+- 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.
+

+### 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

 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.

+# 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
