Bitcoin ABC version 0.21.3 is now available from:
This release includes the following features and fixes:
- Fixed a bug where the `listtransactions` RPC was unable to list transactions
by a giving label. This functionality has been restored.
- MacOS versions earlier than 10.12 are no longer supported.
Additionally, Bitcoin ABC does not yet change appearance when macOS
"dark mode" is activated.
+ - Fixed missing help text in `getblockchaininfo` RPC.
New RPC methods
------------
- `listwalletdir` returns a list of wallets in the wallet directory which is
configured with `-walletdir` parameter.
Low-level RPC changes
----------------------
- `-usehd` was removed in version 0.19.7. From that version onwards, all new
wallets created are hierarchical deterministic wallets. Version 0.21.3 makes
specifying `-usehd` invalid config.
Thread names in logs
--------------------
- Log lines can be prefixed with the name of the thread that caused the log.
To enable this behavior, use `-logthreadnames=1`.
