We just pushed the official update for WPML 3.2.3. This version includes all necessary updates for WordPress 4.3, as well as a number of other improvements.
This update should appear in your WordPress dashboard in a few hours (depending on the WordPress updates cache). Please be sure to update WPML before you update WordPress to 4.3.
The easiest way to update WPML is by registering it and letting the automatic update to its magic. You can always update manually by downloading the recent ZIP files from your wpml.org account.
Experience tells us that things can go wrong. This update of WordPress introduces several API changes (nothing like the huge API change in WordPress 4.2.3). These changes may effect your theme and plugins. We recommend that you make full backup of your site before the update and carefully test functionality after.
The full list of features is listed in the WPML 3.2.3 RC. There’s also an important technical note about translation for widget titles.
