AI Summary

This release updates tree-sitter parsers for several languages, improves file detection for UTF-8 and compression types, and adds support for Verilog and SystemVerilog. Additionally, it updates CI to Ubuntu 22.04 and switches the memory allocator from MiMalloc to Jemalloc.

Key Highlights

  • Updated tree-sitter parsers for Erlang, F#, Gleam, Pascal, and Swift.
  • Added support for Verilog and SystemVerilog languages.
  • Stricter file detection for UTF-8 and recognition of more compression file types as binary.
  • CI updated to Ubuntu 22.04, requiring a newer glibc version for Linux prebuilt binaries.
  • Switched from MiMalloc to Jemalloc for memory allocation.

Breaking Changes

  • Linux prebuilt binaries now require a newer glibc version due to the switch to Ubuntu 22.04 CI.

New Features

  • Support for Verilog and SystemVerilog parsing.

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.
