We are working to release an update for WPML (and its add-ons plugins) to address some compatibility issues with WordPress 4.5.
WordPress 4.5 brings several changes in its API, changes which need to be addressed and which require holding the development of WPML 3.4 (more about WPML 3.4 in the next posts).
Of course, some bug fixes not related to WordPress 4.5 also slipped in, as they occurred during the development of WPML 3.4.
We are currently under full QA, which usually takes several days, but you can start using our beta version right now. If you do so, please share your feedback or questions in our support forum.
