### Added
- Solidity mappings can now have named key and named value types. [seanyoung](https://github.com/seanyoung)
### Changed
- Solang now uses LLVM 15. [LucasSte](https://github.com/LucasSte)
- Solidity on Solana now required the Anchor framework for the client code, and the `@solana/solidity.js`
Typescript library is no longer compatible with Solidity.
- When casting hex literal numbers into the `bytesN` type, the hex literal may use leading zeros to match the size
with the according `bytesN`, which aligns solang with `solc`. [xermicus](https://github.com/xermicus)
### Fixed
- Many bugs have been fixed by [seanyoung](https://github.com/seanyoung), [LucasSte](https://github.com/LucasSte)
and [xermicus](https://github.com/xermicus)
- Typos throughout the code have been fixed. [omahs](https://github.com/omahs)
