* 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.

125 126 127 128 129
** The blink cursor stops blinking after 10 blinks (default) on X and NS.
You can change the default by customizing the variable blink-cursor-blinks.
Also timers for blinking are stopped when no blinking is done, so Emacs does
not consume CPU cycles.

* Editing Changes in Emacs 24.4
132

133 134 135 136 137
** `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.

138 139
** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
140

141 142 143
** In keymaps where SPC scrolls, S-SPC now scrolls in the reverse direction.
Eg View mode, etc.

144 145 146 147 148 149 150
+++
** 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.

151 152
** New command `kmacro-to-register' to store keyboard macros in registers.

153 154 155 156 157
** 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
160

161 162 163 164 165 166 167 168 169 170 171 172
** `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'.

176 177 178 179 180 181
** `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.

*** All delphi-* variables and functions have been renamed to opascal-*.
Juanma Barranquero's avatar

207 208
*** `delphi-newline-always-indents' is not supported any more.
Use `electric-indent-mode' instead.
209 210
*** `delphi-tab' is gone, replaced by `indent-for-tab-command'.

211 212
** Eldoc Mode works properly in the minibuffer.

213 214
** jit-lock-debug-mode lets you use the debuggers on code run via jit-lock.

215 216 217
** completing-read-multiple's separator can now be a regexp.
The default separator is changed to allow surrounding spaces around the comma.

218 219 220 221
** Battery

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

222 223 224 225

229
*** New variable `diary-from-outlook-function', used by the command
230 231
`diary-from-outlook'.

232 233 234 235 236 237 238
** cl-lib

*** New macro cl-tagbody.

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

239 240 241 242 243 244 245 246 247 248 249 250 251 252
** 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.

253 254
*** Support for ISO 8601 dates.

255 256 257 258 259
** Desktop

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

260 261 262 263
*** `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.
264

265 266 267 268
** Dired

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

269 270 271 272 273 274
** 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.

275 276 277

288
** Image mode
289 290 291 292 293

*** 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.

294 295 296 297
*** 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.

298 299 300 301 302 303
---
*** 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.

304 305 306 307 308 309
** 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'.

310 311 312 313 314 315 316 317 318 319
** 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.

320
** Search and Replace
321

322 323 324 325
*** 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.

326 327 328
*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
and adds it to the search string.

329 330 331
*** `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).
332

333 334 335
*** `query-replace' skips invisible text when `search-invisible' is nil,
and opens overlays with hidden text when `search-invisible' is `open'.

336 337 338 339
+++
*** By default, prefix arguments do not now terminate Isearch mode.
Set `isearch-allow-prefix' to nil to restore old behavior.

340 341 342 343
*** More Isearch commands accept prefix arguments, namely
`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
`isearch-yank-line'.

344 345 346 347 348 349 350 351
*** 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.

363 364 365
+++
** New function `ses-rename-cell' to give SES cells arbitrary names.

366 367 368 369 370 371 372 373 374
** 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.

375 376
** 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)
377 378
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
379 380
When its arg KEEP-BLANKS is non-nil (when called interactively with
C-u C-u C-u), duplicate blank lines are preserved.
381

382 383 384 385 386
** 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.

387 388 389 390 391
** 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
392
- cross-category lists of items filtered by specific criteria;
393 394 395 396 397 398 399 400 401 402 403 404 405
- 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.

406
** Tramp
407

408 409
+++
*** New connection method "adb", which allows to access Android
410 411
devices by the Android Debug Bridge.  The variable `tramp-adb-program'
can be used to adapt the path of the "adb" program, if needed.
412

413 414 415 416
*** 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.
417

418 419 420

*** Handlers for `file-acl' and `set-file-acl' for remote machines
which support POSIX ACLs.
421

** Shell

*** `explicit-bash-args' now always defaults to use --noediting.
During initialization, Emacs no longer expends a process to decide
whether it is safe to use Bash's --noediting option.  These days
--noediting is ubiquitous; it was introduced in 1996 in Bash version 2.

* Incompatible Lisp Changes in Emacs 24.4
495

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

499 500 501 502
** 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.

** `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/...

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

519 520 521 522
** frame-local variables that affect redisplay do not work any more.
More specifically, the redisplay does not bother to check for a frame-local
value when looking up variables.

523 524 525 526
** nil and "unbound" are indistinguishable in symbol-function.
`symbol-function' never signals `void-function' any more.

** The return value of `backup-buffer' has changed.
The second argument is no longer an SELinux context, instead it is an

`file-extended-attributes'.  The attributes can be applied to another
file using `set-file-extended-attributes'.

* Lisp Changes in Emacs 24.4
545

546 547
** New hook `tty-setup-hook'.

548 549 550
+++
** New macro with-eval-after-load.  Like eval-after-load, but better behaved.

551
** Obsoleted functions:
552
*** `log10'
553 554 555 556
*** `dont-compile'
*** `lisp-complete-symbol'
*** `field-complete'
*** `minibuffer-completion-contents'
557 558
*** `isearch-nonincremental-exit-minibuffer'
*** `isearch-filter-visible'
559
*** `generic-make-keywords-list'
560

561 562 563 564 565 566
** `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'.

567 568 569
** `split-string' now takes an optional argument TRIM.
The value, if non-nil, is a regexp that specifies what to trim from
the start and end of each substring.
570

571 572
** `get-upcase-table' is obsoleted by the new `case-table-get-table'.

573 574 575
** Support for filesystem notifications.
Emacs now supports notifications of filesystem changes, such as
creation, modification, and deletion of files.  This requires the
576 577 578
`glib' API, or the 'inotify' API (on GNU/Linux systems only).  On
MS-Windows systems, this is supported for Windows XP and newer
versions.
579

580 581 582 583 584 585 586 587 588 589 590 591 592 593
** 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.

594 595
** Face changes

Juanma Barranquero's avatar
Juanma Barranquero committed
596
*** The function `face-spec-set' is now analogous to `setq' for face specs.
597 598 599 600 601 602 603
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).

604 605 606
*** New face characteristic (supports :underline (:style wave))
specifies whether or not the terminal can display a wavy line.

607 608 609 610 611 612 613 614 615 616 617 618 619 620 621
** 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.

622 623 624 625 626 627 628 629 630 631 632 633 634 635 636 637 638 639 640 641 642 643 644 645 646 647 648 649 650
** 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'.

654
** time-to-seconds is not obsolete any more.
655
** New function special-form-p.
656 657 658
** Docstrings can be made dynamic by adding a `dynamic-docstring-function'
text-property on the first char.

659 660 661
** The `defalias-fset-function' property lets you catch calls to defalias
and redirect them to your own function instead of `fset'.

662
** The lock for 'DIR/FILE' is now 'DIR/.#FILE' and may be a regular file.
663 664 665 666 667 668 669
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.

670 671
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.
672

673 674 675 676 677 678 679 680 681 682 683
** 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'.

684 685 686 687
** The 6th argument to `copy-file' has been renamed to
`preserve-extended-attributes' as it now handles both SELinux context
and ACL entries.

688 689 690
** Changes to the Emacs Lisp Coding Conventions in Emacs 24.4

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

** 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.)

716 717 718 719 720
+++
** 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.

721 722 723 724 725 726
+++
** 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.

727 728 729 730 731 732 733
---
** 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.

*** 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 (and internal definitions
use 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 `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
Glenn Morris's avatar

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.
992 993

*** `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'.
1000 1001
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.

** 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':
1049
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-while -> python-skeleton-while
**** python-find-function -> python-nav-jump-to-defun

**** 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
