 ## Unreleased
 
-This is a development pre-release.
-
-Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
-
-## v0.1.0
-
-This is a development pre-release.
-
-Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
-
-### Added
-
-### Changed
-- By default, heavy size optimizations are applied.
-
-### Fixed
-
-## 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.

 Ensure that your branch passes `make test` locally when submitting a pull request.

-[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).
+`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).

-1. Create a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly.
-2. If the CI passes, merge the release PR.
-3. Push a tag that has the same `-dev.X` 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 `-dev.X` 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.

-/// 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`.

-# revive-runner
-
-The revive runner is a helper utility aiding in contract debugging.
-
-Given a PVM contract blob, it will upload, deploy and call that contract using a local, stand-alone un-blockchained pallet revive (which is our execution layer).
-
-This is somewhat similar to the geth `evm` utility binary.
-
-## Installation
-
-The `revive-runner` does not depend on the compiler itself, hence installing this utility does not depend on LLVM, so no LLVM build is required.
-
-Inside the root `revive` repository directory, execute:
-
-```bash
-make install-revive-runner
-```
-
-Which will install the `revive-runner` using `cargo`. 
-
-## Usage
-
-Set the `RUST_LOG` environment varibale to the `trace` level to see the full PolkaVM execution trace. For example:
-
-```bash
-RUST_LOG=trace revive-runner -f mycontract.pvm -c a9059cbb000000000000000000000000f24ff3a9cf04c71dbc94d0b566f7a27b94566cac0000000000000000000000000000000000000000000000000000000000000000
