and `Pit`_.
* `BastianPoe`_ has added the long-awaited feature to automatically skip the
OCR step when the PDF already contains text. This can be overridden by
setting ``PAPERLESS_OCR_ALWAYS=YES`` either in your ``paperless.conf`` or
in the environment. Note that this also means that Paperless now requires
``libpoppler-cpp-dev`` to be installed. **You'll need to run
``pip install -r requirements.txt`` after the usual ``git pull`` to
properly update**.
* 1.1.0
* Fix for `#283`_, a redirect bug which broke interactions with
paperless-desktop. Thanks to `chris-aeviator`_ for reporting it.

Notably, you should confirm how you access your Python3 installation. Many
Linux distributions will install Python3 in parallel to Python2, using the names
``python3`` and ``python`` respectively. The same goes for ``pip3`` and
``pip``. Running Paperless with Python2 will likely break things, so make sure that
