It's 6 months since the last release so this one brings quite a few changes. Thanks very much to all contributors, especially @nickelc for a huge number of contributions, and @wescande for his work on improving whitespace highlighting. With this release delta can now display grep output in (hopefully) exactly the same layout that ripgrep does, but adding syntax highlighting, hyperlinks, and navigation. Use `ripgrep --json ... | delta` for that, or set `grep-output-type = ripgrep` to get that output style from `git grep` etc.

This release does not contain binaries for `x86_64-unknown-linux-musl`, `i686-unknown-linux-gnu`, `arm-unknown-linux-gnueabihf`, or `aarch64-unknown-linux-gnu` because the cross-compilation GitHub Actions jobs were broken at the time of release. I'll issue a follow-up release including them when that's fixed.
