Of course you don't, you have no idea what you're talking about. These "big" updates are not big. Currently there is a very small team that is working on cs, not only that but they use old engine with spaghetti code which makes everything harder and it's easy to break something. If valve actually had interest in cs they would push these updates once a month at least, currently there is no need for that because cs is still popular. Please educate yourself on that matter, you sound highly uneducated on that matter.
