GNU Emacs NEWS -- history of user-visible changes. Copyright (C) 2021 Free Software Foundation, Inc. See the end of the file for license conditions. Please send Emacs bug reports to '[email protected]'. If possible, use 'M-x report-emacs-bug'. This file is about changes in Emacs version 29. See file HISTORY for a list of GNU Emacs versions and release dates. See files NEWS.28, NEWS.27, ..., NEWS.18, and NEWS.1-17 for changes in older Emacs versions. You can narrow news to a specific version by calling 'view-emacs-news' with a prefix argument or by typing 'C-u C-h C-n'. Temporary note: +++ indicates that all relevant manuals in doc/ have been updated. --- means no change in the manuals is needed. When you add a new item, use the appropriate mark if you are sure it applies, and please also update docstrings as needed. * Installation Changes in Emacs 29.1 * Startup Changes in Emacs 29.1 * Changes in Emacs 29.1 ** Help --- *** Jumping to function/variable source now saves mark before moving point. Jumping to source from "*Help*" buffer moves the point when the source buffer is already open. Now, the old point is pushed to mark ring. * Editing Changes in Emacs 29.1 --- ** Indentation of 'cl-flet' and 'cl-labels' has changed. These forms now indent like this: (cl-flet ((bla (x) (* x x))) (bla 42)) This change also affects 'cl-macrolet', 'cl-flet*' and 'cl-symbol-macrolet'. +++ ** New user option 'translate-upper-case-key-bindings'. This can be set to nil to inhibit translating upper case keys to lower case keys. +++ ** New command 'ensure-empty-lines'. This command increases (or decreases) the number of empty lines before point. --- *** Improved mouse behavior with auto-scrolling modes. When clicking inside the `scroll-margin' or `hscroll-margin' region the point is now moved only when releasing the mouse button. This no longer results in a bogus selection, unless the mouse has been effectively dragged. * Changes in Specialized Modes and Packages in Emacs 29.1 ** image-dired --- *** New command for the thumbnail buffer. The new command 'image-dired-unmark-all-marks' has been added with a binding in the menu. --- *** info-look specs can now be expanded at run time instead of a load time. The new ':doc-spec-function' element can be used to compute the ':doc-spec' element when the user asks for info on that particular mode (instead of at load time). ** subr-x +++ *** New macro 'with-memoization' provides a very primitive form of memoization ** ansi-color.el --- *** Support for ANSI 256-color and 24-bit colors. 256-color and 24-bit color codes are now handled by ANSI color filters and displayed with the specified color. ** term-mode --- *** Support for ANSI 256-color and 24-bit colors, italic and other fonts. Term-mode can now display 256-color and 24-bit color codes. It can also handle ANSI codes for faint, italic and blinking text, displaying it with new 'ansi-term-faint/italic/slow-blinking/fast-blinking' faces. * New Modes and Packages in Emacs 29.1 +++ ** New mode 'erts-mode'. This mode is used to edit files geared towards testing actions in Emacs buffers, like indentation and the like. The new ert function 'ert-test-erts-file' is used to parse these files. * Incompatible Lisp Changes in Emacs 29.1 --- ** The 'inhibit-changing-match-data' variable is now obsolete. Instead, functions like 'string-match' and 'looking-at' now take an optional 'inhibit-modify' argument. --- ** 'gnus-define-keys' is now obsolete. Use 'define-keymap' instead. --- ** MozRepl has been removed from js.el. MozRepl was removed from Firefox in 2017, so this code doesn't work with recent versions of Firefox. * Lisp Changes in Emacs 29.1 +++ ** New major mode 'clean-mode'. This is a new major mode meant for debugging. It kills absolutely all local variables and removes overlays and text properties. +++ ** 'kill-all-local-variables' can now kill all local variables. If given the new optional KILL-PERMANENT argument, also kill permanent local variables. +++ ** Third 'mapconcat' argument 'separator' is now optional. An explicit nil always meant the empty string, now it can be left out. --- ** Themes can now be made obsolete. Using 'make-obsolete' on a theme is now supported. This will make 'load-theme' issue a warning when loading the theme. +++ ** New function 'define-keymap'. This function allows defining a number of keystrokes with one form. +++ ** New macro 'defvar-keymap'. This macro allows defining keymap variables more conveniently. * Changes in Emacs 29.1 on Non-Free Operating Systems ---------------------------------------------------------------------- This file is part of GNU Emacs.

Archlinux 系统下 emacs 已经升级到 29 了（archlinuxcn 源）；

这版本真是够猛的，是arch linux独立维护的版本吗？
cn 源自己打包的

现在有遇到哪些不兼容的package吗？
应该就是对应现在 emacs 的 master 吧？
Org mode 有 breaking change，目前最新的 org 9.5 版本瘦身了，把一些功能放到 nongnu 上，需要用户安装 contrib 。详见 Release notes | Org mode
使用 Purcell 配置的用户需要更新才能用 29.0.50， `ob-ledger` may be deprecated in the git branch emacs29 · Issue #791 · purcell/emacs.d · GitHub
路子野啊。。
他的配置，入门学习下还是不错的，用了有近一年。可以掌握一些基础的 elisp 用法。
不过这个配置缺点很明显，不支持lsp，而且 Windows下 启动太慢（8s），Mac和Linux 上需要3.5s 还能接受。
我现在也是基于他的配置，使用 use-package 自己攒配置了，控制在 Mac/Linux 启动 1s，Windows 3s 以内。

刚发现回复错了，感谢您的回复；从使用他人的配置到形成自己的配置就是进步，恭喜！点开您的签名已经找到配置了
orgmode 变动确实大呀
看 nongnu 仓库 org-contrib 的介绍叫 unmaintained org addons ，看起来被摘出去也是不维护了
估计只是 org-mode 不再维护，让社区的所有人都可以参与维护这些包（在 nongnu 没了限制)，减轻 org-mode 的维护负担。
反正这些包我是一个还用不到，对 org 的使用还不深入 
。
我连 org-modules 里面的几个包都一个用不到，不知道大家有没用到？
这个几个是影响加载速度的
(ol-doi ol-w3m ol-bbdb ol-bibtex ol-docview ol-gnus ol-info ol-irc ol-mhe ol-rmail ol-eww)
你这是什么主题啊？感觉挺喜欢的。
换成了arch里面的gcc emacs，好像默认就是最新版编译出来的
最近刚升级到了 29，使用起来好像没什么区别。
