More than once per week I receive an email or message or comment or call or instant message by a colleague or customer or partner seeking for any news about the release of Oracle Database 18.104.22.168 as Standard Edition.
Ok, sit back, relax - it's still not available.
But there are significant and important news outlined in
Oracle Database 12c Standard Edition 2 (22.214.171.124).
