ripgrep 15 is a new major version release of ripgrep that mostly has bug fixes, some minor performance improvements and minor new features.

In case you haven't heard of it before, ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files.

Here are some highlights:

• Several bugs around gitignore matching have been fixed. This includes a commonly reported bug related to applying gitignore rules from parent directories.
• A memory usage regression when handling very large gitignore files has been fixed.
• rg -vf file, where file is empty, now matches everything.
• The -r/--replace flag now works with --json.
• A subset of Jujutsu (jj) repositories are now treated as if they were git repositories. That is, ripgrep will respect jj's gitignores.
• Globs can now use nested curly braces.

Platform support:

• aarch64 for Windows now has release artifacts.
• powerpc64 no longer has release artifacts generated for it. The CI release workflow stopped working, and I didn't deem it worth my time to debug it. If someone wants this and can test it, I'd be happy to add it back.
• ripgrep binaries are now compiled with full LTO enabled. You may notice small performance improvements from this and a modest decrease in binary size.

Performance improvements:

• PERF #2111: Don't resolve helper binaries on Windows when -z/--search-zip isn't used.
• PERF #2865: Avoid using path canonicalization on Windows when emitting hyperlinks.
• PERF #3184: Improve performance of large values with -A/--after-context.
