v2.0.1

Bug fix

• Fixes a regression in 2.0.0 that could cause an infinite loop under specific circumstances (see #52).

v2.0.0

New features

• PHP 8 compatibility (see #48 and #50, thank @Agapanthus).
• Add support for reading WebP images (see #45, thank @mreiden).
• Add support for multiple output color formats (RGB, hexadecimal, integer, array or instances of ColorThief\Color class).
• Add support for image adapter selection. You can now choose which image extension to use between GD, Imagick or Gmagick, or provide a custom image adapter.

Bug fix

• Fix bug where getPalette() does not always return the requested amount of colors (see #5).

Breaking changes

• Drop support for PHP 5.x, 7.0 and 7.1, now require 7.2+.
• Reworked exceptions so that all exceptions now inherit from ColorThief\Exception\Exception. Migrating from 1.x may require tweaking exception handling in calling code to avoid unhandled exceptions or preserve error handling logic. See 1bf90f4 for details.

Noticeable changes

• Switch to MIT license.
• Fileinfo extension is now required.
• Reworked some internal image loading logic.

v1.4.1

• Significant performance improvement. Around 30% faster and between 20 to 50% less memory usage (see #44, thank @mreiden).
• Fix incorrect palette with single color images (see #41, thank @mreiden).

v1.4.0

• Drop support for PHP 5.3, now require 5.4+.
• Fix incorrect palette with CMYK images using Imagick or Gmagick (see #37, thank @crishoj).

• Fix invalid color values under certain circumstances (see #24).
• Use a PSR-4 autoloader (see #28, thank @jbboehr).
• Test against PHP 7.1 (see #27, thank @jbboehr).
