Hi,
I already tried to update TYPO3 Flow:
>> composer update

Composer returns:
>> Nothing to install or update

(by the way, I just installed TYPO3 Flow last weekend from scratch)

When I type "./flow", it shows the following version (followed by the current context)
>> TYPO3 Flow 2.0 ("Development" context)
