Release notes 0.19.3

Bitcoin ABC version 0.19.3 is now available from:

This release includes the following features and fixes: - Added optional blockhash parameter to getrawtransaction to narrowly search for a transaction within a given block. New returned field in_active_chain will indicate if that block is part of the active chain. - signrawtransaction RPC is now deprecated. The new RPCs signrawtransactionwithkey and signrawtransactionwithwallet should be used instead. Use -deprecatedrpc=signrawtransaction to temporarily re-enable the old behavior while you migrate.
