 Paperless offers a couple features that automate certain tasks and make your life
 easier.

-Guesswork
-#########
-
-
-Any document you put into the consumption directory will be consumed, but if
-you name the file right, it'll automatically set some values in the database
-for you.  This is is the logic the consumer follows:
-
-1. Try to find the correspondent, title, and tags in the file name following
-   the pattern: ``Date - Correspondent - Title - tag,tag,tag.pdf``.  Note that
-   the format of the date is **rigidly defined** as ``YYYYMMDDHHMMSSZ`` or
-   ``YYYYMMDDZ``.  The ``Z`` refers "Zulu time" AKA "UTC".
-   The tags are optional, so the format ``Date - Correspondent - Title.pdf``
-   works as well.
-2. If that doesn't work, we skip the date and try this pattern:
-   ``Correspondent - Title - tag,tag,tag.pdf``.
-3. If that doesn't work, we try to find the correspondent and title in the file
-   name following the pattern: ``Correspondent - Title.pdf``.
-4. If that doesn't work, just assume that the name of the file is the title.
-
-So given the above, the following examples would work as you'd expect:
-
-* ``20150314000700Z - Some Company Name - Invoice 2016-01-01 - money,invoices.pdf``
-* ``20150314Z - Some Company Name - Invoice 2016-01-01 - money,invoices.pdf``
-* ``Some Company Name - Invoice 2016-01-01 - money,invoices.pdf``
-* ``Another Company - Letter of Reference.jpg``
-* ``Dad's Recipe for Pancakes.png``
-
-These however wouldn't work:
-
-* ``2015-03-14 00:07:00 UTC - Some Company Name, Invoice 2016-01-01, money, invoices.pdf``
-* ``2015-03-14 - Some Company Name, Invoice 2016-01-01, money, invoices.pdf``
-* ``Some Company Name, Invoice 2016-01-01, money, invoices.pdf``
-* ``Another Company- Letter of Reference.jpg``
-
-Do I have to be so strict about naming?
-=======================================
-
-Rather than using the strict document naming rules, one can also set the option
-``PAPERLESS_FILENAME_DATE_ORDER`` in ``paperless.conf`` to any date order
-that is accepted by dateparser_. Doing so will cause ``paperless`` to default
-to any date format that is found in the title, instead of a date pulled from
-the document's text, without requiring the strict formatting of the document
-filename as described above.
-

-
-Transforming filenames for parsing
-==================================
-
-Some devices can't produce filenames that can be parsed by the default
-parser. By configuring the option ``PAPERLESS_FILENAME_PARSE_TRANSFORMS`` in
-``paperless.conf`` one can add transformations that are applied to the filename
-before it's parsed.
-
-The option contains a list of dictionaries of regular expressions (key:
-``pattern``) and replacements (key: ``repl``) in JSON format, which are
-applied in order by passing them to ``re.subn``. Transformation stops
-after the first match, so at most one transformation is applied. The general
-syntax is
-
-.. code:: python
-
-   [{"pattern":"pattern1", "repl":"repl1"}, {"pattern":"pattern2", "repl":"repl2"}, ..., {"pattern":"patternN", "repl":"replN"}]
-
-The example below is for a Brother ADS-2400N, a scanner that allows
-different names to different hardware buttons (useful for handling
-multiple entities in one instance), but insists on adding ``_<count>``
-to the filename.
-
-.. code:: python
-
-   # Brother profile configuration, support "Name_Date_Count" (the default
-   # setting) and "Name_Count" (use "Name" as tag and "Count" as title).
-   PAPERLESS_FILENAME_PARSE_TRANSFORMS=[{"pattern":"^([a-z]+)_(\\d{8})_(\\d{6})_([0-9]+)\\.", "repl":"\\2\\3Z - \\4 - \\1."}, {"pattern":"^([a-z]+)_([0-9]+)\\.", "repl":" - \\2 - \\1."}]

+paperless-ng 0.9.9
+##################
+
+Christmas release!
+
+* Bulk editing
+
+  * Paperless now supports bulk editing.
+  * The following operations are available: Add and remove correspondents, tags, document types from selected documents, as well as mass-deleting documents.
+  * We've got a more fancy UI in the works that makes these features more accessible, but that's not quite ready yet.
+
+* Searching
+
+  * Paperless now supports searching for similar documents ("More like this") both from the document detail page as well as from individual search results.
+  * A search score indicates how well a document matches the search query, or how similar a document is to a given reference document.
+
+* Other additions and changes
+
+  * Clarification in the UI that the fields "Match" and "Is insensitive" are not relevant for the Auto matching algorithm.
+  * New select interface for tags, types and correspondents allows filtering. This also improves tag selection. Thanks again to `Michael Shamoon`_!
+  * Page navigation controls for the document viewer, thanks to `Michael Shamoon`_.
+  * Layout changes to the small cards document list.
+  * The dashboard now displays the username (or full name if specified in the admin) on the dashboard.
+
+* Fixes
+
+  * An error that caused the document importer to crash was fixed.
+  * An issue with changes not being possible when ``PAPERLESS_COOKIE_PREFIX`` is used was fixed.
+  * The date selection filters now allow manual entry of dates.
+
+* Feature Removal
+
+  * Most of the guesswork features have been removed. Paperless no longer tries to extract correspondents and tags from file names.
