If no new bugs are found, we will no longer maintain 0.x version of Holakit. 0.23.0 might be the last version of Holakit 0.x and 0.23.x is surely the last minor release of 0.x. If for some reason you won't adapt Holakit 2.x later, you can treat this version as the only stable version and once Holakit 2.x is out, this version won't be maintained anymore.
