I am not sure why the report above says 3 lines are missing, which are from a Julia version pre 1.1, while the tests all pass. But besides that this should be good to go (even with updated News.md).

[mateuszbaran]

There are three lines that keep being not counted correctly so I'd ignore it.

Have you actually committed the updates to News.md? I don't see them.

[kellertuer]

Of course I committed them! But you are right, I should probably also have pushed them 😴
