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

Breaking semantic change: Stream restrictions. This fixes many obscure bugs which happened when using streams inside for cycles (#321)

Added timeout parameter support for aqua --run (#360)
You need to update FluenceJS to 0.15.0+ and Fluence Node to v0.0.23+ for Aqua 0.5 support, previous versions will not work.

CLI improvements: --dry run (#290), output directory is created if not present (#287)
Many bugfixes: for imports (#289), TypeScript backend (#285, #294, #298), and language semantics (#275).
​0.3.0 – September 8, 2021
TypeScript output of the compiler now targets a completely rewritten TypeScript SDK (#251)

The compiler is now distributed as @fluencelabs/aqua package (was aqua-cli) (#278)
aqua is the name of the compiler CLI command now (was aqua-cli) (#278)
JVM version of the compiler is now available with aqua-j command; JS build is called by default – so no more need to have JVM installed (#278)
