Get One Channel From Image
==========================
New method :py:meth:`PIL.Image.Image.getchannel` added.
New method :py:meth:`PIL.Image.Image.getchannel` is added.
It returns single channel by index or name. For example,
``image.getchannel("A")`` will return alpha channel as separate image.
``getchannel`` should work up to 6 times faster than ``image.split()[0]``
in previous Pillow versions.
Box Blur
========
New filter :py:class:`PIL.ImageFilter.BoxBlur` is added.
Partial Resampling
==================
@ -40,6 +46,22 @@ This release contains several performance improvements:
using a recent version of libjpeg-turbo.
TIFF Metadata Changes
=====================
* TIFF tags with unknown type/quantity now default to being bare
values if they are 1 element, where previously they would be a
single element tuple. This is only with the new api, not the legacy
api. This normalizes the handling of fields, so that the metadata
with inferred or image specified counts are handled the same as
metadata with count specified in the TIFF spec.
* The ``PhotoshopInfo``, ``XMP``, and ``JPEGTables`` tags now have a
defined type (bytes) and a count of 1.
* The ``ImageJMetaDataByteCounts`` tag now has an arbitrary number of
items, as there can be multiple items, one for UTF-8, and one for
UTF-16.
Core Image API Changes
