在下一个版本（0.3.13）里，我打算把内部版本号整数的格式从 313 改成 31300，比如 31305 = 0.3.13.5。最后一个数字代表发布之间的 SVN 变更，应该在版本号里得到恰当体现。否则，万一我们在某个子版本里犯了错、需要绕过去，那会相当痛苦。
In the next release (0.3.13), I'm going to change the format of the internal version number integer from 313 to 31300, for instance 31305 = 0.3.13.5. The last number represents changes on the SVN between releases and ought to be properly represented in the version number. Otherwise, it would be a pain if we had a mistake or something in one of the sub versions that needed to be worked around.
