Alright, status update: I got sidetracked so to speak. We had to do some cleanups in API as well so next one is 0.5.0. It's based of Lazarus 0.9.22 (because of some fixes in it) so I had to wait. I'm trying to apply some last minute patches I got regarding HTTP and release it.
Sadly the streaming didn't get in yet. The good news is that we fixed loads of little ugly bugs, like UDP failure with Listen/Connect combo, and some windows "blocks" problems with menus or dialogs in Lazarus.
So while it's a 0.4->0.5 transition the major change is because of some (not so bit) API change.
Added was WinCE support but it's beta since FPC itself doesn't support it in stable yet.
I got sidetracked this week by some school surprises but we SHOULD release it this week. The streaming stuff was not implemented because of lack of time and some conflicts regarding design decisions IIRC.
