Blacklisted versions are versions that are known to cause major issues or contain security concerns and have thus been blacklisted by the Obsidian team. Obsidian will disable plugins on startup whose installed version is blacklisted. Released while not listed versions happened outside the period where the plugin was present in the community plugin list and are excluded from aggregate release statistics.
