 ### v4.2.0
 
+* Slightly improved popup design. (Design change suggested by PortaTrekos)
 * Player detection: youtube and twitch now have manual player element detection, with strictly defined players. 
-* Improved design (thanks, _INSERT CREDIT HERE_)
-* Improved enabling/disabling of embedded videos
+* Improved site settings control in extension popup. It's possible to enable extension for previously disabled embedded sites.
+* Improved incompatibilities with reddit, where videos would be vertically misaligned when not using RES
+* Fixed imcompatibilities with Iridium. Flicker when clicking play/pause or switching between big and popup player is caused by either Youtube or Iridium trying to apply their styles over mine.
+* Issues with inconsistent alignment that some people reported are potentially fixed

     <p>Full changelog for older versions <a href="https://github.com/xternal7/ultrawidify/blob/master/CHANGELOG.md">is available here</a>.</p>

+    <p class="label">4.2.0</p>
     <ul>
-      <li>Disabled extension on gfycat.</li>
-      <li>Fix for old.reddit.com applied to www.reddit.com</li>
+      <li>Slightly improved popup design. (Design change suggested by PortaTrekos)
+      <li>Improved site settings control in extension popup. It's possible to enable extension for previously disabled embedded sites.</li>

+      <li>Fixed imcompatibilities with Iridium. Flicker when clicking play/pause or switching between big and popup player is caused by either Youtube or Iridium trying to apply their styles over mine.</li>
+      <li>Youtube, reddit and twitch players are now determined by a query string (instead of less accurate automatic detection)</li>
+      <li>Some people reported issues with inconsistent video alignment on youtube. While I've not been able to make that bug happen to me,
+        (which means I haven't been able to fix it either), reports describe behaviour similar to what was going on with Iridium. Examining
+        the Iridium issue revealed an issue that could be potentially blamed for this behaviour. That issue was fixed. Since I've never been able to make this problem
+        happen to me, I'm not being able to verify whether that issue is gone. <b>If you're still experiencing issues with inconsistent video alignment,
+          please contact me via github, reddit or email.</b> See 'Report a problem' tab for more details.</li>

-          <li>Increased autodetection frequency from 0.6s to 0.3s. <b>This isn't likely to happen, but if you notice this
-             extension using excessive amounts of RAM (2+ GB), this is why. If you experience this issue, please contact me (see 'Report a problem' tab).</b>
