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

Breaking semantic change: Stream restrictions. This fixes many obscure bugs which happened when using streams inside for cycles (#321)
This version of Aqua is not compatible with fldist so far (cannot run the emitted AIR via fldist). Use aqua --run to run Aqua instead (#358)
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.

New language feature: closures (#327)
New CLI option --scheduled to compile Aqua for the Fluence's Script Storage (#355)
Bugfixes for using streams to construct more complex streams (#277)
Better errors rendering (#322, #337)
Bugfix for comparing Option types (#343)

Now Aqua compiler emits JS/TS code for Fluence JS 0.14. The new JS/TS SDK is heavily rewritten to support async service functions declaration. It also embeds a deeply refactored AquaVM. (#334)
Various bugfixes for AIR generation and the compiler behavior (#328, #335, #336, #338)

aqua run -i aqua/caller.aqua -f "callFunc(\"arg1\",\"arg2\")"

Now .aqua extension in imports is optional: you may import "file.aqua" or just import "file" with the same effect (#292)
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).

TypeScript output of the compiler now targets a completely rewritten TypeScript SDK (#251)
Constants are now UPPER_CASED, including always-available HOST_PEER_ID and INIT_PEER_ID (#260)
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)
Now you can have a file that contains only a header with imports, uses, declares, and exports, and no new definitions (#274)

Javascript build of the compiler is now distributed via NPM: to run without Java, use aqua-js command (#256)
Now dots are allowed in the module declarations: module Space.Module & many bugfixes (#258)

Now the compiler emits AIR with the new (ap instruction, hence it's not backwards compatible (#241)
Many performance optimizations and bugfixes (#255, #254, #252, #249)

Aqua file header changes: module, declares, use, export expressions (#245), see Imports and Exports for the docs.
Experimental Scala.js build of the compiler (#247)

Can have functions consisting of a return operand only, returning a literal or an argument

Added host_peer_id , a predefined constant that points on the relay if Aqua compilation is configured so, and on %init_peer_id% otherwise, see #218.
