# Changelog
All notable changes to `aihc-parser` will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
## [Unreleased]
## [1.0.0.4] - 2026-07-26
### Added
- Added `Addr#` literal syntax and expanded GHC layout oracle coverage.
- Added a developer-only public fuzz registry for downstream property suites.
- Added a `Read` instance for `FixityAssoc` so downstream metadata containing
operator fixities can be persisted and restored.
### Changed
- Improved parser throughput and reduced allocations across large Stackage
inputs and deeply nested syntax.
- Moved development to the standalone
[`ai-haskell-compiler/aihc-parser`](https://github.com/ai-haskell-compiler/aihc-parser)
repository, including the full test, progress, doctest, fuzz, and
compatibility CI configuration.
### Fixed
- Aligned multiline `case` scrutinee layout with GHC.
## [1.0.0.3] - 2026-06-01
### Changed
- Simplified the Cabal package synopsis for cleaner Hackage metadata.
- Added `tested-with` metadata for supported GHC versions and tightened
package bounds to the validated dependency range.
### Fixed
- Preserved source-span annotations on binder names so downstream consumers can
locate binders parsed from declarations such as foreign imports.
## [1.0.0.2] - 2026-05-28
### Fixed
- Removed the internal `parser-tooling-common` and `parser-test-support`
sublibraries from the published Cabal package so Hackage exposes only the
core `aihc-parser` library.
## [1.0.0.1] - 2026-05-28
### Fixed
- Removed internal progress executables from the published Cabal package so
Hackage lists `aihc-parser` as library-only.
- Included parser fixture files in the source distribution so Hackage can run
the package test suite and report coverage.
## [1.0.0.0] - 2026-05-27
### Added
- Initial stable release of the from-scratch Haskell parser package.
- Public parser, lexer, syntax, pretty-printer, shorthand, token, and
parenthesis-insertion modules.
- Oracle-backed parser validation against GHC with parse/pretty round-trip
fingerprint checks.
- Haskell2010 and extension coverage tracking, including the current fully
implemented Haskell2010 baseline and supported tracked extensions.
