flag, as it's not as useful anymore and can cause problems if set
without planning. Invoice module added new invoice-date-format
template, rather than creating a bunch of optional date formats.
Also added invoice-date-offset to have more control over the
invoice subject. Remove Purchase->ActiveUsers as this is now done
by the Invoice module. Fixed an issue in the Purchase module where
purchasing with the same account on consecutive days would load the
previous day's purchases. Control module settings callback still
uses the word 'fixed' for position but applies the value 'sticky'.
Also assumes default is now opaque for control and applies
transparency class for absolute positioning only. Minimise button
has been removed because sticky positioning doesn't obscure the
top of the page. Old browser specific css properties have been
removed from write_style as support for generic properties is much
better. SimplePie->Item fix following recent changes, enclosure
caching needs to make sure the url is for an image. Microformats
url fetcher has a new default option to return json as Firefox has
a new json viewer enabled by default.
