I am glad to announce the availability of Polylang 1.5.4. I continue to improve the API for a better interaction with themes and third party plugins and this release comes with 3 new functions: pll_get_post_language, pll_get_term_language and pll_translate_string.
The compatibility with Jetpack 3 has been improved by adapting the WPML specific code included in jetpack to Polylang. A conflict with WordPress SEO has been solved.
A few users have been annoyed with too restrictive permissions. This should now be fixed. And a couple of other bugs have been fixed too.
