The implemenation of one language binding to one object version is virtual.... Meaning potentually you can still edit more then one language per version.
You're right, I can edit more than one language before to publish.
But it does made impossible to use static caching with multilanguage portal as everytime I change something in one language version of an object, I have to regenerate all 9 languages static cache.
I understood (or hoped for...) that the improved multi language system will cut this as it has an horrible impact on performance. A simple edit become a batch publishing.... Any possibility to turn this around?
