Mapdb.persist

In the past, I had no problems with mapdb.persist

Strategies {default = everyChange} Items {mCR* : strategy = everyChange, restoreOnStartup}

Now with Release 5.1.x, I get after starting

22:34:27.589\[WARN\] \[org.openhab.core.model.core.internal.ModelRepositoryImpl\] - DSL model ‘mapdb.persist’ has errors, therefore ignoring it: \[3,13\]: no viable alternative at input ‘default’

and due to the missing restoreOnStartup, various subsequent problems. Additionally, then occurs every minute

even if that doesn’t seem to have anything to do with persistence

please, where is the error

default has been depreciated. Don’t use it. Search the forum, there are plenty of posts and it is in the 5.1 release notes.
