Fund loss after upgrade to 0.5.0

[testz]

I upgraded to dev 0.5.0 and found the loss of 10 millions DVS from my accounts.
Even stranger, four delegates of mine, which were registered in the dev 0.4.28 and ranked in the top of list, disappear in the delegates list of the client of dev 0.5.0.

Is there a new blockchain used in the 0.5.0 instead of the old one existed in 0.4.28?

Yes, blockchain was reloaded because of allocation: http://bytemaster.bitshares.org/update/2015/01/08/DevShares-Reloaded
