* [Topology transformations](https://github.com/fluencelabs/aqua/tree/main/model/transform) were completely rewritten: the same Aqua scripts may produce different AIR, probably more efficient, but new bugs might be introduced as well ([#371](https://github.com/fluencelabs/aqua/pull/371))
* CLI: as an effort to move all the Fluence services management routines to Aqua, uploading files to Fluence's companion IPFS is now available via Aqua CLI ([#390](https://github.com/fluencelabs/aqua/pull/390))
* CLI: path to [@fluencelabs/aqua-lib](https://doc.fluence.dev/aqua-book/libraries/aqua-lib) is provided as an imports folder by default. `import "@fluencelabs/aqua-lib/builtin.aqua"` should always work now, even outside of an NPM project ([#384](https://github.com/fluencelabs/aqua/pull/384))

* 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](https://github.com/fluencelabs/aqua/pull/358))
* Added timeout parameter support for `aqua run` ([#360](https://github.com/fluencelabs/aqua/pull/360))

* Now Aqua compiler emits JS/TS code for [Fluence JS 0.14](https://www.npmjs.com/package/@fluencelabs/fluence). The new JS/TS SDK is heavily rewritten to [support async service functions declaration](https://doc.fluence.dev/docs/fluence-js/3\_in\_depth#using-asynchronous-code-in-callbacks). It also embeds a deeply refactored [AquaVM](https://github.com/fluencelabs/aquavm). ([#334](https://github.com/fluencelabs/aqua/pull/334))

* UX improvements for CLI and JS/TS backend ([#307](https://github.com/fluencelabs/aqua/pull/307), [#313](https://github.com/fluencelabs/aqua/pull/313), [#303](https://github.com/fluencelabs/aqua/pull/303), [#305](https://github.com/fluencelabs/aqua/pull/305), [#301](https://github.com/fluencelabs/aqua/pull/301), [#302](https://github.com/fluencelabs/aqua/pull/302))
### [0.3.1](https://github.com/fluencelabs/aqua/releases/tag/0.3.1) – September 13, 2021

*`aqua` is the name of the compiler CLI command now (was `aqua-cli`) ([#278](https://github.com/fluencelabs/aqua/pull/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](https://github.com/fluencelabs/aqua/pull/278))
* Now you can have a file that contains only a header with imports, uses, declares, and exports, and no new definitions ([#274](https://github.com/fluencelabs/aqua/pull/274))
### [0.2.1](https://github.com/fluencelabs/aqua/releases/tag/0.2.1) – August 31, 2021
* Javascript build of the compiler is now distributed via NPM: to run without Java, use `aqua-js` command ([#256](https://github.com/fluencelabs/aqua/pull/256))

### [0.2.0](https://github.com/fluencelabs/aqua/releases/tag/0.2.0) – August 27, 2021
* Now the compiler emits AIR with the new `(ap` instruction, hence it's not backwards compatible ([#241](https://github.com/fluencelabs/aqua/pull/241))
* Many performance optimizations and bugfixes ([#255](https://github.com/fluencelabs/aqua/pull/255), [#254](https://github.com/fluencelabs/aqua/pull/254), [#252](https://github.com/fluencelabs/aqua/pull/252), [#249](https://github.com/fluencelabs/aqua/pull/249))

### 0.1.10 – July 26, 2021
* Added `<<-` operator to push a value into a stream, see #[214](https://github.com/fluencelabs/aqua/pull/214), [#209](https://github.com/fluencelabs/aqua/issues/209).
