Yoast Video SEO Premium 15.0

Added inLanguage property to the VideoObject schema piece.

Fixes a bug where YouTube videos would not be recognized, which meant that they wouldn’t be included in the XML Video Sitemap and the video settings in the metabox wouldn’t be available. You can re-index your YouTube videos with the Re-Index Videos button in the Video SEO options.

Bugfixes:

• Fixes a bug where the `yavs:upload_date` meta tag would output an incorrect time.
• Fixes a bug where incorrect video metadata would be saved on multisite environments in combination with MultilingualPress.
