6 This file presents the changes in recent SXEmacs versions. It
7 primarily documents user-visible (interface) changes, but also
8 includes internal changes of possible interest to the users. When
9 describing new features, we try to also document ways of reverting to
10 the old behavior, where applicable. If you dislike a recent change in
11 how SXEmacs behaves, this file might contain a remedy.
13 Use `C-c C-f' to move to the next equal level of outline, and
14 `C-c C-b' to move to previous equal level. `C-h m' will give more
15 info about the Outline mode. Many commands are also available through
18 Users who would like to know which capabilities have been introduced
19 in each release should look at the appropriate section of this file.
23 * Changes in SXEmacs 22.1.14 (Geo)
24 ==================================
26 We switched to git! And this release cycle was all about updating the
27 build chain, version strings, and docs and whatnot from tla-isms to
30 You can now grab the SXEmacs sources via git with...
32 git clone http://git.sxemacs.org/sxemacs
35 * Changes in SXEmacs 22.1.12 (Fiat)
36 ===================================
38 ** Bugs closed in this release:
40 69, 86, 107, 109, 110, 111, 113, 114, 115, 117, 118, 120
42 ** Build chain fixes and updates -- Ferreira, Freundt, Youngs.
44 *** Fix building without eye-candy (*bars, widgets, etc)
45 *** Begin work on getting SXEmacs built on Arm Linux
46 *** Fix NetBSD 5 build
47 *** Mac OS build fixes
49 ** Source tree reorganisation -- Ferreira.
51 Nelson put a lot of working into reorganising the SXEmacs source tree
52 hierarchy. There are now several subdirectories under `src'...
54 src/database -- has the database code
55 src/ent -- has the "Enhance Number Types" code
56 src/events -- has the "events" code
57 src/media -- has all the multimedia code
58 src/mem -- has memory related code
59 src/mule -- has the MULE stuff
60 src/ui -- has the UI code common to all toolkits
61 src/ui/Gtk -- has the old (non-working) GTK 1 code
62 src/ui/TTY -- has the TTY UI code
63 src/ui/X11 -- has the X11 UI code
64 src/ui/lwlib -- has the Lucid stuff
66 This was done with the view to making maintenance and debugging
67 easier, and also to simplify adding new features.
69 ** FFI improvements, updates, and enhancements -- Zajcev
72 * SXEmacs 22.1.11 was never released.
74 See ChangeLog.d/ChangeLog-22.1.11 for all the changes in the
75 22.1.11 dev cycle, and for why it was not released.
77 * Changes in SXEmacs 22.1.10 (Excalibur)
78 ========================================
80 ** Bugs closed in this release:
82 41, 65, 74, 75, 79, 80, 81, 82, 83, 84, 85, 87, 89, 90, 91, 92, 93,
83 94, 95, 96, 97, 99, 100, 101, 102, 104
85 ** Cool New Sexy Stuff -- Zajcev, Ferreira, Freundt, Youngs.
87 Of course every release must have some cool new stuff. Here's what's
88 new in this release...
90 *** User defined readers
91 *** It's possible to display video in a glyph object in a buffer.
92 *** SXEmacs is now a fairly decent image viewing/manipulation app.
94 There's an undo/redo stack, zoom in/out, rotate, chop/crop, red-eye
95 reduction. There is a whole swag of transformations supported:
96 charcoal, contrast, despeckle, edge, enhance, equalise, gausian blur,
97 negate, normalise, oil painting, radial blur, 3D button effect,
98 sharpen, solarise, and swirl.
100 Who needs The Gimp when you have SXEmacs!
102 *** Added some MacOS icons.
103 *** Support for sqlite3 via FFI
104 *** New way for SXEmacs to handle different file types.
106 It allows you to have #'find-file take different actions based on a
107 predicate. See the new variable `find-file-magic-files-alist'.
109 *** Enable PNG transparent backgrounds
111 Unfortunately this doesn't work if you use a background pixmap.
113 *** FFI callbacks implemented.
114 *** Dbus support via FFI (not completed)
116 This should be considered very much incomplete and experimental. Only
117 rudimentary support is there so far.
119 ** Build chain fixes/improvements -- Burkhardt, Ferreira, Freundt, Youngs.
121 Quite a few build chain related changes were made in this release,
124 *** Work around a bug in GCC 4.5.0
125 *** Powerpc/BSD cpu detection
126 *** A Freedesktop.org compliant sxemacs.desktop file is now installed.
127 *** Updated FFmpeg detection.
128 *** OpenSSL 1.0.0 detection. OpenSSL is no on by default.
129 *** Fix a link error when building with no MPQ
130 *** Fix a minor bison related issue (YYSTYPE)
131 *** Fix building with latest SoX
132 *** Fix --without-x builds
133 *** Fix many C compiler warnings and elisp byte-compiler warnings.
134 *** Fix install for non-FFI and non-Mule builds
135 *** Fix etags build for systems without getopt_long
136 *** Fix (hopefully) parallel builds
137 *** Fix BDWGC-enabled builds
139 ** Minor updates to BDWGC code -- Freundt.
141 ** Catch up with latest ffmpeg API changes -- Freundt.
143 ** Fix for latest ediff -- Ferreira.
145 Changes emacs-internal to escape-quoted.
147 ** Fix for subwindow resizing -- Zajcev.
149 ** Various additions/updates to the contrib directory -- Ferreira
151 ** FFI improvements -- Zajcev
153 ** ENT fixes -- Freundt.
155 ** TTY fixes -- Ferreira.
157 ** Cleaner dump file (less pollution from the build/src dir) -- Freundt, Youngs.
159 ** Improve #'file-basename -- Ferreira
161 It can now take a 2nd arg for extension stripping.
163 ** Misc doc fixes/updates -- Burkhardt, Ferreira, Freundt, Zajcev, Youngs.
165 * Changes in SXEmacs 22.1.9 (Edsel)
166 ===================================
168 ** Bugs closed in this release:
170 32, 33, 34, 35, 36, 37, 38, 39, 40, 42, 45, 46, 47, 48, 49, 50, 51,
171 53, 54, 55, 56, 57, 58, 59, 60, 61, 62
173 See http://issues.sxemacs.org/ for the details.
175 ** Build chain fixes and improvements -- Freundt, Ferreira.
177 Better detection of ALSA, ffmpeg, libffi, libbind, and many other
178 various bits and pieces.
180 General build related fixes were made for MacOS, Solaris, HPUX, and of
183 ** New function, #'mapfam -- Freundt.
185 This new function is an extrememly powerful replacement for _all_ of
186 the current map functions. It not only can do the job of the
187 existing map functions, but can also convert any sequence to any
188 other sequence. Lots of other cool features as well, see its doc
189 string for full details.
191 ** Init file migration code removed -- Youngs.
193 We feel that it is better to NOT mess with other emacsen's set ups.
195 ** Compiler warning fixes -- Freundt.
197 ** PNG images optimised for size -- Burkhardt.
199 All of the PNG images that we ship have been optimised for size.
201 ** Re-work auto-autoloads loading a little -- Ferreira.
203 Priority is given to packages installed under ~/.sxemacs/ and care is
204 taken to eliminate those "foo-autoloads already loaded" warnings.
206 ** Support 256 colour terminals -- Ferreira.
208 Support for 256 colour terminals and colour resolution through
209 approximation for tty devices.
211 ** New FFI util, ffi-magic.el -- Youngs.
213 Uses libmagic to guess file type.
215 ** Cool new stuff in the contrib directory -- Youngs, Ferreira.
217 There are tla hook scripts, build scripts, and build-report scripts.
219 ** New garbage collector BDWGC -- Freundt.
221 SXEmacs can now use the Boehm-Demers-Weiser garbage collector. It is
222 still experimental at this stage and there are known bugs (memory
223 leak). If you have plenty of RAM it is quite usable, and noticably
224 faster than non-BDWGC SXEmacsen. This new feature is not on by
225 default. To get it, configure with --with-experimental-features=all.
227 ** Support for BSD's MP removed -- Freundt.
229 ** Emodule search path/loading fixes -- Youngs.
231 Emodule load path has been made sane. #'load-module and
232 #'locate-module have both been vastly improved and both have
235 ** FFI improvements -- Youngs.
237 The FFI code has been improved so that it can be compatible with
238 XEmacs 21.5 for when they merge our FFI into their code base. Also
239 #'ffi-load and #'ffi-load-library no longer need to be given a file
240 extension as part of the arg to allow for different platforms having
241 different shlib extensions.
243 Also, some UI enhancements were added to ffi-curl.el and
246 ** Etags improvements -- Youngs.
248 A bit of "UI" has been added to etags.el, as well as some code
251 ** Various minor tweaks, fixes, and documentation -- Burkhardt, Ferreira,
252 Freundt, Wallington, Youngs.
255 * Changes in SXEmacs 22.1.8 (Daimler)
256 =====================================
258 ** Bugs closed in this release: 22, 24, 26, 27, 29, 31
260 You might notice a double up of bug numbers here from the previous
261 release. The index got reset and so some bug ID numbers were
264 ** Build chain fixes, improvements -- Freundt, Ferreira, Youngs.
266 We now have a libtool-based build chain.
268 ** Minor improvements to packages bootstrapping -- Youngs.
270 ** User's custom file renamed to custom-${USER}.el -- Youngs.
272 The old variant, custom.el is still used if that file exists.
274 ** Sync XEmacs 21.5's cus-*.el, autoload.el, subr.el -- Youngs.
276 Amongst other things, this sync brings custom-defines, many new custom
277 widgets, and an implementation of the `:inherit' face keyword.
279 ** Skiplist fixes -- Freundt.
281 ** Introduce custom printers -- Zajcev.
283 ** Update GPL licenced stuff to GPL version 3 -- Youngs.
285 ** Add a rc.d inspired init mechanism -- Ferreira.
287 ** Font lock improvements -- Ferreira.
289 ** Byte compile defcustom init values, saving lisp values for correct editing -- Kehoe.
291 Sync from XEmacs 21.5.
293 ** Improve interactivity of custom prompting -- Verna.
295 Sync from XEmacs 21.5.
297 ** Resize echo area when needed -- Aichner, Turnbull, Youngs.
299 Sync from XEmacs 21.5. Don't confuse this with rsz-minibuffer.el in
300 the packages, This is different, the minibuffer and echo area are 2
303 ** #'describe-function (C-h f) prints global keybindings for commands -- Kehoe, Youngs.
305 Sync from XEmacs 21.5.
307 ** New `%b' spec for #'format -- Freundt, Kehoe.
309 This is for converting between ints and bit vectors.
311 ** Sample init file updated -- Youngs.
313 ** Fix the bug exposed by our weak-tests.el -- Youngs.
315 ** Update the man page -- Youngs.
317 ** Support character classes in regexps -- Freundt.
319 ** Misc trivial changes such as doc fixes, typos, etc -- Burkhardt,
320 Freundt, Ferreira, Youngs.
323 * Changes in SXEmacs 22.1.7 (De Lorean)
324 =======================================
326 ** Bugs closed in this release: 13, 20, 21, 24, 25, 27, 28, 31
328 ** Much reworking of the build chain -- Freundt, Ferreira, Youngs.
330 Quite a bit has changed here, a few options have been changed, added,
331 or removed. So if you haven't been following the development it might
332 pay you to have a look at our configure's --help output.
334 ** Fix emodule loading on 64bit machines -- Freundt.
336 ** Security fix in movemail.c (mktemp()->mkstemp()) -- Youngs.
338 ** Etags synched up to upstream 17.32 -- Burkhardt, Youngs.
340 ** Updates/fixes to dllists/skiplists -- Freundt, Ferreira.
342 ** Lots of updates in the ENT area (Enhanced Number Types) -- Freundt.
344 Some stuff has been moved to an external emodule, "ASE" (Algebraic
345 Structures for ENT or "ASE Supersedes ENT"). Also directed graphs
346 have been introduced (sparse representation only so far). And
347 introduce heaps (dense, dynamic, and week).
349 ** cl.el meets C -- Freundt.
351 We've begun work on implementing the common lisp macros as an external
352 emodule. The main focus here is speed, and initial benchmarks are
353 _very_ exciting... The emod version of #'dotimes (#'cl:dotimes) can be
354 nearly 200 times faster than its elisp counterpart!
356 This isn't finished yet, but watch future releases.
358 ** package-suppress mechanism ported from XEmacs 21.5 -- Freundt, Youngs.
360 ** Asynchronous version of #'curl:download added called #'curl:download& -- Freundt.
362 ** Font-lock improvements, especially on TTYs -- Ferreira.
364 ** Fix info search path -- Ferreira.
366 ** Change default setting for progress guages to be off -- Youngs.
368 ** Multimedia updates/fixes -- Freundt, Youngs.
370 Lots of reworking has been done here, especially with PulseAudio,
371 ffmpeg, and threading of the audio jobs etc. Support for gstreamer
372 and xine has been dropped, and libmagic added.
374 ** New macro to define "toggle" variables #'define-toggle-variable -- Zajcev
376 I wouldn't normally list a single new macro in this file, but this one
377 deserves a mention. It sets up toggle variables, including
378 #'turn-on-VAR, #'turn-off-VAR, and #'toggle-VAR. Very nifty.
380 ** Many many compiler warnings have been fixed -- Freundt, Youngs.
382 Almost all byte-compiler warnings have been fixed in our build. And a
383 good deal of the warnings in the C code of a standard build has been
386 ** GC fixes/updates -- Freundt.
388 ** A contrib directory has been added to the tree -- Freundt.
390 So far there are patches in there to pop3.el, smtpmail.el, and
391 starttls.el which takes advantage of some of SXEmacs' cool native
392 features like OpenSSL.
394 Watch this space for more nifty things.
396 ** Minor misc fixes (typos etc) -- Zajcev, Burkhardt, Freundt, Ferreira, Youngs.
398 ** Documentation updates:
399 o sppm.texi -- Burkhardt, Youngs.
400 o lispref.texi -- Freundt, Youngs.
401 o tips.texi -- Freundt.
402 o building.texi -- Youngs.
403 o processes.texi -- Ferreira.
404 o internals.texi -- Freundt.
406 * Changes in SXEmacs 22.1.6 (Cadillac)
407 ======================================
409 ** ENT (Enhanced Number Types) updates and fixes -- Freundt, Ferreira.
411 ** MM (MultiMedia) updates and fixes -- Freundt, Ferreira, Youngs.
413 ** FFi (Foreign Function Interface) updates -- Freundt, Zajcev.
415 ** New ffi-gcrypt.el -- Freundt.
417 ffi-gcrypt.el brings GnuPG's libgcrypt bindings to SXEmacs.
419 ** Line/column numbers in modeline are now padded -- Ferreira.
421 ** New skiplists -- Freundt.
423 This is a basic implementation of Pugh's skip lists. Their efficiency
424 is overwhelming when compared to alists or plists. They also perform
425 better on insertion and removal than large hash-tables (due to the
426 resizing/rehashing which takes place). They can be created almost as
427 fast as lisp lists and thus beat hash-tables there, too.
429 ** Fix module (DSO) load paths -- Youngs.
431 ** SXEmacs maintainer turned 40 -- Mr and Mrs Youngs.
433 This is a recurring bug that was first discovered on June 19th, 1966.
435 ** Test suite updates/improvements -- Turnbull, Youngs.
437 ** Etags updates/fixes -- Ferreira, Youngs.
439 Sync to Francesco's version 17.20 etags. And major surgery on
440 etags.el to make it usable, fixing completion and support for the
443 ** Fix raw string parsing -- Kehoe.
445 A problem that arose in lisp-interaction-mode, where raw strings
446 were parsed as normal strings if you did a C-j after them, becase
447 forward-sexp couldn~t handle them.
449 ** Sync bytecomp-runtime.el with XEmacs 21.5 -- Youngs.
451 The significance of this is that SXEmacs now has all those cool
452 with,if,when,and-boundp macros for clean byte-compiler warning
455 ** OpenSSL updates/fixes/improvements -- Freundt.
457 A rewrite of the old handshake functions. SSL connections can be
458 established as before: open a network-stream, call ossl-ssl-handshake
459 on it and store the result. The new implementation provides also
460 support for certificate authorities (CA), for peer certificates and,
461 using the network-server-streams, secure listening sockets. This will
462 allow to connect/accept to/from servers/clients which require valid
465 ** New PulseAudio support -- Freundt.
467 PulseAudio is the successor to PolypAudio. Because there were so few
468 users using Polyp (think we counted 2 and they're both SXEmacs
469 developers) SXEmacs support for PolypAudio was replaced by PulseAudio
472 ** New Caching compiled regular expressions -- Freundt.
474 All you really need to do to use them is assign them (the regexp) to a
475 variable. Here's an example...
477 (let ((reg1 "^;+\\s-")
479 (while (and (re-search-forward reg1 nil t)
480 (re-search-forward reg2 nil t))
485 (while (and (re-search-forward "^;+\\s-" nil t)
486 (re-search-forward "\\s-+;+" nil t))
489 The former construct will store the compiled regular expressions in the
490 object property list of `reg1' and `reg2' on the first iteration of
491 `while', all following iterations will then use the already compiled
492 regexps. The latter construct will behave as before, the regular
493 expression is compiled and stored, but since the string is hard-coded in
494 the buffer, it will be newly generated (with empty object-plist of
495 course) during every cycle of the while loop.
497 ** Cleaner dump file -- Freundt, Youngs.
499 The portable dump file was getting polluted with things in the
500 packages load-path causing all sorts of undefined and unexpected
501 impossible to track down bugs. No longer!
503 ** Fix many many byte-compiler warnings in building core lisp -- Youngs.
505 ** Fix building without emodules -- Ferreira.
507 ** New Support emodules on MacOS -- Ferreira.
509 ** Fix BerkeleyDB detection on NetBSD -- Ferreira.
511 ** New SXEmacs icons added to dist -- Ferreira.
513 ** Major restructuring of the build chain and install layout -- Freundt.
515 SXEmacs is now pretty much a completely autotool'd project... automake,
516 autoheader, the whole 9 yards. And if that wasn't enough, we are now
517 also, to the best of our knowledge, reasonably FHS-compliant with our
520 The changes to the install directory hierarchies are:
522 now go to... before went to...
523 lisp share/sxemacs-22.1.6/lisp/ lib/sxemacs-22.1.6/lisp/
524 etc share/sxemacs-22.1.6/etc/ lib/sxemacs-22.1.6/etc/
525 info share/info/ lib/sxemacs-22.1.6/info/
526 headers include/sxemacs/22.1.6/ lib/sxemacs-22.1.6/<arch>/include/
528 Packages are now searched for in
530 $prefix/share/sxemacs/{{s,}xemacs,mule,site}-packages/
532 instead of $prefix/lib/sxemacs/.../
534 ** DnD dragged out and dropped on /dev/null -- Freundt.
536 ** Misc build fixes -- Freundt, Ferreira, Youngs.
538 ** Fix `tags' Makefile target -- Youngs.
540 ** Fix bug in `lib-complete' -- Freundt.
542 The bug was causing `find-library' to visit the .elc instead of the
543 .el if you were running SXEmacs in-place from the build tree.
545 ** Fix stack overflow crash in mapconcat -- Ferreira.
547 ** Large update of about.el -- Freundt, Ferreira, Youngs.
549 See: M-x about-sxemacs
551 ** Various documentation updates/fixes/improvements -- Freundt, Ferreira, Youngs.
554 * Changes in SXEmacs 22.1.5 (Bugatti)
555 =====================================
556 First up, this release has turned into a purely maintenance/bugfix
557 release. SXEmacs 22.1.4 had several build-related issues that this
560 ** version.sh fix -- Youngs.
562 Fix a problem with the wrong version being generated.
564 ** Autoconf fixes -- Youngs, Ferreira, Freundt.
566 Lots of changes to the autoconf configure script
568 - Recognise $CFLAGS environment variables
569 - X toolkit autodetection redone
570 - TTY autodetection fixed
571 - PostgreSQL detection properly reported
572 - Change allowed values for menubars, dialogs, widgets
573 menubars -- no athena or motif
576 - Set configure's "bugreport address" to
577 http://issues.sxemacs.org.
578 - Fix gdbm/berkdb detection
579 - Improve libc version detection
581 ** New Makefile target (build-report) -- Kuehl.
583 `make build-report' is a convenience target. It automatically
584 captures make output to files that `M-x build-rpt' knows about. It
585 also runs `make check'. The SXEmacs developers recommend that you use
586 this target to build SXEmacs.
588 ** PROBLEMS updated -- Kuehl, Freundt.
590 Document SELinux/libffi issues and GMP/mpfr Fedora issues.
592 ** pdump/ENT fix for *BSD -- Freundt.
594 ** Documentation updates/fixes -- Youngs, Ferreira, Freundt.
597 * Changes in SXEmacs 22.1.4 (Bentley Turbo)
598 ===========================================
600 ** Many more image formats via FFI/libWand -- Freundt.
602 FFI-enabled SXEmacs can load up libWand and thus display any image
603 format that libWand (ImageMagick) supports.
605 ** Lots of updates to the ENT (Enhanced Number Types) code -- Freundt.
607 ** Mule is on by default -- Youngs.
609 ** Embeddable keyboard macros -- Kuehl.
611 This means that the following sort of thing is possible:
614 C-x ( foo C-x e C-x )
619 ** Default widgets/dialogs to Athena instead of Motif -- Youngs.
621 ** OpenSSL updates -- Freundt.
623 Digest, encryption, and decryption routines that operate on files has
624 been added. Previously this was only available for buffers.
626 ** Build reports have been revamped -- Youngs, Freundt.
628 The SXEmacs build report no longer conflicts with the XEmacs
629 build-report.el. Plus ours also reports on shared lib dependencies
630 and config.h stuff. Sending from Gnus is also supported.
632 ** FFI updates/fixes -- Youngs, Zajcev, Freundt.
634 ** Ability to build postscript, pdf, and html docs -- Ferreira.
636 ** Double linked lists and bloom filters implemented -- Freundt.
638 Bloom filters are a space and time-efficient way to decide about the
639 membership of an element to a given set. Using lisp-lists or vectors,
640 one usually has to traverse the entire list or vector, before
641 membership can be decided. Using hash tables, membership decision is
642 in O(1) (bloom filters also decide in O(1)), but the hash-table's size
643 grows proportionally with the number n of elements, thus its space
644 complexity is O(n), whereas Bloom filters take a constant amount of
645 space regardless how many elements are in it.
647 ** Lightning fast recursive version of directory-files -- Freundt.
649 It's called `directory-files-recur' and in some situations it is even
650 faster than GNU's find(1).
652 ** Portuguese added to etc/HELLO -- Ferreira.
654 ** Massive improvements, enhancements for multimedia (audio) -- Freundt.
656 SXEmacs supports several "sound servers" like: OSS, NAS, ESD, Polypaudio,
657 ALSA, aRts, and Jack. And media streams can be handled by sndfile, ffmpeg,
658 sox, mad, xine, gstreamer. The SXEmacs developers recommend Polyp/ffmpeg
661 And yes, SXEmacs _can_ play mp3 files. :-)
663 ** Autoconf fixes/updates -- Youngs, Freundt.
665 All of the enable/disable options have been converted to with/without
666 options. This allows us to sort them into groups.
668 Also fixes were made to allow building on FreeBSD and NetBSD.
670 ** Big update for the FAQ -- Youngs, Freundt.
672 ** Server Sockets! -- Ferreira.
674 SXEmacs now has server sockets (Yay!). See
675 `open-network-server-stream'.
677 ** Compiler fixes (gcc 2.95) -- Freundt.
679 ** bug-reporter update -- Youngs.
681 `report-sxemacs-bug' now directs people to our BugZilla installation
682 at http://issues.sxemacs.org/
684 ** Documentation updates/fixes/improvements -- Youngs, Ferreira, Freundt.
687 * Changes in SXEmacs 22.1.3 (BMW)
688 =================================
690 ** OpenSSL updates, improvements, and fixes -- Freundt.
692 ** FFI updates, and fixes -- Zajcev.
694 FFI now defaults to "on" if libffi can be found at configure time. It
695 you don't want this, use: `--disable-ffi'.
697 FTP downloads with `curl:download' is working properly now. And with
698 HTTP transfers you can transfer just the HTTP header for a file if you
701 ** Extent/glyph fixes -- Sidwell, Kuehl.
703 ** 32 mouse buttons supported -- Youngs.
705 (global-set-key [(button32)] 'some-function) is valid in SXEmacs.
707 ** Modeline tweaks -- Ferreira.
709 Move line/column number indicators to left side (aka XE 21.5)
711 ** M-x uptime -- Youngs.
713 Every good OS has an uptime util, SXEmacs is no exception. Reports
714 uptime in various formats.
716 ** ia64 build fixes -- Lesjak.
718 ** `C-h n' will no longer find NEWS files from packages -- Youngs.
720 ** List of package mirrors updated -- Aichner, Skyttä.
722 ** Bootstrappable PUI -- Youngs.
724 SXEmacs no longer needs to have _any_ packages pre-installed before
725 PUI can be used. See (Info-goto-node "(sxemacs)Bootstrapping PUI").
727 ** Bignums, and a whole swag of sexy new number goodness -- Freundt.
729 Bignums, bigfloats, and ratios that you may know from XEmacs 21.5 are
730 now in SXEmacs. That and a whole lot more...
732 Features provided when all of the library demands are met:
735 (featurep 'bignum) <=> if MPZ from GMP or BSD MP is present
738 (featurep 'ratio) <=> if MPQ from GMP is present
741 (featurep 'bigfloat) <=> if MPF from GMP is present
743 (featurep 'bigfr) <=> if MPFR is present
745 (featurep 'bigc) <=> if MPC is present
747 (featurep 'number-types) <=> if one of the above features is
750 For complete details see: (Info-goto-node "(lispref)Enhanced Number Types")
752 ** Raw strings -- Kuehl.
754 SXEmacs tries to relieve backslashitis by implementing raw strings.
755 You'll imediately notice the benefit of raw strings when use them for
756 those hairy regexps. Consider the regular expression (from
759 "\\(?:^\\|[^\\]\\)\\(?:\\\\\\\\\\)*\\(\\\\[@A-Za-z]+\\)"
761 As a raw string it could be written as...
763 #r"\(?:^\|[^\]\)\(?:\)*\(\\[@A-Za-z]+\)"
765 Most of the SXEmacs core lisp code has been converted over to using
766 raw strings whereever appropriate.
768 ** Improved font-locking in a TTY -- Ferreira.
770 To illustrate this...
772 $ sxemacs -nw -vanilla
774 ...and look at the modeline. Now open a .c file and turn on
777 C-x C-f /path/to/file.c RET
778 M-x font-lock-mode RET
780 ** Compiler fixes -- Zajcev.
782 ** SXEmacs can no longer be built with a C++ compiler -- Youngs.
784 To build SXEmacs you will need a C compiler at least the equivalent of
785 GCC 2.95.3. Building with a C++ compiler is no longer supported.
787 ** Autoconf fixes, updates -- Freundt, Kuehl, Youngs.
789 All autoconf options now have a help string (for ./configure --help)
790 and the default setting for each option is noted.
792 ** PostgreSQL auto-detection improved -- Youngs.
794 If pg_config is in your $PATH, SXEmacs will add PostgreSQL support at
795 configure/build time.
797 ** Documentation (Texinfo) updates -- Freundt, Youngs.
799 The SXEmacs manual is now called "sxemacs" instead of "xemacs". C-h
800 C-i sxemacs RET to read it.
802 Most of the Texinfo docs now have been updated to say "SXEmacs"
803 whereever appropriate instead of "XEmacs".
805 ** GTK (version 1.2) build fixes -- Youngs.
808 * Changes in SXEmacs 22.1.2 (Audi)
809 ==================================
811 ** autoconf 2.59 compatible configure scripts -- Youngs, Purvis.
813 Many configure options have changed. Please run `./configure --help'
814 to see what the new options are.
816 ** Most win32 code is now gone -- Youngs, Freundt.
818 ** `describe-installation' report libc version on Slackware -- Youngs.
820 ** etags.c updated to Francesco's version 17.11 -- Youngs.
822 ** Support `ls --dired' properly -- Sperber.
824 ** FFI (Foreign Function Interface) updates -- Zajcev.
826 One of the most exciting things is that this version of SXEmacs can
827 download files from the internet _without_ the need of any XEmacs
828 packages being installed. If you have libcurl and enable FFI in
829 SXEmacs at build time, you can:
832 (curl:download "http://www.somedomain.com/path/file"
835 To put your mind at ease, libcurl is _NOT_ needed to build SXEmacs.
836 The above will work even if you install libcurl after
837 building/installing SXEmacs.
839 ** Don't echo GC messages for non-string GC'ing -- Zajcev.
841 This drastically reduces the number of "Garbage Collecting" messages
842 that you see in the echo area. Garbage collection is still happening,
843 it is just not in your face as much.
845 ** movemail.c security fixes -- Oskarsson.
847 ** PUI's *packages* buffer enhancements -- Koch.
849 ** Saner fallbacks for `backup-buffer' -- Youngs.
851 Based on an idea from JWZ, if the backup can't be written, try in
852 `auto-save-directory', and if that fails, fall back to $HOME.
854 ** OpenSSL support -- Freundt.
856 Of course. The OpenSSL library itself is actually separated into two
857 libraries: libcrypto and libssl. libcrypto is the part which comes to
858 elisp with the current API. libssl is planned for the near future.
860 With this interface/gateway we now have access to the wonderful world
861 of static cryptography (static here means no handshake/protocols/etc.).
865 - the OpenSSL PRNG = (pseudo) random number generator to provide
866 generating cryptographically secure randomness
868 - the OpenSSL MDs (message digests) to provide all sorts of hashing
869 (we had an md5 implementation already)
871 - the HMAC aka keyed hashing aka message authentication code to provide
872 hashes secured by a password
874 - the CIPHER engine (i.e. symmetric crypto systems) to provide
875 encryption/decryption routines secured by a password
877 - the PKEY engine (i.e. asymmetric crypto systems) to provide generation
878 and distribution of private/public key pairs (as probably known by
881 - the HYBRIDe engine aka PKCS aka public key crypto systems to provide
882 encryption based on (foreign) public keys and decryption with own
883 private keys to provide also digital signatures and verification (as
884 probably known by gpg)
886 ** Remove most of the generated files from the repo -- Youngs, Freundt.
888 ** Allow suppression of WM decorations -- Turnbull.
890 This makes balloon-help windows infinitely better behaved. Thank you
893 ** Fontify *scratch* buffer according to user's settings -- Kehoe.
895 ** Fix bug hanging SXEmacs when yanking > 260kb -- Kehoe.
897 ** lispref manual updated for SXEmacs -- Freundt.
899 ** PostgreSQL updates (mainly doc updates) -- Frenudt.
902 * Changes in SXEmacs 22.1.1 (Aston Martin)
903 ==========================================
905 ** user-init-directory set to ~/.sxemacs -- Youngs.
907 Symlinking this to your old ~/.xemacs directory is enough to get up
908 and running with SXEmacs.
910 ** Packages hierarchy default set to $prefix/lib/sxemacs -- Youngs.
912 Symlinking this to your old $prefix/lib/xemacs directory is enough to
913 get up and running with SXEmacs. SXEmacs will do this for you when
914 you do `make install'.
916 ** Rename items in the menubar -- Slusar, Youngs.
918 ** Beginnings of FFI -- Zajcev.
920 FFI is "Foreign Function Interface" and will allow access to functions
921 and libraries outside of SXEmacs from within lisp. Not completed yet,
922 but the basic infrastructure is in place.
924 ** FreeBSD build fixes -- Slusar.
926 ** M-x report-sxemacs-bug -- Youngs.
928 For now, this is just a wrapper around report-xemacs-bug with the
929 appropriate variables set to SXEmacs values.
931 ** Fix etags.c -- Slusar.
935 ** M-x build-report -- Youngs.
937 Make it work for SXEmacs.
939 ** Fix major bug in regex.c
941 This fixed a whole swag of crashes involving regexps and
944 ** Sync up with XEmacs 21.4 -- Various Developers.
947 * Changes in SXEmacs 22.1.0 (Alfa Romeo)
948 ========================================
950 This is the first release of SXEmacs. It is a fork of XEmacs
951 21.4.16. The vast majority of the changes between SXEmacs 22.1.0 and
952 the code it descended from, XEmacs 21.4.16, are purely renaming
953 "XEmacs" to "SXEmacs".
