New builds are available to support the new doors & fence gates added in Minecraft 1.8 on Jenkins. Use build #926 or higher.

You will not be able to protect the new doors & fence gates by default if you already have LWC installed. If you want them to be protectable, you must edit plugins/LWC/core.yml and add the new blocks to the protections.blocks section. For example:

    blocks:
        chest:
            enabled: true
            autoRegister: private
        furnace:
            enabled: true
            autoRegister: private
        dispenser:
            enabled: true
            autoRegister: private
        sign:
            enabled: true
            autoRegister: private
        wooden_door:
            enabled: true
        iron_door:
            enabled: true
        spruce_door:
            enabled: true
        birch_door:
            enabled: true
        jungle_door:
            enabled: true
        acacia_door:
            enabled: true
        dark_oak_door:
            enabled: true
        trap_door:
            enabled: true
        fence_gate:
            enabled: true
        spruce_fence_gate:
            enabled: true 
        birch_fence_gate:
            enabled: true
        jungle_fence_gate:
            enabled: true
        acacia_fence_gate:
            enabled: true
        dark_oak_fence_gate:
            enabled: true
        trapped_chest:
            autoRegister: private
            enabled: true

Notice the added spruce_door down to dark_oak_door and spruce_fence_gate to dark_oak_fence_gate.

Once you've added those to your config, restart the server and you will be able to protect the new doors & fence gates!

Banners are fully supported as of LWC build #925

To protect banners, you can add these to your blocks config:

        standing_banner:
            enabled: true
        wall_banner:
            enabled: true

Iron Trapdoors are fully supported as of LWC build #926

To protect iron trapdoors, you can add these to your blocks config:

        iron_trapdoor:
            enabled: true

Note: As of the new version they are protected by default in new installs, so your config may already contain this.
