New setting "handleExploitTNTWaterlog" (default false/disabled) which, if enabled, will cause TNT which explodes in liquid to actually destroy a single adjacent block in all 6 directions. This will only apply to blocks which can be destroyed by TNT normally, specifically anything other than air, bedrock, water, lava, obsidian, and enchanting tables. The destruction of these blocks will be handled as if they had been mined, dropping the appropriate item.

TNT in water/lava doesn't normally destroy any surrounding blocks, which is usually desired behavior. That's the reason this setting is disabled by default. However, it is available because it provides a method to get through waterwalls with enough persistence, and it makes cheap (non-obsidian) TNT cannons require minor maintenance between shots. Both are useful things for my server.
