Notable changes

Fixes

This release fixes an issue that could potentially cause a node to crash with the log message "The wallet's best block hash <hash> was not detected in restored chain state. Giving up; please restart with -rescan."

RPC Changes

• z_sendmany will no longer select transparent coinbase when "ANY_TADDR" is used as the fromaddress. It was already documented to do this, but the previous behavior didn’t match. When coinbase notes were selected in this case, they would (properly) require that the transaction didn’t have any change, but this could be confusing, as the documentation stated that these two conditions (using "ANY_TADDR" and disallowing change) wouldn’t coincide.

The following features have been deprecated, but remain available by default. These features may be disabled by setting -allowdeprecated=none. 18 weeks after this release, these features will be disabled by default and the following flags to -allowdeprecated will be required to permit their continued use:
