[TYPO3-mvc] How stable do you consider the API?

[Nikolas Hagelstein]

Hi,

I start using it at a very early state (prior to the persistence rewrite)
and everything went way more smoothly than expected.
Regarding the api changes you are right. During the development process I
constantly updated extbase/fluid.
Remarkably even "!!!" did not cause huge project adjustments.

As the project went live I split it up to a live and development branch each
using a different T3 environment. 
Everytime a bigger "change/update" makes it to live i update
extbase/fluid at live as well, after testing of course.

Did that several times meanwhile without any problems. 

Furthermore I wrote some unit tests to ensure that the most vital functions
are properly working after an extbase/fluid upgrade. 
That's something I would highly recommend.

Cheers,
Nikolas
