This ensures that everything that descends from an invalid block is marked as such. Though blockmaxweight has been preferred for limiting the size of blocks returned by getblocktemplate since 0. Using this option resulted in a few UI issues as well as non-optimal fee selection and ever-so-slightly worse performance, and has thus now been deprecated.
Further, the blockmaxsize option is now used only to calculate an implied blockmaxweight, instead of limiting block size directly. Any miners who wish to limit their blocks by size, instead of by weight, will have to do so manually by removing transactions from their block template directly.

It is no longer possible to open copies of the same wallet.
A hidden debug argument -minimumchainwork has been added to allow a custom minimum work value to be used when validating a chain. This is a security measure as well as prevents dangerous user mistakes. The behaviour is unchanged when an empty string is provided.
