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

0.7.1 – March 25, 2022

• Now Aqua supports arithmetic operators (e.g. 1 + x), arrow calls in any place (e.g. for x <- foo(3 + bar()) par...) and simple comparison (e.g. if a > 3) (#461 -> #410)

0.2.1 – August 31, 2021

• Now dots are allowed in the module declarations: module Space.Module & many bugfixes (#258)
