Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Git Support
Fixed an issue where git with difftastic would terminate with fatal: external diff died when there was an unmerged path.
Parsing
Updated Bash, C, Go, Lua, Nix, Perl, Python, Rust, Scala, Swift and YAML parsers.
Fixed an issue with parsing raw string literals in Rust.
Build
Difftastic now requires Rust 1.77 or later to build.
Difftastic no longer uses jemalloc on any Windows builds. Previously jemalloc was only disabled for MSVC.
Command Line Interface
Improved error reporting when invoked with an invalid number of arguments.
Display
Fixed an issue with inline display where it didn't always respect the value of --context.
Fixed an issue with side-by-side rendering when files contain tabs.
