+- OpenSubtitles: detect and match video/subtitle FPS (framerate) to reduce out of sync subtitle matches
+- core: internal fixes; add _markerlib library (rare)

+
+
+1.3.19.379
+- core: new recent items implementation (used in "Items with missing subtitles"), now really picking up everything instead of using Plex's recently_added API endpoint
+- core: be more strict about title matching - a matched title doesn't automatically mean season and episode are correct, too
+- core: rewrote the hash matching algorithm to not blindly trust hash matches anymore, but instead episodes have to match the series name, season number, episode number and format (BluRay, HDTV...); movie have to at least match the title, format and codec for the hash to be considered
+- core: remove TheSubDB support for now, as it only supports hash-based matching
+- scheduler: more robust item-fail-handling (fixes #81)

+- config: make logging verbosity configurable, default: WARNING - log files should be considerably smaller now
+- config: make console logging optional, default: off - good for development/debugging

+- menu: show the current and past state of the important menu actions such as (force)-refresh an item or refreshing the menu, on the Refresh-button's description
+- plugin now isn't in the dev mode by default and has logging to the console off (in certain configurations this resulted in huge syslogs)
+
+
+1.3.6.316
+- scheduler: missing subtitles task now able to handle huge libraries (thanks @chopeta, @comrade)
+- scheduler: detect item-stalling, add wait and retry logic to make missing subtitles task more robust
+- scheduler: report failed items to logs after task run completion
+- hint series name and episode title, or movie title to guessit to make detection way better (e.g. for Mr. Robot)
+
+1.3.6.304
+- scheduler: correct the recent-determination of the search for missing subtitles in recently_added task
+- scheduler: rewrote search for missing subtitles task; it now requests refreshes one by one and not in bulk anymore (hopefully fixes stalling)
+- handle rare cases of weird file system encodings (ANSI_X3.4-1968 for example)
+- fix simplejson warning on startup
+
+1.3.6.297
+- rename Sub-Zero to Sub-Zero.bundle (requirement for adding Sub-Zero to the Plex channel directory)

+"""Generic interface to all dbm clones.

+
+The returned object is a dbhash, gdbm, dbm or dumbdbm object,
+dependent on the type of database being opened (determined by whichdb
+module) in the case of an existing dbm. If the dbm does not exist and
+the create or new flag ('c' or 'n') was specified, the dbm type will
+be determined by the availability of the modules (tested in the above
+order).
+
+It has the following interface (key and data are strings):
+
+        d[key] = data   # store data at key (may override data at
+                        # existing key)
+        data = d[key]   # retrieve data at key (raise KeyError if no

+        del d[key]      # delete data stored at key (raises KeyError
+                        # if no such key)
+        flag = key in d   # true if the key exists
+        list = d.keys() # return a list of all existing keys (slow!)

+        Vista:      C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Logs

+    value for Windows and appends "log" to the user cache dir for Unix.

+
+* Fixed a bug that deranged the tree when part of it was

+
+* Fixed a parse bug with the html5lib tree-builder. Thanks to Roel

+= 4.4.0 (20150703) =
+
+Especially important changes:
+
+* Added a warning when you instantiate a BeautifulSoup object without
+  explicitly naming a parser. [bug=1398866]
+
+* __repr__ now returns an ASCII bytestring in Python 2, and a Unicode
+  string in Python 3, instead of a UTF8-encoded bytestring in both
+  versions. In Python 3, __str__ now returns a Unicode string instead
+  of a bytestring. [bug=1420131]
+
+* The `text` argument to the find_* methods is now called `string`,
+  which is more accurate. `text` still works, but `string` is the
+  argument described in the documentation. `text` may eventually
+  change its meaning, but not for a very long time. [bug=1366856]
+
+* Changed the way soup objects work under copy.copy(). Copying a
+  NavigableString or a Tag will give you a new NavigableString that's
+  equal to the old one but not connected to the parse tree. Patch by
+  Martijn Peters. [bug=1307490]
+
+* Started using a standard MIT license. [bug=1294662]
+
+* Added a Chinese translation of the documentation by Delong .w.
+
+New features:
+
+* Introduced the select_one() method, which uses a CSS selector but
+  only returns the first match, instead of a list of
+  matches. [bug=1349367]
+
+* You can now create a Tag object without specifying a
+  TreeBuilder. Patch by Martijn Pieters. [bug=1307471]
+
+* You can now create a NavigableString or a subclass just by invoking
+  the constructor. [bug=1294315]
+
+* Added an `exclude_encodings` argument to UnicodeDammit and to the
+  Beautiful Soup constructor, which lets you prohibit the detection of
+  an encoding that you know is wrong. [bug=1469408]
+
+* The select() method now supports selector grouping. Patch by
+  Francisco Canas [bug=1191917]
+
+Bug fixes:
+
+* Fixed yet another problem that caused the html5lib tree builder to
+  create a disconnected parse tree. [bug=1237763]
+
+* Force object_was_parsed() to keep the tree intact even when an element
+  from later in the document is moved into place. [bug=1430633]
+
+* Fixed yet another bug that caused a disconnected tree when html5lib
+  copied an element from one part of the tree to another. [bug=1270611]
+
+* Fixed a bug where Element.extract() could create an infinite loop in
+  the remaining tree.
+
+* The select() method can now find tags whose names contain
+  dashes. Patch by Francisco Canas. [bug=1276211]
+
+* The select() method can now find tags with attributes whose names
+  contain dashes. Patch by Marek Kapolka. [bug=1304007]
+
+* Improved the lxml tree builder's handling of processing
+  instructions. [bug=1294645]
+
+* Restored the helpful syntax error that happens when you try to
+  import the Python 2 edition of Beautiful Soup under Python
+  3. [bug=1213387]
+
+* In Python 3.4 and above, set the new convert_charrefs argument to
+  the html.parser constructor to avoid a warning and future
+  failures. Patch by Stefano Revera. [bug=1375721]
+
+* The warning when you pass in a filename or URL as markup will now be
+  displayed correctly even if the filename or URL is a Unicode
+  string. [bug=1268888]
+
+* If the initial <html> tag contains a CDATA list attribute such as
+  'class', the html5lib tree builder will now turn its value into a
+  list, as it would with any other tag. [bug=1296481]
+
+* Fixed an import error in Python 3.5 caused by the removal of the
+  HTMLParseError class. [bug=1420063]
+
+* Improved docstring for encode_contents() and
+  decode_contents(). [bug=1441543]
+
+* Fixed a crash in Unicode, Dammit's encoding detector when the name
+  of the encoding itself contained invalid bytes. [bug=1360913]
+
+* Improved the exception raised when you call .unwrap() or
+  .replace_with() on an element that's not attached to a tree.
+
+* Raise a NotImplementedError whenever an unsupported CSS pseudoclass
+  is used in select(). Previously some cases did not result in a
+  NotImplementedError.
+
+* It's now possible to pickle a BeautifulSoup object no matter which
+  tree builder was used to create it. However, the only tree builder
+  that survives the pickling process is the HTMLParserTreeBuilder
+  ('html.parser'). If you unpickle a BeautifulSoup object created with
+  some other tree builder, soup.builder will be None. [bug=1231545]

+More of the jQuery API: nextUntil?
+
+Optimizations
+-------------
+
+The html5lib tree builder doesn't use the standard tree-building API,
+which worries me and has resulted in a number of bugs.
+
+markup_attr_map can be optimized since it's always a map now.
+
+Upon encountering UTF-16LE data or some other uncommon serialization
+of Unicode, UnicodeDammit will convert the data to Unicode, then
+encode it at UTF-8. This is wasteful because it will just get decoded
+back to Unicode.

+CDATA
+-----
+
+The elementtree XMLParser has a strip_cdata argument that, when set to
+False, should allow Beautiful Soup to preserve CDATA sections instead
+of treating them as text. Except it doesn't. (This argument is also
+present for HTMLParser, and also does nothing there.)
+
+Currently, htm5lib converts CDATA sections into comments. An
+as-yet-unreleased version of html5lib changes the parser's handling of
+CDATA sections to allow CDATA sections in tags like <svg> and
+<math>. The HTML5TreeBuilder will need to be updated to create CData
+objects instead of Comment objects in this situation.

+    a simple API that does not come with too much magic and is composable.
+
+    In case optparse ever gets removed from the stdlib, it will be shipped by
