  - Added support for category icons.  No Admin UI yet.  Icons should
    be in icons subdirectory named by the category id, such as

  - Added patch 1076313: Added support for HTMLAREA (see www.htmlarea.com)
    HTMLAREA is a WYSIWYG editor for HTML.
    This can be enabled in the Full Description by enabling
    HTML for full descrpitions in system settings and then installing
    the HTMLAREA files on the server.  There should be a file
    called .../includes/htmlarea/htmlarea.php when you have unzipped
    the files.

    When someone tries to access WebCalendar for the first time and this
    file is not found, the user is redirected to a new dbinstall page

  - Added check for webcalendar db tables right after initial db connection.
    Give user an error if tables not found.

    "incorrect password".  This should help sysadmins trying to setup
    WebCalendar figure out why a login is not working.
    Admins will need to enable $showLoginFailureReason in login.php to
    turn this feature on.  For security reason, the default will be
    to always say "Invalid login."

  - Fixed bug: Application name being set in System Settings was not
    being used in notification and reminder emails.

Version 0.9.37 (24 Jun 2002)
  - Added support for overriding or deleting single events in a
    repeating event.  New links at the bottom of the view event page
    allow you to delete repeating event for just one day, delete
    for all days, edit for just one day, edit for all days.  After
    adding an exception event, if the original repeating event is deleted,
    the exception event will also be deleted.
  - When deleting an event, just set the status in webcal_entry_user to
    'D' rather than deleting all the information from the database.
    So, users will still be able to view deleted events.
  - When viewing an event, display the status (right under description)
    if the status is anything but approved.  (So, it will show up if
    either Waiting on approval, Rejected, or Deleted.)
  - Converted README to README.html.
  - When viewing a repeating event, show the date the user selected
    to view (instead of the first date of the event) along with the
    repeating info.
  - Display view name under the date at the top of the page.
  - Fixed send_reminders.php to not send a reminder to users who
    rejected the event.
  - Modified webcal_entry_log activity log table by adding new cal_user_cal
    column.  One column for user performing action, another column
    (cal_user_cal) for who's calendar it affects.
  - Updated edit event handler to make sure user has proper authority
    to update an event.  (Prevent users from typing in a URL to make
    changes to an event.)
  - Added Activity Log page (accessible only by administrators) that
    shows recent activity for all events.
  - Updated French translation
  - Updated German translation
Version 0.9.36 (20 Jun 2002)
  - Fixed SQL bug in del_entry.php.
  - Added create table SQL in tables-postgres.sql and tables-oracle.sql
    for webcal_config table.
  - Added user-nis.php for NIS-based authentication
  - Reorganized the English-US.txt translation file.  All text is grouped
    by the page that it appears on.  Added new perl script in the tools
    directory called pagify_translation.pl that will take an existing
    translation and reorganize it in this way.  Hopefully, this will make
    translations a little easier since you can now determine the context
    of the text.
  - Improved session security by including a portion of the user's
    encrypted password in the cookie.
  - Fixed Bug 568261: Fixed send_reminders.php script which had been set to
    test-mode and was not sending mail.
  - Fixed Bug 568261: $LOG_REJECT was mispelled in includes/functions.php and
    was not allowing reminders to be logged in the activity log.
  - Fixed Bug 569135: URL for event was incorrect in send_reminders.php.
  - Patch 571298: LDAP speed improvements
  - Patch 571287: When selecting another user's calendar, display users
    in a pulldown rather than listing them all in a list.
  - Updated installation instructions and changed from plain text to HTML
    INSTALL.html.
  - Fixed bug: could not delete a layer if you have layers disabled.
  - Added mailto links on view event page and "Email all participants"
    link at the bottom.
  - Added event description, date and time to emails sent on
    event rejecting and event add/update.  Fixed reject_entry.php to use
    server URL set in admin system settings.
  - Send no-cache header for certain pages (week.php, month.php,
    day.php, layers.php, list_unapproved.php)
  - Converted UPGRADING notes to html UPGRADING.html.
  - Updated FAQ.html to include note about register_globals.
  - Replaced COPYING with GPL.html.
  - Updated German translation.
Version 0.9.35 (05 Jun 2002)
  - Added fancy new admin interface for setting WebCalendar settings. 
    Almost all settings previously found in config.inc are now set
    through the new admin interface.
  - Allow user to customize application title (appears in page titlebar
    and login page).
  - Added event URL to email notifications.
  - Added ability to specify main URL for WebCalendar (included in
    email reminders and notifications) from within the new admin interface.
    Default value for server location will be calculated but can be
    modified.
  - Removed "Browser-defined" as a language option for users in the
    preference settings page.  Users must select a language.
    Additionally, if the user has not made a language setting and one
    can be determined from their browser settings, then the language
    setting will be saved in the database (so that it can be used when
    sending email reminders).
  - Added ability to customize the default text color (for users that
    prefer to set their background to black).
  - Added support for user views (month and week) that allow users
    to create a custom view of specific users and view their calendars
    side by side.  Views are unique to each user so that if user A
    creates a view, then user B will not be able to see the view.
  - Added support for mouse-over tooltips using style sheets.  Unfortunately,
    only MSIE supports this, but it's a cool feature.  Currently supported
    on the admin settings, preferences, and add/edit event pages.
  - Added the long-asked-for group support.  Users can belong to more than
    one group (or none).  The calendar can be configured to allow users
    to access all groups and users or it can be setup so that (non-admin)
    users only see groups that they are members of and users that are in
    those groups (see config.php).
  - Added support for public access to the calendar that requires no
    login.  Works with web-based login and HTTP-based login.  However,
    HTTP-based authentication setup is more complicated (see FAQ).
  - Renamed all include files from .inc to .php.  This will help avoid
    security holes if users don't turn off browsing in the includes
    directory.
  - Improved security of edit_user_handler.php to prevent knowledgeable
    users from typing in a URL to make user updates that cannot be made
    from the web interface.
  - Display URL of event when sending out an email notification.  (Not
    yet implemented for reminders.)
  - Patch 548138: Added Interbase support
  - Fixed incorrectly displayed status of layers in main layers page
    (layers.php).
  - Fixed missing password on PostgreSQL login in php-dbi.php.
  - Some URLs in description were not being linked properly.
  - Fixed fonts in week view to be consistent size.
  - Layers now display in new color (defined in styles.php) and are
    no longer underlined.
  - If $allow_color_customization was set to false in config.php, users
    were getting an error on saving preferences.
  - Check user preferences for receiving reminders before sending one.
  - Updated send_reminders.php to be LDAP-aware.  Now uses same user
    functions as rest of the system.
  - Updated send_reminders.php to check language preference for each user.
    If user has set a language preference, reminders will come in that
    language.  (Language will be auto-set in the system the first time
    they access the calendar with a browser.)
  - Modified printer-friendly pages to use a single table with a visible
    border for better printing.
  - Enhanced search page to allow searching of other user's calendars
    if allowed by system settings.
  - Fixed bug 530015: allow duration hours and minutes to be more than
    two characters long.
  - Don't allow a user to create a layer using their login as the source.
  - Feature request 529453: show user's fullname rather than login in
    the popup for an event of another user showing up in a layer.
  - Modified all calls to mktime() to use 2AM instead of midnight in
    hopes of squashing all daylight-savings-related bugs.
  - Fixed bug 449084: Don't allow users to enter a time of 24:00 for an
    event (when using 24-hour time format).
  - Fixed bug 491615: Preserve new lines in description when displaying
    in event popup.
  - Added activity log for events that is available to administrators.
    Tracks event creation, update, accept, reject, notification and
    reminders.
  - Updated FAQ and converted it to HTML.
Version 0.9.34 (16 Dec 2001)
  - Patch 468897: Fix default for new calendar entries to be public (not
    confidential)
  - Patch 469755: Do not allow users to change preferences in a read-only
    setup
  - Fixed bug: layers would not work until a user turns them off and then
    back on.
  - Display users in a table on page to select other user's calendar for
    better display (if more than 20 users).
  - Patch 483782: Delete users even if they have events and delete those
    events.
  - MS IIS/PSW workaround: IIS does not allow you to send a cookie and
    a redirect in the same http header, so all redirects are handled
    using html meta tags when IIS is detected.
    Code submitted by Nick Temple <ntemple@teentriumph.org>.
  - Fixed bug 447339: In week view, events would not span enough hours
    in the display if there was another event later in that day.  In
    day view, all events would display in a one hour block even if they
    were longer than an hour.
  - Added Galician translation.
  - Added Hungarian translation.
  - Updated Swedish translation.
  - Updated French translation.
Version 0.9.33 (02 Aug 01)
  - Fixed bug: the "back to my calendar" link would go to another user's
    calendar if you just viewed another user's calendar.
  - Fixed bug: was not displaying more than one event per day in the
    week view.
  - Removed all the <?php_track_vars?> from every .php file since it was
    causing problems for a lot of people.
  - Fixed bug: User who logged in to the 0.9.31 version would have a
    session cookie that would generate a "Error getting user" message.
    Now redirects them back to the login page.
  - Fixed bug: don't display access, priority and participants in email
    reminders if they've been disabled in config.inc
  - Added missing user-ldap.inc to the distribution.
  - Updated Swedish translation
Version 0.9.32 (26 July 01)
  - Fixed some of the login/session code.  After examining the code, I'm
    surprised it worked at all! :-)  And, it suddenly stopped working on
    my system (would not allow any logins), so it could very will have
    been the bug that prevented people from being able to login.
  - Fixed bug: Was not allowing admin users to add events to a read-only
    setup.
  - Attempted to not reference undefined variables to avoid the warnings
    generated by PHP when the warning level is set to complain about
    referencing undefined variables.
  - Fixed bug: Was not allowing selection of a user when adding/editing
    layers.
  - Fixed bug: If you set a reminder to be sent at the exact time
    of the event (0 days, hours, minutes before event), then when
    you come back to edit the event, it shows the default time before
    rather than 0.
  - Fixed bug: printer friendly version of week view was displaying
    events as links.
  - Fixed use of php_track_vars.  Was using <?php php_track_vars?>.
    Proper use is just <?php_track_vars?>.
  - Fixed bug 441688: MySQL does case-insensitive searches, which allows
    a user named 'cknudsen' to login with 'CKnudsen', which causes
    problems.  Now, users can only login with correct case-sensitive
    login.
  - Fixed bug: when view a non-repeating event, some of the
    text for repeating events ("every") would be displayed next
    to the event date.
  - Remember the last view (week, day or month) and return to it
    instead of returning to the preferred view.  For example, if
    you were viewing March 2002, then viewed an event in that
    month, and then deleted it, you would be returned to the
    March 2002 view after the delete. (Uses cookies to do this.)
  - Fixes to php-dbi.inc for postgres and odbc issues.  May break
    compatibility with early versions of PHP 3.0 and PHP 4.0
  - Updated INSTALL and FAQ files.
  - Initial LDAP support.
  - Security improvement: Use $single_user boolean rather than using
    strlen ( $single_user_login )
  - Fixed bug 438980: Oracle SQL syntax error in tables-oracle.sql
  - Fixed bug: When participant list display is disabled, events
    were not being created properly.
Version 0.9.31 (02 Jul 01)
  - Added Swedish translation.
  - Updated Dutch translation.
  - Added ability to disable some of the standard event fields (access,
    priority, participants, repeating) to simplify interface for some
    users.  Set in includes/config.inc with $disable_priority_field,
    $disable_access_field, $disable_participants_field, and
    $disable_repeating_field.
  - Can now specify $allow_view_other to be false in includes/config.inc
    to prevent users from viewing other users' calendars.  (Admin users
    will still be able to do this.)  The combination of this and setting
    $disable_participants_field = true will give non-admin users the
    feel of a single-user calendar.  (Note: Setting $allow_view_other
    to false will also disable layers since that is essentially viewing
    another user's calendar.)
  - Added $conflict_repeat_months to includes/config.inc.  This defines
    how many months into the future we should check for conflicts when
    saving a repeating event.  On a slow server, the default (6 months)
    may take too long.
  - Fixed bug 436330: Oracle complaining about too many open cursors.
    Added some missing dbi_free_result() calls to address this.
  - Fixed bug 436404: Error in conflict checking - was always replacing
    first event participant with event creator when checking for
    conflicts.
  - Feature request 423034: On the event view page, any URLs found
    in the description field will be turned into an HTML link for
    you.  Don't enter HTML in the description, just enter the URL
    somewhere in the description.
  - Feature request 432334: Display week number in week view.
  - Updated French translation to use HTML escapes for non-standard
    characters.
  - Patch 435431 from Franz Sedlmaier:
    Display repeating event information on event view page.
  - Patch 435403 from Franz Sedlmaier:
    When a user edits an event, save the existing status (accepted,
    rejected) of each user rather than resetting it back to
    pending.  Don't send users notifications unless the date/time changed.
  - Patch 435396 from Franz Sedlmaier for bug 435390:
    Notification for rejecting events was not working.  Don't send
    the notification to other users who rejected the event.

  - Changed styles.css to be a PHP include (styles.inc) so some of it
    can be generated dynamically (eventually)
