Version 1.3.0 is available for download.

This update features a number of features targeted to improve performance when synchronizing photo metadata (Library > Plug-in Extras > Gallery Export Plugin Extras > Synchronize Metadata). However, in order to take advantage of these improvements you must install version 2 of the Lightroom Plugin Helper module in your Gallery hosting environment. The latest version of this module is available in the Download section on the Gallery Plugin's home page.

For a detailed list of changes and to download the update, see the Gallery Plug-in home page.
