Bitcoin ABC version 0.19.6 is now available from: This release includes the following features and fixes: - Using addresses in createmultisig is now deprectated. Use `-deprecatedrpc=createmultisig` to get the old behavior. - Added `savemempool` RPC command for dumping mempool to disk. - Added `-blocksdir` command line option for saving block data to a different disk location (such as a higher-capacity HDD). - Fixed a few related issues where quickly shutting down bitcoind after startup would result in a crash. - Multiple minor node stability improvements. - Fixed a small memory leak. - Removed `-nodebug` option, as `-debug=0` already exists as an equivalent. - Fixed a bug where `bitcoin-cli generate` would hang until completion when attempting to interrupt the process. It now shuts down cleanly as expected.
