-# Bitcoin ABC 0.26.0 Release Notes
+# Bitcoin ABC 0.26.1 Release Notes
 
-Bitcoin ABC version 0.26.0 is now available from:
+Bitcoin ABC version 0.26.1 is now available from:
 
-  <https://download.bitcoinabc.org/0.26.0/>
+  <https://download.bitcoinabc.org/0.26.1/>
 
-This release includes the following features and fixes:
-- In previous releases, the meaning of the command line option
-  `-persistmempool` (without a value provided) incorrectly disabled mempool
-  persistence.  `-persistmempool` is now treated like other boolean options to
-  mean `-persistmempool=1`. Passing `-persistmempool=0`, `-persistmempool=1`
-  and `-nopersistmempool` is unaffected.
-- This release supports Avalanche Post-consensus. See `bitcoind -help` for the
-  related options.
+This is a maintenance release with no user-visible change.
