v0.3.10 is a performance focused release that additionally ships numerous bugfixes. It adds a `codesize` optimization mode ([3493](https://github.com/vyperlang/vyper/pull/3493)), adds new vyper-specific `#pragma` directives ([3493](https://github.com/vyperlang/vyper/pull/3493)), uses Cancun’s `MCOPY` opcode for some compiler generated code ([#3483](https://github.com/vyperlang/vyper/pull/3483)), and generates selector tables which now feature O(1) performance ([#3496](https://github.com/vyperlang/vyper/pull/3496)).
