## Language changes
- Unsigned integer operators have been fixed to allow promotion of the first operand.
- Conversions to unsigned integers are unchecked at runtime, imitating earlier Nim
versions. The documentation was improved to acknowledge this special case.
See https://github.com/nim-lang/RFCs/issues/175 for more details.
