>
+<summary>5. Build LLVM.</summary>
+
+   * Clone and build the LLVM framework using the `revive-llvm` tool.
+
+     The clang and lld projects are required for the `resolc` Solidity frontend executable; they are enabled by default. LLVM assertions are also enabled by default.
+
+      ```shell
+      revive-llvm clone
+      revive-llvm build --llvm-projects lld --llvm-projects clang
+      ```
+
+      Build artifacts end up in the `./target-llvm/gnu/target-final/` directory by default.
+      The `gnu` directory depends on the supported archticture and will either be `gnu`, `musl` or `emscripten`.
+      You now need to export the final target directory `$LLVM_SYS_181_PREFIX`: `export LLVM_SYS_181_PREFIX=${PWD}/target-llvm/gnu/target-final`
+      If built with the `--enable-tests` option, test tools will be in the `./target-llvm/gnu/build-final/` directory, along with copies of the build artifacts. For all supported build options, run `revive-llvm build --help`.
+
+</details>
+
+## Supported target architectures
+
+The following target platforms are supported:
+- Linux GNU (x86)
+- Linux MUSL (x86)
+- MacOS (aarch64)
+- Windows GNU (x86)
+- Emscripten (wasm32)
+
+<details>
+<summary>Building for MUSL</summary>
+
+   * Via a musl build we can build revive into fully static ELF binaries.
+     Which is desirable for reproducible Solidity contracts builds.
+     The resulting binary is also very portable, akin to the`solc` frontend binary distribution.
+
+     Clone and build the LLVM framework using the `revive-llvm` tool:
+      ```shell
+      revive-llvm --target-env musl clone
+      revive-llvm --target-env musl build --enable-assertions --llvm-projects clang --llvm-projects lld 
+      ```
+
+</details>
+
+<details>
+<summary>Building for Emscripten</summary>
+
+   * Via an emsdk build we can run revive in the browser and on node.js.
+
