Changelog

Aqua compiler's versioning scheme is the following: 0.BREAKING.ENHANCING.RELEASE

  • 0 shows that Aqua does not meet its vision yet, so syntax and semantics can change quickly
  • BREAKING part is incremented for each breaking change when old .aqua files need to be updated to compile with the new version
  • ENHANCING part is incremented for every syntax addition
  • RELEASE is the release number, shows internal compiler changes, bugfixes that keep the language untouched
