2004-07-20 0.7.6
Fixed:
- rdbms backend full text search failure after import (sf bug 980314)
- rdbms backends not filtering correctly on link=None
- fix anydbm journal import (sf bug 983166)
- handle postgresql bug in SQL generation (sf bug 984591)
- fix dates-from-Dates (sf bug 984604)
- fix messageid generated when msgid is None for send_message (sf bug 987933)
- make user permissions check more sane (fix search page for anonymous)
- fixed RDBMS filter() for no matches from full-text search (sf bug 990778)
- fixed DateHTMLProperty for invalid date entry (sf bug 986538)
- fixed external password source example (sf bug 986601)
- document the STATIC_FILES config var
- implement the HTTP HEAD command (sf bug 992544)
- fix journal export of files to remove content from CSV files
- API clarification. Previously, the anydbm/bsddb/metakit filter() methods
  had required exact matches to Multilink argument lists. The RDBMS
  backends treated Multilink matches like all other data types - matching
  any of the Multilink argument list is good enough. The latter behaviour
  is implemented across the board now.
- fix metakit handling of filter on Link==None
