- In the createwallet, loadwallet, unloadwallet, and restorewallet RPCs, the
"warning" string field is deprecated in favor of a "warnings" field that
returns a JSON array of strings to better handle multiple warning messages and
for consistency with other wallet RPCs. The "warning" field will be fully
removed from these RPCs in v26. It can be temporarily re-enabled during the
deprecation period by launching bitcoind with the configuration option
-deprecatedrpc=walletwarningfield. (#27279)
