[TYPO3-dev] [Typo3-Dev] indiscriminate of i18n and languages in typo3.

[Dennis Cheung]

Hi Kazper,

How will 4.0 backwards compatible to 3.8?
I mean, who will not able to upgrade?

I know typo3 since 3.8. But I see there are still have many
incompatible to 3.5 version. (e.g. user auth service). It may be not
done in 4.0 release, but not late as 5.0.
