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.

38 ** Bugs closed in this release:
40 76, 78, 88, 106, 108, 112, 121, 122, 125, 126, 127, 128, 131, 134,
41 135, 136, 137, 138, 139, 140
43 ** Coverity integrity scan fixes -- Ferreira.
45 Coverity (http://www.coverity.com/) offers source code integrity
46 analysis scans. These scans often uncover bugs and security issues
47 that would otherwise go unnoticed. When we first scanned the SXEmacs
48 code base with the Coverity scanner we had ourselves roughly 500
49 "defects". Nelson Ferreira has pretty much single-handedly fixed them
50 ALL!! Well done, Nelson and thanks a million!!!
52 ** Build related fixes/updates -- Ferreira, Freundt, Horelick, Meier,
55 Amongst the many, many, build chain updates I can also report that
56 SXEmacs will now build and run on OpenIndiana. Go us!
58 There were also fixes for: SuSe, PowerPC, MacOS, FreeBSD, NetBSD.
60 There were also many compiler warning fixes from Nelson and
63 ** FFI tweaks/fixes -- Keheo, Youngs, Zajcev.
65 ** Bitrot removal -- Burkhardt, Youngs.
67 Over the years things get old, obsolete, and forgotten. We've gone
68 through and cleaned house. Say goodbye to aRts, GTK1, tooltalk, and a
69 heap of rubbish in lib-src.
71 *** aRts -- Burkhardt.
73 *** tooltalk / CDE -- Youngs.
74 *** lib-src -- Youngs.
76 ** Whitespace cleanup -- Youngs.
78 Every file in the repository has had all trailing and otherwise
79 spurious whitespace removed/fixed. Obviously not an entirely critical
80 thing, but tidy is tidy. :-)
83 ** Support libpng 1.5.x -- Youngs.
86 * Changes in SXEmacs 22.1.14 (Geo)
87 ==================================
89 We switched to git! And this release cycle was all about updating the
90 build chain, version strings, and docs and whatnot from tla-isms to
93 You can now grab the SXEmacs sources via git with...
95 git clone http://git.sxemacs.org/sxemacs
98 * Changes in SXEmacs 22.1.12 (Fiat)
99 ===================================
101 ** Bugs closed in this release:
103 69, 86, 107, 109, 110, 111, 113, 114, 115, 117, 118, 120
105 ** Build chain fixes and updates -- Ferreira, Freundt, Youngs.
107 *** Fix building without eye-candy (*bars, widgets, etc)
108 *** Begin work on getting SXEmacs built on Arm Linux
109 *** Fix NetBSD 5 build
110 *** Mac OS build fixes
112 ** Source tree reorganisation -- Ferreira.
114 Nelson put a lot of working into reorganising the SXEmacs source tree
115 hierarchy. There are now several subdirectories under `src'...
117 src/database -- has the database code
118 src/ent -- has the "Enhance Number Types" code
119 src/events -- has the "events" code
120 src/media -- has all the multimedia code
121 src/mem -- has memory related code
122 src/mule -- has the MULE stuff
123 src/ui -- has the UI code common to all toolkits
124 src/ui/Gtk -- has the old (non-working) GTK 1 code
125 src/ui/TTY -- has the TTY UI code
126 src/ui/X11 -- has the X11 UI code
127 src/ui/lwlib -- has the Lucid stuff
129 This was done with the view to making maintenance and debugging
130 easier, and also to simplify adding new features.
132 ** FFI improvements, updates, and enhancements -- Zajcev
135 * SXEmacs 22.1.11 was never released.
137 See ChangeLog.d/ChangeLog-22.1.11 for all the changes in the
138 22.1.11 dev cycle, and for why it was not released.
140 * Changes in SXEmacs 22.1.10 (Excalibur)
141 ========================================
143 ** Bugs closed in this release:
145 41, 65, 74, 75, 79, 80, 81, 82, 83, 84, 85, 87, 89, 90, 91, 92, 93,
146 94, 95, 96, 97, 99, 100, 101, 102, 104
148 ** Cool New Sexy Stuff -- Zajcev, Ferreira, Freundt, Youngs.
150 Of course every release must have some cool new stuff. Here's what's
151 new in this release...
153 *** User defined readers
154 *** It's possible to display video in a glyph object in a buffer.
155 *** SXEmacs is now a fairly decent image viewing/manipulation app.
157 There's an undo/redo stack, zoom in/out, rotate, chop/crop, red-eye
158 reduction. There is a whole swag of transformations supported:
159 charcoal, contrast, despeckle, edge, enhance, equalise, gausian blur,
160 negate, normalise, oil painting, radial blur, 3D button effect,
161 sharpen, solarise, and swirl.
163 Who needs The Gimp when you have SXEmacs!
165 *** Added some MacOS icons.
166 *** Support for sqlite3 via FFI
167 *** New way for SXEmacs to handle different file types.
169 It allows you to have #'find-file take different actions based on a
170 predicate. See the new variable `find-file-magic-files-alist'.
172 *** Enable PNG transparent backgrounds
174 Unfortunately this doesn't work if you use a background pixmap.
176 *** FFI callbacks implemented.
177 *** Dbus support via FFI (not completed)
179 This should be considered very much incomplete and experimental. Only
180 rudimentary support is there so far.
182 ** Build chain fixes/improvements -- Burkhardt, Ferreira, Freundt, Youngs.
184 Quite a few build chain related changes were made in this release,
187 *** Work around a bug in GCC 4.5.0
188 *** Powerpc/BSD cpu detection
189 *** A Freedesktop.org compliant sxemacs.desktop file is now installed.
190 *** Updated FFmpeg detection.
191 *** OpenSSL 1.0.0 detection. OpenSSL is no on by default.
192 *** Fix a link error when building with no MPQ
193 *** Fix a minor bison related issue (YYSTYPE)
194 *** Fix building with latest SoX
195 *** Fix --without-x builds
196 *** Fix many C compiler warnings and elisp byte-compiler warnings.
197 *** Fix install for non-FFI and non-Mule builds
198 *** Fix etags build for systems without getopt_long
199 *** Fix (hopefully) parallel builds
200 *** Fix BDWGC-enabled builds
202 ** Minor updates to BDWGC code -- Freundt.
204 ** Catch up with latest ffmpeg API changes -- Freundt.
206 ** Fix for latest ediff -- Ferreira.
208 Changes emacs-internal to escape-quoted.
210 ** Fix for subwindow resizing -- Zajcev.
212 ** Various additions/updates to the contrib directory -- Ferreira
214 ** FFI improvements -- Zajcev
216 ** ENT fixes -- Freundt.
218 ** TTY fixes -- Ferreira.
220 ** Cleaner dump file (less pollution from the build/src dir) -- Freundt, Youngs.
222 ** Improve #'file-basename -- Ferreira
224 It can now take a 2nd arg for extension stripping.
226 ** Misc doc fixes/updates -- Burkhardt, Ferreira, Freundt, Zajcev, Youngs.
228 * Changes in SXEmacs 22.1.9 (Edsel)
229 ===================================
231 ** Bugs closed in this release:
233 32, 33, 34, 35, 36, 37, 38, 39, 40, 42, 45, 46, 47, 48, 49, 50, 51,
234 53, 54, 55, 56, 57, 58, 59, 60, 61, 62
236 See http://issues.sxemacs.org/ for the details.
238 ** Build chain fixes and improvements -- Freundt, Ferreira.
240 Better detection of ALSA, ffmpeg, libffi, libbind, and many other
241 various bits and pieces.
243 General build related fixes were made for MacOS, Solaris, HPUX, and of
246 ** New function, #'mapfam -- Freundt.
248 This new function is an extrememly powerful replacement for _all_ of
249 the current map functions. It not only can do the job of the
250 existing map functions, but can also convert any sequence to any
251 other sequence. Lots of other cool features as well, see its doc
252 string for full details.
254 ** Init file migration code removed -- Youngs.
256 We feel that it is better to NOT mess with other emacsen's set ups.
258 ** Compiler warning fixes -- Freundt.
260 ** PNG images optimised for size -- Burkhardt.
262 All of the PNG images that we ship have been optimised for size.
264 ** Re-work auto-autoloads loading a little -- Ferreira.
266 Priority is given to packages installed under ~/.sxemacs/ and care is
267 taken to eliminate those "foo-autoloads already loaded" warnings.
269 ** Support 256 colour terminals -- Ferreira.
271 Support for 256 colour terminals and colour resolution through
272 approximation for tty devices.
274 ** New FFI util, ffi-magic.el -- Youngs.
276 Uses libmagic to guess file type.
278 ** Cool new stuff in the contrib directory -- Youngs, Ferreira.
280 There are tla hook scripts, build scripts, and build-report scripts.
282 ** New garbage collector BDWGC -- Freundt.
284 SXEmacs can now use the Boehm-Demers-Weiser garbage collector. It is
285 still experimental at this stage and there are known bugs (memory
286 leak). If you have plenty of RAM it is quite usable, and noticably
287 faster than non-BDWGC SXEmacsen. This new feature is not on by
288 default. To get it, configure with --with-experimental-features=all.
290 ** Support for BSD's MP removed -- Freundt.
292 ** Emodule search path/loading fixes -- Youngs.
294 Emodule load path has been made sane. #'load-module and
295 #'locate-module have both been vastly improved and both have
298 ** FFI improvements -- Youngs.
300 The FFI code has been improved so that it can be compatible with
301 XEmacs 21.5 for when they merge our FFI into their code base. Also
302 #'ffi-load and #'ffi-load-library no longer need to be given a file
303 extension as part of the arg to allow for different platforms having
304 different shlib extensions.
306 Also, some UI enhancements were added to ffi-curl.el and
309 ** Etags improvements -- Youngs.
311 A bit of "UI" has been added to etags.el, as well as some code
314 ** Various minor tweaks, fixes, and documentation -- Burkhardt, Ferreira,
315 Freundt, Wallington, Youngs.
318 * Changes in SXEmacs 22.1.8 (Daimler)
319 =====================================
321 ** Bugs closed in this release: 22, 24, 26, 27, 29, 31
323 You might notice a double up of bug numbers here from the previous
324 release. The index got reset and so some bug ID numbers were
327 ** Build chain fixes, improvements -- Freundt, Ferreira, Youngs.
329 We now have a libtool-based build chain.
331 ** Minor improvements to packages bootstrapping -- Youngs.
333 ** User's custom file renamed to custom-${USER}.el -- Youngs.
335 The old variant, custom.el is still used if that file exists.
337 ** Sync XEmacs 21.5's cus-*.el, autoload.el, subr.el -- Youngs.
339 Amongst other things, this sync brings custom-defines, many new custom
340 widgets, and an implementation of the `:inherit' face keyword.
342 ** Skiplist fixes -- Freundt.
344 ** Introduce custom printers -- Zajcev.
346 ** Update GPL licenced stuff to GPL version 3 -- Youngs.
348 ** Add a rc.d inspired init mechanism -- Ferreira.
350 ** Font lock improvements -- Ferreira.
352 ** Byte compile defcustom init values, saving lisp values for correct editing -- Kehoe.
354 Sync from XEmacs 21.5.
356 ** Improve interactivity of custom prompting -- Verna.
358 Sync from XEmacs 21.5.
360 ** Resize echo area when needed -- Aichner, Turnbull, Youngs.
362 Sync from XEmacs 21.5. Don't confuse this with rsz-minibuffer.el in
363 the packages, This is different, the minibuffer and echo area are 2
366 ** #'describe-function (C-h f) prints global keybindings for commands -- Kehoe, Youngs.
368 Sync from XEmacs 21.5.
370 ** New `%b' spec for #'format -- Freundt, Kehoe.
372 This is for converting between ints and bit vectors.
374 ** Sample init file updated -- Youngs.
376 ** Fix the bug exposed by our weak-tests.el -- Youngs.
378 ** Update the man page -- Youngs.
380 ** Support character classes in regexps -- Freundt.
382 ** Misc trivial changes such as doc fixes, typos, etc -- Burkhardt,
383 Freundt, Ferreira, Youngs.
386 * Changes in SXEmacs 22.1.7 (De Lorean)
387 =======================================
389 ** Bugs closed in this release: 13, 20, 21, 24, 25, 27, 28, 31
391 ** Much reworking of the build chain -- Freundt, Ferreira, Youngs.
393 Quite a bit has changed here, a few options have been changed, added,
394 or removed. So if you haven't been following the development it might
395 pay you to have a look at our configure's --help output.
397 ** Fix emodule loading on 64bit machines -- Freundt.
399 ** Security fix in movemail.c (mktemp()->mkstemp()) -- Youngs.
401 ** Etags synched up to upstream 17.32 -- Burkhardt, Youngs.
403 ** Updates/fixes to dllists/skiplists -- Freundt, Ferreira.
405 ** Lots of updates in the ENT area (Enhanced Number Types) -- Freundt.
407 Some stuff has been moved to an external emodule, "ASE" (Algebraic
408 Structures for ENT or "ASE Supersedes ENT"). Also directed graphs
409 have been introduced (sparse representation only so far). And
410 introduce heaps (dense, dynamic, and week).
412 ** cl.el meets C -- Freundt.
414 We've begun work on implementing the common lisp macros as an external
415 emodule. The main focus here is speed, and initial benchmarks are
416 _very_ exciting... The emod version of #'dotimes (#'cl:dotimes) can be
417 nearly 200 times faster than its elisp counterpart!
419 This isn't finished yet, but watch future releases.
421 ** package-suppress mechanism ported from XEmacs 21.5 -- Freundt, Youngs.
423 ** Asynchronous version of #'curl:download added called #'curl:download& -- Freundt.
425 ** Font-lock improvements, especially on TTYs -- Ferreira.
427 ** Fix info search path -- Ferreira.
429 ** Change default setting for progress guages to be off -- Youngs.
431 ** Multimedia updates/fixes -- Freundt, Youngs.
433 Lots of reworking has been done here, especially with PulseAudio,
434 ffmpeg, and threading of the audio jobs etc. Support for gstreamer
435 and xine has been dropped, and libmagic added.
437 ** New macro to define "toggle" variables #'define-toggle-variable -- Zajcev
439 I wouldn't normally list a single new macro in this file, but this one
440 deserves a mention. It sets up toggle variables, including
441 #'turn-on-VAR, #'turn-off-VAR, and #'toggle-VAR. Very nifty.
443 ** Many many compiler warnings have been fixed -- Freundt, Youngs.
445 Almost all byte-compiler warnings have been fixed in our build. And a
446 good deal of the warnings in the C code of a standard build has been
449 ** GC fixes/updates -- Freundt.
451 ** A contrib directory has been added to the tree -- Freundt.
453 So far there are patches in there to pop3.el, smtpmail.el, and
454 starttls.el which takes advantage of some of SXEmacs' cool native
455 features like OpenSSL.
457 Watch this space for more nifty things.
459 ** Minor misc fixes (typos etc) -- Zajcev, Burkhardt, Freundt, Ferreira, Youngs.
461 ** Documentation updates:
462 o sppm.texi -- Burkhardt, Youngs.
463 o lispref.texi -- Freundt, Youngs.
464 o tips.texi -- Freundt.
465 o building.texi -- Youngs.
466 o processes.texi -- Ferreira.
467 o internals.texi -- Freundt.
469 * Changes in SXEmacs 22.1.6 (Cadillac)
470 ======================================
472 ** ENT (Enhanced Number Types) updates and fixes -- Freundt, Ferreira.
474 ** MM (MultiMedia) updates and fixes -- Freundt, Ferreira, Youngs.
476 ** FFi (Foreign Function Interface) updates -- Freundt, Zajcev.
478 ** New ffi-gcrypt.el -- Freundt.
480 ffi-gcrypt.el brings GnuPG's libgcrypt bindings to SXEmacs.
482 ** Line/column numbers in modeline are now padded -- Ferreira.
484 ** New skiplists -- Freundt.
486 This is a basic implementation of Pugh's skip lists. Their efficiency
487 is overwhelming when compared to alists or plists. They also perform
488 better on insertion and removal than large hash-tables (due to the
489 resizing/rehashing which takes place). They can be created almost as
490 fast as lisp lists and thus beat hash-tables there, too.
492 ** Fix module (DSO) load paths -- Youngs.
494 ** SXEmacs maintainer turned 40 -- Mr and Mrs Youngs.
496 This is a recurring bug that was first discovered on June 19th, 1966.
498 ** Test suite updates/improvements -- Turnbull, Youngs.
500 ** Etags updates/fixes -- Ferreira, Youngs.
502 Sync to Francesco's version 17.20 etags. And major surgery on
503 etags.el to make it usable, fixing completion and support for the
506 ** Fix raw string parsing -- Kehoe.
508 A problem that arose in lisp-interaction-mode, where raw strings
509 were parsed as normal strings if you did a C-j after them, becase
510 forward-sexp couldn~t handle them.
512 ** Sync bytecomp-runtime.el with XEmacs 21.5 -- Youngs.
514 The significance of this is that SXEmacs now has all those cool
515 with,if,when,and-boundp macros for clean byte-compiler warning
518 ** OpenSSL updates/fixes/improvements -- Freundt.
520 A rewrite of the old handshake functions. SSL connections can be
521 established as before: open a network-stream, call ossl-ssl-handshake
522 on it and store the result. The new implementation provides also
523 support for certificate authorities (CA), for peer certificates and,
524 using the network-server-streams, secure listening sockets. This will
525 allow to connect/accept to/from servers/clients which require valid
528 ** New PulseAudio support -- Freundt.
530 PulseAudio is the successor to PolypAudio. Because there were so few
531 users using Polyp (think we counted 2 and they're both SXEmacs
532 developers) SXEmacs support for PolypAudio was replaced by PulseAudio
535 ** New Caching compiled regular expressions -- Freundt.
537 All you really need to do to use them is assign them (the regexp) to a
538 variable. Here's an example...
540 (let ((reg1 "^;+\\s-")
542 (while (and (re-search-forward reg1 nil t)
543 (re-search-forward reg2 nil t))
548 (while (and (re-search-forward "^;+\\s-" nil t)
549 (re-search-forward "\\s-+;+" nil t))
552 The former construct will store the compiled regular expressions in the
553 object property list of `reg1' and `reg2' on the first iteration of
554 `while', all following iterations will then use the already compiled
555 regexps. The latter construct will behave as before, the regular
556 expression is compiled and stored, but since the string is hard-coded in
557 the buffer, it will be newly generated (with empty object-plist of
558 course) during every cycle of the while loop.
560 ** Cleaner dump file -- Freundt, Youngs.
562 The portable dump file was getting polluted with things in the
563 packages load-path causing all sorts of undefined and unexpected
564 impossible to track down bugs. No longer!
566 ** Fix many many byte-compiler warnings in building core lisp -- Youngs.
568 ** Fix building without emodules -- Ferreira.
570 ** New Support emodules on MacOS -- Ferreira.
572 ** Fix BerkeleyDB detection on NetBSD -- Ferreira.
574 ** New SXEmacs icons added to dist -- Ferreira.
576 ** Major restructuring of the build chain and install layout -- Freundt.
578 SXEmacs is now pretty much a completely autotool'd project... automake,
579 autoheader, the whole 9 yards. And if that wasn't enough, we are now
580 also, to the best of our knowledge, reasonably FHS-compliant with our
583 The changes to the install directory hierarchies are:
585 now go to... before went to...
586 lisp share/sxemacs-22.1.6/lisp/ lib/sxemacs-22.1.6/lisp/
587 etc share/sxemacs-22.1.6/etc/ lib/sxemacs-22.1.6/etc/
588 info share/info/ lib/sxemacs-22.1.6/info/
589 headers include/sxemacs/22.1.6/ lib/sxemacs-22.1.6/<arch>/include/
591 Packages are now searched for in
593 $prefix/share/sxemacs/{{s,}xemacs,mule,site}-packages/
595 instead of $prefix/lib/sxemacs/.../
597 ** DnD dragged out and dropped on /dev/null -- Freundt.
599 ** Misc build fixes -- Freundt, Ferreira, Youngs.
601 ** Fix `tags' Makefile target -- Youngs.
603 ** Fix bug in `lib-complete' -- Freundt.
605 The bug was causing `find-library' to visit the .elc instead of the
606 .el if you were running SXEmacs in-place from the build tree.
608 ** Fix stack overflow crash in mapconcat -- Ferreira.
610 ** Large update of about.el -- Freundt, Ferreira, Youngs.
612 See: M-x about-sxemacs
614 ** Various documentation updates/fixes/improvements -- Freundt, Ferreira, Youngs.
617 * Changes in SXEmacs 22.1.5 (Bugatti)
618 =====================================
619 First up, this release has turned into a purely maintenance/bugfix
620 release. SXEmacs 22.1.4 had several build-related issues that this
623 ** version.sh fix -- Youngs.
625 Fix a problem with the wrong version being generated.
627 ** Autoconf fixes -- Youngs, Ferreira, Freundt.
629 Lots of changes to the autoconf configure script
631 - Recognise $CFLAGS environment variables
632 - X toolkit autodetection redone
633 - TTY autodetection fixed
634 - PostgreSQL detection properly reported
635 - Change allowed values for menubars, dialogs, widgets
636 menubars -- no athena or motif
639 - Set configure's "bugreport address" to
640 http://issues.sxemacs.org.
641 - Fix gdbm/berkdb detection
642 - Improve libc version detection
644 ** New Makefile target (build-report) -- Kuehl.
646 `make build-report' is a convenience target. It automatically
647 captures make output to files that `M-x build-rpt' knows about. It
648 also runs `make check'. The SXEmacs developers recommend that you use
649 this target to build SXEmacs.
651 ** PROBLEMS updated -- Kuehl, Freundt.
653 Document SELinux/libffi issues and GMP/mpfr Fedora issues.
655 ** pdump/ENT fix for *BSD -- Freundt.
657 ** Documentation updates/fixes -- Youngs, Ferreira, Freundt.
660 * Changes in SXEmacs 22.1.4 (Bentley Turbo)
661 ===========================================
663 ** Many more image formats via FFI/libWand -- Freundt.
665 FFI-enabled SXEmacs can load up libWand and thus display any image
666 format that libWand (ImageMagick) supports.
668 ** Lots of updates to the ENT (Enhanced Number Types) code -- Freundt.
670 ** Mule is on by default -- Youngs.
672 ** Embeddable keyboard macros -- Kuehl.
674 This means that the following sort of thing is possible:
677 C-x ( foo C-x e C-x )
682 ** Default widgets/dialogs to Athena instead of Motif -- Youngs.
684 ** OpenSSL updates -- Freundt.
686 Digest, encryption, and decryption routines that operate on files has
687 been added. Previously this was only available for buffers.
689 ** Build reports have been revamped -- Youngs, Freundt.
691 The SXEmacs build report no longer conflicts with the XEmacs
692 build-report.el. Plus ours also reports on shared lib dependencies
693 and config.h stuff. Sending from Gnus is also supported.
695 ** FFI updates/fixes -- Youngs, Zajcev, Freundt.
697 ** Ability to build postscript, pdf, and html docs -- Ferreira.
699 ** Double linked lists and bloom filters implemented -- Freundt.
701 Bloom filters are a space and time-efficient way to decide about the
702 membership of an element to a given set. Using lisp-lists or vectors,
703 one usually has to traverse the entire list or vector, before
704 membership can be decided. Using hash tables, membership decision is
705 in O(1) (bloom filters also decide in O(1)), but the hash-table's size
706 grows proportionally with the number n of elements, thus its space
707 complexity is O(n), whereas Bloom filters take a constant amount of
708 space regardless how many elements are in it.
710 ** Lightning fast recursive version of directory-files -- Freundt.
712 It's called `directory-files-recur' and in some situations it is even
713 faster than GNU's find(1).
715 ** Portuguese added to etc/HELLO -- Ferreira.
717 ** Massive improvements, enhancements for multimedia (audio) -- Freundt.
719 SXEmacs supports several "sound servers" like: OSS, NAS, ESD, Polypaudio,
720 ALSA, aRts, and Jack. And media streams can be handled by sndfile, ffmpeg,
721 sox, mad, xine, gstreamer. The SXEmacs developers recommend Polyp/ffmpeg
724 And yes, SXEmacs _can_ play mp3 files. :-)
726 ** Autoconf fixes/updates -- Youngs, Freundt.
728 All of the enable/disable options have been converted to with/without
729 options. This allows us to sort them into groups.
731 Also fixes were made to allow building on FreeBSD and NetBSD.
733 ** Big update for the FAQ -- Youngs, Freundt.
735 ** Server Sockets! -- Ferreira.
737 SXEmacs now has server sockets (Yay!). See
738 `open-network-server-stream'.
740 ** Compiler fixes (gcc 2.95) -- Freundt.
742 ** bug-reporter update -- Youngs.
744 `report-sxemacs-bug' now directs people to our BugZilla installation
745 at http://issues.sxemacs.org/
747 ** Documentation updates/fixes/improvements -- Youngs, Ferreira, Freundt.
750 * Changes in SXEmacs 22.1.3 (BMW)
751 =================================
753 ** OpenSSL updates, improvements, and fixes -- Freundt.
755 ** FFI updates, and fixes -- Zajcev.
757 FFI now defaults to "on" if libffi can be found at configure time. It
758 you don't want this, use: `--disable-ffi'.
760 FTP downloads with `curl:download' is working properly now. And with
761 HTTP transfers you can transfer just the HTTP header for a file if you
764 ** Extent/glyph fixes -- Sidwell, Kuehl.
766 ** 32 mouse buttons supported -- Youngs.
768 (global-set-key [(button32)] 'some-function) is valid in SXEmacs.
770 ** Modeline tweaks -- Ferreira.
772 Move line/column number indicators to left side (aka XE 21.5)
774 ** M-x uptime -- Youngs.
776 Every good OS has an uptime util, SXEmacs is no exception. Reports
777 uptime in various formats.
779 ** ia64 build fixes -- Lesjak.
781 ** `C-h n' will no longer find NEWS files from packages -- Youngs.
783 ** List of package mirrors updated -- Aichner, Skyttä.
785 ** Bootstrappable PUI -- Youngs.
787 SXEmacs no longer needs to have _any_ packages pre-installed before
788 PUI can be used. See (Info-goto-node "(sxemacs)Bootstrapping PUI").
790 ** Bignums, and a whole swag of sexy new number goodness -- Freundt.
792 Bignums, bigfloats, and ratios that you may know from XEmacs 21.5 are
793 now in SXEmacs. That and a whole lot more...
795 Features provided when all of the library demands are met:
798 (featurep 'bignum) <=> if MPZ from GMP or BSD MP is present
801 (featurep 'ratio) <=> if MPQ from GMP is present
804 (featurep 'bigfloat) <=> if MPF from GMP is present
806 (featurep 'bigfr) <=> if MPFR is present
808 (featurep 'bigc) <=> if MPC is present
810 (featurep 'number-types) <=> if one of the above features is
813 For complete details see: (Info-goto-node "(lispref)Enhanced Number Types")
815 ** Raw strings -- Kuehl.
817 SXEmacs tries to relieve backslashitis by implementing raw strings.
818 You'll imediately notice the benefit of raw strings when use them for
819 those hairy regexps. Consider the regular expression (from
822 "\\(?:^\\|[^\\]\\)\\(?:\\\\\\\\\\)*\\(\\\\[@A-Za-z]+\\)"
824 As a raw string it could be written as...
826 #r"\(?:^\|[^\]\)\(?:\)*\(\\[@A-Za-z]+\)"
828 Most of the SXEmacs core lisp code has been converted over to using
829 raw strings whereever appropriate.
831 ** Improved font-locking in a TTY -- Ferreira.
833 To illustrate this...
835 $ sxemacs -nw -vanilla
837 ...and look at the modeline. Now open a .c file and turn on
840 C-x C-f /path/to/file.c RET
841 M-x font-lock-mode RET
843 ** Compiler fixes -- Zajcev.
845 ** SXEmacs can no longer be built with a C++ compiler -- Youngs.
847 To build SXEmacs you will need a C compiler at least the equivalent of
848 GCC 2.95.3. Building with a C++ compiler is no longer supported.
850 ** Autoconf fixes, updates -- Freundt, Kuehl, Youngs.
852 All autoconf options now have a help string (for ./configure --help)
853 and the default setting for each option is noted.
855 ** PostgreSQL auto-detection improved -- Youngs.
857 If pg_config is in your $PATH, SXEmacs will add PostgreSQL support at
858 configure/build time.
860 ** Documentation (Texinfo) updates -- Freundt, Youngs.
862 The SXEmacs manual is now called "sxemacs" instead of "xemacs". C-h
863 C-i sxemacs RET to read it.
865 Most of the Texinfo docs now have been updated to say "SXEmacs"
866 whereever appropriate instead of "XEmacs".
868 ** GTK (version 1.2) build fixes -- Youngs.
871 * Changes in SXEmacs 22.1.2 (Audi)
872 ==================================
874 ** autoconf 2.59 compatible configure scripts -- Youngs, Purvis.
876 Many configure options have changed. Please run `./configure --help'
877 to see what the new options are.
879 ** Most win32 code is now gone -- Youngs, Freundt.
881 ** `describe-installation' report libc version on Slackware -- Youngs.
883 ** etags.c updated to Francesco's version 17.11 -- Youngs.
885 ** Support `ls --dired' properly -- Sperber.
887 ** FFI (Foreign Function Interface) updates -- Zajcev.
889 One of the most exciting things is that this version of SXEmacs can
890 download files from the internet _without_ the need of any XEmacs
891 packages being installed. If you have libcurl and enable FFI in
892 SXEmacs at build time, you can:
895 (curl:download "http://www.somedomain.com/path/file"
898 To put your mind at ease, libcurl is _NOT_ needed to build SXEmacs.
899 The above will work even if you install libcurl after
900 building/installing SXEmacs.
902 ** Don't echo GC messages for non-string GC'ing -- Zajcev.
904 This drastically reduces the number of "Garbage Collecting" messages
905 that you see in the echo area. Garbage collection is still happening,
906 it is just not in your face as much.
908 ** movemail.c security fixes -- Oskarsson.
910 ** PUI's *packages* buffer enhancements -- Koch.
912 ** Saner fallbacks for `backup-buffer' -- Youngs.
914 Based on an idea from JWZ, if the backup can't be written, try in
915 `auto-save-directory', and if that fails, fall back to $HOME.
917 ** OpenSSL support -- Freundt.
919 Of course. The OpenSSL library itself is actually separated into two
920 libraries: libcrypto and libssl. libcrypto is the part which comes to
921 elisp with the current API. libssl is planned for the near future.
923 With this interface/gateway we now have access to the wonderful world
924 of static cryptography (static here means no handshake/protocols/etc.).
928 - the OpenSSL PRNG = (pseudo) random number generator to provide
929 generating cryptographically secure randomness
931 - the OpenSSL MDs (message digests) to provide all sorts of hashing
932 (we had an md5 implementation already)
934 - the HMAC aka keyed hashing aka message authentication code to provide
935 hashes secured by a password
937 - the CIPHER engine (i.e. symmetric crypto systems) to provide
938 encryption/decryption routines secured by a password
940 - the PKEY engine (i.e. asymmetric crypto systems) to provide generation
941 and distribution of private/public key pairs (as probably known by
944 - the HYBRIDe engine aka PKCS aka public key crypto systems to provide
945 encryption based on (foreign) public keys and decryption with own
946 private keys to provide also digital signatures and verification (as
947 probably known by gpg)
949 ** Remove most of the generated files from the repo -- Youngs, Freundt.
951 ** Allow suppression of WM decorations -- Turnbull.
953 This makes balloon-help windows infinitely better behaved. Thank you
956 ** Fontify *scratch* buffer according to user's settings -- Kehoe.
958 ** Fix bug hanging SXEmacs when yanking > 260kb -- Kehoe.
960 ** lispref manual updated for SXEmacs -- Freundt.
962 ** PostgreSQL updates (mainly doc updates) -- Frenudt.
965 * Changes in SXEmacs 22.1.1 (Aston Martin)
966 ==========================================
968 ** user-init-directory set to ~/.sxemacs -- Youngs.
970 Symlinking this to your old ~/.xemacs directory is enough to get up
971 and running with SXEmacs.
973 ** Packages hierarchy default set to $prefix/lib/sxemacs -- Youngs.
975 Symlinking this to your old $prefix/lib/xemacs directory is enough to
976 get up and running with SXEmacs. SXEmacs will do this for you when
977 you do `make install'.
979 ** Rename items in the menubar -- Slusar, Youngs.
981 ** Beginnings of FFI -- Zajcev.
983 FFI is "Foreign Function Interface" and will allow access to functions
984 and libraries outside of SXEmacs from within lisp. Not completed yet,
985 but the basic infrastructure is in place.
987 ** FreeBSD build fixes -- Slusar.
989 ** M-x report-sxemacs-bug -- Youngs.
991 For now, this is just a wrapper around report-xemacs-bug with the
992 appropriate variables set to SXEmacs values.
994 ** Fix etags.c -- Slusar.
998 ** M-x build-report -- Youngs.
1000 Make it work for SXEmacs.
1002 ** Fix major bug in regex.c
1004 This fixed a whole swag of crashes involving regexps and
1007 ** Sync up with XEmacs 21.4 -- Various Developers.
1010 * Changes in SXEmacs 22.1.0 (Alfa Romeo)
1011 ========================================
1013 This is the first release of SXEmacs. It is a fork of XEmacs
1014 21.4.16. The vast majority of the changes between SXEmacs 22.1.0 and
1015 the code it descended from, XEmacs 21.4.16, are purely renaming
1016 "XEmacs" to "SXEmacs".
