Typo3 core gets updated every 6-12 months. At least the last ones.

Normally the T3 core stays downward compatible. That means that at least for some
version numbers every feature will be availbale. This gives the extension authors
some time to change theier coding to newer concepts.

When a feature comes outdated like the old "language split" fields then they will be
removed some time (which becoes true for the language split feature in some time).
