Solidity Compiler for Solana and Polkadot
This release improves the Solana developer experience, since now required accounts can be specified using annotations. For Polkadot, compatibility with Ethereum Solidity has been increased further, it is now possible to write EIP-1967 compatible proxy contracts. There are many fixes all over the code base.

assert() and require() is now implemented as a
transction revert, rather than a trap. The error data is returned, and
encoded the same as on Ethereum. Error data is now passed to the calling
contract, all the way up the call stack.

We are happy to release solang v0.2.0 codenamed Berlin today. Aside from containing many small fixes and improvements, this release marks a milestone towards maturing our Substrate compilation target: Any regressions building up since ink! v3.0 are fixed, most notably the metadata format (shoutout and many thanks to external contributor extraymond) and event topics. Furthermore, we are leaving ink! version 3 behind us, in favor of introducing compatibility with the recent ink! 4 beta release and the latest substrate contract node v0.22.1.

print() builtin is now supported and will write to the debug
buffer. Additionally, error messages from the require statements will now be
written to the debug buffer as well. The Substrate contracts pallet prints the
contents of the debug buffer to the console for RPC ("dry-run") calls in case
the runtime::contracts=debug log level is configured.
