Thanks for the release!

FYI, there are various missing *.tar.xz files in the SHA256SUMS file in

http://downloads.haskell.org/~ghc/7.10.2/

I suspect this may be due to the (Content Delivery Network (CDN) caches being stale. Unfortunately this seems to be a persistent issue. You can likely fool the CDN by inserting superfluous / characters in the URL (thanks to Herbert for the tip). For instance, http://downloads.haskell.org/~ghc/7.10.2///SHA256SUMS Cheers, - Ben

This gives me error 404.

I'm not sure what else to say other than to suggest adding superfluous `/` characters to the URL as mentioned previously. The document is there, the CDN just still hasn't realized it. Cheers, - Ben

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? James On Thu, Jul 30, 2015 at 2:07 PM, Ben Gamari wrote:

Hello again!

See below for an important announcement regarding the `text` issue described earlier.

===================================================================== The (Interactive) Glasgow Haskell Compiler -- version 7.10.2 =====================================================================

The GHC Team is pleased to announce a new bug-fix release of GHC, 7.10.2.

There have been a number of significant bug fixes since the 7.10.1 (with over 70 defects fixed). These include fixes affecting type-checker correctness, runtime stability, and compiler performance. For this reason we highly recommend that users of 7.10.1 upgrade quickly.

Note that due to changes made in this release to GHC's optimizer, previously fragile-but-working rewrite rules may fail to fire. One example of this was found in the widely-used `text` package late in the release cycle, which manifested in long compilation times and poor code generation for `Text` literals (see [Trac #10528]). Users are advised to use text >=1.2.1.2 which includes more robust rewrite rules.

It has been brought to my attention that the fix included in text-1.2.1.2 does not in fact fix the rule issues triggered by GHC 7.10.2 (see the later comments on #10528 for details). I have pushed text-1.2.1.3 to Hackage which finally resolves this issue.

Users of GHC 7.10.2 should upgrade to text >=1.2.1.3 at their earliest convenience.

Cheers,

- Ben

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
