* Installation Changes in Emacs 24.4
25

26
** Emacs can be compiled with ACL support.
27 28
This happens by default if a suitable support library is found at
build time, like libacl on GNU/Linux.  To prevent this, use the
29
configure option `--disable-acl'.
30

31
** Emacs can be compiled with file notification support.
32 33 34 35
This happens by default if a suitable system library is found at
build time.  To prevent this, use the configure option
`--with-file-notification-no'.  See below for file-notify features.
FIXME?  This feature is not available for the Nextstep port. (?)
36

37
** The configure option --with-crt-dir has been removed.
38 39 40
It is no longer needed, as the crt*.o files are no longer linked
specially.

41 42 43
** Directories passed to configure option `--enable-locallisppath' are
no longer created during installation.

44 45 46 47
---
** Emacs for NS (OSX, GNUStep) can be built with ImageMagick support.
pkg-config is required to find ImageMagick libraries.

* Changes in Emacs 24.4
53

54 55
** Key ? also describes prefix bindings like C-h.

56 57 58 59 60 61 62
+++
** `apropos-variable' is now `apropos-user-option'
`apropos-user-option' shows all user options while `apropos-variable'
shows all variables.  When called with a universal prefix argument,
the two commands swap their behaviors.  When `apropos-do-all' is
non-nil, they output the same results.

63 64 65 66
+++
** `eval-defun' on an already defined defcustom calls the :set function,
if there is one.

67 68 69 70
** If the new variable `enable-dir-local-variables' is nil,
directory local variables are ignored.  May be useful for some modes
that want to ignore directory-locals while still respecting file-locals.

71 72 73 74
** The option `set-mark-default-inactive' has been deleted.
This unfinished feature was introduced by accident in Emacs 23.1;
simply disabling Transient Mark mode does the same thing.

75 76 77
** `initial-buffer-choice' can now specify a function to set up the
initial buffer.

78 79 80 81 82 83 84 85
** `remember-notes' creates a buffer whose content is saved on kill-emacs.
You may think of it as a *scratch* buffer whose content is preserved.
In fact, it was designed as a replacement for *scratch* buffer and can
be used that way by setting `initial-buffer-choice' to `remember-notes'
and `remember-notes-buffer-name' to "*scratch*".  Without the second
change, *scratch* buffer will still be there for notes that do not
need to be preserved.

86 87
** `write-region-inhibit-fsync' now defaults to t in batch mode.

88 89 90 91 92
** ACL support has been added.
+++
*** Emacs preserves the ACL entries of files when backing up.
+++
*** New functions `file-acl' and `set-file-acl' get and set the ACL
93 94 95
entries of a file.  On GNU/Linux, the POSIX ACL interface is used via
libacl.  On MS-Windows, the NT Security APIs are used to emulate the
POSIX ACL interfaces.
96

97
** New option `scroll-bar-adjust-thumb-portion'.
98 99 100
Available only on X, this option allows to control over-scrolling
using the scroll bar (i.e. dragging the thumb down even when the end
of the buffer is visible).
101

102 103 104
** New function `add-face-text-property' has been added, which can be
used to conveniently prepend/append new face attributes to text.

105 106
** In compiled Lisp files, the header no longer includes a timestamp.

107 108 109 110 111 112
** Multi-monitor support has been added.

*** New functions `display-monitor-attributes-list' and
`frame-monitor-attributes' can be used to obtain information about
each physical monitor on multi-monitor setups.

113 114 115 116 117 118 119 120
*** The functions `display-pixel-width' and `display-pixel-height' now
behave consistently among the platforms: they return the pixel width
or height for all physical monitors associated with the given display
as just they were on X11.  To get information for each physical
monitor, use the new functions above.  Similar notes also apply to
`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.

121 122 123 124
** New macro `alternatives-define' can be used to define generic commands.
Generic commands are interactive functions whose implementation can be
selected among several alternatives, as a matter of user preference.

* Editing Changes in Emacs 24.4
127

128 129 130 131 132
** `split-window' is no longer a command, just a non-interactive function.
As a command it was a special case of `split-window-below', and as such
superfluous.  After being reimplemented in Lisp, its interactive form
was mistakenly retained.

133 134
** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
135

136 137 138
** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction.
Eg View mode, etc.

139 140 141 142 143 144 145
+++
** New option `visual-order-cursor-movement'.
If this is non-nil, cursor motion with arrow keys will follow the
visual order of characters on the screen: <left> always moves to the
left, <right> always moves to the right, disregarding the surrounding
bidirectional context.

146 147
** New command `kmacro-to-register' to store keyboard macros in registers.

148 149 150 151 152
** Shell Script mode

*** `sh-mode' now has the mode own `add-log-current-defun-function'.
You can pick the name of the function and the variables with `C-x 4 a'.

* Changes in Specialized Modes and Packages in Emacs 24.4
155

156 157 158 159 160 161 162 163 164 165 166 167
** `eshell' now supports visual subcommands and options
Eshell has been able to handle "visual" commands (interactive,
non-line oriented commands such as top that require display
capabilities not provided by eshell) by running them in an Emacs
terminal emulator.  See `eshell-visual-commands'.

This feature has been extended to subcommands and options that make a
usually line-oriented command a visual command.  Typical examples are
"git log" and "git <command> --help" which display their output in a
pager by default.  See `eshell-visual-subcommands' and
`eshell-visual-options'.

** If your Emacs is compiled with libxml2 support, you can use the new
built-in web browser `eww'.

171 172 173 174 175 176
** `remember' can now store notes in separates files
You can use the new function `remember-store-in-files' within the
`remember-handler-functions' option.

See `remember-data-directory' and `remember-directory-file-name-format'
for new options related to this function.
177 178

** `ido-use-virtual-buffers' takes a new value 'auto.
179 180
** `ido-decorations' has been slightly extended to give a bit more control.

*** All delphi-* variables and functions have been renamed to opascal-*.
Juanma Barranquero's avatar
Juanma Barranquero committed
205 206
*** `delphi-newline-always-indents' is not supported any more.
Use `electric-indent-mode' instead.
207 208
*** `delphi-tab' is gone, replaced by `indent-for-tab-command'.

209 210
** Eldoc Mode works properly in the minibuffer.

211 212
** jit-lock-debug-mode lets you use the debuggers on code run via jit-lock.

213 214 215
** completing-read-multiple's separator can now be a regexp.
The default separator is changed to allow surrounding spaces around the comma.

216 217 218 219
** Battery

*** Battery information via the BSD `apm' utility is now supported.

220 221 222 223
** Buffer Menu

*** `M-s a C-o' shows lines matching a regexp in marked buffers using Occur.

224 225 226
** Calendar and Diary

+++

227
*** New variable `diary-from-outlook-function', used by the command
228 229
`diary-from-outlook'.

230 231 232 233 234 235 236
** cl-lib

*** New macro cl-tagbody.

+++
*** letf is now just an alias for cl-letf.

237 238 239 240 241 242 243 244 245 246 247 248 249 250
** Calc

*** Calc by default now uses the Gregorian calendar for all dates, and
uses January 1, 1 AD as its day number 1.  Previously Calc used the
Julian calendar for dates before September 14, 1752, and it used
December 31, 1 BC as its day number 1; the new scheme is more
consistent with Calendar's calendrical system and day numbering.

*** The new variable `calc-gregorian-switch' lets you configure the
date when Calc switches from the Julian to the Gregorian calendar.
Nil, the default value, means to always use the Gregorian calendar.
The value (YEAR MONTH DAY) means to start using the Gregorian calendar
on the given date.

251 252
*** Support for ISO 8601 dates.

253 254 255 256 257
** Desktop

*** `desktop-auto-save-timeout' defines the number of seconds between
auto-saves of the desktop.

258 259 260 261
*** `desktop-restore-frames', enabled by default, allows saving and
restoring the window/frame configuration.  Additional options
`desktop-restore-in-current-display' and
`desktop-restoring-reuses-frames' allow further customization.
262

263 264 265 266
** Dired

*** New minor mode `dired-hide-details-mode' hides details.

267 268 269 270 271 272
** ERC

*** New option `erc-accidental-paste-threshold-seconds'.
If set to a number, this can be used to avoid accidentally paste large
amounts of data into the ERC input.

273 274 275
---
** New F90 mode option `f90-smart-end-names'.

276
** Icomplete is a bit more like Ido.
277 278 279 280
*** key bindings to navigate through and select the completions.
*** The icomplete-separator is customizable, and its default has changed.
*** Removed icomplete-show-key-bindings.

281
** Image mode
282 283 284 285 286

*** New commands `n' (`image-next-file') and `p' (`image-previous-file')
visit the next image file and the previous image file in the same
directory, respectively.

287 288 289 290
*** New commands to show specific frames of multi-frame images.
`f' (`image-next-frame') and `b' (`image-previous-frame') visit the
next or previous frame.  `F' (`image-goto-frame') shows a specific frame.

291 292 293 294 295 296
---
*** The command `image-mode-fit-frame' deletes other windows.
When toggling, it restores the frame's previous window configuration.
It also has an optional frame argument, which can be used by Lisp
callers to fit the image to a frame other than the selected frame.

297 298 299 300 301 302
** Info

*** New face `info-index-match' is used to highlight matches in index
entries displayed by `Info-index-next', `Info-virtual-index' and
`info-apropos'.

303 304 305 306 307 308 309 310 311 312
** Hi-Lock

*** New option `hi-lock-auto-select-face'.  When non-nil, hi-lock commands
will cycle through faces in `hi-lock-face-defaults' without prompting.

+++
*** New global command `M-s h .' (`highlight-symbol-at-point')
highlights the symbol found near point without prompting,
using the next face automatically.

313
** Search and Replace
314

315 316 317 318
*** New global command `M-s .' (`isearch-forward-symbol-at-point')
starts a symbol (identifier) incremental search forward with the
symbol found near point added to the search string initially.

319 320 321
*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
and adds it to the search string.

322 323 324
*** `M-s i' in Isearch mode toggles the variable `isearch-invisible'
between nil and the value of the option `search-invisible' (or `open'
when it's nil).
325

326 327 328
*** `query-replace' skips invisible text when `search-invisible' is nil,
and opens overlays with hidden text when `search-invisible' is `open'.

329 330 331 332
+++
*** By default, prefix arguments do not now terminate Isearch mode.
Set `isearch-allow-prefix' to nil to restore old behavior.

333 334 335 336
*** More Isearch commands accept prefix arguments, namely
`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
`isearch-yank-line'.

337 338 339 340 341 342 343 344
*** Word search now matches whitespace at the beginning/end
of the search string if it contains leading/trailing whitespace.
In an incremental word search or when using a non-nil LAX argument
of `word-search-regexp', the lax matching can also match part of
the first word (in addition to the lax matching of the last word).
The same rules are now applied to the symbol search with the difference
that it matches symbols, and non-symbol characters between symbols.

** The unrmail command converts from BABYL to mboxrd rather than mboxo.
Customize `unrmail-mbox-format' to change this.

---
** Similarly, customize `rmail-mbox-format' to influence some minor aspects
of how Rmail displays non-MIME messages.

356 357 358
+++
** New function `ses-rename-cell' to give SES cells arbitrary names.

359 360 361 362 363 364 365 366 367
** trace-function was largely rewritten.
New features include:
- no prompting for the destination buffer, unless a prefix-arg was used.
- additionally to prompting for a destination buffer, when a prefix-arg is
  used, the user can enter a "context", i.e. Lisp expression whose value at the
  time the function is entered/exited will be printed along with the function
  name and arguments.  Useful to trace the value of (current-buffer) or
  (point) when the function is invoked.

368 369
** New command `delete-duplicate-lines' has new types of operation:
When its arg ADJACENT is non-nil (when called interactively with C-u C-u)
370 371
it works like the utility `uniq'.  Otherwise by default it deletes
duplicate lines everywhere in the region without regard to adjacency.
Juanma Barranquero's avatar
Juanma Barranquero committed
372 373
When its arg KEEP-BLANKS is non-nil (when called interactively with
C-u C-u C-u), duplicate blank lines are preserved.
374

375 376 377 378 379
** New `cycle-spacing' command allows cycling between having just one
space, no spaces, or reverting to the original spacing.  Like
`just-one-space' command it can handle or ignore newlines and
leave different number of spaces.

380 381 382 383 384
** Todo mode has been rewritten and enhanced.
New features include:
- support for multiple todo files and archive files of done items;
- renaming, reordering, moving, merging, and deleting categories;
- sortable tabular summaries of categories and the types of items they contain;
Paul Eggert's avatar
Paul Eggert committed
385
- cross-category lists of items filtered by specific criteria;
386 387 388 389 390 391 392 393 394 395 396 397 398
- more fine-grained interaction with the Emacs diary, by being able to decide
  for each todo item whether it appears in the Fancy Diary display;
- highly flexible new item insertion and item editing;
- moving items between categories, storing done items in their category or in
  archive files, undoing or unarchiving done items;
- reprioritizing items by inputting a numerical priority;
- extensive customizability of operation and display, including numerous faces.
To support some of these features, a new file format is used, which is
incompatible with the old format; however, you can convert old todo and done
item files to the new format on initializing the first new todo file, or at any
later time with the provided conversion command.  The old version of
todo-mode.el has been made obsolete and renamed otodo-mode.el.

399
** Tramp
400

401 402
+++
*** New connection method "adb", which allows to access Android
403 404
devices by the Android Debug Bridge.  The variable `tramp-adb-program'
can be used to adapt the path of the "adb" program, if needed.
405

406 407 408 409
*** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2",
"scpc" and "rsyncc" are discontinued.  The ssh option
"ControlMaster=auto" is set automatically in all ssh-based methods,
when possible.

** New `superword-mode' in subword.el
`superword-mode' overrides the default word motion commands to treat
symbol_words as a single word, similar to what `subword-mode' does and
using the same internal functions.

467 468 469 470 471 472 473
** New nadvice.el package offering lighter-weight advice facilities.
It is layered as:
- add-function/remove-function which can be used to add/remove code on any
  function-carrying place, such as process-filters or `<foo>-function' hooks.
- advice-add/advice-remove to add/remove a piece of advice on a named function,
  much like `defadvice' does.

* Incompatible Lisp Changes in Emacs 24.4
480

481 482 483
** The syntax of ?» and ?« is now punctuation instead of matched parens.
Some languages match those as »...« and others as «...» so better stay neutral.

484 485 486 487
** The default file coding for Emacs Lisp files is now utf-8.
(See file-coding-system-alist.)  In most cases, this change is transparent, but
files that contain unusual characters without specifying an explicit coding
system may fail to load with obscure errors.
Xue Fuqiao's avatar
Xue Fuqiao committed
488
You should either convert them to utf-8 or add an explicit `coding:' cookie.
489

490 491 492 493
** overriding-terminal-local-map does not replace the local keymaps any more.
It used to disable the minor mode, major mode, and text-property keymaps,
whereas now it simply has higher precedence.

494
** Default process filters and sentinels are not nil any more.
495 496
Instead they default to a function which does what the nil value used to do.

497 498 499 500 501
** `read-event' does not return decoded chars in ttys any more.
Just as was the case in Emacs-22 and before, decoding of tty input according to
keyboard-coding-system is not performed in read-event any more.  But contrary
to that past, it is still done before input-decode-map/function-key-map/...

502 503
** Removed inhibit-local-menu-bar-menus.

504 505 506 507
** frame-local variables that affect redisplay do not work any more.

value when looking up variables.

** nil and "unbound" are indistinguishable in symbol-function.
`symbol-function' never signals `void-function' any more.
`fboundp' returns non-nil if the symbol was `fset' to nil.

VAR was bound to nil which was not tremendously useful and just lead to
spurious warnings about an unused var.

519 520 521 522 523 524
** The return value of `backup-buffer' has changed.
The second argument is no longer an SELinux context, instead it is an
alist of extended attributes as returned by the new function
`file-extended-attributes'.  The attributes can be applied to another
file using `set-file-extended-attributes'.

* Lisp Changes in Emacs 24.4

531 532
** New hook `tty-setup-hook'.

533 534 535
+++
** New macro with-eval-after-load.  Like eval-after-load, but better behaved.

536
** Obsoleted functions:
537
*** `log10'
538 539 540 541
*** `dont-compile'
*** `lisp-complete-symbol'
*** `field-complete'
*** `minibuffer-completion-contents'
542 543

*** `isearch-filter-visible'
544
*** `generic-make-keywords-list'
545

546 547 548 549 550 551 552
** `with-wrapper-hook' is obsoleted by `add-function'.
The few hooks that used with-wrapper-hook are replaced as follows:
*** `abbrev-expand-function' obsoletes `abbrev-expand-functions'.
*** `completion-in-region-function' obsoletes `completion-in-region-functions'.
*** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'.


553 554
** `get-upcase-table' is obsoleted by the new `case-table-get-table'.

555 556 557
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files.  This requires the
558 559 560
`glib' API, or the 'inotify' API (on GNU/Linux systems only).  On
MS-Windows systems, this is supported for Windows XP and newer
versions.
561

562 563 564 565 566 567 568 569 570 571 572 573 574 575
** Changes in autorevert.el

---
*** If Emacs is compiled with file notification support, notifications
are used instead of checking the time stamp of the files.  You can
disable this by setting the user option `auto-revert-use-notify' to
nil.  Alternatively, a regular expression of directories to be
excluded from file notifications can be specified by
`auto-revert-notify-exclude-dir-regexp'.

---
*** The new user option `auto-revert-remote-files' enables reversion
of remote files when set to non-nil.

576 577
** Face changes

Juanma Barranquero's avatar

578
*** The function `face-spec-set' is now analogous to `setq' for face specs.
579 580 581 582 583 584 585
Its third arg now accepts values specifying exactly which face spec to
set (defface, custom, or user spec), and it directly sets the relevant
property using the supplied face spec.

*** Face specs set via Custom themes now replace the `defface' spec
rather than inheriting from it (as do face specs set via Customize).

586 587 588
*** New face characteristic (supports :underline (:style wave))
specifies whether or not the terminal can display a wavy line.

589 590 591 592 593 594 595 596 597 598 599 600 601 602 603
** Image API

+++
*** `image-animated-p' is now `image-multi-frame-p'.
It returns non-nil for any image that contains multiple frames,
whether or not it specifies a frame delay.

+++
*** When animating images that do not specify a frame delay,
Emacs uses `image-default-frame-delay'.

+++
*** New functions `image-current-frame' and `image-show-frame' for getting
and setting the current frame of a multi-frame image.

604 605 606 607 608 609 610 611 612 613 614 615 616 617 618 619 620 621 622 623 624 625 626 627 628 629 630 631 632
** Changes in encoding and decoding of text

---
*** New coding-system `prefer-utf-8'.
This is like `undecided' but prefers UTF-8 on decoding if the text to
be decoded does not contain any invalid UTF-8 sequences.  On encoding,
any non-ASCII characters are automatically encoded as UTF-8.

---
*** New attributes of coding-systems whose type is `undecided'.
Two new attributes, `:inhibit-null-byte-detection' and
`:inhibit-iso-escape-detection', determine how to detect encoding of
text that includes null bytes and ISO-2022 escape sequences,
respectively.  Each of these attributes can be either nil, zero, or
t.  If it is t, decoding text ignores null bytes and, respectively,
ISO-2022 sequences.  If it is nil, null bytes cause text to be decoded
with no-conversion and ISO-2022 sequences cause Emacs to assume the
text is encoded in one of the ISO-2022 encodings, such as
iso-2022-7bit.  If the value is zero, Emacs consults the variables
inhibit-null-byte-detection and inhibit-iso-escape-detection, which
see.
The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer
UTF-8 encoding and decoding, whenever possible.

These attributes are only meaningful for coding-systems of type
`undecided'.  (The type of a coding-system is determined by its
`:coding-type' attribute and can be accessed by calling the
`coding-system-type' function.)

** The function `set-visited-file-modtime' now accepts a 0 or -1 argument
with the same interpretation as the returned value of `visited-file-modtime'.

636
** time-to-seconds is not obsolete any more.
637
** New function special-form-p.
638 639 640
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
text-property on the first char.

641 642 643
** The `defalias-fset-function' property lets you catch calls to defalias
and redirect them to your own function instead of `fset'.

644
** The lock for 'DIR/FILE' is now 'DIR/.#FILE' and may be a regular file.
645 646 647 648 649 650 651
When you edit DIR/FILE, Emacs normally creates a symbolic link
DIR/.#FILE as a lock that warns other instances of Emacs that DIR/FILE
is being edited.  Formerly, if there was already a non-symlink file
named DIR/.#FILE, Emacs fell back on the lock names DIR/.#FILE.0
through DIR/.#FILE.9.  These fallbacks have been removed, so that
Emacs now no longer locks DIR/FILE in that case.

652 653
On file systems that do not support symbolic links, the lock is now a
regular file with contents being what would have been in the symlink.
654

655 656 657 658 659 660 661 662 663 664 665
** The 9th element returned by `file-attributes' is now unspecified.
Formerly, it was t if the file's gid would change if file were deleted
and recreated.  This value has been inaccurate for years on many
platforms, and nobody seems to have noticed or cared.

** The function `file-ownership-preserved-p' now has an optional
argument GROUP which causes it check for file group too.  This can be
used in place of the 9th element of `file-attributes'.

** New functions `group-gid' and `group-real-gid'.

666 667 668 669
** The 6th argument to `copy-file' has been renamed to
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.

670 671 672
** Changes to the Emacs Lisp Coding Conventions in Emacs 24.4

*** The package descriptor and name of global variables, constants,

* Changes in Emacs 24.4 on Non-Free Operating Systems
678

** Emacs for MS-Windows can now be built by running the configure script
using the MSYS environment and MinGW development tools.
This is from now on the preferred method of building Emacs on
MS-Windows.  The Windows-specific configure.bat and makefile.w32-in
files are deprecated.  See the file nt/INSTALL.MSYS for detailed
instructions.

Using the Posix configure script and Makefile's also means a change in
the directory structure of the Emacs installation on Windows.  It is
now the same as on GNU and Unix systems.  In particular, the auxiliary
programs, such as cmdproxy.exe and hexl.exe, are in
libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs
version), version-independent site-lisp is in share/emacs/site-lisp,
version-specific Lisp files are in share/emacs/VERSION/lisp and in
share/emacs/VERSION/site-lisp, Info docs are in share/info, and data
files are in share/emacs/VERSION/etc.  (Emacs knows about all these
directories and will find the files in there automatically; there's no
need to set any variables due to this change.)

698 699 700 701 702
+++
** The "generate a backtrace on fatal error" feature now works on MS Windows.
The backtrace is written to the 'emacs_backtrace.txt' file in the
directory where Emacs was running.

703 704 705 706 707 708
+++
** The variable `buffer-file-type' is no longer supported.
Setting it has no effect, and %t in the mode-line format is ignored.
Likewise, `file-name-buffer-file-type-alist' is now obsolete, and
modifying it has no effect.

709 710 711 712 713 714 715
---
** Lock files now work on MS-Windows.
This allows to avoid losing your edits if the same file is being
edited in another Emacs session or by another user.  See the node
"Interlocking" in the Emacs User Manual for the details.  To disable
file locking, customize `create-lockfiles' to nil.

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 `cl' definitions that had to use `foo*' to avoid conflicts with
pre-existing Elisp entities.  These have been renamed to `cl-foo'
rather than `cl-foo*'.

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:

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

In particular, in cl-flet function definitions are lexically scoped,
whereas in flet the scoping is dynamic.

*** `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.

*** `cl-letf' is not exactly like `letf'.
982 983
The only difference is in details that relate to some deprecated usage
of `symbol-function' in place forms.

*** `progv' was rewritten to use the `let' machinery.

A side effect is that variables without corresponding values are bound
to nil rather than being made unbound.

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'

** Ediff now uses the same color scheme as Diff mode.

** 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, including (old -> new):
**** 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, including:

**** `python-indent-string-contents': Strings are never indented.

**** `python-honour-comment-indentation':
1031
Comments are always considered as indentation markers.

**** `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 -> new):
**** 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-beginning-of-defun-function -> python-nav-beginning-of-defun
**** python-end-of-defun-function -> python-nav-end-of-defun
**** 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
