2.0.1-pre-1
        Moved newmsgproc stuff to a function procedure
        Added the 'newlinestrip' variable, on by default, that strips
          leading and trailing newlines from incoming messages.
        Fixed a case sensitivity probelm in owl_message_is_personal and
           owl_message_is_private
        The message object now uses a list of attributes internally, in
          prep. for supporting new messaging protocols
        owl_function_info now uses fmtext instead of one staticly sized
          buffer
        in owl_message_get_cc() require that the colon be present after
          cc.
        Added some defenses against resize crashes, and put in debug
          messages if they're encountered
        In filters 'true' and 'false' are now valid tokens.
        The 'all' filter has been redefinied to be 'true' and there is a
          'none' filter defined as 'false'
        Fixed bug in 'unsub' command that could cause file corruption
        In the zlist function, give a more detailed error message if
          the file cannot be opened.
        Renamed old instances of zsig_exec in the code to zsigproc
        Don't print the stderr from zsigproc
        Added a 'loadloginsubs' command to load login subscriptions from a
          file
        Added a 'loadsubs' command to eventually phase out the 'load-subs'
          command
        Made M-n work on classes and instances with spaces in them
        Zaway now obeys the smart strip variable
        Hacked the build system to not have the -E link problem on Athena
        Added ZResetAuthentication in a number of places to fix problems
          with stale tickets
        Added some hooks for malloc debugging
        M-p is bound to 'view personal' by default
        loadsubs and loadloginsubs only print messages if in interactive
          mode
        added the 'alert_filter' variable, defaults to 'none'.
        added the 'alert_action' variable, which is an owl command that
          will be executed when new messages arive that match the
          alert_filter
        added the 'term' command which takes the 'raise' and 'deiconify'
          options.  It assumes xterm for now.
        only 'make distclean' will nuke core and ~ files now
        fixes to owl_function_do_newmsgproc from Stephen
        converted functions.c to new code style, which I'm giving a shot
        Makefile.in: define DATADIR, for default owlconf.
        Makefile.in: provide "all" and "install" rules.
        configure.in: try also libdes and libkrb4, for people using heimdal
        configure.in: see if des_ecb_encrypt is already prototyped.
        configure.in: minor changes to work with new autoconf without needing acconfig.h.
        configure.in: find the install program.
        configure.in: test for use_default_colors since some versions of
          solaris don't have it, so we can at least compile something
          vaguely working there.
        keypress.c: ifdefs for keys not defined on at least some solarises.
        owl.c: don't call use_default_colors if we don't have it
        readconfig.c: added *commented out* code to try to find a
          system-default owlconf if the user doesn't have one.  Have to
          ponder if I want this
        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
          des.h.
        zcrypt.c: include owl.h so we get the configure-generated config.h
        Change to codelist.pl to deal with new code style
        Remove some ancient stuff from zcrypt.c
        General cleanup to Makefile.in
        
1.2.8
        Class pings are displayed differently now
        Updated owlconf.simple example to format outgoing messages.
        
1.2.7
        Outgoing messages now go through the config for formatting
        Zaway now makes an outgoing message, instead of an admin message
        The 'zlocate' command can now handle multiple users
        The simple user format for "To:" is in effect again
        Prettyed up the zwrite line for using 'reply' on a zaway
        Added a workaround for a libzephyr bug that caused zwrites to fail
          if zephyrs were sent just before and just after renewing tickets
        Fixed a memory bug in getsubs
        Added receive support for zcrypt messages
        Added the 'zcrypt' variable which controls whether or not zcrypt
          messages are decrypted
        'reply' is disabled for zcrypt until sending zcrypt works
        Started implementing zcrypt command
        More updates to the intro doc
        
1.2.6
        Started adding code for newmsgproc.  It doesn't fully work yet!
          Don't use it.
        Added search, '/' and '?' to basic help.
        Will attempt to keep the current message as close as possible
             to the previous current message after an expunge.
        "set <variable>" and "unset <variable>" now work for boolean variables.
        Fixed a bug in owl_function_calculate_topmsg_normal that caused a
          segfault
        Fixed some typos in the intro doc
        Removed old zlog functions from zephyr.c
        Implemented the dump command
        New startup message
        
1.2.5
        Patch to fix memory bug in replying to CC messages
        If we're on Athena and have static krb (or other) libraries, use
          them
        Added "athstatic" program to the release, which handles the above
        Cast to an int for isspace, to make gcc -Wall quiet
        Added 'zlist' and 'l' to basic help.
        
1.2.4
        'zlog in' will now take an optional thrid argument to set the
             'tty' variable before setting the zlocation
        There is now a 'zlist' command that acts like 'znol -l'
        'l' is bound to 'zlist'
        Fixed memory leak uninitialzed memory read in fmtext
        viewwin will now say "End" instead of "More" when at the end
        Added a debugging message indicating the result of topmsg
          calculations
        You can now use %me% in filters
        The built-in personal filter is updated to do so
        Fixed a bug in moving the pointer after an expunge
        Fixed up the normal scrolling code.  Now it should always
          land on a message, but it's still not optimal.
        Added the variable 'smartstrip' which will strip kerberos
          instances out for the 'reply' command.
        Added -R/usr/athena/lib to the build for Athena
        Started updating the intro document
        Small changes to help / about
        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
          update .zephyr.subs by default.  If either is given the '-t'
          (for "temporary") option the .zephyr.subs will not be updated
        Turned off beeping for hitting the top or bottom of the list of
          messages
        Made daemon.webzephyr a special case for smartstrip
        Added 'out' as a default filter for outgoing messages
        
1.2.3
        Added filters "ping", "auto" and "login" by default.
        Added "body" as a valid field to match on in a filter.
        Temporary fix to bug where C-SPACE would cause the key handler to
             lock up.
        Messages now have a direciton (in, out or none).  Filters can
             match on this direction
        Outbound messages are no longer type 'admin' but are of the
             appropriate message type (i.e. 'zephyr') and are direction
             'out'.
        Smartnarrow now works on outgoing messages
        'info' updated to show more information for admin and outgoing
             messages
        Renamed pretty_sender to short_zuser and renamed long_sender to
             long_zuser
        Moved zsig generation to the zwrite object
        Print the zsig used for outgoing messages
        The tty variable now controls the zephyr location tty name
        
1.2.2
        Added the 'search' command.
        '/' is a keybinding for 'search'
        '?' is a keybinding for 'search -r'
        Fixed stristr, which was completely broken
        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
             and put it in functions.c
        Attempts to stay near the current message when switching views.
             When switching from an empty view to one we've previously
             been in, the new current message position will attempt
             to be close to the current position from the last 
             time we visited that view.
        Fixed bug in readconfig.c that prevented building under perl 5.005.
        Switched "C-x C-x" to only "startcommand quit"
        'getsubs' prints closer to the order you sub in.
        Modified the behavior of last so that "> >" will clear the screen.
        The new behavior of last is:
              Moves the pointer to the last message in the view.
              If we are already at the last message in the view,
              blanks the screen and moves just past the end of the view
              so that new messages will appear starting at the top
              of the screen.
        Fixed a typo in the help for smartzpunt.
        Fixed functions to handle curmsg being past the end of the view.

1.2.1
        New framework for command handling.
        New framework for keymap handling.
        Added commands for everything that is bound 
             to a key (do 'show commands' to get the full list).
        Added 'multi' and '(' commands to allow multiple commands
             to be specified on a line.              
        Added user keybindings with bindkey command.
        Added command aliases (eg, "alias foo bar").
        Added undelete command that parallels the delete command.
        Added additional options to delete command.
        The reply command now takes arguments.
        Added 'edit:insert-text' command.
        Added 'show zpunts' to show active punt filters.
        Added 'show variable <name>' and 'show variables'.
        Added 'show command <name>' and 'show commands'.
        Added 'show keymap <name>' and 'show keymaps'.
        Added 'M-u' to undelete all messages in current view.
        Fixed dotsend so that the zephyr will still send if there
             is whitespace after the dot but not on the same line.
             This should resolve an issue where dotsend wouldn't work
             if you'd gone up and edited a zephyr.
        Bug in page down fixed
        C-t will transpose characters
        Fix the scrolling bug where we would sometimes fail to scroll
             the screen down, leaving the current message off 
             the bottom of the screen.
        Refixed 'login or login' typo in help
        Fixed M-u description
        Removed 'first' and 'last' from basic command help
        Added M-N to basic key help
        Added M-D, M-u to basic key help
        Fixed a quoting problem in configure.in
        Changed top of help to use 'show' instead of M-x
        Fixed a bug in the summary field for user-created aliases
        Added "reply zaway" which sends a zaway response to the current msg.
        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
        Some buffer overruns fixed
        Variables now have a summary and a long description.
                Only the summary is shown with help.
                The long description is shown with "show variable foo".
        Added a 'scrollmode' variable which determines how the screen
             will scroll as the cursor moves.  The default behaves
             identically to previous versions of owl.
             The following modes are supported:
             normal      - This is the owl default.  Scrolling happens
                           when it needs to, and an attempt is made to
                           keep the current message roughly near
                           the middle of the screen.  (default)
             top         - The current message will always be the
                           the top message displayed.
             neartop     - The current message will be one down
                           from the top message displayed,
                           where possible.
             center      - An attempt is made to keep the current
                           message near the center of the screen.
             paged       - The top message displayed only changes
                           when user moves the cursor to the top
                           or bottom of the screen.  When it moves,
                           the screen will be paged up or down and
                           the cursor will be near the top or
                           the bottom.
             pagedcenter - The top message displayed only changes
                           when user moves the cursor to the top
                           or bottom of the screen.  When it moves,
                           the screen will be paged up or down and
                           the cursor will be near the center.
        Added owl_sprintf which returns the formatted string, or NULL.
                The caller must free this string.
                This will allocate enough memory and thus 
                avoid potential some buffer overrun situations.
        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
                message as having been sent.)
        The "Not logged in or subscribing to messages" error 
                now includes the name of the recipient.
        The "disable-ctrl-d" variable may also be set to "middle"
                which will result in ctrl-d only sending at the 
                end of the message.  This is now the default.
                This also added a command "editmulti:done-or-delete".
        Fixed a bug in the "reply -e" command.
        Always clear the command buffer before executing the command.
                (So that interactive commands can sanely do start-command.)
        Fixed preservation of e->dotsend across owl_editwin_clear().
        Added history for multiline edit windows (eg, for zephyr composition).
                The M-n and M-p keys will cycle through the history ring.
                In particular, it is now possible to edit the command line
                of a zephyr being composed:  C-c it and restart it 
                and then M-p to get the aborted composition back.
        Added owl::send_zwrite(command, message) to the perl glue
                to allow for the direct sending of multi-line messages.
                For example:  owl::send_zwrite("-c foo -i bar", "hello"); 
        Changed owl_fmtext_print_plain to return an alloc'd string to 
                avoid buffer overrun risks.
        Added owl::ztext_stylestrip("...") function to perlglue 
                 which returns the ztext with formatting stripped out.
        Added colorztext variable which can be used to disable @color()
                 strings arriving in messages after it is set.
                 (Currently, changing its value won't reformat messages).
        Outgoing zephyr logging now obeys the logpath variable.
        The '~' character in logpath and classlogpath now gets
                 replaced with the user's home directory.
        Added simple implementation of smartnarrow-to-admin that
                 creates a "type-admin" autofilter.
                 This was done mostly so that M-C-n and M-C-p do something
                 sane on admin messages.
        Added opera to the allowed options to the webbrowser variable.
        Fixed some buffer overruns in the "reply" command.
        When repying to "all" on a message that begins with "CC:" (eg, sent 
                 with "zwrite -C", the reply line will be constructed
                 from the sender and the usernames on the CC: line
                 of the message being replied to.
        There is no such thing as C-R, so left C-r as it is but added:
                 M-r --- edit reply to all
                 M-R --- edit reply to sender
        Added RCS Id strings to all files.
        'show keymaps' shows details of all keymaps after summary list.
        Added --no-move option to delete command.
                In particular, delete-and-always-move-down may now
                be implemented with 
                '( delete --no-move ; next --skip-deleted )'.
        Folded the nextmsg and prevmsg commands and functions together into 
                one command which takes arguments.
                Added '--filter <name>' option (eg, for next_personal),
                '--skip-deleted' option, and
                '--last-if-none'/'--first-if-none' options.
                Help updated accordingly.  
                In particular, the 'personal' filter is now used 
                for 'next personal'.  
                Added --smart-filter and --smart-filter-instance options 
                to the next and prev commands.
        Updated examples/owlconf.erik with the above.
        Made owl_function_fast*filt return a string and not do the 
                narrowing, to make it more general.
        Added a smartfilter command that creates a filter
                based on the current message and returns the name
                of the filter.
        Added M-C-n and M-C-p keybindings to "move to next message 
                matching current" and "move to previous message 
                matching current"
        Added variables edit:maxfillcols and edit:maxwrapcols which 
                will limit how wide editing paragraphs may get before
                they get wrapped.  This is a max and may be narrower
                depending on the current size of the window.
                If 0, the max is unlimited.  Default is 70 columns for
                edit:maxfillcols and unlimited for edit:maxwrapcols.
        Added smartzpunt command with key binding of "C-x k".
                This starts a zpunt command filled in with 
                the proposed zpunt.
        Fixed a memory reference bug in delete and undelete commands.
        Added support for perl to call directly back into owl.
        Changed the implementation of owl::command("...") to immediately
                call back into owl.  This allows perl to get the return
                value of strings returned by owl commands.
        Added the getview command which returns the name of the current 
                view's filter.  
        Added the getvar command which returns the value of a variable.
        Added an example to examples/owlconf.erik which uses TAB to 
                narrow and restore the view.  
        Added an example to examples/owlconf.erik which uses M-c to 
                color messages matching the current one green.
        Integrated change to fix problem with popup blinking on new zephyrs.
        C-l and resizes will now refresh an open viewwin (eg, help).
        Updated doc/code.txt to include info about filters, commands,
                contexts, and keybindings.
        Exec commands cleaned up to not have buffer-size limitations
                and to not mess up spaces.  exec also returns a string
                of the output now.
        Integrated changes from 1.1.3, and added docs for "zlocate -d"
                and new show commands.
        Show with arguments produces help on show.
        Fix a bug in readconfig caught by efence (where we'd try to read before 
                the beginning of a string if it was empty).
        The perl command doesn't do makemsg directly, but instead
             returns the string and it will get printed if it 
             was run interactively.
        
1.1.3
        'show subs' and 'show subscriptions' are now the same as 'getsubs'
        zlocate now takes an optional -d argument
        'show terminal' / 'show term'
        '>' / last doesn't set the last message at the top of the screen now
        implemented _followlast as an unsupported feature
        include 'default' in the 'show colors' list
        added help for 'zpunt' and 'zunpunt'

              a string not ending in a newline
        Added 'X' keybinding which expunges and then switches to 
              a view defined by the variable "view_home" which defaults

        Added dict.c which contains string->ptr dictionary routines
              and the owl_dict type.
              These include regression tests.
        Overhaul/rewrite of variable handling.  Variables are now managed
              in an owl_vardict (in g.vars) which contains a dictionary
              of owl_variable's.  Each owl_variable has dispatch functions
              for validating values, setting it and getting it,
              and for setting it to and from string values.
              The variable.c file contains the list of variables.
              Stubs for the owl_global_<varname>_get functions and friends
              are generated from variable.c by stubgen.pl.
              The help.c messages for variables now calls into variable.c
              so all information about most variables is in one place.   
        Cleaned out code from global.c and command.c that was made obselete
              by variable overhaul.
        The set command now takes a -q option to not log a message.
        Fixed a bug where set and print with no arguments would
              print "Undefined variable" in addition 
              to running owl_function_printallvars.
        debug is now a variable that can be turned on and off.
        Fixed mail,inbox message parsing in examples/owlconf.erik
        Made zaway_msg and zaway_msg_default into variables 
        Changed owl_function_makemsg and owl_function_debugmsg 
               to use varargs (ie, so they can now take a format
               string with args).
        Don't allow " and \ characters in URLs with the "w" command.
        Removed lots of build warnings.
        Popwins are wider by default so help messages fit better.
        Added an atokenize_free function.

        Added pageup and pagedown to viewwin

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