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\
