- Fix "thread blocked indefinitely in an MVar operation" errors caused by
    exceptions produced by `Items` (#1014) (contribution by Jasper Van der Jeugt)
- Improve `+watchServer` and `+previewServer` error messages: they now explain
    *how* to enable the flag when the user tries to run `watch`/`preview`

    Batischev, Adrien, Tanya Bouman)

v4.16.0.0

- Bump `base` *lower* bound to 4.12 (GHC >= 8.6). Hakyll already failed to build
    on earlier versions due to the template-haskell requirement, and nobody

    dropped (contribution by Alexander Batischev)

    Batischev)

    Aviv Burhanudin, Jacek Galowicz, Daniel Mlot, Yoo Chung, Robert Pearce)

    `check`, `clean` etc.) (contribution by Alexander Batischev)
- Add a `Hakyll.Core.Configuration.Configuration.previewSettings` field which
    lets the user override the settings used by the preview server (contribution
    by Christopher League and Brian McKenna)

    (contribution by Robert)

    spec compliance (contribution by ncaq)
- Add a `Hakyll.Core.Configuration.Configuration.checkHtmlFile` predicate which
    dictates what files will get link-checked by the `check` command. Default
    predicate accepts files with .html and .xhtml extensions (contribution by
    Yoo Chung, with earlier contribution from Michael Orlitzky)

    Alexander Batischev)
- Allow `pandoc` 3.0. Note that the behavior of Hakyll's `readPandocBiblios` and
    `readPandocBiblio` is different whether pandoc 2 or 3 is installed
    (contribution by Laurent P. René de Cotret)
- Bump `mtl` upper bound to allow 2.3 (contribution by Alexander Batischev)
- Bump `pandoc` upper bound to allow 3.1 (contribution by Laurent P. René de
    Cotret)
- Bump `template-haskell` upper bound to 2.21 and `time` to 1.12 (GHC 9.6.1)
    (contribution by Laurent P. René de Cotret)

v4.15.1.1

    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- Website now points to Hackage rather than its own (often outdated) version of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

    `Hakyll.Web.HTML.relativizeUrls` and other such functions (contribution by

    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
    #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)
