(from the bin and libexec directories, respectively). The former is
no longer relevant, the latter is replaced by lisp (in vc-sccs.el).
+** The configuration option '--enable-use-lisp-union-type' has been
+renamed to '--enable-check-lisp-object-type', as the resulting
+Lisp_Object type no longer uses a union to implement the compile time
+check that this option enables.
+
\f
* Startup Changes in Emacs 24.2
lisp/ directory. There should not be any there anyway. If you have
been adding them there, put them somewhere else, eg site-lisp.
+---
+** The `--no-site-lisp' command line option now works for Nextstep builds.
+
\f
* Changes in Emacs 24.2
+** Help changes
+
+*** `C-h f' (describe-function) can now perform autoloading.
+When this command is called for an autoloaded function whose docstring
+contains a key substitution construct, that function's library is
+automatically loaded, so that the documentation can be shown
+correctly. To disable this, set `help-enable-auto-load' to nil.
+
+*** `C-h f' now reports previously-autoloaded functions as "autoloaded",
+even after their associated libraries have been loaded (and the
+autoloads have been redefined as functions).
+
+** The function `current-time' now returns extended-format time stamps
+(HIGH LOW USEC PSEC) that use picosecond resolution; the PSEC
+component is new. PSEC is typically a multiple of 1000 on current
+machines. Other functions that use this format, such as
+file-attributes and format-time-string, have been changed accordingly.
+Old-format time stamps are still accepted.
+
** New functions `system-users', `system-groups' return lists of the user
name, group names known to the system (where possible).
`imagemagick-filter-types' returns the list of types that will be
treated as images.
+*** Images displayed via ImageMagick now support transparency and the
+:background image spec property.
+
+** Face underlining can now use a wave.
+See the "Face Attributes" section of the Elisp manual.
+
+** New fringe bitmap exclamation-mark.
+
** String values for `initial-buffer-choice' also apply to emacsclient
frames, if emacsclient is only told to open a new frame without
specifying any file to visit or expression to evaluate.
*** You can now click mouse-3 in the coding system indicator to
invokes `set-buffer-file-coding-system'.
++++
+** Setting `enable-remote-dir-locals' to non-nil allows directory
+local variables on remote hosts.
+
++++
+** `insert-char' is now a command, and `ucs-insert' an obsolete alias
+for it.
+
\f
* Editing Changes in Emacs 24.2
** `mouse-avoidance-banish-position' can now be used to customize
`mouse-avoidance-mode' further.
+** `M-=' is now bound to `count-words', not `count-words-region'.
+
** `C-M-f' and `C-M-b' will now move to the path name separator
character when doing minibuffer filename prompts.
** `goto-char' is now bound to `M-g c'.
+** New command `C-x r M-w' (copy-rectangle-as-kill).
+It copies the region-rectangle as the last rectangle kill.
+
+** New input method `vietnamese-vni'.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.2
+** Term changes
+
+The variables `term-default-fg-color' and `term-default-bg-color' are
+now deprecated in favor of the `term-face' face, that you can
+customize. Also, it is now possible to customize how are displayed the
+ANSI terminal colors and styles by customizing the corresponding
+`term-color-<COLOR>', `term-color-underline' and `term-color-bold'
+faces.
+
** CL's main entry is now (require 'cl-lib).
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
i.e. all its definitions have the "cl-" prefix.
The old `cl' is now deprecated and is nothing more than a bunch of aliases that
provide the old non-prefixed names.
-** VHDL-mode
-- Support for ghdl (free vhdl compiler). Now default.
-- Add/update support for VHDL-AMS packages.
-- Update to VHDL'02 standard.
-- Accept \r and \f as whitespace.
+** Desktop
+
+*** `desktop-path' no longer includes the "." directory. Desktop
+files are now located in ~/.emacs.d by default.
+
+** Python mode
+
+A new version of python.el, which provides several new features, including:
+per-buffer shells, better indentation, Python 3 support, and improved
+shell-interaction compatible with iPython (and virtually any other
+text based shell).
+
+*** Some user options have been replaced/renamed:
+Old defcustom: | New defcustom:
+python-indent | python-indent-offset
+python-guess-indent | python-indent-guess-indent-offset
+python-pdbtrack-do-tracking-p | python-pdbtrack-activate
+python-use-skeletons | python-skeleton-autoinsert
+
+*** Some user options have been removed:
+
+**** `python-indent-string-contents': Strings are never indented.
+
+**** `python-honour-comment-indentation':
+Comments are never considered as indentation markers themselves.
+
+**** `python-continuation-offset': Indentation is automatically
+calculated in a pep8 compliant way depending on the context.
+
+**** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist':
+Have no direct mapping as the shell interaction is completely different.
+
+**** `python-python-command', `python-jython-command':
+Replaced by `python-shell-interpreter'.
+
+**** `inferior-python-filter-regexp', `python-remove-cwd-from-path',
+`python-pdbtrack-minor-mode-string', `python-source-modes':
+No longer relevant.
+
+*** Some commands have been replaced:
+Old command | New command
+python-insert-class | python-skeleton-class
+python-insert-def | python-skeleton-def
+python-insert-for | python-skeleton-for
+python-insert-if | python-skeleton-if
+python-insert-try/except | python-skeleton-try
+python-insert-try/finally | python-skeleton-try
+python-insert-while | python-skeleton-while
+python-find-function | python-nav-jump-to-defun
+python-next-statement | python-nav-forward-sentence
+python-previous-statement | python-nav-backward-sentence
+python-send-buffer | python-shell-send-buffer
+python-send-defun | python-shell-send-defun
+python-send-region | python-shell-send-region
+python-send-region-and-go | Emulate with python-shell-send-region and
+ python-shell-switch-to-shell
+python-send-string | python-shell-send-string
+python-switch-to-python | python-shell-switch-to-shell
+python-describe-symbol | python-eldoc-at-point
+
+** VHDL mode
+
+*** The free software compiler GHDL is supported (and now the default).
+
+*** Support for the VHDL-AMS packages has been added/updated.
+
+*** Updated to the 2002 revision of the VHDL standard.
+
+*** Accepts \r and \f as whitespace.
** Diff mode
** Ediff now uses the same color scheme as Diff mode
on high color displays.
+** Flymake uses fringe bitmaps to indicate errors and warnings.
+See flymake-fringe-indicator-position, flymake-error-bitmap and
+flymake-warning-bitmap.
+
** `sh-script'
*** Pairing of parens/quotes uses electric-pair-mode instead of skeleton-pair.
*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
**** The old options whose values specified faces to use were removed
(i.e. `apropos-symbol-face', `apropos-keybinding-face', etc.).
+** Buffer Menu
+This package has been rewritten to use Tabulated List mode.
+
+*** Option `Buffer-menu-buffer+size-width' is now obsolete.
+Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead.
+
** Calendar
*** The calendars produced by cal-html include holidays.
** erc will look up server/channel names via auth-source and use the
channel keys found, if any.
+** Dired
+
+*** `dired-do-async-shell-command' executes each file sequentially
+if the command ends in `;' (when operating on multiple files).
+Otherwise, it executes the command on each file in parallel.
+
** FFAP
*** The option `ffap-url-unwrap-remote' can now be a list of strings,
** which-function-mode now applies to all applicable major modes by default.
+** Tramp
+
++++
+*** The syntax has been extended in order to allow ad-hoc proxy
+definitions. See the manual for details.
+
++++
+*** Remote processes are now supported also on remote Windows host.
+
** D-Bus
+++
The function `notifications-get-capabilities' returns the supported
server properties.
+** Package Menu
+
+*** Newly-available packages are listed in the Package Menu as "new",
+and sorted above the other "available" packages by default.
+
** Tabulated List and packages derived from it
*** New command `tabulated-list-sort', bound to `S', sorts the column
The function `user-variable-p' is now an obsolete alias for
`custom-variable-p'.
++++
+** The return values of `defalias', `defun' and `defmacro' have changed,
+and are now undefined. For backwards compatibility, defun and
+defmacro currently return the name of the newly defined function/macro
+but this should not be relied upon.
+
** `face-spec-set' no longer sets frame-specific attributes when the
third argument is a frame (that usage was obsolete since Emacs 22.2).
*** `facemenu-unlisted-faces'
*** `rmail-decode-mime-charset'
+*** `last-input-char' and `last-command-char'
\f
* Lisp changes in Emacs 24.2
+** New functions `autoloadp' and `autoload-do-load'.
+
+** `function-get' fetches the property of a function, following aliases.
+
+** `toggle-read-only' accepts a second argument specifying whether to
+print a message, if called from Lisp.
+
+** CL-style generalized variables are now in core Elisp.
+`setf' is autoloaded and `push' and `pop' accept generalized variables.
+
** `defun' also accepts a (declare DECLS) form, like `defmacro'.
The interpretation of the DECLS is determined by `defun-declarations-alist'.
** New error type and new function `user-error'. Doesn't trigger the debugger.
** The functions get-lru-window, get-mru-window and get-largest-window
-now accept a third argument to avoid chosing the selected window.
+now accept a third argument to avoid choosing the selected window.
** Completion
must be in the range 1000..9999. It now works with any year supported
by the underlying C implementation.
+** New function file-name-base.
+
+** New function `tty-top-frame' returns the topmost frame of a text terminal.
+
** `automount-dir-prefix' is obsolete.
** `buffer-has-markers-at' is obsolete.
\f
specifies how to display them: as a hexadecimal code in a box, a thin
1-pixel space, an empty box, etc.
-*** New input methods: farsi, farsi-translit, bulgarian-alt-phonetic.
+*** New input methods for Farsi and Bulgarian
+(farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic).
*** `nobreak-char-display' now also highlights Unicode hyphen chars
(U+2010 and U+2011).
