Fish shell 2.2 发布了，FISH Shell 是一个动态 SHELL，提供命令自动完成、智能脚本、帮助信息自动完成和基于 web 配置等特性。
该版本值得关注的改进有： Abbreviations: the new `abbr` command allows for interactively-expanded abbreviations, allowing quick access to frequently-used commands (#731). Vi mode: run `fish_vi_mode` to switch fish into the key bindings and prompt familiar to users of the Vi editor (#65). New inline and interactive pager, which will be familiar to users of zsh (#291). Underlying architectural changes: the `fishd` universal variable server has been removed as it was a source of many bugs and security problems. Notably, old fish sessions will not be able to communicate universal variable changes with new fish sessions. For best results, restart all running instances of `fish`. The web-based configuration tool has been redesigned, featuring a prompt theme chooser and other improvements. New German, Brazilian Portuguese, and Chinese translations.
