If you want 1.8 support, you have to download new updates from the GitHub Releases page.
Added support for particles that need extra data (REDSTONE, FALLING_DUST, BLOCK_DUST, BLOCK_CRACK, ITEM_CRACK)
See the bottom of the overview page on how to make use of those
Added an option to enable the advanced grid for the clipboard selection as well
See the new config field 'advanced-clipboard-grid'
If you were using an older version of the plugin and you want to use the new field, you'll have to either add it manually or delete your old config (if you don't want to use it, you don't have to delete it)
