[TYPO3-dev] Defining TCA settings for different TYPO3 versions

[Thomas "Thasmo" Deinhamer]

Hello folks!

What would be the best way to define/overwrite TCA
settings for different TYPO3 versions?

The specific TCA I'm talking about tends to be quite
large - would it be okay to create separate files for
each newer TYPO3 versions, which would hold additional
TCA settings overriding the default tca.php definitions?

And what's the correct way to determine the TYPO3 version?

Thanks,
Thomas
