v0.2.3 Geneva (#1256)

### Added - The Solana units `sol` and `lamports` are now supported, e.g. `10 sol` and `100 lamports`. [seanyoung](https://github.com/seanyoung) - User defined operators are now supported. This is a feature in Ethereum Solidity v0.8.19. [seanyoung](https://github.com/seanyoung) - **Solana**: if a contract uses the `SystemAccount`, `ClockAccount`, or other standard builtin accounts, then this is automatically added to the IDL. [LucasSte](https://github.com/LucasSte) - **Substrate**: The content of the debug buffer is formatted in a human readable way. This vastly improves it's readability, allowing to spot API runtime return codes, runtime errors and debug prints much easier. [salaheldinsoliman](https://github.com/salaheldinsoliman) ### Fixed - Solana: contracts with a seed for the constructor do not require a signer in the Anchor IDL [seanyoung](https://github.com/seanyoung) - Fix panic when lexing ".9" at the beginning of a file. [seanyoung](https://github.com/seanyoung) - Forbid ABI encoding and decoding of recursive types. [xermicus](https://github.com/xermicus) - Treat enums as 8bit uint in constant hashing. [xermicus](https://github.com/xermicus) - Fix compilation failure with -g for the substrate target. [salaheldinsoliman](https://github.com/salaheldinsoliman) - Fixed incorrect ABI encoding for user defined types. [xermicus](https://github.com/xermicus) [seanyoung](https://github.com/seanyoung) - Fixed incorrect ABI encoding for struct with fields of type `bytesN` [xermicus](https://github.com/xermicus) - Fixed incorrect handling of recursive struct fields. [xermicus](https://github.com/xermicus) - Fixed a bug in our Common Subexpression Elimination optimization pass [LucasSte](https://github.com/LucasSte) ### Changed - Math overflow is now always enabled, unless the math happens with an `unchecked { .. }` block. The `--math-overflow` command line option has been removed. [seanyoung](https://github.com/seanyoung) - **Substrate**: the SCALE encoder and decoder now uses a much better implementation written in our CFG intermediate format. [xermicus](https://github.com/xermicus) - **Substrate**: When instantiating a new contract without providing a salt, the salt we be derived from the output of the new `instantiation_nonce` runtime API. [xermicus](https://github.com/xermicus) - Minimal Supported Rust Version is `1.65.0` - No longer silently overwrite contract artifacts, if the same contract is defined more than once in different locations [seanyoung](https://github.com/seanyoung) Signed-off-by: Sean Young <[email protected]>
