 # Bitcoin ABC 0.25.8 Release Notes
 
 Bitcoin ABC version 0.25.8 is now available from:
 
   <https://download.bitcoinabc.org/0.25.8/>
 
 This release includes the following features and fixes:
 - Users can start their node with the option `-coinstatsindex` which syncs an
   index of coin statistics in the background. After the index is synced the user
   can use `gettxoutsetinfo` with hash_type=none or hash_type=muhash and will get
   the response instantly out of the index
 - Users can specify a height or block hash when calling `gettxoutsetinfo` to
   see coin statistics at a specific block height when they use the `-coinstatsindex`
   option.
+- Additional amount tracking information has been added to the output of
+  `gettxoutsetinfo` when the `-coinstatsindex` option is set.
