MDB has a bug inhibiting downloading of files larger than a certain size.  Output buffering was accidentally left on during file download, so files larger than the output buffer (usually 128M) are truncated to that size.  The one little fix is a bit too small for a whole release right now, so I’ll either have to wait to do more fixes or until a little time has passed and I feel that no other fixes will be coming.  Either way, the fix is in gitphp so if it’s a problem you can grab the snapshot.

Codex is currently getting the same massive revamp, feature boost, and cache framework that MDB got.  It’s my oldest full fledged PHP/SQL project so it has the crappiest code and could benefit the most from such a thing.
