-# Bitcoin ABC 0.26.2 Release Notes
+# Bitcoin ABC 0.26.3 Release Notes
 
-Bitcoin ABC version 0.26.2 is now available from:
+Bitcoin ABC version 0.26.3 is now available from:
 
-  <https://download.bitcoinabc.org/0.26.2/>
+  <https://download.bitcoinabc.org/0.26.3/>
 
 This release includes the following features and fixes:
- - The deprecated `addnode` and `whitelisted` fields have been removed from the
-   `getpeerinfo` RPC output. Users relying on the `deprecatedrpc` behavior need
-   to update their system accordingly.
- - The `isfinaltransaction` RPC now returns a detailed error when the
-   transaction is not found, instead of simply returning false.
- - Some log messages have been moved to debug categories, to improve the
-   signal-to-noise ratio. Users relying on these log messages can enable them
-   with the `-debug=blockstore,validation` command-line argument.
