Bukkit

v0.0.5 - [range nerfs (pre-alpha)]

• Adds redstone detector.
• Ranges nerfed! (still hard-coded)
  - iron and redstone: 7
  - gold and lapis: 6
  - diamond and emerald: 5
• Some code improvements...

v0.0.4 - [initial (pre-alpha) release]

• Adds iron, gold, lapis, diamond and emerald detectors.
  - (iron and gold crafted using ore blocks, others crafted using items)
• Range is hard-coded to an 8 block radius (sphere shape).
• Block searches performed in the background to avoid lag.
• Only one detector allowed to be active at a time per player.

There are a lot of possible situations where the detector will still display itself as "[ON]" despite being deactivated. This doesn't affect gameplay.
(I'm not tracking all the events needed for this because small visual glitches like this is very low priority in a pre-alpha: the plugin can "loose track of" the detector item --> it will deactivate the detection mechanic, but the actual item wont have it's lore-text updated.)
(There are some other small issues as well but nothing important.)
