Hello,
I have updated today to 5.0.7 (and have reverted again to 4.3.3) because of a changed way global blocks seem to be integrated in the scope of a page.
In an “Archive Layout”, I have a rather complex design of how I want to show individual posts. Because I show this particular design on several places on my website, I have decided to implement it as a global block. The global block itself contains dc-fields of the post. In the Archive Layout, I have enabled a looper provider, and a looper consumer, and inside that consumer is the gloabl block. In 4.3.3., it works: the global block is repeatedly shown, and each instance shows the next post. In 5.0.7, however, each instance of the global block shows the same (the latest) post.
