Details

From now on, DDL before schema upgrade is allowed for schema versions >=
2.11.1 (previously it was forbidden in 3.0.0 release). In documentation
we need to create a list of features, which are forbidden until some
versions. Current state:

• DDL before box.schema.upgrade - forbidden until 2.11.1
• Persistent names - forbidden until 2.11.5
• Persistent triggers - forbidden until 3.1.0
