Bitcoin ABC version 0.21.11 is now available from:
https://download.bitcoinabc.org/0.21.11/
This release includes the following features and fixes:
generate RPC method was deprecated in v0.21.5 and has now
been fully removed. This RPC is only used for
testing, but its implementation reached across multiple subsystems
(wallet and mining), so it has been removed to simplify the
wallet-node interface. Projects that are using generate for testing
purposes should transition to using the generatetoaddress RPC, which
does not require or use the wallet component. Calling
generatetoaddress with an address returned by the getnewaddress
RPC gives the same functionality as the old generate RPC.
