The currents devs are on files and images.
I think released about the 15th of december.
BLOB is a good idea, even if it not used a lot. To be complete Cook must integrate all of the basic natives of MYSQL.
But unfortunatly, because lot of users are waiting for the files and images management, I prefere limitate the functionality and relase it.
BLOB will be integrated further with a low priority.
If some users are interrested too, please post and comment this post.
