I am a moderator of
dolibarr.es forum and I knew that Dolibarr 3.5.1 was released from an user after telling him that he could not have tried 3.5.1 because it was not yet released, because
dolibarr.org tells the last stable version is 3.5.0 and there is not even any communication to developers or translators.
This is the 2nd time I complain about release notifications and it seems that there is no willing to change the situation...
