| Upgrade Guides for Genero BDL / 1.3x upgrade guide | |
When migrating to a 1.3x runtime system, you need to upgrade all front-end clients to any 1.3x version. Front-end clients and runtime systems are compatible if the major version number and the first minor number are the same (X.Y?). A front-end of version 1.31 works with a 1.30 runtime system, but combining for example a 1.20 client with a 1.30 runtime system is not supported.
