AI Summary

Updates the Difftastic structural diff tool with new language parsers, stricter file type detection, and changes to the build environment and memory allocation strategy.

Key Highlights

Added support for Verilog and SystemVerilog
Updated parsers for Erlang, F#, Gleam, Pascal, and Swift
Stricter file detection for UTF-8 and binary formats like zstd/bzip2
CI environment upgraded to Ubuntu 22.04

Breaking Changes

Prebuilt binaries now require a newer glibc version due to the Ubuntu 22.04 upgrade

New Features

Verilog and SystemVerilog support
Updated tree-sitter parsers for five languages
Improved binary file 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.
