I think I have to create it myself, there was some permission issue with github, I had no time to figure-out, so I disabled docker build for contributors. I'll re-create the release once I merge your pending PR, I'll give it a quick look after your fixes, and merge hopefully soon, and then will do the release.

@hjames9 ignore my previous comment, Friday night for me :). For some reason I thought you're creating a new release... :)

@gemyago Haha, no worries. This is just an upgrade to Gateway API 1.6.0, which only really affects TCPRoute and UDPRoute for this library, so it's a relatively simple change.
