For security reasons it is recommended that all users upgrade to Minecraft 1.8.3 by re-running BuildTools. A fix for 1.8 is also available via the --rev 1.8 argument. At this stage there is no fix for 1.7.10 or below, however given these builds have been unsupported for more than 7 months, we recommend that all servers look into upgrading. For those using Vanilla, a 1.8.4 version with these same fixes has been released by Mojang.
