Release Notes: The imagick extension was written from scratch. There are a lot of new functions, and some old functions do not work anymore.
Release Notes: imagick_sample(), imagick_resize(), imagick_crop(), imagick_shear(), imagick_rotate(), and imagick_morph() are now deprecated and have been replaced by the corresponding imagick_copy_* functions, which return a new handle. The deprecated functions will be removed in the next version. Some critical resource allocation errors were also fixed.
Release Notes: A rather annoying segfault with imagick_read was fixed and some more code cleanups were added.
Release Notes: Better config support and error handling, support for PHP versions lower than 4.1, and a new annotate text function were added.
