71        owl_function_info now uses fmtext instead of one staticly sized
72          buffer
73        in owl_message_get_cc() require that the colon be present after

100          will be executed when new messages arive that match the
101          alert_filter
102        added the 'term' command which takes the 'raise' and 'deiconify'
103          options.  It assumes xterm for now.
104        only 'make distclean' will nuke core and ~ files now

112 find the install program.

117        owl.c: don't call use_default_colors if we don't have it
118        readconfig.c: added *commented out* code to try to find a
119          system-default owlconf if the user doesn't have one.  Have to

127        CTRL and META are now OWL_CTRL and OWL_META.  OWL_CTRL moved to
128          keypress.c
129        do_encrypt declaired static
130        if we don't have des functions, do not try to build in zcrypt
131        kill the newmsgproc function on exit

150        improved 'info' function lists seperate info for zephyr, aim and
151           also prints all message attributes
152        AIM logging (both in and out) now works
153        Disabled 'addbuddy' and 'delbuddy' for aim since it doesn't work yet

178          Don't use it.
179        Added search, '/' and '?' to basic help.
180        Will attempt to keep the current message as close as possible
181             to the previous current message after an expunge.

200             'tty' variable before setting the zlocation
201        There is now a 'zlist' command that acts like 'znol -l'
202        'l' is bound to 'zlist'

208        The built-in personal filter is updated to do so
209        Fixed a bug in moving the pointer after an expunge
210        Fixed up the normal scrolling code.  Now it should always
211          land on a message, but it's still not optimal.
212        Added the variable 'smartstrip' which will strip kerberos
213          instances out for the 'reply' command.
214        Added -R/usr/athena/lib to the build for Athena
215        Started updating the intro document
216        Small changes to help / about
217        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
218          update .zephyr.subs by default.  If either is given the '-t'
219          (for "temporary") option the .zephyr.subs will not be updated
220        Turned off beeping for hitting the top or bottom of the list of
221          messages
222        Made daemon.webzephyr a special case for smartstrip
223        Added 'out' as a default filter for outgoing messages
226        Added filters "ping", "auto" and "login" by default.
227        Added "body" as a valid field to match on in a filter.
228        Temporary fix to bug where C-SPACE would cause the key handler to
229             lock up.
230        Messages now have a direciton (in, out or none).  Filters can
231             match on this direction
232        Outbound messages are no longer type 'admin' but are of the
233             appropriate message type (i.e. 'zephyr') and are direction
234             'out'.
235        Smartnarrow now works on outgoing messages
236        'info' updated to show more information for admin and outgoing
237             messages
238        Renamed pretty_sender to short_zuser and renamed long_sender to
239             long_zuser
240        Moved zsig generation to the zwrite object
241        Print the zsig used for outgoing messages
242        The tty variable now controls the zephyr location tty name
245        Added the 'search' command.
246        '/' is a keybinding for 'search'
247        '?' is a keybinding for 'search -r'
248        Fixed stristr, which was completely broken
249        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
250             and put it in functions.c
251        Attempts to stay near the current message when switching views.
252             When switching from an empty view to one we've previously
253             been in, the new current message position will attempt
254             to be close to the current position from the last
255             time we visited that view.
256        Fixed bug in readconfig.c that prevented building under perl 5.005.
257        Switched "C-x C-x" to only "startcommand quit"
258        'getsubs' prints closer to the order you sub in.
259        Modified the behavior of last so that "> >" will clear the screen.
260        The new behavior of last is:
261              Moves the pointer to the last message in the view.
262              If we are already at the last message in the view,
263              blanks the screen and moves just past the end of the view
264              so that new messages will appear starting at the top
265              of the screen.
266        Fixed a typo in the help for smartzpunt.
267        Fixed functions to handle curmsg being past the end of the view.
270        New framework for command handling.
271        New framework for keymap handling.
272        Added commands for everything that is bound
273             to a key (do 'show commands' to get the full list).
274        Added 'multi' and '(' commands to allow multiple commands
275             to be specified on a line.             
276        Added user keybindings with bindkey command.
277        Added command aliases (eg, "alias foo bar").
278        Added undelete command that parallels the delete command.
279        Added additional options to delete command.
280        The reply command now takes arguments.
281        Added 'edit:insert-text' command.
282        Added 'show zpunts' to show active punt filters.
283        Added 'show variable <name>' and 'show variables'.
284        Added 'show command <name>' and 'show commands'.
285        Added 'show keymap <name>' and 'show keymaps'.
286        Added 'M-u' to undelete all messages in current view.
287        Fixed dotsend so that the zephyr will still send if there
288             is whitespace after the dot but not on the same line.
289             This should resolve an issue where dotsend wouldn't work
290             if you'd gone up and edited a zephyr.
291        Bug in page down fixed
292        C-t will transpose characters
293        Fix the scrolling bug where we would sometimes fail to scroll
294             the screen down, leaving the current message off
295             the bottom of the screen.
296        Refixed 'login or login' typo in help
297        Fixed M-u description
298        Removed 'first' and 'last' from basic command help
299        Added M-N to basic key help
300        Added M-D, M-u to basic key help
301        Fixed a quoting problem in
302        Changed top of help to use 'show' instead of M-x
303        Fixed a bug in the summary field for user-created aliases
304        Added "reply zaway" which sends a zaway response to the current msg.
305        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
306        Some buffer overruns fixed
307        Variables now have a summary and a long description.
308                Only the summary is shown with help.
309                The long description is shown with "show variable foo".
310        Added a 'scrollmode' variable which determines how the screen
311             will scroll as the cursor moves.  The default behaves
312             identically to previous versions of owl.
313             The following modes are supported:
314             normal      - This is the owl default.  Scrolling happens
315                           when it needs to, and an attempt is made to
316                           keep the current message roughly near
317                           the middle of the screen.  (default)
318             top         - The current message will always be the
319                           the top message displayed.
320             neartop     - The current message will be one down
321                           from the top message displayed,
322                           where possible.
323             center      - An attempt is made to keep the current
324                           message near the center of the screen.
325             paged       - The top message displayed only changes
326                           when user moves the cursor to the top
327                           or bottom of the screen.  When it moves,
328                           the screen will be paged up or down and
329                           the cursor will be near the top or
330                           the bottom.
331             pagedcenter - The top message displayed only changes
332                           when user moves the cursor to the top
333                           or bottom of the screen.  When it moves,
334                           the screen will be paged up or down and
335                           the cursor will be near the center.
336        Added owl_sprintf which returns the formatted string, or NULL.
337                The caller must free this string.
338                This will allocate enough memory and thus
339                avoid potential some buffer overrun situations.
340        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
341                message as having been sent.)
342        The "Not logged in or subscribing to messages" error
343                now includes the name of the recipient.
344        The "disable-ctrl-d" variable may also be set to "middle"
345                which will result in ctrl-d only sending at the
346                end of the message.  This is now the default.
347                This also added a command "editmulti:done-or-delete".
348        Fixed a bug in the "reply -e" command.
349        Always clear the command buffer before executing the command.
350                (So that interactive commands can sanely do start-command.)
351        Fixed preservation of e->dotsend across owl_editwin_clear().
352        Added history for multiline edit windows (eg, for zephyr composition).
353                The M-n and M-p keys will cycle through the history ring.
354                In particular, it is now possible to edit the command line
355                of a zephyr being composed:  C-c it and restart it
356                and then M-p to get the aborted composition back.
357        Added owl::send_zwrite(command, message) to the perl glue
358                to allow for the direct sending of multi-line messages.
359                For example:  owl::send_zwrite("-c foo -i bar", "hello");
360        Changed owl_fmtext_print_plain to return an alloc'd string to
361                avoid buffer overrun risks.
362        Added owl::ztext_stylestrip("...") function to perlglue
363                 which returns the ztext with formatting stripped out.
364        Added colorztext variable which can be used to disable @color()
365                 strings arriving in messages after it is set.
366                 (Currently, changing its value won't reformat messages).
367        Outgoing zephyr logging now obeys the logpath variable.
368        The '~' character in logpath and classlogpath now gets
369                 replaced with the user's home directory.
370        Added simple implementation of smartnarrow-to-admin that
371                 creates a "type-admin" autofilter.
372                 This was done mostly so that M-C-n and M-C-p do something
373                 sane on admin messages.
374        Added opera to the allowed options to the webbrowser variable.
375        Fixed some buffer overruns in the "reply" command.
376        When repying to "all" on a message that begins with "CC:" (eg, sent
377                 with "zwrite -C", the reply line will be constructed
378                 from the sender and the usernames on the CC: line
379                 of the message being replied to.
380        There is no such thing as C-R, so left C-r as it is but added:
381                 M-r --- edit reply to all
382                 M-R --- edit reply to sender
383        Added RCS Id strings to all files.
384        'show keymaps' shows details of all keymaps after summary list.
385        Added --no-move option to delete command.
386                In particular, delete-and-always-move-down may now
387                be implemented with
388                '( delete --no-move ; next --skip-deleted )'.
389        Folded the nextmsg and prevmsg commands and functions together into
390                one command which takes arguments.
391                Added '--filter <name>' option (eg, for next_personal),
392                '--skip-deleted' option, and
393                '--last-if-none'/'--first-if-none' options.
394                Help updated accordingly. 
395                In particular, the 'personal' filter is now used
396                for 'next personal'. 
397                Added --smart-filter and --smart-filter-instance options
398                to the next and prev commands.
399        Updated examples/owlconf.erik with the above.
400        Made owl_function_fast*filt return a string and not do the
401                narrowing, to make it more general.
402        Added a smartfilter command that creates a filter
403                based on the current message and returns the name
404                of the filter.
405        Added M-C-n and M-C-p keybindings to "move to next message
406                matching current" and "move to previous message
407                matching current"
408        Added variables edit:maxfillcols and edit:maxwrapcols which
409                will limit how wide editing paragraphs may get before
410                they get wrapped.  This is a max and may be narrower
411                depending on the current size of the window.
412                If 0, the max is unlimited.  Default is 70 columns for
413                edit:maxfillcols and unlimited for edit:maxwrapcols.
414        Added smartzpunt command with key binding of "C-x k".

418        Added support for perl to call directly back into owl.

423                view's filter.

426                narrow and restore the view.

428                color messages matching the current one green.

430        C-l and resizes will now refresh an open viewwin (eg, help).
431        Updated doc/code.txt to include info about filters, commands,
432                contexts, and keybindings.
433        Exec commands cleaned up to not have buffer-size limitations
434                and to not mess up spaces.  exec also returns a string
435                of the output now.
436        Integrated changes from 1.1.3, and added docs for "zlocate -d"
437                and new show commands.
438        Show with arguments produces help on show.
439        Fix a bug in readconfig caught by efence (where we'd try to read before
440                the beginning of a string if it was empty).
441        The perl command doesn't do makemsg directly, but instead
442             returns the string and it will get printed if it

467             MESSAGE messages

469            to class and instance

471        fixed typo in help

485          color associated with it.

488        Include login/logout messages in auto user filters
489        'V' changes to the home view ('all' by default)
492        Fixed perl, aperl, and pperl commands to deal with quoting
493              and spaces in a saner manner.
494        Removed all owl_get_* methods for booleans and switched
495              cases where they were used to owl_is_*
496        Changes to owlconf.erik to use some new features.
497        Increased the size of the help buffer (as it
498              was overflowing and truncating the help message).
499        Variables prefixed with a _ are not shown in help
500              or by printallvars (and prefixed Not Yet Implemented

589              in an owl_vardict (in g.vars) which contains a dictionary
590              of owl_variable's.  Each owl_variable has dispatch functions
591              for validating values, setting it and getting it,
592              and for setting it to and from string values.
593              The variable.c file contains the list of variables.
594              Stubs for the owl_global_<varname>_get functions and friends
595              are generated from variable.c by

608               to use varargs (ie, so they can now take a format
609               string with args).
610        Don't allow " and \ characters in URLs with the "w" command.

621              to put information about pings and logins into
622              the sepbar.  (It may be worth also providing a variable
623              which enables this by default, but for now this allows
624              for experimenting with what works well.)
625        Added doc/code.txt which gives a brief overview of the code.
626        Added tags makefile rule and added TAGS to distclean rule.
