Version 3.4.2 is a second minor update for GD Rating System Pro 3.4, with very important updates to the Rich Snippets to match the changes Google has made to Rich Snippets specification last month.
Google is making changes to the Rich Snippets specification very often, and this time they have imposed a limit on the length of the Headline some snippets use (to 110 characters). Also, Image Objects are updated to require units with the image dimensions. So, the plugin now checks the length and cuts it to fit the allowed length, and it is also adding image dimensions with pixels unit specified.
The new version includes a lot of change to the translation strings used for the plural forms. The shared code library is also updated to the latest version.
For now, if you find any issues with the new version, please report them in the support forum.
