AI Summary

This release focuses on parsing improvements, including new language support and stricter file detection, alongside a shift in the build environment.

Key Highlights

  • Updated parsers for multiple languages (Erlang, F#, Gleam, etc.)
  • Added support for Verilog and SystemVerilog
  • Switched CI to Ubuntu 22.04

Breaking Changes

  • Prebuilt binaries require newer glibc version due to Ubuntu 22.04 switch

New Features

  • Verilog/SystemVerilog support
  • Updated tree-sitter parsers
  • Stricter UTF-8 detection

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.

### Parsing

Updated to the latest tree-sitter parser for Erlang, F#, Gleam, Pascal and Swift.

File detection is now stricter for UTF-8, and recognises more compression file types as binary (e.g. zstd or bzip2).

Added support for Verilog and SystemVerilog.

### Build

CI on GitHub now uses Ubuntu 22.04 for Linux builds (previously Ubuntu 20.04), so prebuilt binaries will require a newer glibc version to run.

### Internal

Difftastic has switched from MiMalloc to Jemalloc for allocation. This is modest performance regression (up to 20% longer runtime in testing). Jemalloc is currently easier to build (see issue #805) and has fewer pathological performance corner cases.
