This release fixes a critical oversight introduced in the 3.0.10 release which lead to an unintentional fork on block 1,232,433. This was possible because a node staked the exact same ATXO (SPECTRE output) with the same wallet.dat on different network nodes. Normally one chain would win and the other blocks would become orphaned. In this case because of the oversight, a minority of 3.0.10 and 3.0.11 wallets which received the later orphaned block before the block of the main chain, continued to stake the fork.
We informed the exchanges and to our knowledge they have always been on the main chain.
Please update your node to 3.0.12 as soon as possible. The wallet will check if you are on the main chain and if not abort with a corresponding message.
We are truly sorry for this inconvenience.
