Heads Up
Information for users of Joomla! 3
Whilst official support for the Joomla 3 CMS will be removed when JCE v3.0 is released, the developer reports that minor updates addressing critical issues will continue to be provided for the 2.9.99 series using a supplemental version scheme, for example, 2.9.99.1, 2.9.99.2, etc.
This is to ensure Joomla 3 users remain supported for critical fixes while development progresses toward JCE v3.x.

JCE Developer recommends enabling IMagick PHP Extension
Reason: to improve performance when using the JCE Content Editor with images.
Read the developer's tutorial at the link below.
Quote:
"Image processing on your server is usually done by one of two PHP extensions - GD2 or IMagick. The latter is preferred, as it is more efficient, consumes less memory and is therefore better at processing large images. GD2 will always remove EXIF data from a resized image, regardless of the Remove EXIF Data option. You can check if IMagick is available on your site in System -> System Information -> PHP Information. Speak to your host if you do not see it listed." Source: JCE.
