[keycloak-user] IBM DB2 not supported anymore?

Hi, in issue https://issues.jboss.org/browse/KEYCLOAK-7519 Stian added a comment saying   "Rejecting this as we removed support for DB2 in 4.x. DB2 had very few users    and was by far the most time consuming to maintain." Is it true that DB2 will not be supported anymore? Where has it been announced? I cannot find anything in documentation, release notes or blogs or user list mentioning it. I think you shouldn't drop support for DB2. It is a major enterprise database and many companies are using it. Cheers,     Manfred
