# Changelog

## [Next version]

### Building/Packaging changes

* The Nix flake's `buildIdris` function now returns a set with `executable` and
  `library` attributes. These supersede the now-deprecated `build` and
  `installLibrary` attributes. `executable` is the same as `build` and `library`
  is a function that takes an argument determining whether the library should be
  installed with sourcecode files or not; other than that, `library`
  functionally replaces `installLibrary`.

* The Nix flake now exposes the Idris2 API package as `idris2-api` and Idris2's
  C support library as `support`.

### Language changes

### Compiler changes

#### NodeJS Backend

* The NodeJS executable output to `build/exec/` now has its executable bit set.
  That file already had a NodeJS shebang at the top, so now it is fully ready to
  go after compilation.

### Library changes

#### Prelude

#### Base

* `Data.List.Lazy` was moved from `contrib` to `base`.

* Added an `Interpolation` implementation for primitive decimal numeric types and `Nat`.

* Added append `(++)` for `List` version of `All`.

#### Contrib

* `Data.List.Lazy` was moved from `contrib` to `base`.

* Existing `System.Console.GetOpt` was extended to support errors during options
  parsing in a backward-compatible way.
