PO has released a new version. We're upgrading our server now at some point in the future.
1.0.53 should be stable, with all the various bugs associated with 1.0.52 fixed. So feel free to upgrade. However, it's still probably a good idea to back up your old version of PO, just in case.
If you're having issues with 1.0.53 and need to downgrade, you can download the old version here: http://pokemon-online.eu/forums/showthread.php?8711-1.0.30
DO NOT report any bugs related to 1.0.53 in this forum. Report those to Pokemon Online.
There have been reports of instability with the new client for mac users on Snow Leopard, so we are recommending that Snow Leopard users HOLD OFF on upgrading their clients. If you are not on Snow Leopard, it *should* be okay for you to upgrade, but there is no advantage to doing so, since our server is still on 1.0.30. Still, if you want to, go ahead. Just be sure to make a backup of your existing PO version.
