** 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

66 67 68 69 70
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.

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

74 75 76 77 78

** 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.

/usr/pkg/lib to the linker search path.  You must add them yourself if
you want them.

** Help changes

129
+++
130 131 132 133 134 135
*** `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.

136
---
137 138 139 140
*** `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).

141 142 143 144 145 146 147 148
** Minibuffer changes
---
*** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the
next and previous path separator, respectively.

*** minibuffer-electric-default-mode can rewrite (default ...) to [...].
Just set minibuffer-eldef-shorten-default to t before enabling the mode.

149 150 151
** 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
152 153
automatically at startup, or when customizing a relevant imagemagick-
option.
154
+++
155
*** Setting `imagemagick-types-inhibit' to t now disables the use of
156 157
ImageMagick to view images.  You must call imagemagick-register-types
afterwards if you do not use customize to change this.
158
+++
159
*** The new variable `imagemagick-enabled-types' also affects which
160 161 162
ImageMagick types are treated as images.  The function
`imagemagick-filter-types' returns the list of types that will be
treated as images.
163
---
164 165
*** 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).

245 246 247
*** New option `replace-lax-whitespace'.
If non-nil, `query-replace' uses flexible whitespace matching too.
The default is nil.
248
+++
249 250 251 252
*** 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.

253 254 255 256 257 258 259 260 261 262 263 264 265 266
+++
** `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.

*** `C-x r +' is now overloaded to invoke `append-to-register.

321
*** CL's main entry is now (require 'cl-lib).
322
`cl-lib' is like the old `cl' except that it uses the namespace cleanly,
323 324
i.e. all its definitions have the "cl-" prefix (and internal definitions use
the "cl--" prefix).
325 326 327 328 329 330

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
331 332
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.
333

334
+++
335 336 337
*** `cl-flet' is not like `flet' (which is deprecated).
Instead it obeys the behavior of Common-Lisp's `flet'.

338
+++
339 340 341 342 343
*** `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.

*** 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'.

** Diff mode

*** Changes are now highlighted using the same color scheme as in
modern VCSes.  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.

** Python mode

A new version of python.el, which provides several new features, including:
490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541
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-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':

*** 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.

** (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.

711 712 713 714
** 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.

715 716 717 718
** 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.

719 720 721 722 723 724
+++
** 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'.

725 726 727 728 729 730
+++
** The return values of `defalias', `defun' and `defmacro' have changed,

defmacro currently return the name of the newly defined function/macro
but this should not be relied upon.

731

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.

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
921 922
result in a warning ("Eager macro-expansion skipped due to cycle")
describing the cycle.
