Scala 2.7.2-RC5

今天下午才升级到了Scala 2.7.2-RC4，没想到Scala team以迅雷不及掩耳之势，今天发布了2.7.2的RC5。根据Scala-lang主页上的说明，感觉这应该是2.7.2正式release之前的最后一个RC了。

We are taking particular care in polishing Scala 2.7.2, also considering that 2.7.2 will be the reference release for the "Programming in Scala" book, currently in print. This RC5 should really be our last release candidate for this release cycle, and should be shortly followed by the final release.

不过到现在，scala-tool的maven repository中，还没有rc4和rc5的版本。
