Release notes 0.19.6

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.
