Added

• /cm toggle. Every player can switch vein mining off and on for themselves, and the choice survives restarts (stored in stats.yml). Permission caveminer.toggle, on by default. %caveminer_enabled% shows the current state.
• disabled-worlds: worlds where vein mining never triggers, for creative or plot worlds.
• hunger.exhaustion-per-block: makes a vein cost hunger for every extra block. 0.005 matches mining by hand. Default 0, so nothing changes until you set it.

Changed

• First stable release with the Folia support from 1.2.0-BETA, so servers on the default release update channel get it as well.

Existing servers: the new options are not added to an existing config.yml. Without them the plugin behaves as before.
