stm-containers-0.2.15 build failures with primitive-0.6.2

[DanBurton]

It seems there are some conflicts with new exports from Data.Primitive.Array. I recommend qualified imports to avoid issues like this.

[DanBurton]

It seems I was wrong about the cause; primitive-0.6.1.0 exports newArray as well. I don't quite understand how this build was passing previously.

[nikita-volkov]

I suspect, this is due to a conflicting release of "base-prelude", which is already deprecated. Just update the the Hackage index and everything should go fine.

[decentral1se]

Well, I'm still seeing this failure after giving it a shot today. Any other hints @nikita-volkov?

[bergmark]

Since this is LTS the new major base-prelude won't be picked up, @lwm you should add a base-prelude < 1.0.2 constraint to the lts build.

[nikita-volkov]

Better base-prelude >= 1.2

[bergmark]

LTS 8 already contains base-prelude 1.0.*
