- **changed** — Trailing punctuation is now treated as insignificant in diffs for Go, Java, JavaScript, Python, Rust, Swift and TypeScript, so foo(1,) and foo(1) are treated as no syntactic changes
- **added** — Added support for Assembly language
- **changed** — Substantially improved parsing for Perl
- **changed** — Improved parsing for Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Python, Rust, Scala, TypeScript and VHDL
- **removed** — Removed support for Hack, as the upstream parser is no longer maintained
- **changed** — Files starting with <?hh are now treated as text instead of Hack
- **changed** — Difftastic now considers .gitattributes when deciding if a file is binary, recognising both the -text and binary attributes
- **changed** — Difftastic now requires Rust 1.85 or later to build

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Removed support for Hack, as the upstream parser is no longer maintained.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.
