-### Summary
 
-- Zebra now drops transactions with unpaid actions in block templates and from
-  the mempool.
+- Zebra now uses a default unpaid actions limit of 0, dropping transactions with any unpaid actions from the mempool and excluding them when selecting transactions from the mempool during block template construction.
 - The `zebrad` binary no longer contains the scanner of shielded transactions.
   This means `zebrad` no longer contains users' viewing keys.
 - Support for custom Testnets and Regtest is greatly enhanced.
