v4.15.1.1

- Extend the documentation for `Hakyll.Core.Identifier` (contribution by
    malteneuss)
- Fix yet another regression caused by new dependency checking code
    (contribution by Laurent P. René de Cotret)
- Bump `pandoc` upper bound to allow 2.17 (contribution by Alexander Batischev)
- Website now points to Hackage rather than its own (often outdated) version of
    the docs (contribution by Jasper Van der Jeugt)

v4.15.1.0

- Add `Hakyll.Web.Pandoc.Biblio` functions `readPandocBiblios` and
    `processPandocBiblios`, which let one use multiple bibliographies
    (contribution by Benjamin Eskola)
- Preserve file extension of bibliography files when passing them to Pandoc.
    This enables one to use not just BibTex, but also YAML and JSON files
    (contribution by Benjamin Eskola)
- Fix URL extraction for `srcset` attribute. This affects
    `Hakyll.Web.HTML.relativizeUrls` and other such functions (contribution by
    Alexander Batischev)
- Bump `bytestring` upper bound to allow 0.11 (contribution by Alexander
    Batischev)
- Bump `pandoc` upper bound to allow 2.15 (contribution by Alexander Batischev)
- Bump `aeson` bounds to allow 2.0 (contribution by Alexander Batischev)

v4.15.0.1

- Add missing test file to the package (contribution by Alexander Batischev)

v4.15.0.0

- Fix dependency cycles detector (contribution by Laurent P. René de Cotret)
- Add `--dry-run` to the `build` command (contribution by Fraser Tweedale)
- Add support for Jupyter notebooks (files with ".ipynb" extension)
    (contribution by fedeinthemix)
- Add `Hakyll.Web.Pandoc.Biblio.processPandocBiblio`, which works with `Item
    Pandoc` and is thus composable with other Pandoc-related compilers and
    functions (contribution by fedeinthemix)
- Speed up the runtime by about 9% (multiple contributions by Fraser Tweedale)
- Tolerate unexpected cache misses by recompiling the item; now there is no need
    to rebuild the entire site to fix cache corruption (contribution by Fraser
    Tweedale)
- Replace `Hakyll.Core.Rules.forceCompile` (introduced in 4.14.1.0) with
    `Hakyll.Core.Compiler.recompilingUnsafeCompiler`. The new facility is more
    versatile and composes better (contribution by Fraser Tweedale)
- Remove dependency on `array` (contribution by Laurent P. René de Cotret)

v4.14.1.0

- 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
    jaspervdj#850 (contribution by
    Laurent P. René de Cotret and Vaibhav Sagar)
- Fix binary's name in the first tutorial (contribution by Alexander Batischev)
- Fix "Empty 'do' block" error in GitHub tutorial (contribution by
    alexandroid000)
- Move #hakyll IRC channel from Freenode to Libera.Chat (by Alexander Batischev
    and henk)
- Replace dependency on `cryptonite` and `memory` with dependency on `hashable`
    (contribution by Laurent P. René de Cotret)
- Bump `file-embed` upper bound to 0.0.15 (contribution by Alexander Batischev)
- Bump `optparse-applicative` upper bound to 0.16 (contribution by Felix Yan)
