NextGEN Gallery Optimizer Now Discontinued
Due to the major breaking changes set to be introduced with the Gutenberg editor in WordPress v5.0, NextGEN Gallery Optimizer has now been discontinued.
Valid license holders for Optimizer Pro will continue to receive support if required, but the product has now been removed from sale, in preparation for the release.
I want to say a big thank you to everyone who's enjoyed using the plugin to optimize their sites over the last six and a half years, and wish you all the best for the future.
Kind regards,
Mark.
NextGEN Gallery Optimizer Documentation
Compatibility
Compatibility and requirements
This section details Optimizer Pro's current compatibility and software requirements.
NextGEN Gallery compatibility
NextGEN Gallery Optimizer v1.0 to v1.1.2 was written for the original (now Legacy) NextGEN codebase v1.6.2 to v1.9.13.
As of Optimizer v2.0, the plugin is also now fully compatible with the new NextGEN v2 codebase (v2.0.0 to v2.1.60), the original NextGEN Legacy codebase (v1.6.2 to v1.9.13), as well as the NextGEN Legacy fork called NextCellent Gallery (v1.9.14 to v1.9.31).
WordPress compatibility
NextGEN Gallery Optimizer is compatible with all versions of WordPress from v3.7 to the latest v4.7.
PHP requirements
As of version 2.0, Optimizer now requires PHP 5. This is the same as WordPress itself since v3.2, which was released in July 2011.
This shouldn't cause any issues as according to the stats, it appears no current WordPress installs are using anything less than PHP 5.1.
Is Optimizer compatible with WordPress Multisite?
Not at the moment, however we are looking to add support for multisite installs in a future release of the plugin.
