This is a patch version for v2.0.0, which fixes the rare condition where it could cause a fork of the blockchain. This version supersedes the v2.0.0 and co-exists with legacy version of 1.8.1.
For v2.0.1 release, the DV version is v2.0.1.0-bfaefc188(DV) and non-DV version is v2.0.1.0-56c75511f. Both windows qt files are registered with deeponion blockchain and you can verify your download with DV using owner address Dg9D3ZvXoLk6Ysw5SG8VVMiMDqXmWvEbjt.
There is a difference between the DV and non-DV version, besides the existence of the DeepVault feature. For the non-DV version the blockchain check is disabled by default (you can enable it with the DeepOnion.conf file, use checkblockchain=1). With the DV version the blockchain check cannot be disabled, because DV info is scanned at the start of the wallet, so the blockchain is checked at the same time.
