+# Changelog
+
+## Unreleased
+
+## 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

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          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
+          include a readable copy of the attribution notices contained
+          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
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          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
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      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

+      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 and EVM assembly 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
+
+`resolc` depends on the [solc](https://github.com/ethereum/solidity) binary installed on your system.
+
+Building from source requires a compatible LLVM build.
+
+### LLVM
+
+`revive` requires a build of LLVM 18.1.4 or later with the RISC-V _embedded_ target, including `compiler-rt`. Use the provided [build-llvm.sh](build-llvm.sh) build script to compile a compatible LLVM build locally in `$PWD/llvm18.0` (don't forget to add that to `$PATH` afterwards).
+
+### The `resolc` Solidity frontend
+
+To install the `resolc` Solidity frontend executable:
+
+```bash
+bash build-llvm.sh
+export PATH=${PWD}/llvm18.0/bin:$PATH
+make install-bin
+resolc --version
+```
+### Cross-compilation to WASM
+
+Cross-compiles the Revive compiler to WASM for running it in a Node.js or browser environment.
+
+Install [emscripten](https://emscripten.org/docs/getting_started/downloads.html). Tested on version 3.1.64.
+To build resolc.js execute:
+
+```bash
+bash build-llvm.sh
+export PATH=${PWD}/llvm18.0/bin:$PATH
+export EMSDK_ROOT=<PATH_TO_EMSCRIPTEN_SDK>
+bash emscripten-build-llvm.sh
+source $EMSDK_ROOT/emsdk_env.sh
+export LLVM_LINK_PREFIX=${PWD}/llvm18.0-emscripten
+export PATH=$PATH:$PWD/llvm18.0-emscripten/bin/
+make install-wasm
+```
+
+### 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
+
+`revive` uses [solc](https://github.com/ethereum/solidity/), the Ethereum Solidity compiler, as the [Solidity frontend](crates/solidity/src/lib.rs) to process smart contracts written in Solidity. The YUL IR code (or legacy EVM assembly as a fallback for older `solc` versions) emitted by `solc` is then translated to LLVM IR, targetting [Polkadots `revive` pallet](https://docs.rs/pallet-revive/latest/pallet_revive/trait.SyscallDoc.html).
+[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`.
+
+## 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:
+
+```bash
+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. Merge a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly
+2. Push a release tag to `main`
+3. Manually trigger the `Build revive-debian` action
+4. Create a __pre-release__ from the tag and manually upload the build artifact generated by the action
+5. Manually upload `resolc.js` and `resolc.wasm` from the `build-revive-wasm` action artifacts.
+6. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly

+# Known issues
+
+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.
