    🚀 (Release logo by Fabian Neuschmidt)

    🚀 For this release, 32 people from all over the world have contributed
    about 200 commits over almost two months.

    🚀 The focus of this release is certainly on the usability of coala.
    ✅ Usability testing has made us aware of some important difficulties,
    👉 users have to face when trying out coala. We have implemented a lot of
    countermeasures to lower this barrier.

    The changelog below summarizes the most important user facing changes.
    Not listed are especially lots of internal improvements and
    📚 documentation fixes.

    🆕 New Features:

    • Shell
      ✅ Autocompletion
    • Patches are shown without prompting the user if small enough,
      otherwise diffstats.
    • 📇 Bears have metadata and can be browsed. Browse the bear
      📚 documentation
      repository for more information on all the bears.
    • Lots of usability improvements! coala will suggest using certain
      🔧 options if no meaningful configuration was supplied.
    • The help was revamped completely and is way easier to read.
    • A --verbose alias is available for -L DEBUG.
    • 0️⃣ The default_actions setting accepts globs for bears now.
    • The --apply-patches argument was added to automatically apply
      all patches.
    • 👍 coala supports experimental caching. This can lower the run time to
      a fraction of the time needed to perform the full analysis. It will
      🚀 be enabled by default in the next release. To use it, invoke coala
      with --changed-files.
    • Bear showing is divided into a new set of settings: --show-bears
      👉 shows all bears, --filter-by-language allows to filter them,
      --show-details and --show-description allow changing verbosity
      of the output.

    🔋 Feature Removals:

    • 🏷 Tagging was removed.
    • 👕 linter does no longer show the executable of the bear by default.

    🐎 Performance Improvements:

    • Globs will be internally cached now so they don't need to be
      retranslated every time. This may show improvements of several
      seconds when working with a large set of files.
    • 👀 coala supports experimental caching. See New Features for
      more information.
    • coala does not delete *.orig files on startup anymore. This was a
      🐎 huge performance hit especially on HDDs or big file trees. The
      cleanup can be performed manually by running coala-delete-orig.
      Instead coala will keep track of *.orig files more smartly.

    🛠 Bugfixes:

    • **.py can again be used instead ** /*.py.
    • 🌲 If errors happen before the initialization of logging, tracebacks
      will be shown.

    For bear writers:

    • Bears can have a number of attributes now, including author
      👍 information, supported languages or categories. A requirements
      attribute will help generating requirements definition files more
      easily in the future.
    • 👕 The linter wrapper provides a result_severity and a
      result_message parameter now.
    • Bears can now delete and rename files.
    • The LanguageDefinition doesn't need a language_family anymore to
      load language definitions.
    • Results can be created directly from the Bear class more
      conveniently with self.new_result(...).
