[Ovmsdev] Firmware release 3.3.004

Mark & everyone, there are new feature extensions in the pull request queue, i.e. poller timing control by Michael Geddes & a new MG5 model variant by Peter Grey. I'd rather close 3.3.003 now and release the current state as main 3.3.004 before merging new features that again would need testing. A new main release is overdue, and the latest fixes by Michael Geddes did improve stability significantly. I haven't had a single crash with 3.3.003-621 yet. Objections? Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26
