## [2.9.0] - 2020-07-06

### Fixed

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

* Test coverage and CI for ARM (#518 by odidev).


## [2.8.0] - 2020-02-19

(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] - 2019-10-08

* Fixed potential error when creating a new appdata directory.


## [2.6.0] - 2019-10-07

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).

* 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] - 2019-02-06

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] - 2018-09-06

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

## [1.2.0] - 2015-02-23

Basically a hotfix release. But some new features were introduced.

* Fixed that pip-installing would put README.md and other files in sys.prefix.
* The used ffmpeg exe can be overridden with an environment variable
  'IMAGEIO_FFMPEG_EXE'.
* Relative paths work again.
* FFMPEG plugin moved to correct timeframe when seeking (thanks Zulko)


## [1.1.0] - 2015-02-04

Imageio is now a dependency of `Moviepy <https://github.com/Zulko/moviepy/>`_,
which exposed a few issues to fix. Imageio is now also available as a
Debian package (thanks Ghislain!). Furher, we tweaked our function names
to be cleared and more consistent (the old names still work).

* All ``Xsave()`` functions are renamed to ``Xwrite()``.
  Also ``read()`` and ``save()`` are now ``get_reader()`` and ``get_writer()``.
  The old names are available as aliases (and will be for the foreseable
  future) for backward compatibility.
* Protect user from bringing computer in swap-mode by doing e.g.
  ``mimread('hunger games.avi')``.
* Continuous integration for Windows via Appveyor.
* All imports are relative, so imageio can be used as a subpackage in
  a larger project.
* FFMPEG is the default plugin for reading video (since AVBIN has issues).
* Better handling on NaN and Inf when converting to uint8.
* Provide dist packages that include freeimage lib and a few example images.
* Several changes to ease building into Debian package.
* Fixed segfault when saving gif
  (thanks levskaya, https://github.com/imageio/imageio/pull/53).
* Don't fail when userdir is not writable.
* Gif plugin writer has fps param for consistency with avi/mp4 etc.


## [1.0.0] - 2014-11-13

In this release we did a lot of work to push imageio to a new level.
The code is now properly tested, and we have several more formats.

The big changes:

* Many unit tests were written to cover over 95% of the code base.
  (the core of imageio has 100% coverage).
* Setup continuous integration (CI) using Travis.
* Imageio now follows PEP8 style guides (and this is tested with CI).
* Refactoring of the code base. Resulting in a cleaner namespace.
* Many improvements to the documementation.

Plugins:

* The FFMPEG format is now well supported. Binaries are provided.
* New AVBIN format for more efficient reading of video files.
* New NPZ format that can store (a series of) arbitrarily shaped numpy arrays.
* New SWF format (shockwave flash) for lossless animated images.
* Improvements to the GIF format. The GIF and ANIGIF formats are now merged.

Further:

* New simple website to act as a front page (http://imageio.github.io).
* Compatibility with Pypy.
* We provide a range of :doc:`standard images <standardimages>` that are
  automatically downloaded.
* Binaries (libs and executables) that plugins of imageio uses are now
  downloaded at runtime, not at build/install time. This simplifies
  things a lot.
* freeimage plugin now fully functional on pypy
* Added utilities for developers (run ``python make`` from the repo root).
* PNG, JPEG, BMP,GIF and other plugins can now handle float data (pixel
  values are assumed to be between 0 and 1.
* Imageio now expand the user dir when filename start with '~/'.
* Many improvements and fixes overall.


## [0.5.1] - 2014-06-23

* DICOM reader closes file after reading pixel data
  (avoid too-many-open-files error)
* Support for video data (import and export) via ffmpeg
* Read images from usb camera via ffmpeg (experimental)


## [0.4.1] - 2013-10-26

* We moved to github!
* Raise error if URI could not be understood.
* Small improvement for better error reporting.
* FIxes in mvolread and DICOM plugin


## [0.4.0] - 2013-03-27

Some more thorough testing resulted in several fixes and improvements over
the last release.

* Fixes to reading of meta data in freeimage plugin which could
  cause errors when reading a file.
* Support for reading 4 bpp images.
* The color table for index images is now applied to yield an RGBA image.
* Basic support for Pypy.
* Better __repr__ for the Image class.


## [0.3.2] - date unknown

* Fix in dicom reader (RescaleSlope and RescaleIntercept were not found)
* Fixed that progress indicator made things slow


## [0.3.1] - date unknown

* Fix installation/distribution issue.


## [0.3.0] - date unknown

This was a long haul. Implemented several plugins for animation and
volumetric data to give an idea of what sort of API's work and which
do not.

* Refactored for more conventional package layout
  (but importing without installing still supported)
* Put Reader and Writer classes in the namespace of the format. This
  makes a format a unified whole, and gets rid of the
  _get_reader_class and _get_write_class methods (at the cost of
  some extra indentation).
* Refactored Reader and Writer classes to come up with a better API
  for both users as plugins.
* The Request class acts as a smart bridging object. Therefore all
  plugins can now read from a zipfile, http/ftp, and bytes. And they
  don't have to do a thing.
* Implemented specific BMP, JPEG, PNG, GIF, ICON formats.
* Implemented animated gif plugin (based on freeimage).
* Implemented standalone DICOM plugin.


## [0.2.3] - date unknown

* Fixed issue 2 (fail at instal, introduced when implementing freezing)


## [0.2.2] - date unknown

* Improved documentation.
* Worked on distribution.
* Freezing should work now.


## [0.2.1] - date unknown

* Wrote a lot of documentation.
* Added example (dummy) plugin.


## [0.2.0] - date unknown

* New plugin system implemented after discussions in group.
* Access to format information.


## [0.1.0] - date unknown

* First version with a preliminary plugin system.
