AI Summary

Difftastic 0.69.0 enhances syntax-aware diffing by understanding trailing punctuation and adds support for Assembly parsing, while removing support for the Hack language.

Key Highlights

Difftastic now recognizes trailing punctuation as insignificant in Go, Java, JavaScript, Python, Rust, Swift, and TypeScript.
Added support for parsing Assembly files.
Improved parsing for Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Python, Rust, Scala, TypeScript, and VHDL.
Difftastic now considers .gitattributes for determining if a file is binary or text.
Removed support for Hack parser as the upstream is no longer maintained.

Breaking Changes

.php files starting with <?hh are now treated as text (Hack support removed).
Difftastic now requires Rust 1.85 or later to build.

New Features

Trailing punctuation semantic diffing
Assembly parsing support
.gitattributes file detection support

Full Release Notes

Difftastic is a structural diff tool that understands syntax. See [the manual](https://difftastic.wilfred.me.uk/) to get started, and [the changelog](https://github.com/Wilfred/difftastic/blob/master/CHANGELOG.md) for historical changes.

## Diffing

Difftastic now understands when trailing punctuation isn't significant, so `foo(1,)` and `foo(1)` are treated as "no syntactic changes". This is supported for Go, Java, JavaScript, Python, Rust, Swift and TypeScript.

### Parsing

Added support for Assembly.

Substantially improved parsing for Perl.

Improved parsing for Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Python, Rust, Scala, TypeScript and VHDL.

Removed support for Hack, as the upstream parser is no longer maintained. `.php` files starting with `<?hh` are now treated as text.

### File Detection

Difftastic now considers `.gitattributes` when deciding if a file is binary, recognising both the `-text` and `binary` attributes.

### Build

Difftastic now requires Rust 1.85 or later to build.
