- Add `Hakyll.Web.Html.demoteHeaderBy` function, which demotes an HTML header by
a given amount (contribution by Logan McGrath)
- Add `Hakyll.Core.Rules.forceCompile` modifier which forces re-compilation of
an item even if its file wasn't modified. This is useful for data sources
which aren't local files (contribution by Fraser Tweedale)
- Add `Hakyll.Web.Tags.getTagsByField` which extracts tags from a given field
instead of the default "tags" field (contribution by Jim McStanton and
Alexander Batischev)
- Add `Hakyll.Core.Configuration.shouldWatchIgnore` function and the
corresponding `watchIgnore` field for `Configuration`. These are used to
ignore files in watch mode, which is useful when certain files are
pre-processed and the results are saved into the provider directory
(contribution by Aron Erben)
- Add `Hakyll.Web.Meta` modules `JSONLD`, `OpenGraph`, and `TwitterCard`. These
help with semantic web metadata in pages. This adds dependency on `aeson`
(contribution by Fraser Tweedale)
- Export `Hakyll.Web.Pandoc.Biblio.unCSL` function (contribution by Benjamin
Bray)
- Make the runtime concurrent, which brings 30% speedups on real-world sites.
This adds dependencies on `array` and `lifted-async`. Please note that it
doesn't scale past the number of physical cores; ideas are welcome in
