Changes: v2.3.1...v2.4.0

Fix visibility of comments box on Old YouTube

We accidentally introduced a regression in v2.3.0. On Old YouTube, part of the comments box would still be visible after hiding the comments. Thanks to @1natsu172 for the fix 🥇

See issue #16 for more info.

Changes: v2.2.2...v2.3.0

Fix detection of New YouTube home page

If detection fails on the homepage, we won't be able to inject the comments button when the user later navigates to a video.

Changes: v2.2.1...v2.2.2

Fix detection of New YouTube

The detection broke as New YouTube changed its DOM. This was causing the 'Show comments' button to not appear on New YouTube. Now we check for New YouTube by checking if it's a Polymer app.

Changes: v2.2.0...v2.2.1
