AI Summary

This release updates Difftastic's parsing capabilities for multiple languages and improves file detection logic. It also migrates the build infrastructure to Ubuntu 22.04 and switches the memory allocator to Jemalloc.

Key Highlights

Updated parsers for Erlang, F#, Gleam, Pascal, and Swift
Added support for Verilog and SystemVerilog
Stricter file detection for UTF-8 and recognition of more binary compression formats
CI migration to Ubuntu 22.04

Breaking Changes

Requires newer glibc version to run prebuilt binaries due to Ubuntu 22.04 migration

New Features

Added support for Verilog and SystemVerilog

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.
