2.9.0

Fixed

* More robust loading of  FEI SEM data (529 by jon-lab).
* Fix webcam not working on Win10 (525).

Added

* Add a few standard images useful to 3D visualization.
* The timeout used in HTTP requests can now be set with an environment variable (534 by Johann Neuhauser).
* The DICOM plugin can now used gdcm for compressed transfer formats.
* Better support for itk/sitk plugins (530 by Jonathan Daniel).
* Test coverage and CI for ARM (518 by odidev).

2.8.0

(skipping version 2.7 to avoid confusion with Python v2.7.)

Mentioning here for completeness: imageio-ffmpeg 0.4.0 was also recently
released, which fixes several (stability) issues for video io.

Fixed

* Better support for reading from http (some formats needed seek, we now deal with that).
* Make `Reader.__len__` work again when length is inf (stream/unknown).
* Set `-framerate` input param for ffmpeg when using webcam, fixing webcam support on macOS.
* Fix for handling TIFF predictor value of 1 (NONE) (by Milos Komarcevic).
* Fix false-positive zip detection (by Vsevolod Poletaev).
* Fix SPE filesize check for SPE v3 (by Antony Lee).
* Fix that SPE plugin failed on spe3 files with dtype uint32 (by Michael Schneider).
* Fix deprecation warning for numpy.

Added

* Expose SPE3 xml footer (by Antony Lee).
* Expose TIFF predictor tag for reading and writing (by Milos Komarcevic).
* Improve error message regarding modes.

Removed

* Drop support for Python 2.7 and Python 3.4.
* Drop support for AVbin, use ffmpeg instead.

2.6.1

* Fixed potential error when creating a new appdata directory.

2.6.0

This will likely be the last release to support Python 2.7.

Fixed:

* Fixed a security vulnerability for Windows users that have dcmtk installed,
and where an attacker can set the filename.
* Fixed bug in ``image_as_uint`` (451 by clintg6).
* Fix that only one webcam could be used when two cameras are connected that have the same name.
* Prevent paletted image with transparency to be converted to grayscale.

Added:

* Optimise 16-bit PNG write performance for newer versions of Pillow (440 by Ariel Ladegaard).
* More flexible setting of memory limit in ``mimread`` and ``mvolread`` (442 by Chris Barnes).
* Support for ASCII PNM files (447 by Tobias Baumann).
* Improved support for JPEG2000 (can now provide parameters) (456 by Pawel Korus).
* Added support for compressed FITS images (458 by Joe Singleton).
* Improve imageio import time by avoiding pkg_resources import (462 by Mark Harfouche).
* Added example for compressing GIFs using pygifsicle (481 by Luca Cappelletti).

2.5.0

The ffmpeg plugin has been refactored:

* The core has been moved to a new library: imageio-ffmpeg.
* That library provides platform-specific wheels that includes ffmpeg,
so just ``pip install imageio-ffmpeg`` instead of the download step.
* Note that this new library is py3k only.
* Termination of ffmpeg subprocess is now more reliable.
* The reader of the ffmpeg plugin now always reports ``inf`` as the number of
frames. Use ``reader.count_frames()`` to get the actual number, or estimate
it from the fps and duration in the meta data.
* Removed ``CannotReadFrameError``.

Other changes:

* The avbin plugin has been depreacted and will be removed in a future version.
* Imnproved speed for PIL and FFMPEG plugsins by avoiding memory copies.
* Update the included tiffile library.
* Support for SimpleITK.
* Speed up tiffile plugin when writing to something else than a filename.
* Fix that writing to a file object would not work for some plugins.
* Can now pass image data to the write functions as anything that resolves to
a numpy array with a numeric dtype.
* One can now read from a memoryview.
* Fix error related to paletted BMP with the Pillow plugin.
* Improved logging.

2.4.1

* Fix installation issue on flavors of Ubuntu 14.04 /w Python 2.7  (378).
* Use `np.frombuffer` instead of `np.fromstring` in some cases.

2.4.0

* Renamed ``Image`` class to ``Array`` and add documentation for this ndarray subclass.
* Reading from HTTP and zipfiles has been improved and better documented.
* Improvements to reading and writing of Tiff metadata (by Lukas Schrangl).
* Better dealing of tifffile dependencies on Python 2.7 (330 and 337 by Chris Barnes).
* Reader for the SPE format (358 by lschr).
* Better termination of FFMPEG when reading from webcam (346 by Dennis Vang).
* FFMPEG support for reading 16bit videos (342 by Peter Minin).
