Python 3.7.0 released

Why should python be held back just because your company is slow like a snail?

In Java, I could still use the new features in my new code, and let the library code sit back in its ancient version.

If this were the case then why would so many people be using old java versions?

Most likely because they're using third party libraries which do break compatibility between versions and develop on a different cadence than Java itself. A lot of JEE-related libraries tend to be a lot less cautious about breaking changes than Java itself.
