Hello fellow GHC devs, As some of you might have noticed, I added a changelog.md file to libraries/base: https://github.com/ghc/packages-base/blob/c8634027d4e3315a2276fb1be8168c4864... (please feel free to fix any typos/omissions/whatever you notice) My hope/motivation is that since Hackage gained the ability to display changelog files, the rather extensive changes in `base` might be a bit more easily/conveniently accessible on Hackage. I chose to use Markdown format, as I believe it may be more convenient to maintain/edit the `base` changelog as plain text rather than having to edit XML after each noteworthy change in `base`. And as the release-notes typically only exploit a subset of the Docbook facilities, the conversion to Docbook XML could be performed semi-automatically shortly before a release. Moreover, the release notes from previous major GHC release (which in the past contained the major changes in `base` et al.) are usually removed again. While a separate changelog file would usually retain (more) version history. Therefore, I'd propose to switch from editing the user's guide release note for library release notes to using Hackage-changelog files in Markdown format (following a common structural convention) and make it the release-manager's responsibility to integrate the respective package's changelog content into the user's guide. Any comments? Cheers, hvr
