 NOTE: The test is designed to prevent cases when compatibility is broken accidentally.
 In case we need to break mempool compatibility we can continue to use the test by just bumping the version number.
 
-The previous release v0.19.1 is required by this test, see test/README.md.
+Previous releases are required by this test, see test/README.md.
