** The default toolkit has been changed to Gtk+ version 3.
If you don't pass --with-x-toolkit to configure or if you pass
--with-x-toolkit=gtk or --with-x-toolkit=yes, configure will try to build
with Gtk+ version 3, and if that fails, try Gtk+ version 2.
You can explicitly require a specific version by passing
--with-x-toolkit=gtk2 or --with-x-toolkit=gtk3 to configure.

** 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

** The configure 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.

56 57 58
** The configure option '--disable-maintainer-mode' has been removed,
as it was confusingly-named and rarely useful.

** You can use `NO_BIN_LINK=t make install' to prevent the installation
overwriting "emacs" in the installation bin/ directory with a link

** The configure options `--program-prefix', `--program-suffix', and
`--program-transform-name' apply to more than just the installed
binaries.  Now they also affect the man pages, icons, and the
etc/emacs.desktop file; but not the info pages, since this would break
links between the various manuals.

** Emacs uses libtinfo in preference to libncurses, if available.

74 75 76 77 78

** 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.

** Help changes

114
+++
115 116 117 118 119 120
*** `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.

121
---
122 123 124 125
*** `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).

126 127 128 129
** Minibuffer changes
---
*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
next and previous path separator, respectively.
130
+++
131 132 133
*** minibuffer-electric-default-mode can rewrite (default ...) to [...].
Just set minibuffer-eldef-shorten-default to t before enabling the mode.

134 135 136
** 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
137
automatically at startup, or when customizing an imagemagick- option.
138
+++
139
*** Setting `imagemagick-types-inhibit' to t now disables the use of
140 141
ImageMagick to view images.  You must call imagemagick-register-types
afterwards if you do not use customize to change this.
142
+++
143
*** The new variable `imagemagick-enabled-types' also affects which
144 145 146
ImageMagick types are treated as images.  The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.
147
---
148 149
*** Images displayed via ImageMagick now support transparency and the
:background image spec property.

This minor mode replaces `toggle-read-only', which is now obsolete.

** Emacs now generates backtraces on fatal errors.
On encountering a fatal error, Emacs now outputs a textual description
of the fatal signal, and a short backtrace on platforms like glibc
that support backtraces.

*** Non-regexp Isearch now performs "lax" space matching.
Each sequence of spaces in the supplied search string may match any
sequence of one or more whitespace characters, as specified by the
variable `search-whitespace-regexp'.  (This variable is also used by a
similar existing feature for regexp Isearch).

*** New option `replace-lax-whitespace'.
If non-nil, `query-replace' uses flexible whitespace matching too.
The default is nil.
232
+++
233 234 235 236
*** 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.

237 238 239 240 241 242 243 244 245 246 247 248 249 250
+++
** `C-x 8 RET' is now bound to `insert-char', which is now a command.
`ucs-insert' is now an obsolete alias for `insert-char'.

---
** The `z' key no longer has a binding in most special modes.
It used to be bound to `kill-this-buffer', but `z' is too easy to
accidentally type.

+++
** New option `delete-trailing-lines' specifies whether
M-x delete-trailing-whitespace should delete trailing lines at the end
of the buffer.  It defaults to t.

305
*** CL's main entry is now (require 'cl-lib).
306
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
307 308
i.e. all its definitions have the "cl-" prefix (and internal definitions use
the "cl--" prefix).
309 310 311 312 313 314

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'.

Glenn Morris's avatar
Glenn Morris committed
315 316
The old `cl' is now deprecated and is mainly just a bunch of aliases that
provide the old non-prefixed names.  Some exceptions are listed below.
317

318
+++
319 320 321
*** `cl-flet' is not like `flet' (which is deprecated).
Instead it obeys the behavior of Common-Lisp's `flet'.

322
+++
323 324 325 326 327
*** `cl-labels' is slightly different from `labels'.
The difference is that it relies on the `lexical-binding' machinery (as opposed
to the `lexical-let' machinery used previously) to capture definitions in
closures, so such closures will only work if `lexical-binding' is in use.

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.

** Python mode

A new version of python.el, which provides several new features, including:
481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532
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.

*** 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.

693 694
** set-buffer-multibyte now signals an error in narrowed buffers.

695
+++
696 697 698 699 700
** (random) by default now returns a different random sequence in
every Emacs run.  Use (random S), where S is a string, to set the
random seed to a value based on S, in order to get a repeatable
sequence in later calls.

701
---
702 703 704 705
** The function `x-select-font' can return a font spec, instead of a
font name as a string.  Whether it returns a font spec or a font name
depends on the graphical library.

706
+++
707 708 709 710
** If the NEWTEXT arg to `replace-match' contains a substring "\?",
that substring is inserted literally even if the LITERAL arg is
non-nil, instead of causing an error to be signaled.

711 712 713 714 715 716
+++
** 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'.

717 718 719 720 721 722
+++
** 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.

723
---
724 725 726
** `face-spec-set' no longer sets frame-specific attributes when the
third argument is a frame (that usage was obsolete since Emacs 22.2).

727 728 729 730 731
+++
** 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.

732 733 734 735 736 737 738
+++
** The CL package's `get-setf-method' function no longer exists.
Generalized variables are now part of core Emacs Lisp, and implemented
differently to the way cl.el used to do it.  It is not possible to
define a compatible replacement for `get-setf-method'.  See the file
gv.el for internal details of the new implementation.

739 740 741 742
** Spelling changes.
Some Lisp symbols have been renamed to avoid problems with spelling
that is incorrect or inconsistent with how Emacs normally spells a word.

** Floating point functions now always return special values like NaN,
instead of signaling errors, if given invalid args, e.g. (log -1.0).
Previously, they returned NaNs on some platforms but signaled errors
on others.  The affected functions are acos, asin, tan, exp, expt,
log, log10, sqrt, and mod.

** Interpreted files are eagerly macro-expanded during load.
This can significantly speed up execution of non-byte-compiled code,
but can also bump into harmless and previously unnoticed cyclic
dependencies.  These should not be fatal: they will simply cause the
macro-calls to be left for later expansion (as before), but will also
923 924
result in a warning ("Eager macro-expansion skipped due to cycle")
describing the cycle.
