36        Only use resizeterm() if it's available
37        Debian backports
38        Change license to GPLv3
41        Don't crash doing zlocate with bad tickets. [BZ 12]
42        Metion the path for the owlconf in intro.txt [BZ 54]
43        Print better error message if startup fails due to unreadable
44           .owlconf [BZ 57]
45        In load-subs: Print an error message if the file is unreadable or
46          doesn't exist, UNLESS load-subs is called with no arguments.  In
47          that case only print an error if the file exists but isn't
48          readable.  Still prints an error either way if zephyr reports a
49          failure. [BZ 19]
50        Fixed some small memory leaks in logging if files unwriteable
51        If the variable logfilter is set it names a filter.  Any messages
52          matching this filter are logged.  This is an independent
53          mechanism from the other logging variables.  If you want to
54          control all logging with logfilter the other variables must be
55          set to their default (off) settings. [BZ 37]
56        Relatively substantial changes made under the hood to support
57          filter logging.  Now have more consistent interfaces to
58          creating messages etc.  Still needs more work though.
59        Deal gracefully with being resized as small as 1x1 [BZ 3]
62        Fix a new problem finding libdes425
63        Don't crash on very long hostnames [BZ 52]
64        In 'sub' command, create .zephyr.subs if it doesn't exist [BZ 15]
65        A fix for certain resize crashes (partly from alexmv) [BZ 55]
66        Turn off ISTRIP (gildea)
69        Include /usr/include/kerberosIV if it's found
72        Do OLC formatting for anything coming from olc.matisse
73        Improvements to popup size algorithm (from gildea)
74        Improved 'show colors' with non-colored labels
77        The colorclass command is added, to make colorization easy
78        Handle MIT Athena OLC zephyrs correctly
79        Updated ktools website / bug address
80        Do ntohs() when printing zephyr port in zephyr info
81        Updated man page
84        Fixed three bugs found by Valgrind.
85        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
86          would cause a segfault.
87        pexec will now incrimentally display data as it is output
88          by the child process.  Additionally, commands running under
89          pexec may now be killed by quitting out of the popless window.
90        Added muxevents select loop dispatcher.  File descriptors may
91          be registered with muxevents and handlers will be dispatched
92          to when data is available for non-blocking read/write/except.
93        Switched the stderr_redir stuff to use muxevents.
94        Print C-\ correctly (from gildea)
95        Dropped first brace in muxevents functions for consistency
96        Catch SIGHUP and SIGTERM and do a proper logout
99        Added a licence
100        The 'personalbell' variable can now be set to 'on' 'off' or
101          the name of a filter to match against
102        The 'loglogins' variable now controls whether login/logout
103          messages are logged.  It is off by default.  For now this
104          affects only AIM messages, later zephyr login/logout messages
105          will also be logged if this is set to 'on'
106        Added 'show license'
109        Normalize and downcase AIM names for logging
110        Fixed a bug where sending a null zsig could cause a crash
111        Better 'away' toggling if only one protocol is away.
114        Added perl filter elements.  Similar to having "filter <subfilter>"
115          in a filter, you may also have "perl <functionname>"
116          where <functionname> is passed an owl::Message object and
117          returns 0 or 1 depending on whether the message matches
118          that element of the filter.
119        Don't print an error about loading subs if there is no
120          .zephyr.subs
121        Do the initial zephyr_buddy_check when pseduologin set to true.
122        Updated man page
125        removed unused filter_depth variable
126        Fixed memory bug on receiving pings
129        Filters of filters now work.
130        Removed the "possibly not readable" part of the config parsing
131          error
132        In the sepbar, reverse video the view name when it's not set to
133          view_home (as opposed to the static 'all').
134        The '!' key (bound to 'view -r') now creates a negative version of
135          the current view and switches to it.  i.e. "show me all the
136          messages that are not these"
137        Added the 'ignorelogins' variable
138        Log when outgoing personal message fails
139        Removed file descriptor from sigpipe catcher printer just for now,
140          since the field does not exist on OSX
141        Added an ifndef for socklen_t in libfaim/ft.c
142        Added the 'aim search' command.  The popup on callback may be
143          dangerous, should switch to an admin msg for results, or add a
144          new event queue
145        First pass at AIM away messages.  It is a little different from
146          what most clients seem to do, in that an away reply is sent for
147          each message received.  Most clients only reply to the first one
148          per away-session.
149        Now have a set of 'aaway' commands and variables just like the
150          'zaway' ones (except that changing the 'aaway' variable talks to
151          the server)
152        The new 'away' command does everything for both AIM *and* zephyr.
153          There is a known funkiness here, where if you turn one away on,
154          and then use 'away' (or 'A') to toggle, you will turn on off and
155          the other on.  Just leaving it for now.  Should do better in the
156          next patch.
157        The 'A' key is bound to 'away'
158        Status bar can now read AWAY, Z-AWAY or A-AWAY.
159        Changed C-n to scroll down just a line in popless
160        If the config exists but is not readable, print an error before
161          exiting
162        Only print forced AIM logout message once.
163        Don't bind F1 to help in edit context
164        Fix bug in 'getsubs' with no tickets
165        New code for getting users from .anyfile
166        Added the 'pseudologins' variable, and code to do it
167        new attributes 'pseudo' 'logintty' and 'loginhost'
168        Don't print extra new lines in popless_file
169        New zephyr_get_field function
172        Fixed missing word in startup message
173        Better 'status' command
174        Use '+' for popwin corners when 'fancylines' is off
175        Allow TERMINFO to be overridden in the envrionment
176        Command line arg -D turns on debugging and deletes previous
177          debugging file
178        Do ~ expansion in 'dump' command.
179        Current directory added to 'status' command
180        Massive changes to libfaim and aim
183        Changed startup message for new mailing list
184        blist now prints AIM info even if .anyone is unreadable
185        Catch SIGPIPE and print an error rather than crashing.
186                [It's possible that this may have some portability
187                issues under Solaris and we may need to add some
188                configure stuff around SA_SIGINFO...]
189        Handle the case in aim_bstream_send where aim_send returns -1,
190                although there is likely an underlying problem here
191                that would lead to this case.
192        Print the username on aim login failure, not something random like
193                the password.  ;)
194        Un-word-wrap text when sending AIM messages.
195        Replace the main loop continue in the keyboard handler with an else.
198        Command history now doesn't allow the last entry
199           to be repeated
200        If format_msg returns "" print "<unformatted message>"
201        Better align oneline admin and loopback messages
202        Print an admin message indicating when subscriptions can
203           not be loaded on startup
204        Set aim_ignorelogin_timer to 15 by default
205        Admin message on login/logout of AIM
206        Fixed double quoting in smartzpunt
207        Added timestamp to login/logout messages
208        Fixed replies to loopback messages
209        Fixed smartnarrow on classes/instances with spaces
210        Added the 'loggingdirection' variable
211        All loopback messages log to 'loopback' now
212        Print an error message if trying an invalid color for a filter
213        Fixed bug causing > not to go to end of editwin every time
216        Updated basic help
217        Display CC: in outgoing CC messages
218        More AIM logout detection
219        Don't proclaim "interfaces changed" on first build.
220        Added the 'loopback' message type
221        Added the 'loopwrite' command
222        Added a timestamp to the default style
223        Zpunt now works with weird regex characters
224        Smart filters now work with weird regex characters
227        Allow 'hostname' in filters.
228        Fixed bug in reporting when no one is subbed to a class
229        Added an extral newline in logging incoming zephyrs
230        An admin message is displayed when you are logged out of AIM
231        Print an error message and admin message if an AIM send fails
234        Added the 'fancylines' variable.
235        Added the 'show startup' command.
236        Added feature for capturing stderr messages

238        Create an admin message explaning that a zephyr couldn't
239           be sent
240        Better reporting of perl errors (both into the errqueue
241                and also clearing the error after displaying it).
242        Allow default_style to be specified in config.
243        Added errqueue
244        Added command "show errors"

254        Add owl::login and owl::auth to legacy variables populated for format_msg.
255        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
256        Add base methods for login_host and login_tty
257                and others that return undef.
258        New API for perl message formatting functions. 
259                Legacy variables are still supported for owl::format_msg
260                and owl::receive_msg, but these functions are now also
261                passed an owl::Message object which contains methods
262                for accessing the contents of the message.  See
263                (and docs TBD) for the available methods.
264                *** WARNING:  The exact API for owl::Message has
265                *** not yet stabilized.
266        Added "style" command for creating new styles.
267                Usage:  style <name> perl <function_name>
268        Added support for "show styles".  Changed global style table
269                from list to dictionary.
270        Changed AIM password prompt from "Password:" to "AIM Password:".
271        Messages are reformatted after a window resize to allow styles
272                to take into account the width of the window.
273        When perl throws an error, the message is put in the msgwin
274                if possible.

276                owl::getcurmsg() -- returns an owl::Message object for
277                                    the active message
278                                    in the current view.
279                owl::getnumcols() -- returns the column width of the window
280                owl::zephyr_getrealm() -- returns the zephyr realm
281                owl::zephyr_getsender() -- returns the zephyr sender
282        Made owl::COMMAND("foo"); be syntactic sugar for
283                owl::command("COMMAND foo");
284        Added to contain perl code to be compiled into
285                the binary.  This is transformed into perlwrap.c by
287        Renamed readconfig.c to perlconfig.c and changed variables accordingly.
288        Minor bugfixes in cmd.c and commands.c
289        Improved intro doc
292        Idletimes now appear in the buddylisting
293        Failed AIM logins are now correctly reported

384        Added some defenses against resize crashes, and put in debug
385          messages if they're encountered
386        In filters 'true' and 'false' are now valid tokens.
387        The 'all' filter has been redefinied to be 'true' and there is a
388          'none' filter defined as 'false'
389        Fixed bug in 'unsub' command that could cause file corruption

407        added the 'alert_filter' variable, defaults to 'none'.
408        added the 'alert_action' variable, which is an owl command that
409          will be executed when new messages arive that match the
410          alert_filter
411        added the 'term' command which takes the 'raise' and 'deiconify'
412          options.  It assumes xterm for now.
413        only 'make distclean' will nuke core and ~ files now
414        fixes to owl_function_do_newmsgproc from Stephen

420 minor changes to work with new autoconf without needing acconfig.h.
421 find the install program.
422 test for use_default_colors since some versions of

424          vaguely working there.
425        keypress.c: ifdefs for keys not defined on at least some solarises.
426        owl.c: don't call use_default_colors if we don't have it
427        readconfig.c: added *commented out* code to try to find a
428          system-default owlconf if the user doesn't have one.  Have to

430        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
431          des.h.
432        zcrypt.c: include owl.h so we get the configure-generated config.h
433        Change to to deal with new code style
434        Remove some ancient stuff from zcrypt.c
435        General cleanup to
436        CTRL and META are now OWL_CTRL and OWL_META.  OWL_CTRL moved to
437          keypress.c
438        do_encrypt declaired static
439        if we don't have des functions, do not try to build in zcrypt
440        kill the newmsgproc function on exit

447        The 'alist' command prints a list of aim buddies logged in
448        The 'blist' command prints users from all protocols
449        The 'l' key is now bound to 'blist' instead of 'zlist'
450        Started work on 'addbuddy' and 'delbuddy' command but they DO NOT
451          WORK yet
452        Removed a bit of faim code that allowed commands to be executed.
453        The 'B' key is now bound to 'alist'
454        Added the 'startup' and 'unstartup' commands
455        The $HOME/.owl directory is created on startup if it does not exist
456        Added the 'aim_ingorelogin_timer' variable

459        improved 'info' function lists seperate info for zephyr, aim and
460           also prints all message attributes
461        AIM logging (both in and out) now works
462        Disabled 'addbuddy' and 'delbuddy' for aim since it doesn't work yet
463        Hacked the Perl build stuff not to link with iconv
466        Class pings are displayed differently now
467        Updated owlconf.simple example to format outgoing messages.
470        Outgoing messages now go through the config for formatting
471        Zaway now makes an outgoing message, instead of an admin message
472        The 'zlocate' command can now handle multiple users
473        The simple user format for "To:" is in effect again
474        Prettyed up the zwrite line for using 'reply' on a zaway
475        Added a workaround for a libzephyr bug that caused zwrites to fail

487          Don't use it.
488        Added search, '/' and '?' to basic help.
489        Will attempt to keep the current message as close as possible
490             to the previous current message after an expunge.
491        "set <variable>" and "unset <variable>" now work for boolean variables.

509             'tty' variable before setting the zlocation
510        There is now a 'zlist' command that acts like 'znol -l'
511        'l' is bound to 'zlist'
512        Fixed memory leak uninitialzed memory read in fmtext
513        viewwin will now say "End" instead of "More" when at the end

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

898              in an owl_vardict (in g.vars) which contains a dictionary
899              of owl_variable's.  Each owl_variable has dispatch functions
900              for validating values, setting it and getting it,
901              and for setting it to and from string values.
902              The variable.c file contains the list of variables.
903              Stubs for the owl_global_<varname>_get functions and friends
904              are generated from variable.c by

930              to put information about pings and logins into
931              the sepbar.  (It may be worth also providing a variable
932              which enables this by default, but for now this allows
933              for experimenting with what works well.)
934        Added doc/code.txt which gives a brief overview of the code.
