- Re-removes Bukkit#getServerName - This was (hopefully?) only added back for Timings v2. It should be kept in that scope. - Intend to let PlayerViewDistance API slip. Given the scope of the changes in this area it seems best to let this slip past initial release. It can be re-added when there is additional time to focus on it and the changed systems it relies on. If it is fixed prior to release this is implemented as a single shim patch that can be dropped.
