+## v0.1.0-dev.6
+
+This is a development pre-release.
+
+# Added

 `revive` requires a build of LLVM 18.1.4 or later 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).

+Cross-compiles the Revive compiler to WASM for running it in a Node.js or browser environment.

+To build resolc.js execute:

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

+## 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.
