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:

+--- means no change in the manuals is called for.
+When you add a new item, please add it without either +++ or ---
+so we will look at it and add it to the manual.
+
+\f
+* Installation Changes in Emacs 24.2
+
+** New configure option '--enable-gcc-warnings', intended for developers.
+If building with GCC, this enables compile-time checks that warn about
+possibly-questionable C code. On a recent GNU system there should be
+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.
+
+---
+** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and
+/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.
+
+\f
+* Startup Changes in Emacs 24.2
+
+** Emacs no longer searches for `leim-list.el' files beneath the standard
+lisp/ directory. There should not be any there anyway. If you have
+been adding them there, put them somewhere else, eg site-lisp.
+
+\f
+* Changes in Emacs 24.2
+
+** New functions `system-users', `system-groups' return lists of the user
+name, group names known to the system (where possible).
+
+** If your Emacs was built from a bzr checkout, the new variable
+`emacs-bzr-version' contains information about which bzr revision was used.
+
+** 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 at startup, or when customizing a relevant imagemagick-
+option.
+
+*** Setting `imagemagick-types-inhibit' to t now disables the use of
+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.
+
+** Face underlining can now use a wave.
+See the "Face Attributes" section of the Elisp manual.
+
+** 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.
+
+** `mouse-avoidance-banish-position' can now be used to customize
+`mouse-avoidance-mode' further.
+
+** `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 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.
+
+** A new mode for Python.
+This 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
+- 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'.
+
+** Apropos
+
+*** The faces used by Apropos are now directly customizable.
+These faces are named `apropos-symbol', `apropos-keybinding', and so on;
+see the `apropos' Custom group for details.
+
+**** 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.
+
+*** Non-option variables are never matched in `customize-apropos' and
+`customize-apropos-options' (i.e. the prefix argument does nothing for
+these commands now).
+
+** 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.
+
+*** Follow mode no longer works by using advice.
+The option `follow-intercept-processes' has been removed.
+
+** The `server-auth-key' variable can be used to set a permanent
+shared key for Emacs Server.
+
+** In Perl mode, new option `perl-indent-parens-as-block' causes non-block
+closing brackets to be aligned with the line of the opening bracket.
+
+** FIXME something happened to ses.el, 2012-04-17.
+
+** 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
+
++++
+*** New variables `dbus-compiled-version' and `dbus-runtime-version'.
+
++++
+*** The D-Bus object manager interface is implemented.
+
++++
+*** Variables of type :(u)int32 and :(u)int64 accept floating points,
+if their value does not fit into Emacs's integer range.
+
++++
+*** The function `dbus-call-method' works non-blocking now, it can be
+interrupted by C-g. `dbus-call-method-non-blocking' is obsolete.
+
++++
+*** Signals can be sent also as unicast message.
+
++++
+*** The argument list of `dbus-register-signal' has been extended,
+according to the new match rule types of D-Bus. See the manual for
+details.
+
++++
+*** `dbus-init-bus' supports private connections.
+
++++
+*** There is a new function `dbus-setenv'.
+
++++
+** notifications.el supports now version 1.2 of the Notifications API.
+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
+In most cases, assoc+member+push+delq work just as well.
+And in any case it's just a terrible package: ugly semantics, terrible
+inefficiency, and not namespace-clean.
+
+*** bruce.el
+
+*** ledit.el
+
+*** mailpost.el
+
+*** mouse-sel.el
+
+*** patcomp.el
+
+*** cust-print.el
+
+\f
+* New Modes and Packages in Emacs 24.2
+\f
+* Incompatible Lisp Changes in Emacs 24.2
+
++++
+** Docstrings starting with `*' no longer indicate user options.
+Only variables defined using `defcustom' are considered user options.
+The function `user-variable-p' is now an obsolete alias for
+`custom-variable-p'.
+
+** `face-spec-set' no longer sets frame-specific attributes when the
+third argument is a frame (that usage was obsolete since Emacs 22.2).
+
++++
+** The arguments of `dbus-register-signal' are no longer just strings,
+but keywords or keyword-string pairs. The old argument list will
+still be supported for Emacs 24.x.
+
+** The following obsolete variables and varaliases have been removed:
+
+*** `facemenu-unlisted-faces'
+*** `rmail-decode-mime-charset'
+
+\f
+* Lisp changes in Emacs 24.2
+
+** `defun' also accepts a (declare DECLS) form, like `defmacro'.
+The interpretation of the DECLS is determined by `defun-declarations-alist'.
+
+** `macro-declaration-function' is obsolete, use `macro-declarations-alist'.
+
+** New function `set-temporary-overlay-map'.
+
+** New macros `setq-local' and `defvar-local'.
+
+** 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.
+
+** Completion
+
+*** New function `completion-table-with-quoting' to handle completion
+in the presence of quoting, such as file completion in shell buffers.
+
+*** New function `completion-table-subvert' to use an existing completion
+table, but with a different prefix.
+
+** Time
+
+*** `current-time-string' no longer requires that its argument's year
+must be in the range 1000..9999. It now works with any year supported
+by the underlying C implementation.
+
+** `automount-dir-prefix' is obsolete.
+** `buffer-has-markers-at' is obsolete.
+\f
+* Changes in Emacs 24.2 on non-free operating systems
+
+** New configure.bat options on MS-Windows:
+
+*** --without-libxml2 omits support for libxml2, even if its presence
+is detected.
+
+** When invoked with the -nw switch to run on the Windows text-mode terminal,
+Emacs now supports mouse highlight, help-echo (in the echo area), and
+mouse-autoselect-window.
+
