Re: when has a BIP been merged?

Is there an easy way to know whether a given BIP has been merged or whether its still in work?

These are BIPs implemented in bitcoin core. Its not necessary that you will find all the BIPs in this list.

I didn't said that those are all the BIPs, I answered his question of an easy way to know if a BIP is merged. (having a list is easier than reading all the BIPs)
As for the software, OP didn't specified so it's best to assume that he's talking about the reference client.
