-Wallet `generate` RPC method deprecated
----------------------------------------
-
-The wallet's `generate` RPC method has been deprecated and will be fully
-removed in v0.19.
-
-`generate` is only used for testing. The RPC call reaches across multiple
-subsystems (wallet and mining), so is deprecated to simplify the wallet-node
-interface. Projects that are using `generate` for testing purposes should
-transition to using the `generatetoaddress` call, which does not require or use
-the wallet component. Calling `generatetoaddress` with an address returned by
-`getnewaddress` gives the same functionality as the old `generate` method.
-
-To continue using `generate` in v0.18, restart bitcoind with the
-`-deprecatedrpc=generate` configuration.
