"Go 1.7 has been released" would also be correct, but uses the present perfect tense.
So the question is, can "released" be used as an adjective? "The released version has a bug" seems correct to me, and "released" clearly functions as an adjective there.
All that said, the present perfect version seems clearly correct, while I can't make a great argument for the adjectival version.
Example from nytimes.com right now, "Bag Left Alone by Mother of Olympian Is Blown Up".
(Downvotes: Dunno why either. People are grumpy.)

"Is" combined with "released" does sound odd, but it's not too unusual, like in this sentence: "Heat is released into the atmosphere by cars." (From http://www.merriam-webster.com/dictionary/release)
"Nintendo Wii U is released." - it just sounds strange.
"Nintendo Wii U has been released." - ok, sounds good.
"Nintendo Wii U released." - ok, sounds good.
has been is Passive voice and should be avoided.
In informal writing you should avoid using the passive voice, as it sounds disconnected and boring. Technical articles can sound better in the passive voice though, and I remember my physics teachers always used to berate people for not using it. So we should have written "the experiment is performed" rather than "I performed the experiment".
The is is redundant which may be why it doesn't scan well for you.
GO 1.7 released
Works much better, no?
