From the Stackage side: I'm happy to provide testing and, even better, support to get some automated Stackage testing tied into the GHC release process. (Why not be more aggressive?

Let me play devil's advocate though: having a large number of versions of GHC out there can make it difficult for library authors, package curators, and large open source projects, due to variety of what people are using. If we end up in a world where virtually everyone ends up on the latest point release in a short timeframe, the problem is reduced, but most of our current installation methods are not amenable to that. We need to have a serious discussion about how Linux distros, Haskell Platform, minimal installers, and so on would address this shift. (stack would be able to adapt to this easily since it can download new GHCs as needed, but users may not like having 100MB installs on a daily basis ;).)<br><br></div>What I would love to see is that bug fixes are regularly backported to the stable GHC release and that within a reasonable timeframe are released, where reasonable is some value we can discuss and come to consensus on.

<br>
An interesting topic came up over dinner tonight: what if GHC made more releases? As an extreme example, we could release a new point version every time a bug fix gets merged to the stable branch. This may be a terrible idea. But what's stopping us from doing so?<br>
<br>
The biggest objection I can see is that we would want to make sure that users' code would work with the new version. Could the Stackage crew help us with this? If they run their nightly build with a release candidate and diff against the prior results, we would get a pretty accurate sense of whether the bugfix is good. If this test succeeds, why not release? Would it be hard to automate the packaging/posting process?<br>
<br>
The advantage to more releases is that it gets bugfixes in more hands sooner. What are the disadvantages?<br>

PS: I'm not 100% sold on this idea. But I thought it was interesting enough to raise a broader discussion.<br>
