There was talk from an earlier email thread of releasing the Haskell Platform at the same time as 7.10.2.

I am referring to the weekly news of 2015/05/11: https://ghc.haskell.org/trac/ghc/blog/weekly20150511

and this email thread: https://mail.haskell.org/pipermail/ghc-devs/2015-May/008911.html

Was this plan abandoned? Or was there something unexpected that is delaying it?

Not at all! There ended up being a bit of timing skew between the Platform and GHC releases but an approximately concurrent release is still the plan. The Platform folks are hard at work as we speak, in the final stages of pushing out their release. I expect it will be announced shortly. Unfortunately due to the late notice of the text issue, the initial release will ship with text-1.2.1.1, which is still affected by the rewrite issue. That being said, the impact of this issue is mostly on compile time, in most cases you shouldn't see much impact on runtime performance. Moreover, they will be working to push out another release with text-1.2.1.3 in the coming days. Cheers, - Ben
