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

The 'changelog' is a log (or list) of all the changes made to the
Personal Open Directory.

This list is in reverse order so the most recent changes are at the
top:

v1.73d 31-Mar-2000 RC
 - Fixed World/ bug
   The script was un-escaping all topbit characters - unfortently
   it was re-escaping them for the URLs. This section was just disabled -
   I bet it's affected something else, but I can't see what.
 - Fixed Search guide
   The routine that checks if the page was a search or not was being
   mis-read when it found the search guide. Now added a bit more
   information for it to compare
 - Fixed advanced searches
   POD now compiles all the search parameters into a single variable
   ($pod_build_searchparams) which is added onto the end of the DMoz
   search URL. Should fix this problem.
v1.72d 11-Mar-2000 RC
 - New configuration variables:
   $pod_headersuppress
    Disables full HTTP headers - only returns Content_Type
 - Fixed error in documentation 'Appendix' regarding the chmod command
   and the octal settings (thanks to donlaur at midwest.net for reporting)
 - Added FAQ entry 056 'Software error: podvars.pm did not return a true
   value at pod.cgi'
 - Should have fixed a slight bug in the 'search parser' when it
   was looking for the string 'osearch', it now looks for '/osearch'
   which should make all the difference.

v1.71d 29-Feb-2000 RC
 pod.cgi should now handle RDF files correctly (ie redirecting the
  browser).
 Bug regarding certain types of fetches fixed.
  
v1.70d 28-Feb-2000 RC
 Major re-write of most of POD. Not compatible with previous
 versions. Major changes include:
  - Now returns the Content-Length: and Expires: headers.
  - Formatting should now be fixed on all pages (including FAQs and
    'Add a page')
  - Problem with all searches (and the searchguide.html page) fixed
  - Better blocking against Denial of Service (D.O.S) attacks
    implemented
  - Mozzies and 'cool symbols' are customisable and removable
  - All variables and routines are now prefixed by pod_ - most handy
    if you use the POD code in your own program
  - Descriptions and FAQs in 'fake pages' (such as Regional/UK) now
    work
  - Add a site, Become an editor, Update URL and Password Reminder
    functions now work
  - Header and Footer are now defined in podvars.pm
  - Proxy support added (untested though)
  - No longer requires fnctl or URI::Escape libraries
