- Return Visitor block. Add the new Return Visitor block in the block editor and try various options. The visitor count is stored in as the cookie value for
jp-visit-counter. - Post Images: When requesting the post image (used by Related Posts and other functionality), try getting the image for non-post/page CPTs, like attachments. Image attachments should now return a thumbnail.
- Sitemaps: With a video hosting plan (e.g. Professional), upload videos and then review the video sitemap. Ensure thumbnails are displayed once VideoPress has processed the video.
- Ads block: There is now a toggle to hide on mobile devices. With a paid plan with ads enabled, add some blocks, hide some from mobile and give it a spin.
- All blocks: The block development and building process has moved from Calypso to the Jetpack repo. Add various Jetpack blocks to ensure no hiccups.
- If you have the opportunity to test in an older browser like IE11, please do so. You may catch some interesting bugs!
- At any point during your testing, remember to check your browser's JavaScript console and see if there are any errors reported by Jetpack there.
Thank you for all your help!
