Added

• /lv status [player] shows whether night vision is on, automatic, blocked or comes from somewhere else. The same value is available as %lightvision_state%.
• darkness-trigger.hysteresis. Automatic night vision stays on until the light is a few levels above the threshold, so it no longer flickers on and off at the edge. Default 2.
• New options are added to an existing config.yml automatically on start and on /lv reload. The previous file is kept as config.yml.bak.

Changed

• The default world-blacklist holds example_world instead of world_nether. Existing configs keep what they have.

Fixed

• Night vision could get stuck after a restart or a rejoin. The effect is infinite and was saved in the player data, and the plugin did not remember it had given it out, so /lv could no longer remove it. The effect is now taken away when a player leaves or the plugin stops, and picked up or cleaned up on join.
• Night vision was lost on death and after drinking milk until the next rejoin. It comes back on its own.
• Automatic night vision no longer stays missing after death or milk while the player is still in the dark.
• Blocking a player now plays the fade flash like switching off does, as the config describes.
• /lv tab completion no longer suggests on and off after reload.
