 # Bitcoin ABC 0.24.4 Release Notes
 
 Bitcoin ABC version 0.24.4 is now available from:
 
   <https://download.bitcoinabc.org/0.24.4/>
 
 This release includes the following features and fixes:
 
 - Bitcoin ABC will no longer create an unnamed `""` wallet by default when no wallet is
   specified on the command line or in the configuration files. For backwards compatibility,
   if an unnamed `""` wallet already exists and would have been loaded previously, then it
   will still be loaded. Users without an unnamed `""` wallet and without any other wallets
   to be loaded on startup  will be prompted to either choose a wallet to load, or to
   create a new wallet.
 - A new `send` RPC with similar syntax to `walletcreatefundedpsbt`, including
   support for coin selection and a custom fee rate. Using the new `send` method
   is encouraged: `sendmany` and `sendtoaddress` may be deprecated in a future release.
 - The `testmempoolaccept` RPC returns `size` and a `fee` object with the `base` fee
   if the transaction passes validation.
+- A "sequence" notifier is added to ZeroMQ notifications, enabling client-side mempool
+  tracking.
