Full Changelog: https://github.com/dandavison/delta/compare/0.17.0...0.18.0

Thanks to the many contributors! Particular highlights are

Thanks to @bash's work, delta now automatically detects whether your terminal has a light/dark background (unless you specify with --light or --dark):

• Detect Dark/Light Mode from Terminal by @bash in https://github.com/dandavison/delta/pull/1615

@joshtriplett solved the long-standing problem of correctly parsing traditional grep output, e.g. git grep, grep, etc. Until now there had been annoying parse ambiguities related to separator characters in file paths. This is particularly valuable for git grep since it has interesting features such as git grep -W (see https://github.com/dandavison/delta/issues/769)

• Parse filename unambiguously using color escape sequences by @joshtriplett in https://github.com/dandavison/delta/pull/1634

@imbrish fixed two important bugs and added the ability to set a default language (e.g. for executable shell scripts with no file name suffix)

Full Changelog: https://github.com/dandavison/delta/compare/0.16.5...0.17.0

This is a follow-up release providing the various binaries that were not released with 0.16.4. It also makes some adjustments to delta's (rip)grep support.

• Increase number of characters shown in submodule hashes by @dandavison in https://github.com/dandavison/delta/pull/1421
• Fix typo in publishing build job & restore cross-compilation by @nickelc in https://github.com/dandavison/delta/pull/1430
• 3819e94 Drop grep-header-style option by @dandavison
• a28231a Honor grep-header-decoration-style for ripgrep output by @dandavison

Full Changelog: https://github.com/dandavison/delta/compare/0.16.4...0.16.5

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.

Thanks to all contributors for the changes in this release! One particularly exciting contribution is the tweaks to the highlighting algorithm made by @phillipwood in #1244.
