============================================================================

01/15/99: Bug fix: permission to edit an item or response may sometimes
  get confused.
  Files changed:
  SP40/imanage.cml   Line 14, two-line "if $and ($not_equal(" construct
                     was missing "\" line continuation

01/13/99: Bug fix: in some cases, newly created conferences may not
  appear visible to the creator (w/o exiting and re-entering caucus).
  Files changed:
  SP40/man_createf.cml  (added "eval $cl_list()" line immediately after
                         test for cnum > 0)

01/13/99: Bug fix: several manager pages do not correctly test for proper
  management capability.  Typical symptom: a manager feature will appear
  not to have worked (when in fact it probably did work).
  Files changed:
  SP40/man_archive.cml
  SP40/man_cname.cml
  SP40/man_create.cml
  SP40/man_groups.cml
  SP40/man_list.cml
  SP40/man_org.cml
  SP40/man_popular.cml
  SP40/man_remove.cml
  SP40/man_switch.cml
    All these files have the same change: on or around line 12 is a line
    that looks something like:
         if $not($bit_and($word(2 $mgr_list($userid())) 8)
    It is missing a closing right parenthesis, i.e. it should read:
         if $not($bit_and($word(2 $mgr_list($userid())) 8))

11/02/98: Bug fix: creating multiple "groups" in a row from the management
  menu deletes the previous group(s).
  Files changed:
  SP40/man_groups.cml  add "set filename" after main if/else.
  SP40/man_groupsf.cml under "If the filename has changed, delete the old one"
                       expand $and() to include $not_empty($(filename)).

10/13/98: Bug fix: entering a conference or item from a bookmark, or
  after a swebs has "timed-out", can cause "NO CONF" errors, if and
  only if the conference in question is not in the "popular" or
  user's personal conference list.
  Files changed:
  SP40/startup.i  New code for "Pre-load the cached conference list" section.

08/28/98: Bug fix: entering through caucus.cml can cause multiple calls
  to $cl_list() with no args, which can be very slow.
  Files changed:
  SP40/caucus.cml    put a "return" after every "include... startup.i"

08/07/98: Bug fix: <FORM>s not allowed in a response (since an item was
  implemented as a single <FORM>).
  Files changed:
    SP40/clearchk.js, indvresp.cml, popup.js, viewitem.cml
     (Replaces document.scroll.elements[i] with document.forms[i].bx)

08/07/98: Bug fix: %conference(xyz) macro underlines all following text
  if XYZ does not exist or is not accessible.
  File changed: 
    SP40/Local/macros.i   change 2nd <U> in %conference to </U>.

07/29/98: Bug fix: if password confirmation is enabled, a blank password
  should produce a warning message.
  File changed: 
    SP40/passchkf.cml   1st "Location" line must end as "...+$arg(2)+x+x".

06/19/98: Bug fix: uploaded images may appear "broken" if followed by
  text.  Caused by typo in "libimg" macro definition.
  File changed: 
    SP40/Local/macros.i    (end of libimg line, change ')">' to '">)' )

06/17/98: Bug fix: "Pass" button sometimes shows wrong target, such as
  a previously visited item number, when it should show the conference
  home page, or the conference center.
  File changed: 
    SP40/viewitem.i

06/17/98: Bug work-around: "List" link at top right of item list is
  disabled, to prevent use of buggy $item_sort() function.
  File changed: 
    SP40/ilist.i  (comment out "Last" code and insert text "Last").

06/16/98: Extension: add page for reading a range of items.  E.g. in a
  conference home page Greeting, one can add CML text that says something like
  "To understand the use of this conference, please read the
  "<A HREF="$(href)/readrange.cml?$arg(3)+1+3">first three items</A>.
  File added:
     SP40/readrange.cml

  Files changed:
     SP40/members.cml  Add $cl_access() verification at top of file.

06/05/98: Bug fix: delete old "groups" file when renamed; create empty
  groups (no description, no members) properly.
  Files changed:
     SP40/man_groups.cml
     SP40/man_groupse.cml
     SP40/man_groupsf.cml

  Files changed:
     SP40/man_groups.cml

  between IE 3 and IE 4.
  Files changed:

     SP40/gotof.cml    Add window.opener.pop_gone('goto'); before window.close.

  userid/password record is not maintained by Caucus.  (This means the
  userid can be removed from Caucus, but the userid/password entry may
  still exist.)
  Files changed:
     SP40/man_users.cml
     SP40/man_usersf.cml

04/08/98: Bug workaround: $cleanhtml() returns its 1st arg if there is no
  2nd arg.  The workaround is to test for the non-emptiness of the 2nd
  arg before calling $cleanhtml().
  Files changed:
