### New Features

- **Leaf Decay Flag** — Claim owners can now prevent leaves from decaying naturally inside their claims, protecting tree-based builds.

- **Chorus Fruit Teleport Flag** — Claim owners can now block untrusted players from teleporting into claims using chorus fruit.

- **Vehicle Placement Flag** — Claim owners can now prevent untrusted players from placing boats and minecarts inside their claims.

- **Crop Trample Flag** — Farmland inside claims is now protected from being trampled by entities. Claim owners and trusted players can still trample their own crops.

- **Lightning Damage Flag** — Claim owners can now prevent lightning strikes from damaging blocks and starting fires inside their claims.

- **Resize Tool** — The resize tool now fully works. After using the resize command, left-click and right-click blocks with the stick to set new boundaries. The resize applies automatically once both corners are selected, with proper size and overlap validation.

- **Explosion Protection** — Explosions from all sources (creepers, TNT, beds, respawn anchors, etc.) are now properly blocked inside claims when the explosions flag is disabled.

- **Fire Spread Protection** — Fire spreading, lava ignition, and unauthorized flint and steel usage are now properly blocked inside claims when the fire spread flag is disabled.

- **Mob Spawning Control** — Hostile mobs and passive animals are now properly blocked from naturally spawning inside claims based on their respective flags.

- **Item Pickup Protection** — Untrusted players can now be prevented from picking up items inside claims.

- **Item Drop Protection** — Untrusted players can now be prevented from dropping items inside claims.

- **Expanded Container Protection** — Hoppers, droppers, dispensers, and brewing stands are now protected alongside chests, barrels, furnaces, and shulker boxes.

- **Expanded Interaction Protection** — Note blocks, jukeboxes, beacons, anvils, and enchanting tables are now protected from untrusted player interaction.

- **Projectile PvP Protection** — Arrows and other projectiles shot by players are now properly blocked by PvP protection, not just direct melee attacks.

### Changes

- Vault is now optional. The plugin will load and function without Vault installed. Economy features simply become unavailable and display a clear message if a player tries to use them.

- Claim owners can now always build, break, and interact inside their own claims regardless of flag settings. The build flag now only controls whether trusted players can build.

- Claim size is now calculated consistently everywhere as a 2D area (width times length in blocks). Previously, creating a claim used area but removing, listing, and inspecting claims used volume, which caused refunds to return far more blocks than were originally spent.

- Claim size calculation now correctly counts inclusive blocks. A claim from coordinate 0 to coordinate 10 is now properly counted as 11 blocks wide, not 10.

- The claim info command now properly displays entry and exit message flags as text instead of showing them as true/false.

- All button types (stone, wooden, etc.) are now protected inside claims, not just one specific type.

- The flag system has been extracted into its own dedicated structure where each flag carries its own default value and description, making flag management cleaner and more maintainable.

- The flag help command now pulls descriptions directly from each flag's definition, keeping help text always in sync with actual flag behavior.

- Backups now save the latest data before creating the backup copy, ensuring backups contain the most current information.

- Claim boundary visualization now correctly shows the full extent of claimed blocks by including the far edges.

### Bug Fixes

- Fixed a crash when trying to buy claim blocks without Vault installed.

- Fixed claim owners being blocked from building inside their own claims because the build flag defaulted to off.

- Fixed a crash that could occur when loading claims from worlds that are no longer loaded on the server.

- Fixed the spatial lookup grid producing wrong results for claims in negative coordinates.

- Fixed the reload command causing duplicate claims to appear because old data was not cleared before reloading.

- Fixed a crash that could occur when removing a claim from a world that had no other claims registered.

- Fixed a crash that could occur when checking claim ownership at locations with no valid world.

- Fixed the plugin failing to start entirely if Vault was not installed, even though economy features are optional.

- Fixed the overlap check creating invalid temporary data during validation.

- Fixed the claim tool matching being too strict, causing tools with any durability change to stop working.
