注意：确保版本号包含了三个部分。

NOTE: Make sure that the version number includes three parts.

第一个是指示版本号无效的信息。

The first is our message indicating the invalid version number.

名称中的版本号保证了未来的兼容性。

A version number in the name guarantees compatibility in the future.

主版本号表明程序库版本之间的潜在不兼容性。

A major number indicates a potential incompatibility between library versions.

不仅如此，这还会导致标准成为事后诸葛亮——想解决问题时(例如奇数的版本号)却发现已经太迟了。

Not only that, but the standard was an after-the-fact write-up, which meant that by the time it came to fix problems (such as odd version Numbers) it was already too late.
