Bitcoin ABC version 0.21.9 is now available from:
This release includes the following features and fixes:
- Improve management of maxfee by the wallet.
Wallet changes
--------------
When creating a transaction with a fee above `-maxtxfee` (default 0.1 BCH),
the RPC commands `walletcreatefundedpsbt` and `fundrawtransaction` will now fail
instead of rounding down the fee. Beware that the `feeRate` argument is specified
in BCH per kilobyte, not satoshi per byte.
+
+RPC changes
+-----------
+The `getblockstats` RPC is faster for fee calculation by using BlockUndo data. Also, `-txindex` is no longer required and `getblockstats` works for all non-pruned blocks.
