(This update includes some important performance and stability fixes. I recommend all users to update.)
Changes:

• Added a bunch of new commands to add/remove/view prefixes and suffixes for users and groups
• Fixed an issue that meant temporary permissions couldn't be removed
• A bunch of enhancements for PermissionsEx migration. (Many thanks to @Boomclaw for the super valuable help & advice)
• Fixed a really stupid resource leak with SQL backed datastores. Should significantly improve performance.
• Made group/server/track naming much more flexible
• Fixed applying wildcard permissions on Bukkit.
• Made the output of listnodes nicer to read
• Added a config option to toggle log notifications in-game
• Fixed an exception with getting suffixes from Vault
• Other misc changes with the Vault permissions hook to make the LuckPerms implementation more closely match what is documented within the Vault API.
