BLU's updates happened in 4.5 5.15 and 5.45
I think it's safe to assume it's not getting updated til much later this year.

It's a fun thing to do on the side and the savage content can be a good challenge, but the job is too OP to lose its limited status. I see talk of more limited jobs and I don't see the point or how it would even function. One limited job is enough and it has so much flexibility.

I'd rather wait til we actually get to that New World to see a story / spell update than have them try to wedge in Shadowbringers content.
