Saw this message at the top of my plugin today and decided I should fix that.
I updated my readme.txt file to say:
Requires at least: 5.0
Tested up to: 5.4.1
Requires PHP: 5.6
Stable tag: 1.1.8
License: GPLv2 or later
I committed changes almost 6 hours ago and it still says this message at the top. Did I miss somewhere else that I'm supposed to update to get this message to go away? I can barely find any information on how to deal with this kind of an issue.
