+Changelog
+=========
+
+1.3.0 (2017-01-27)
+------------------
+
+**API Changes**
+
+- Throw ``PriorityLoop`` when inserting or reprioritising a stream that
+  depends on itself.
+- Throw ``BadWeightError`` when creating or reprioritising a stream with a
+  weight that is not an integer between 1 and 256, inclusive.
+- Throw ``PseudoStreamError`` when trying to reprioritise, remove, block or
+  unblock stream 0.
+- Add a new ``PriorityError`` parent class for the exceptions that can be
+  thrown by priority.
+
+1.2.2 (2016-11-11)
+------------------
+
+**Bugfixes**
+
+- Allow ``insert_stream`` to be called with ``exclusive=True`` but no explicit
+  ``depends_on`` value.
+
+1.2.1 (2016-10-26)
+------------------
+
+**Bugfixes**
+
+- Allow insertion of streams that have parents in the idle or closed states.
+  This would previously raise a KeyError.
+
+1.2.0 (2016-08-04)
+------------------
+
+**Security Fixes**
+
+- CVE-2016-6580: All versions of this library prior to 1.2.0 are vulnerable to
+  a denial of service attack whereby a remote peer can cause a user to insert
+  an unbounded number of streams into the priority tree, eventually consuming
+  all available memory.
+
+  This version adds a ``TooManyStreamsError`` exception that is raised when
+  too many streams are inserted into the priority tree. It also adds a keyword
+  argument to the priority tree, ``maximum_streams``, which limits how many
+  streams may be inserted. By default, this number is set to 1000.
+  Implementations should strongly consider whether they can set this value
+  lower.
+
+1.1.1 (2016-05-28)
+------------------
+
+**Bugfixes**
+
+- 2.5x performance improvement by swapping from ``queue.PriorityQueue`` to
+  ``heapq``.
+
+1.1.0 (2016-01-08)
+------------------
+
+**API Changes**
+
+- Throw ``DuplicateStreamError`` when inserting a stream that is already in the
+  tree.
+- Throw ``MissingStreamError`` when reprioritising a stream that is not in the
+  tree.
+
+1.0.0 (2015-12-07)
+------------------
+
+- Initial release.
