270 # Revision 1.13 2001/10/05 02:23:24 richard
271 # . roundup-admin create now prompts for property info if none is supplied
272 # on the command-line.
273 # . hyperdb Class getprops() method may now return only the mutable
274 # properties.
275 # . Login now uses cookies, which makes it a whole lot more flexible. We can
276 # now support anonymous user access (read-only, unless there's an
277 # "anonymous" user, in which case write access is permitted). Login
278 # handling has been moved into cgi_client.Client.main()
279 # . The "extended" schema is now the default in roundup init.
280 # . The schemas have had their page headings modified to cope with the new
281 # login handling. Existing installations should copy the interfaces.py
282 # file from the roundup lib directory to their instance home.
283 # . Incorrectly had a Bizar Software copyright on the cgitb.py module from
284 # Ping - has been removed.
285 # . Fixed a whole bunch of places in the CGI interface where we should have
286 # been returning Not Found instead of throwing an exception.
287 # . Fixed a deviation from the spec: trying to modify the 'id' property of
288 # an item now throws an exception.
