Key takeaways

  • Server security: malicious clients can no longer force a server to freeze or to run out of memory (MC-79079, MC-79612).
  • Public flaw: the out-of-memory exploit, which affected 1.8.3 and earlier, had been published days before by its finder, who said he first reported it in 2013.
  • Recommended: the update was optional, but Mojang highly recommended it.
