 ## [Unreleased]
 
+## [0.2.0] - 2022-02-17

 ### Added
 
-- Pre-built binaries for x86_64-linux and aarch64-linux
+- Pre-built binaries for x86_64-linux and aarch64-linux.
+- Made the logic of the `or-default` (`a or b`) node
+  to be equal to the binary operator (`a $operator b`).
+  This increases consistency across the same family of elements.
+- Remove users freedom to insert newlines
+  before the `?` in pattern bindings (`a ? b`).
+
+  Inserting a newline after the `?` is still possible.
+
+  This increases consistency on where to break a long pattern binding.
+
+- Remove space on empty containers (`[]`, `{}`).
+- Add a `--version` flag to the CLI.
+- Reduce 1 indentation level in `let-in` expressions,
+  when the target expression is a parenthesis, attr-set, list, or string.
+- Support inline comments on lists, attr-sets, and let-in expressions.
+- String interpolations in multi-line strings
+  now have a nice-looking indentation.
+
+### Fixed
+
+- A bug in the current position counter
+  caused a small percentage of multiline comments in Nixpkgs
+  to be unaligned by one character.
