Everything looks fine but starting with the ex.27 (line 1895, Using a renamed or deprecated procedure), the first tab is still 'Neo4j code' despite the fact that in the code the order is opposite. I don't understand why.

Another questions is about titles: Will we change 'category' to 'notifications' in 'Unsupported category', 'Security category', 'Topology category', and 'Schema category'?

On the first question, it's a bug. We need to ask DocOps to fix it.
And on the second question -> Good catch. I'll fix that in this PR. Thanks a lot!

Thanks for the documentation updates.

The preview documentation has now been torn down - reopening this PR will republish it.
