User blog comment:Kwitz919/Update 1.6.0.1 Beta/@comment-28905095-20180619202513

I've already created the Update 1.6/build 1 to document it, and it has a link to Barrier Block. In that process I renamed the "Invisible Bedrock", as that seemed correct, but when reviewing the history of stuff this might be wrong.

Now it seems like "Invisible Bedrock" was a different thingy used in earlier version, which now gets a similar thingy, now called "Barrier Block", which also is invisible and similar to the previous.

The remaining question is whether this warrants two different pages, or whether it's OK to rename the Invisible Bedrock page (like I've already done).
