The yellow box in the upper right of your analysis mentions analysis warnings – what are they?

:warning: Make sure you upgrade to SonarQube v9.9 LTS soon, not only to benefit from our Best LTS Ever™, but because soon we will systematically ask users to upgrade when they ask questions about earlier versions of SonarQube, which are now considered unsupported. :smiley:
