no warnings; on older and on non-GNU systems the generated warnings
may be useful.
+** The configure option '--disable-maintainer-mode' has been removed,
+as it was confusingly-named and rarely useful.
+
---
** Emacs uses libtinfo in preference to libncurses, if available.
/usr/pkg/lib to the linker search path. You must add them yourself if
you want them.
+---
+** On Mac OS X, configure no longer automatically adds the Fink /sw
+directories to the search path. You must add them yourself if you want them.
+
+---
+** The standalone scripts rcs-checkin and vcdiff have been removed
+(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.

* Startup Changes in Emacs 24.2
** ImageMagick support, if available, is automatically enabled.
It is no longer necessary to call `imagemagick-register-types'
explicitly to install ImageMagick image types; that function is called
-automatically when setting `imagemagick-types-inhibit'.
+automatically at startup, or when customizing a relevant imagemagick-
+option.
*** Setting `imagemagick-types-inhibit' to t now disables the use of
-ImageMagick to view images, set
+ImageMagick to view images. You must call imagemagick-register-types
+afterwards if you do not use customize to change this.
+
+*** The new variable `imagemagick-enabled-types' also affects which
+ImageMagick types are treated as images. The function
+`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.
** 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 prevent the creation of lock files by setting `create-lockfiles'
+to nil. Use with caution, and only if you really need to.
+
++++
+** Using "unibyte: t" in Lisp source files is obsolete.
+Use "coding: raw-text" instead.
+
+** Mode line changes
+
+*** New option `mode-line-default-help-echo' specifies the help text
+(shown in a tooltip or in the echo area) for any part of the mode line
+that does not have its own specialized help text.
+
+*** 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.
+
\f
* Editing Changes in Emacs 24.2
+** Search changes
+
+*** Global `M-s _' starts a symbol (identifier) incremental search,
+and `M-s _' in Isearch toggles symbol search mode.
+`M-s c' in Isearch toggles search case-sensitivity.
+
** M-x move-to-column, if called interactively with no prefix arg, now
prompts for a column number.
** `goto-char' is now bound to `M-g c'.
+** New input method `vietnamese-vni'.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.2
+** 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.
+
+If `cl' provided a feature under the name `foo', then `cl-lib' provides it
+under the name `cl-foo' instead, with the exceptions of the few definitions
+that had to use `foo*' to avoid conflicts with pre-existing Elisp entities,
+which have not been renamed to `cl-foo*' but just `cl-foo'.
+
+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.
+
+** Diff mode
+
+Faces for changes now use the same diff color scheme as in modern VCSes
+where deletions are displayed in red (new faces `diff-refine-removed'
+and `smerge-refined-removed' and new definition of `diff-removed'),
+insertions in green (new faces `diff-refine-added' and
+`smerge-refined-added' and new definition of `diff-added').
+The variable `diff-use-changed-face' defines whether to use
+the face `diff-changed', or `diff-removed' and `diff-added'
+to highlight changes in context diffs.
+
+** Ediff now uses the same color scheme as Diff mode
+on high color displays.
+
+** `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.
+*** `sh-use-smie' lets you choose a new indentation and navigation code.
+
+** reStructuredText mode
+
+*** Rebind nearly all keys making room for more keys and complying
+better to usage in other modes. Describe bindings with C-c C-h.
+
+*** Major revision of indentation working very similar to other
+modes. TAB is your friend.
+
+*** Major revision of filling working fine with most of
+reStructuredText syntax. Support auto-filling.
+
+*** Major revision of comment handling.
+
+*** Major revision of fontification working with `jit-lock-mode'.
+
+*** Cover reStructuredText syntax more closely. Improve
+the experience for Sphinx users.
+
+*** `rst-insert-list' inserts new list or continues existing lists.
+
+*** Extend correct and improve customization.
+
+*** Negative prefix argument always works for `rst-adjust'.
+
+*** Reset window configuration after displaying TOC.
+
+*** Package version in `rst-version'.
+
** New `derived-mode' filter for Ibuffer, bound to `/ M'.
`/ m' is now bound to filter by used-mode, which used to be bound to `/ M'.
**** 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.
+Customize cal-html-holidays to change this.
+
** Customize
*** `custom-reset-button-menu' now defaults to t.
** erc will look up server/channel names via auth-source and use the
channel keys found, if any.
+** FFAP
+
+*** The option `ffap-url-unwrap-remote' can now be a list of strings,
+specifying URL types which should be converted to remote file names at
+the FFAP prompt. The default is now '("ftp").
+
** Follow mode
*** The obsolete variable `follow-mode-off-hook' has been removed.
** 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
+at point, or the Nth column if a numeric prefix argument is given.
+
+** URL
+
+*** Structs made by `url-generic-parse-url' have nil `attributes' slot.
+Previously, this slot stored semicolon-separated attribute-value pairs
+appended to some imap URLs, but this is not compatible with RFC 3986.
+So now the `filename' slot stores the entire path and query components
+and the `attributes' slot is always nil.
+
+*** New function `url-encode-url' for encoding a URI string.
+The `url-retrieve' function now uses this to encode its URL argument,
+in case that is not properly encoded.
+
** Obsolete packages:
*** assoc.el
*** bruce.el
+*** ledit.el
+
*** mailpost.el
*** mouse-sel.el
*** patcomp.el
+*** cust-print.el
+

+
+** New function `set-temporary-overlay-map'.
+

+
+** The functions get-lru-window, get-mru-window and get-largest-window
+now accept a third argument to avoid chosing the selected window.
+
** Completion
*** New function `completion-table-with-quoting' to handle completion
by the underlying C implementation.
** `automount-dir-prefix' is obsolete.
+** `buffer-has-markers-at' is obsolete.

+Emacs now supports mouse highlight, help-echo (in the echo area), and
+mouse-autoselect-window.

\f
* Installation Changes in Emacs 24.1
functionality such as more intelligent indentation, electricity,
support for more variants, including Mercury, and a lot more.
+** Python mode has been replaced with fgallina's python.el.
+Per-buffer shells, solid automatic indentation, Python 2 and 3 support
+out of the box, a revamped shell interaction compatible with iPython
+(and virtually any other text based shell) plus other goodies are
+provided.
