GHC is packaged for a number of operating systems and distributions. While they may lag behind the latest GHC release, advantages such as dependency checking and ease of uninstallation mean we recommend using them anyway, unless you have a particular need for new features or bug fixes.

Each night, our nightly build system runs a full bootstrap and test cycle on several architectures. The source tree for this snapshot, and some binary distributions generated by the build, are put up for download. The source tree is downloaded from the darcs repositories at the time of the build, and will be tagged with a version number of the form x.yy.YYYYMMDD where YYYYMMDD is the date of the build. See here for an explanation of GHC's version numbering policy.

The stability of these snapshots is by no means guaranteed, but the nightly build/test logs are sent to the cvs-ghc mailing list, so by watching that list you should be able to get a clue as to which snapshots are more stable. The build logs for the most recent build are also available below.

HEAD branch (development snapshots):

• Download snapshot distributions
• Documentation
• Check build status

STABLE branch (snapshots along the stable branch; release candidates for the next patchlevel release):
