This release of fish includes a number of improvements over fish 3.6.4, detailed below. Although work continues on the porting of fish internals to the Rust programming language, that work is not included in this release. fish 3.7.0 and any future releases in the 3.7 series remain C++ programs.

Notable improvements and fixes

• Improvements to the history pager, including:
• The history pager will now also attempt subsequence matches (#9476), so you can find a command line like git log 3.6.1..Integration_3.7.0 by searching for gitInt.
• Opening the history pager will now fill the search field with a search string if you’re already in a search (#10005). This makes it nicer to search something with ↑ and then later decide to switch to the full pager.
• Closing the history pager with enter will now copy the search text to the commandline if there was no match, so you can continue editing the command you tried to find right away (#9934).
• Performance improvements for command completions and globbing, where supported by the operating system, especially on slow filesystems such as NFS (#9891, #9931, #10032, #10052).
• fish can now be configured to wait a specified amount of time for a multi-key sequence to be completed, instead of waiting indefinitely. For example, this makes binding kj to switching modes in vi mode possible.
• The timeout can be set via the new fish_sequence_key_delay_ms variable (#7401), and may be set by default in future versions.
