In-app extensions manager does not notify about new release of com.elisseck.civihoneypot
To reproduce, install v 1.0.3 of the extension. Visit the extensions manager, hit refresh. Despite the publication of a release node for v 1.0.5, note that you are not prompted to upgrade. Note that the same is not true for other out-of-date extensions. (On the system where this behavior was discovered, CiviRules was also out of date but showed that an upgrade was available.)
Created as an issue here (rather than in the extension's issue tracker) because -- with the information we have now, anyway -- this seems more like an infrastructure problem than something the maintainer needs to change.
Note that this extension, despite submitting a request, has not yet been flagged for automated distribution. Could it be that extensions which are not whitelisted are treated differently?
