32.1.11-pre-1
4        Don't crash doing zlocate with bad tickets. [BZ 12]
5        Metion the path for the owlconf in intro.txt [BZ 54]
6        Print better error message if startup fails due to unreadable
7           .owlconf [BZ 57]
8        In load-subs: Print an error message if the file is unreadable or
9          doesn't exist, UNLESS load-subs is called with no arguments.  In
10          that case only print an error if the file exists but isn't
11          readable.  Still prints an error either way if zephyr reports a
12          failure. [BZ 19]
13        Fixed some small memory leaks in logging if files unwriteable
14        If the variable logfilter is set it names a filter.  Any messages
15          matching this filter are logged.  This is an independent
16          mechanism from the other logging variables.  If you want to
17          control all logging with logfilter the other variables must be
18          set to their default (off) settings. [BZ 37]
19        Relatively substantial changes made under the hood to support
20          filter logging.  Now have more consistent interfaces to
21          creating messages etc.  Still needs more work though.
22        Deal gracefully with being resized as small as 1x1 [BZ 3]
23
242.1.10
25        Fix a new problem finding libdes425
26        Don't crash on very long hostnames [BZ 52]
27        In 'sub' command, create .zephyr.subs if it doesn't exist [BZ 15]
28        A fix for certain resize crashes (partly from alexmv) [BZ 55]
29        Turn off ISTRIP (gildea)
30       
312.1.9
32        Include /usr/include/kerberosIV if it's found
33       
342.1.8
35        Do OLC formatting for anything coming from olc.matisse
36        Improvements to popup size algorithm (from gildea)
37        Improved 'show colors' with non-colored labels
38       
392.1.7
40        The colorclass command is added, to make colorization easy
41        Handle MIT Athena OLC zephyrs correctly
42        Updated ktools website / bug address
43        Do ntohs() when printing zephyr port in zephyr info
44        Updated man page
45       
462.1.6
47        Fixed three bugs found by Valgrind.
48        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
49          would cause a segfault.
50        pexec will now incrimentally display data as it is output
51          by the child process.  Additionally, commands running under
52          pexec may now be killed by quitting out of the popless window.
53        Added muxevents select loop dispatcher.  File descriptors may
54          be registered with muxevents and handlers will be dispatched
55          to when data is available for non-blocking read/write/except.
56        Switched the stderr_redir stuff to use muxevents.
57        Print C-\ correctly (from gildea)
58        Dropped first brace in muxevents functions for consistency
59        Catch SIGHUP and SIGTERM and do a proper logout
60       
612.1.5
62        Added a licence
63        The 'personalbell' variable can now be set to 'on' 'off' or
64          the name of a filter to match against
65        The 'loglogins' variable now controls whether login/logout
66          messages are logged.  It is off by default.  For now this
67          affects only AIM messages, later zephyr login/logout messages
68          will also be logged if this is set to 'on'
69        Added 'show license'
70       
712.1.4
72        Normalize and downcase AIM names for logging
73        Fixed a bug where sending a null zsig could cause a crash
74        Better 'away' toggling if only one protocol is away.
75
762.1.3
77        Added perl filter elements.  Similar to having "filter <subfilter>"
78          in a filter, you may also have "perl <functionname>"
79          where <functionname> is passed an owl::Message object and
80          returns 0 or 1 depending on whether the message matches
81          that element of the filter.
82        Don't print an error about loading subs if there is no
83          .zephyr.subs
84        Do the initial zephyr_buddy_check when pseduologin set to true.
85        Updated man page
86       
872.1.2
88        removed unused filter_depth variable
89        Fixed memory bug on receiving pings
90       
912.1.1
92        Filters of filters now work.
93        Removed the "possibly not readable" part of the config parsing
94          error
95        In the sepbar, reverse video the view name when it's not set to
96          view_home (as opposed to the static 'all').
97        The '!' key (bound to 'view -r') now creates a negative version of
98          the current view and switches to it.  i.e. "show me all the
99          messages that are not these"
100        Added the 'ignorelogins' variable
101        Log when outgoing personal message fails
102        Removed file descriptor from sigpipe catcher printer just for now,
103          since the field does not exist on OSX
104        Added an ifndef for socklen_t in libfaim/ft.c
105        Added the 'aim search' command.  The popup on callback may be
106          dangerous, should switch to an admin msg for results, or add a
107          new event queue
108        First pass at AIM away messages.  It is a little different from
109          what most clients seem to do, in that an away reply is sent for
110          each message received.  Most clients only reply to the first one
111          per away-session.
112        Now have a set of 'aaway' commands and variables just like the
113          'zaway' ones (except that changing the 'aaway' variable talks to
114          the server)
115        The new 'away' command does everything for both AIM *and* zephyr.
116          There is a known funkiness here, where if you turn one away on,
117          and then use 'away' (or 'A') to toggle, you will turn on off and
118          the other on.  Just leaving it for now.  Should do better in the
119          next patch.
120        The 'A' key is bound to 'away'
121        Status bar can now read AWAY, Z-AWAY or A-AWAY.
122        Changed C-n to scroll down just a line in popless
123        If the config exists but is not readable, print an error before
124          exiting
125        Only print forced AIM logout message once.
126        Don't bind F1 to help in edit context
127        Fix bug in 'getsubs' with no tickets
128        New code for getting users from .anyfile
129        Added the 'pseudologins' variable, and code to do it
130        new attributes 'pseudo' 'logintty' and 'loginhost'
131        Don't print extra new lines in popless_file
132        New zephyr_get_field function
133       
1342.0.14
135        Fixed missing word in startup message
136        Better 'status' command
137        Use '+' for popwin corners when 'fancylines' is off
138        Allow TERMINFO to be overridden in the envrionment
139        Command line arg -D turns on debugging and deletes previous
140          debugging file
141        Do ~ expansion in 'dump' command.
142        Current directory added to 'status' command
143        Massive changes to libfaim and aim
144       
1452.0.13
146        Changed startup message for new mailing list
147        blist now prints AIM info even if .anyone is unreadable
148        Catch SIGPIPE and print an error rather than crashing.
149                [It's possible that this may have some portability
150                issues under Solaris and we may need to add some
151                configure stuff around SA_SIGINFO...]
152        Handle the case in aim_bstream_send where aim_send returns -1,
153                although there is likely an underlying problem here
154                that would lead to this case.
155        Print the username on aim login failure, not something random like
156                the password.  ;)
157        Un-word-wrap text when sending AIM messages.
158        Replace the main loop continue in the keyboard handler with an else.
159       
1602.0.12
161        Command history now doesn't allow the last entry
162           to be repeated
163        If format_msg returns "" print "<unformatted message>"
164        Better align oneline admin and loopback messages
165        Print an admin message indicating when subscriptions can
166           not be loaded on startup
167        Set aim_ignorelogin_timer to 15 by default
168        Admin message on login/logout of AIM
169        Fixed double quoting in smartzpunt
170        Added timestamp to login/logout messages
171        Fixed replies to loopback messages
172        Fixed smartnarrow on classes/instances with spaces
173        Added the 'loggingdirection' variable
174        All loopback messages log to 'loopback' now
175        Print an error message if trying an invalid color for a filter
176        Fixed bug causing > not to go to end of editwin every time
177       
1782.0.11
179        Updated basic help
180        Display CC: in outgoing CC messages
181        More AIM logout detection
182        Don't proclaim "interfaces changed" on first build.
183        Added the 'loopback' message type
184        Added the 'loopwrite' command
185        Added a timestamp to the default style
186        Zpunt now works with weird regex characters

199        Added feature for capturing stderr messages
200           from commands and displaying them in the errors buffer.
201        Create an admin message explaning that a zephyr couldn't
202           be sent
203        Better reporting of perl errors (both into the errqueue
204                and also clearing the error after displaying it).
205        Allow default_style to be specified in config.
206        Added errqueue

213        New libfaim
214        Added the 'source' command.
215        Make sure that a newline is always at the end of messages
216                returned by perl style formatting functions.
217        Add owl::login and owl::auth to legacy variables populated for format_msg.
218        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
219        Add base methods for login_host and login_tty
220                and others that return undef.
221        New API for perl message formatting functions. 
222                Legacy variables are still supported for owl::format_msg
223                and owl::receive_msg, but these functions are now also
224                passed an owl::Message object which contains methods
225                for accessing the contents of the message.  See perlwrap.pm
226                (and docs TBD) for the available methods.
227                *** WARNING:  The exact API for owl::Message has
228                *** not yet stabilized.
229        Added "style" command for creating new styles.
230                Usage:  style <name> perl <function_name>
231        Added support for "show styles".  Changed global style table
232                from list to dictionary.
233        Changed AIM password prompt from "Password:" to "AIM Password:".
234        Messages are reformatted after a window resize to allow styles
235                to take into account the width of the window.
236        When perl throws an error, the message is put in the msgwin
237                if possible.
238        Added perl functions for:       
239                owl::getcurmsg() -- returns an owl::Message object for
240                                    the active message
241                                    in the current view.
242                owl::getnumcols() -- returns the column width of the window
243                owl::zephyr_getrealm() -- returns the zephyr realm
244                owl::zephyr_getsender() -- returns the zephyr sender
245        Made owl::COMMAND("foo"); be syntactic sugar for
246                owl::command("COMMAND foo");
247        Added perlwrap.pm to contain perl code to be compiled into
248                the binary.  This is transformed into perlwrap.c by
249                encapsulate.pl.
250        Renamed readconfig.c to perlconfig.c and changed variables accordingly.
251        Minor bugfixes in cmd.c and commands.c

292        Implemented styles, including the 'default' 'basic' and 'oneline'
293          styles.  A 'perl' style is available if a format_msg() function
294          is found in .owlconf
295        Added the 'default_style' variable
296        Added the 'toggle-oneline' command
297        The 'o' key is bound to 'toggle-oneline'
298        Internally, the one view now has a name, 'main', and message
299          recalcuations are done in place when its filter is changed.
300        Added filter field 'login' which can take the values 'login'
301           'logout' or 'none'

338          leading and trailing newlines from incoming messages.
339        Fixed a case sensitivity probelm in owl_message_is_personal and
340           owl_message_is_private
341        The message object now uses a list of attributes internally, in
342          prep. for supporting new messaging protocols
343        owl_function_info now uses fmtext instead of one staticly sized
344          buffer
345        in owl_message_get_cc() require that the colon be present after
346          cc.
347        Added some defenses against resize crashes, and put in debug
348          messages if they're encountered
349        In filters 'true' and 'false' are now valid tokens.
350        The 'all' filter has been redefinied to be 'true' and there is a
351          'none' filter defined as 'false'
352        Fixed bug in 'unsub' command that could cause file corruption
353        In the zlist function, give a more detailed error message if
354          the file cannot be opened.
355        Renamed old instances of zsig_exec in the code to zsigproc

357        Added a 'loadloginsubs' command to load login subscriptions from a

368        loadsubs and loadloginsubs only print messages if in interactive
369          mode

372          will be executed when new messages arive that match the
373          alert_filter
374        added the 'term' command which takes the 'raise' and 'deiconify'
375          options.  It assumes xterm for now.
376        only 'make distclean' will nuke core and ~ files now
377        fixes to owl_function_do_newmsgproc from Stephen
378        converted functions.c to new code style, which I'm giving a shot
379        Makefile.in: define DATADIR, for default owlconf.
380        Makefile.in: provide "all" and "install" rules.
381        configure.in: try also libdes and libkrb4, for people using heimdal
382        configure.in: see if des_ecb_encrypt is already prototyped.
383        configure.in: minor changes to work with new autoconf without needing acconfig.h.
384        configure.in: find the install program.
385        configure.in: test for use_default_colors since some versions of
386          solaris don't have it, so we can at least compile something
387          vaguely working there.
388        keypress.c: ifdefs for keys not defined on at least some solarises.
389        owl.c: don't call use_default_colors if we don't have it
390        readconfig.c: added *commented out* code to try to find a
391          system-default owlconf if the user doesn't have one.  Have to
392          ponder if I want this
393        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
394          des.h.
395        zcrypt.c: include owl.h so we get the configure-generated config.h
396        Change to codelist.pl to deal with new code style
397        Remove some ancient stuff from zcrypt.c
398        General cleanup to Makefile.in
399        CTRL and META are now OWL_CTRL and OWL_META.  OWL_CTRL moved to
400          keypress.c
401        do_encrypt declaired static
402        if we don't have des functions, do not try to build in zcrypt
403        kill the newmsgproc function on exit

405        Added basic AIM support, including the "aimlogin", "aimwrite" and
406           "aimlogout" commands
407        New built-in filters 'aim' and 'zephyr'.
408        Do ZResetAuthentication() before zlog_in and zlog_out as well.
409        Print AIM login / logout notifications
410        The 'alist' command prints a list of aim buddies logged in
411        The 'blist' command prints users from all protocols
412        The 'l' key is now bound to 'blist' instead of 'zlist'

414          WORK yet
415        Removed a bit of faim code that allowed commands to be executed.
416        The 'B' key is now bound to 'alist'
417        Added the 'startup' and 'unstartup' commands
418        The $HOME/.owl directory is created on startup if it does not exist
419        Added the 'aim_ingorelogin_timer' variable

423           also prints all message attributes
424        AIM logging (both in and out) now works
425        Disabled 'addbuddy' and 'delbuddy' for aim since it doesn't work yet

431       
4321.2.7
433        Outgoing messages now go through the config for formatting
434        Zaway now makes an outgoing message, instead of an admin message
435        The 'zlocate' command can now handle multiple users
436        The simple user format for "To:" is in effect again
437        Prettyed up the zwrite line for using 'reply' on a zaway

440        Fixed a memory bug in getsubs
441        Added receive support for zcrypt messages
442        Added the 'zcrypt' variable which controls whether or not zcrypt

451        Added search, '/' and '?' to basic help.
452        Will attempt to keep the current message as close as possible
453             to the previous current message after an expunge.
454        "set <variable>" and "unset <variable>" now work for boolean variables.

463        Patch to fix memory bug in replying to CC messages
464        If we're on Athena and have static krb (or other) libraries, use
465          them
466        Added "athstatic" program to the release, which handles the above
467        Cast to an int for isspace, to make gcc -Wall quiet
468        Added 'zlist' and 'l' to basic help.
469

472             'tty' variable before setting the zlocation
473        There is now a 'zlist' command that acts like 'znol -l'

480        The built-in personal filter is updated to do so
481        Fixed a bug in moving the pointer after an expunge
482        Fixed up the normal scrolling code.  Now it should always
483          land on a message, but it's still not optimal.
484        Added the variable 'smartstrip' which will strip kerberos
485          instances out for the 'reply' command.
486        Added -R/usr/athena/lib to the build for Athena
487        Started updating the intro document
488        Small changes to help / about
489        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
490          update .zephyr.subs by default.  If either is given the '-t'
491          (for "temporary") option the .zephyr.subs will not be updated
492        Turned off beeping for hitting the top or bottom of the list of
493          messages
494        Made daemon.webzephyr a special case for smartstrip
495        Added 'out' as a default filter for outgoing messages
496       
4971.2.3
498        Added filters "ping", "auto" and "login" by default.
499        Added "body" as a valid field to match on in a filter.
500        Temporary fix to bug where C-SPACE would cause the key handler to
501             lock up.
502        Messages now have a direciton (in, out or none).  Filters can
503             match on this direction
504        Outbound messages are no longer type 'admin' but are of the
505             appropriate message type (i.e. 'zephyr') and are direction
506             'out'.
507        Smartnarrow now works on outgoing messages
508        'info' updated to show more information for admin and outgoing
509             messages
510        Renamed pretty_sender to short_zuser and renamed long_sender to
511             long_zuser
512        Moved zsig generation to the zwrite object
513        Print the zsig used for outgoing messages
514        The tty variable now controls the zephyr location tty name
515       
5161.2.2
517        Added the 'search' command.
518        '/' is a keybinding for 'search'
519        '?' is a keybinding for 'search -r'
520        Fixed stristr, which was completely broken
521        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
522             and put it in functions.c
523        Attempts to stay near the current message when switching views.
524             When switching from an empty view to one we've previously
525             been in, the new current message position will attempt
526             to be close to the current position from the last
527             time we visited that view.
528        Fixed bug in readconfig.c that prevented building under perl 5.005.
529        Switched "C-x C-x" to only "startcommand quit"
530        'getsubs' prints closer to the order you sub in.
531        Modified the behavior of last so that "> >" will clear the screen.
532        The new behavior of last is:
533              Moves the pointer to the last message in the view.
534              If we are already at the last message in the view,
535              blanks the screen and moves just past the end of the view
536              so that new messages will appear starting at the top
537              of the screen.
538        Fixed a typo in the help for smartzpunt.
539        Fixed functions to handle curmsg being past the end of the view.
540
5411.2.1
542        New framework for command handling.
543        New framework for keymap handling.
544        Added commands for everything that is bound
545             to a key (do 'show commands' to get the full list).
546        Added 'multi' and '(' commands to allow multiple commands
547             to be specified on a line.             
548        Added user keybindings with bindkey command.
549        Added command aliases (eg, "alias foo bar").
550        Added undelete command that parallels the delete command.
551        Added additional options to delete command.
552        The reply command now takes arguments.
553        Added 'edit:insert-text' command.
554        Added 'show zpunts' to show active punt filters.
555        Added 'show variable <name>' and 'show variables'.
556        Added 'show command <name>' and 'show commands'.
557        Added 'show keymap <name>' and 'show keymaps'.
558        Added 'M-u' to undelete all messages in current view.
559        Fixed dotsend so that the zephyr will still send if there
560             is whitespace after the dot but not on the same line.
561             This should resolve an issue where dotsend wouldn't work
562             if you'd gone up and edited a zephyr.
563        Bug in page down fixed
564        C-t will transpose characters
565        Fix the scrolling bug where we would sometimes fail to scroll
566             the screen down, leaving the current message off
567             the bottom of the screen.
568        Refixed 'login or login' typo in help
569        Fixed M-u description
570        Removed 'first' and 'last' from basic command help
571        Added M-N to basic key help
572        Added M-D, M-u to basic key help
573        Fixed a quoting problem in configure.in
574        Changed top of help to use 'show' instead of M-x
575        Fixed a bug in the summary field for user-created aliases
576        Added "reply zaway" which sends a zaway response to the current msg.
577        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
578        Some buffer overruns fixed
579        Variables now have a summary and a long description.
580                Only the summary is shown with help.
581                The long description is shown with "show variable foo".
582        Added a 'scrollmode' variable which determines how the screen
583             will scroll as the cursor moves.  The default behaves
584             identically to previous versions of owl.
585             The following modes are supported:
586             normal      - This is the owl default.  Scrolling happens
587                           when it needs to, and an attempt is made to
588                           keep the current message roughly near
589                           the middle of the screen.  (default)
590             top         - The current message will always be the
591                           the top message displayed.
592             neartop     - The current message will be one down
593                           from the top message displayed,
594                           where possible.
595             center      - An attempt is made to keep the current
596                           message near the center of the screen.
597             paged       - The top message displayed only changes
598                           when user moves the cursor to the top
599                           or bottom of the screen.  When it moves,
600                           the screen will be paged up or down and
601                           the cursor will be near the top or
602                           the bottom.
603             pagedcenter - The top message displayed only changes
604                           when user moves the cursor to the top
605                           or bottom of the screen.  When it moves,
606                           the screen will be paged up or down and
607                           the cursor will be near the center.
608        Added owl_sprintf which returns the formatted string, or NULL.
609                The caller must free this string.
610                This will allocate enough memory and thus
611                avoid potential some buffer overrun situations.
612        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
613                message as having been sent.)
614        The "Not logged in or subscribing to messages" error
615                now includes the name of the recipient.
616        The "disable-ctrl-d" variable may also be set to "middle"
617                which will result in ctrl-d only sending at the
618                end of the message.  This is now the default.
619                This also added a command "editmulti:done-or-delete".
620        Fixed a bug in the "reply -e" command.
621        Always clear the command buffer before executing the command.
622                (So that interactive commands can sanely do start-command.)
623        Fixed preservation of e->dotsend across owl_editwin_clear().
624        Added history for multiline edit windows (eg, for zephyr composition).
625                The M-n and M-p keys will cycle through the history ring.
626                In particular, it is now possible to edit the command line
627                of a zephyr being composed:  C-c it and restart it
628                and then M-p to get the aborted composition back.
629        Added owl::send_zwrite(command, message) to the perl glue
630                to allow for the direct sending of multi-line messages.
631                For example:  owl::send_zwrite("-c foo -i bar", "hello");
632        Changed owl_fmtext_print_plain to return an alloc'd string to
633                avoid buffer overrun risks.
634        Added owl::ztext_stylestrip("...") function to perlglue
635                 which returns the ztext with formatting stripped out.
636        Added colorztext variable which can be used to disable @color()
637                 strings arriving in messages after it is set.
638                 (Currently, changing its value won't reformat messages).
639        Outgoing zephyr logging now obeys the logpath variable.
640        The '~' character in logpath and classlogpath now gets
641                 replaced with the user's home directory.
642        Added simple implementation of smartnarrow-to-admin that
643                 creates a "type-admin" autofilter.
644                 This was done mostly so that M-C-n and M-C-p do something
645                 sane on admin messages.
646        Added opera to the allowed options to the webbrowser variable.
647        Fixed some buffer overruns in the "reply" command.
648        When repying to "all" on a message that begins with "CC:" (eg, sent
649                 with "zwrite -C", the reply line will be constructed
650                 from the sender and the usernames on the CC: line
651                 of the message being replied to.
652        There is no such thing as C-R, so left C-r as it is but added:
653                 M-r --- edit reply to all
654                 M-R --- edit reply to sender
655        Added RCS Id strings to all files.
656        'show keymaps' shows details of all keymaps after summary list.
657        Added --no-move option to delete command.
658                In particular, delete-and-always-move-down may now
659                be implemented with
660                '( delete --no-move ; next --skip-deleted )'.
661        Folded the nextmsg and prevmsg commands and functions together into
662                one command which takes arguments.
663                Added '--filter <name>' option (eg, for next_personal),
664                '--skip-deleted' option, and
665                '--last-if-none'/'--first-if-none' options.
666                Help updated accordingly. 
667                In particular, the 'personal' filter is now used
668                for 'next personal'. 
669                Added --smart-filter and --smart-filter-instance options
670                to the next and prev commands.
671        Updated examples/owlconf.erik with the above.
672        Made owl_function_fast*filt return a string and not do the
673                narrowing, to make it more general.
674        Added a smartfilter command that creates a filter
675                based on the current message and returns the name
676                of the filter.
677        Added M-C-n and M-C-p keybindings to "move to next message
678                matching current" and "move to previous message
679                matching current"
680        Added variables edit:maxfillcols and edit:maxwrapcols which
681                will limit how wide editing paragraphs may get before
682                they get wrapped.  This is a max and may be narrower
683                depending on the current size of the window.
684                If 0, the max is unlimited.  Default is 70 columns for
685                edit:maxfillcols and unlimited for edit:maxwrapcols.
686        Added smartzpunt command with key binding of "C-x k".
687                This starts a zpunt command filled in with
688                the proposed zpunt.
689        Fixed a memory reference bug in delete and undelete commands.
690        Added support for perl to call directly back into owl.
691        Changed the implementation of owl::command("...") to immediately
692                call back into owl.  This allows perl to get the return
693                value of strings returned by owl commands.
694        Added the getview command which returns the name of the current
695                view's filter. 
696        Added the getvar command which returns the value of a variable.
697        Added an example to examples/owlconf.erik which uses TAB to
698                narrow and restore the view. 
699        Added an example to examples/owlconf.erik which uses M-c to
700                color messages matching the current one green.
701        Integrated change to fix problem with popup blinking on new zephyrs.
702        C-l and resizes will now refresh an open viewwin (eg, help).
703        Updated doc/code.txt to include info about filters, commands,
704                contexts, and keybindings.
705        Exec commands cleaned up to not have buffer-size limitations
706                and to not mess up spaces.  exec also returns a string
707                of the output now.
708        Integrated changes from 1.1.3, and added docs for "zlocate -d"
709                and new show commands.
710        Show with arguments produces help on show.
711        Fix a bug in readconfig caught by efence (where we'd try to read before
712                the beginning of a string if it was empty).
713        The perl command doesn't do makemsg directly, but instead
714             returns the string and it will get printed if it
715             was run interactively.
716       
7171.1.3
718        'show subs' and 'show subscriptions' are now the same as 'getsubs'
719        zlocate now takes an optional -d argument
720        'show terminal' / 'show term'
721        '>' / last doesn't set the last message at the top of the screen now

723        include 'default' in the 'show colors' list
724        added help for 'zpunt' and 'zunpunt'
725        changed the bug address in the startup message
726        can now do 'show status'
727        can now do 'show version'
728        'status' / 'show status' includes the owl version number now
729        'show terminal' includes whether the terminal can change colors
730        fixed off by one bugs in paging / scrolling viewwin
731        don't downcase the sender when getting the log name for personals
732        support @owl::fields as well as @fields
733        downcase class/inst filter names in auto filters
734
7351.1.2
736        Fixed memory mishandling bug
737        Fixed bug in redfining the filter attached to the current view
738        M-n will narrow to message, instance on non-personal, class
739             MESSAGE messages
740        M-N behavies like M-n except that on class messages it narrows
741            to class and instance
742        line wrap earlier, to account for tabbing
743        fixed typo in help
744        'status' command now displays info on terminal color support
745        zephyr @ formatting is now case independant
746        added support for color terminals

748        'D' for deleted messages is now not bold, unless it's the current
749          message
750        F1 displays the help screen
751        added filter colors
752        added the 'colorview' command
753        added the 'show colors' command
754        users who don't have a .zephyr.subs get a simpler format for
755          incoming messages
756        If colors are available 'show filters' will show a filter in the
757          color associated with it.
758        Added the zpunt and zunpunt commands
759        Lines in the subs file starting with '-' are zpunted
760        Include login/logout messages in auto user filters
761        'V' changes to the home view ('all' by default)
762       
7631.1.1
764        Fixed perl, aperl, and pperl commands to deal with quoting
765              and spaces in a saner manner.
766        Removed all owl_get_* methods for booleans and switched
767              cases where they were used to owl_is_*
768        Changes to owlconf.erik to use some new features.
769        Increased the size of the help buffer (as it
770              was overflowing and truncating the help message).
771        Variables prefixed with a _ are not shown in help
772              or by printallvars (and prefixed Not Yet Implemented
773              variables with this).
774        Fix typo in help
775        include stdio.h in functions.c
776        remove stale "q to quit" from bottom of info message

838              a string not ending in a newline
839        Added 'X' keybinding which expunges and then switches to

858              and the owl_dict type.

860        Overhaul/rewrite of variable handling.  Variables are now managed
861              in an owl_vardict (in g.vars) which contains a dictionary
862              of owl_variable's.  Each owl_variable has dispatch functions
863              for validating values, setting it and getting it,
864              and for setting it to and from string values.
865              The variable.c file contains the list of variables.
866              Stubs for the owl_global_<varname>_get functions and friends
867              are generated from variable.c by stubgen.pl.
868              The help.c messages for variables now calls into variable.c
869              so all information about most variables is in one place.

875              to running owl_function_printallvars.
876        debug is now a variable that can be turned on and off.
877        Fixed mail,inbox message parsing in examples/owlconf.erik
878        Made zaway_msg and zaway_msg_default into variables
879        Changed owl_function_makemsg and owl_function_debugmsg
880               to use varargs (ie, so they can now take a format
881               string with args).
882        Don't allow " and \ characters in URLs with the "w" command.
883        Removed lots of build warnings.

891        Added appendtosepbar variable which may contain text which will
892              be appended to the sepbar.  This allows the configfile
893              to put information about pings and logins into
894              the sepbar.  (It may be worth also providing a variable
895              which enables this by default, but for now this allows
896              for experimenting with what works well.)
897        Added doc/code.txt which gives a brief overview of the code.
898        Added tags makefile rule and added TAGS to distclean rule.
