Has WordPress 4.2.1 Changed Embedded Video Heights ?

Can anyone tell me whether-or-not the recent upgrade to WordPress 4.2 has changed the way that embedded video heights are automatically set?

I thought I saw some Timeline tickets on this subject, but can’t remember where to find them. I’m using this plugin https://ww.wp.xz.cn/plugins/advanced-responsive-video-embedder/ that doesn’t seem to work the way that it used to since the WordPress Upgrade.
