因为最近发生的网络攻击，论坛目前仍处于维护状态。我们在这里给大家更新最新的消息和新闻，以下是本周更新的一些消息。

这里感谢大家帮助我们一起打磨最终的发布版，请大家记得去 UE4 问答中心的 Bug 反馈 版块提交任何发现的问题。
八月的 #ue4jam 更新
这个活动在本月得到了很棒的效果，有 48 个作品提交，本次主题是“事物并不总是他们表现的样子”。这次的结果原计划是在周四的 Twitch 上揭示，然而由于无法从论坛的讨论贴中下载游戏，我们不得不推迟公布结果。对于在急切等待结果的各位我们表示非常抱歉，同时我们也在寻求方案避免在将来出现同样的情况。
本周的直播将暂停
这可是第一次啊，由于上述的问题，我们不得不取消原定于周四在 Twitch.tv/UnrealEngine 的直播计划。下周会重新回归周二的培训课程系列以及在周四会给大家一个商城里的惊喜，还有八月 #ue4jam 的比赛结果。我也已经迫不及待的想给各位带来更新话题了。
在这里我们要再次感谢各位的耐心，我们仍在调查并尝试解决论坛被攻击的问题，并为给各位带来的不便深表歉意。请大家关注 博客 和我们官方的 Twitter 帐号（译者：还有微博帐号）以便及时得到更新。
