Solidity v0.8.21 was just released!

We just released Solidity 0.8.21! :rocket:

This latest version allows qualified access to events from other contracts, and we also relaxed restrictions on the initialization of immutable variables.

Important Bugfixes:

  • Code Generator: Always generate code for the expression in .selector
    in the legacy code generation pipeline.
  • Yul Optimizer: Fix FullInliner
    step (i
    ) not preserving the evaluation order of arguments passed into inlined functions in code that is not in expression-split form (i.e. when using a custom optimizer sequence in which the step not preceded by ExpressionSplitter (x)).

Language Features:

  • Allow qualified access to events from other contracts.
  • Relax restrictions on initialization of immutable variables. Reads and writes may now happen at any point at construction time outside of functions and modifiers. Explicit initialization is no longer mandatory.
