I'm finally reaching a point with difftastic where I'm pretty happy with performance. 0.22 has some effective heuristics for making the tree diff faster, and 0.23 will have Myers' diff algorithm for text.

I've been impressed with code written by Fable in my testing:
Difftastic: found small optimisations in a hot loop I'd already profiled extensively. Helped me prototype Dijkstra to A* too (hard to find a good heuristic).
Garden: Found some real bugs in my simplistic typechecker.
Difftastic 0.69 is out! This is a pretty big release:
* Semantically insignificant commas are now ignored
* Difftastic now respects .gitattributes
* Added assembly support and improved 13 other languages
I've released difftastic 0.68! A smaller update, but still worth upgrading:
* Improved Bash, C, Go, Lua, Nix, Perl, Python, Rust, Scala, Swift and YAML parsing.
* Minor display and git compatibility fixes.
