@bb15 I understand your concern, and I apologise for the inconvenience caused.
To answer your question yes, we do test before releasing. Both automated tests as well as manual tests by two persons, but this display issue was missed unfortunately. The current automated tests do not test the output on the dashboard yet. The fix will be released any minute now.
However, the php error we introduced yesterday on the 1.5.0 release can’t be caught by automated test as this was a missing file on the repository, while this file was present on GitHub: the tests ran without issues. The WordPress repository requires new files to be explicitly pushed separately. While we have a checklist for a WordPress release, we accidentally missed this step, causing in discrepancy between the GitHub version and the one on the repository.
To prevent such issues in the future we will add more front-end automated tests, and extend our manual test checklist.
If you’re interested, you can join our beta test program, we welcome input from our free and open source community of collaborators, this greatly helps improve our plugin!
Let me know if you’re interested.
