We can't say we officially support PostgreSQL, unfortunately. There
are too many database calls with MySQL specific syntax. This would be
desirable for a 2.0 release, but too much work while maintaining 1.x.
The main difficulty is that we're using PEAR::DB which is aging. If
that's exchanged, maybe we could use PDO or something.

Also, tooltip text on time representation for humans has been improved.
Unfortunately no standardised representation (like "RFC850") had 4-digit years.
The File object now stores width and height of files that can
supply this kind of information. Formats which we can not read
natively in PHP do not currently benefit from this. However an
event hook will be introduced later.
The CreateFileImageThumbnail event is renamed to:
CreateFileImageThumbnailSource to clarify that the hooks should not
generate their own thumbnails but only the source image. Also it now
accepts File objects, not MediaFile objects.
The thumbnail generation is documented in the source code. For
developers, call 'getThumbnail' on a File object and hope for the best.
Default thumbnail sizes have increased to be more appealing.
Avoiding collisions with date (shorter than before) and 4 character
random alphanumeric string. I bet someone could mass-upload files
and generate all combinations of aaaa-zzzz during the course of a
day, but then maybe that user should be disabled anyway :)
(filling the collision space will cause a never-ending loop).
The exception thrown from MediaFile will be caught and simply result in
no thumbnail at all right now. In the future we might use a catch-all
and have a "cannot generate preview"-icon or something.
VideoThumbnails requires php5-ffmpeg and php5-gd.
spl_autoload_register now calls the GNUsocial_class_autoload function
instead of us replacing the magic __autoload($cls). This means we can
queue up other autoload functions, such as the one now used for extlib
functions which exist directly in the 'extlib/' folder or have proper
namespacing (which our new Markdown class does).
At the same time we remove the "filecommand" setting, since we will
likely not have use of it thanks to PECL fileinfo.
Also the "supported" list for attachment mime types has changed
format, so we can keep track of at least some known file extensions.
Because if you have your own local/closed community, likely you
don't want random newcomers that drop in, spam and leave dead
accounts.
The Admin can of course always override this by setting the config
"inviteonly" to false either in the config.php or on the website.
