0.71.0

Difftastic is a structural diff tool that understands syntax. See [the manual](https://difftastic.wilfred.me.uk/introduction.html) to get started, and [the changelog](https://github.com/Wilfred/difftastic/blob/master/CHANGELOG.md) for historical changes.

### Diffing

Improved performance, particularly for line-based diffs or pathological cases (e.g. an extremely long line).

Linear diffs (used in line-based diffs and word highlighting) have changed from the Wu-Manber algorithm to the Histogram algorithm. This is a modest runtime improvement and a large improvement for memory usage in worst case scenarios.

Some diff results have slightly changed, although the diff quality should be similar. (Please file bugs if not.)

### Parsing

Improved C++, Dockerfile, Haskell, JavaScript, Makefile, Perl, Ruby, Rust, Scala and TypeScript.

Improved heuristics and the default globs used for language detection.

Removed Hare support (upstream parser is no longer maintained).

### Command Line Interface

`--context` can now be set with the short flag `-c`.

### Release

Prebuilt binaries attached to releases now include the version in the filename.
