The following behavior was reported when using Cljdoc badges on Github:
When refreshing the Github page shortly after a successful build of a newer release version, the link of the Cljdoc badge already resolves to the newer release version, whereas the Cljdoc badge SVG is still showing the old version. This is probably due to our caching configuration for badges.

• We are currently setting max-age to 30 min for badges: https://github.com/cljdoc/cljdoc/blob/master/src/cljdoc/server/pedestal.clj#L332
• To make things more complicated, Github is also doing its own caching: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/about-anonymized-urls#an-image-that-changed-recently-is-not-updating
• There were some previous issues with badgen.net that should be considered when changing the badge caching: Consider options for badge service #422

Maybe an option could be to introduce conditional requests by setting the Last-Modified or ETag response header for badges?
