Release highlights jj fix now supports formatting specific line ranges (allowing you to format only modified lines); see the configuration manual and notes below for more. The new global flag --no-integrate-operation will let you run a command without impacting the repo state or the working copy, which is useful when automated tools may create snapshots in the background.

发布亮点 jj fix 现在支持格式化特定的行范围（允许你仅格式化修改过的行）；有关更多信息，请参阅配置手册和下方的说明。新的全局标志 --no-integrate-operation 允许你在不影响仓库状态或工作副本的情况下运行命令，这在自动化工具可能在后台创建快照时非常有用。

Breaking changes The --pattern flag for file search now defaults to regex: instead of glob:. jj git push --all/--tracked/-r REVSETS no longer fails when revisions to push are private or have conflicts. Bookmarks which aren’t eligible to push will be skipped. Branch/bookmark patterns passed to jj git clone are now saved to jj’s repo settings file instead of .git/config. Git fetch refspecs are set to the default value.

破坏性变更 文件搜索的 --pattern 标志现在默认使用 regex: 而不是 glob:。当要推送的修订版本是私有的或存在冲突时，jj git push --all/--tracked/-r REVSETS 不再报错。无法推送的书签将被跳过。传递给 jj git clone 的分支/书签模式现在保存到 jj 的仓库设置文件中，而不是 .git/config。Git 获取的 refspecs 被设置为默认值。

Deprecations In the templating language, the Operation type’s .tags() function has been deprecated in favor of .attributes().

弃用在模板语言中，Operation 类型的 .tags() 函数已被弃用，取而代之的是 .attributes()。

New features The --pattern flag for file search now accepts various pattern kinds through kind:pattern syntax. A new global flag --no-integrate-operation lets you run a command without impacting the repo state or the working copy. A new config option diff.git.show-path-prefix can be used to suppress the a/ and b/ path prefixes in the diff --git output. jj fix now supports line range-limited formatting via the fix.tools.<name>.line-range-arg and run-tool-if-zero-line-ranges configs. This allows running tools only on modified lines and fine-grained control over when the tool is run. If you have set the line-range-arg config, use --all-lines to match the previous behavior of formatting the entire file. A new replace(pattern, content, replacement) template function is added which supports replacement of content in templates, using a lambda to format replacement text. It supports all string patterns, including regexes with capture groups (e.g. replace(regex:'(\w+) (\w+)', "hello world", |c| c.get(1) ++ " " ++ c.get(2))). New ByteString template type for things like file content. jj gerrit upload now supports the new options --message (-m), --edit and --merged. You can now also pass multiple hashtags by repeating the --hashtag option. New remotes.<name>.fetch-bookmarks/fetch-tags options to configure default fetch targets. JJ_PAGER can now override the ui.pager config, matching JJ_EDITOR for callers that need a jj-specific environment override.

新功能 文件搜索的 --pattern 标志现在通过 kind:pattern 语法支持多种模式类型。新的全局标志 --no-integrate-operation 允许你在不影响仓库状态或工作副本的情况下运行命令。新的配置选项 diff.git.show-path-prefix 可用于在 diff --git 输出中隐藏 a/ 和 b/ 路径前缀。jj fix 现在通过 fix.tools.<name>.line-range-arg 和 run-tool-if-zero-line-ranges 配置支持行范围限制格式化。这允许仅在修改过的行上运行工具，并对工具运行的时机进行细粒度控制。如果你设置了 line-range-arg 配置，可以使用 --all-lines 来恢复之前格式化整个文件的行为。新增了 replace(pattern, content, replacement) 模板函数，支持在模板中替换内容，并使用 lambda 表达式来格式化替换文本。它支持所有字符串模式，包括带有捕获组的正则表达式（例如 replace(regex:'(\w+) (\w+)', "hello world", |c| c.get(1) ++ " " ++ c.get(2))）。新增了用于文件内容等场景的 ByteString 模板类型。jj gerrit upload 现在支持新的选项 --message (-m)、--edit 和 --merged。你现在还可以通过重复 --hashtag 选项来传递多个标签。新增了 remotes.<name>.fetch-bookmarks/fetch-tags 选项以配置默认的获取目标。JJ_PAGER 现在可以覆盖 ui.pager 配置，这与 JJ_EDITOR 一致，适用于需要特定于 jj 的环境变量覆盖的调用者。

Fixed bugs Improving consistency with git handling of .gitignore, including / after entries and \r\r\n for MacOS files. jj status filters untracked paths by fileset #9287. Improved performance for snapshotting, visibly improving jj status speed for large repositories. Pre-existing Git submodule directories are no longer considered conflicts in checkouts. #8065. Fixed a panic in jj gerrit upload when run without -r and the inferred revision was immutable. #9398. jj status respects path filters in working copy summaries. jj git remote rename/remove now updates the trunk() alias. Commands would sometimes incorrectly diagnose a stale working copy and suggest running jj op integrate when it would have no effect. This should now be much less likely to happen in practice. #9314.

修复的 Bug 提高了与 Git 处理 .gitignore 的一致性，包括条目后的 / 和 MacOS 文件的 \r\r\n。jj status 现在通过文件集过滤未追踪路径 (#9287)。改进了快照性能，显著提升了大型仓库中 jj status 的速度。预先存在的 Git 子模块目录在检出时不再被视为冲突 (#8065)。修复了在未指定 -r 且推断出的修订版本不可变时运行 jj gerrit upload 导致的崩溃问题 (#9398)。jj status 在工作副本摘要中遵循路径过滤器。jj git remote rename/remove 现在会更新 trunk() 别名。命令有时会错误地诊断工作副本过时并建议运行 jj op integrate，即使这样做无效。在实践中，这种情况现在发生的可能性大大降低 (#9314)。
