oksolc 0.2.2

Requires Zig 0.17.0.

Solidity compatibility target: 0.8.36.

Changed

• Lower-level Zig ABI size and offset queries and
  ReturnInfo.estimated_return_size now use u256 instead of u32.
• Direct calls to compileSolidityStandardJsonAlloc and
  compileYulStandardJsonAlloc now take a source_errors slice after
  loaded_sources; pass &.{} when source resolution produced no diagnostics.

Fixed

• Preserve ordinary Solidity typing when settings.experimental is enabled
  (#30).
• Traverse deep inheritance and override graphs without fixed recursion limits,
  and keep the stdio service running after internal compiler failures
  (#31).
• Validate each source URL candidate against keccak256 before accepting it,
  continuing to later URLs after a hash mismatch. Retain hash diagnostics
  alongside callback failures and StackTooDeep exceptions in sequential and
  parallel compilation (#32).
• Use cycle-aware mapping detection so recursive structs are not misclassified
  as containing mappings (#33).
• Materialize string and hexadecimal literals when wrapping fixed bytes in
  user-defined value types (#34).
• Allow state variable writes qualified by contract name, including immutables
  and internal function pointers (#35).
• Support deleting immutable variables during construction
  (#36).
• Match solc 0.8.36 version-range comparisons for large numeric pragma
  components (#37).
• Keep ABI calldata sizes, strides, and offsets exact across the 4 GiB boundary
  (#38).
• Keep static external-call return size totals exact across the 4 GiB boundary
  (#39).

Compatibility

• ABI calldata layouts and static return size totals above 2^32 - 1 bytes use
  exact u256 arithmetic instead of reproducing solc 0.8.36's 32-bit wrapping.
  See the documented compatibility exceptions.
