[ANNOUNCE] GHC 8.6.4 is now available
Hello everyone, The GHC team is very happy to announce the availability of GHC 8.6.4, a bugfix release in the GHC 8.6 series. The source distribution, binary distributions, and documentation for this release are available at https://downloads.haskell.org/~ghc/8.6.4 The 8.6.4 release fixes several regressions present in 8.6.3 including: - A regression resulting in segmentation faults on Windows introduced by the fix for #16071 backported in 8.6.3. This fix has been reverted, meaning that 8.6.4 is once again susceptible to #16071. #16071 will be fixed in GHC 8.8.1. - A bug resulting in incorrect locking on Darwin, potentially resulting in hangs at shutdown (#16150) - A few bugs in the profiled runtime resulting in the potential for memory unsafety has been fixed (#15508). - The `process` and `transformers` libraries shipped now properly reflect released Hackage releases (#16199) - A bug where TH name resolution would break in a plugin context has been fixed (#16104) - Compilers that do not support TemplateHaskell no longer advertise such support in `--supported-languages` (#16331) As a few of these issues are rather serious users are strongly encouraged to upgrade. See Trac [1] for a full list of issues resolved in this release. Note that this release ships with one significant but long-standing bug (#14251): Calls to functions taking both Float# and Double# may result in incorrect code generation when compiled using the LLVM code generator. This is not a new issue, it has existed as long as the LLVM code generator has existed; however, changes in code generation in 8.6 made it more likely that user code using only lifted types will trigger it. Note also that this is the first release cut from our (yet again) revamped continuous integration infrastructure. While we have done a great deal of checking to ensure that the build configuration reflects that of previous releases, do let us know if something looks off. Happy compiling!

Final steps in GHC's Trac-to-GitLab migration
Hi everyone, Over the past few weeks we have been hard at work sorting out the last batch of issues in GHC's Trac-to-GitLab import [1]. At this point I believe we have sorted out the issues which are necessary to perform the final migration: * We are missing only two tickets (#1436 and #2074 which will require a bit of manual intervention to import due to extremely large description lengths) * A variety of markup issues have been resolved * More metadata is now preserved via labels. We may choose to reorganize or eliminate some of these labels in time but it's easier to remove metadata after import than it is to reintroduce it. The logic which maps Trac metadata to GitLab labels can be found here [2] * We now generate a Wiki table of contents [3] which is significantly more readable than GitLab's default page list. This will be updated by a cron job until underlying GitLab pages list becomes more readable. * We now generate redirects for Trac ticket and Wiki links (although this isn't visible in the staging instance) * Milestones are now properly closed when closed in Trac * Mapping between Trac and GitLab usernames is now a bit more robust As in previous test imports, we would appreciate it if you could have a look over the import and let us know of any problems your encounter. If no serious issues are identified with the staging site we plan to proceed with the migration this coming weekend. The current migration plan is to perform the final import on gitlab.haskell.org on Saturday, 9 March 2019. This will involve both gitlab.haskell.org and ghc.haskell.org being down for likely the entirety of the day Saturday and likely some of Sunday (EST time zone). Read-only access will be available to gitlab.staging.haskell.org for ticket lookup while the import is underway. After the import we will wait at least a week or so before we begin the process of decommissioning Trac, which will be kept in read-only mode for the duration. Do let me know if the 9 March timing is problematic.

Re: [Haskell-cafe] Final steps in GHC's Trac-to-GitLab migration
This look great, thanks to everyone involved! Some feedback: - When I click to the "Wiki" link on the left it opens "Home" page and I don't know how to go to the index from there. I think we may want index to be the home page for the wiki? - Redirects don't seem to work: https://gitlab.staging.haskell.org/ghc/ghc/wikis/commentary/rts/heap-objects - Comparing these two pages: https://ghc.haskell.org/trac/ghc/wiki/Commentary/Rts/Storage/HeapObjects?redirectedfrom=Commentary/Rts/HeapObjects https://gitlab.staging.haskell.org/ghc/ghc/wikis/commentary/rts/storage/heap-objects The Gitlab page doesn't have images that Trac page has. Secondly, the "_|_" string used in the Trac page is migrated as italic "|" in Gitlab.
