+
+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`

+- 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.

-`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).

+/// 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;
+///
