Reading/Web/Release timeline/Visual Changes

This page is a companion page to the Release timeline, which documents visual changes (both expected and unexpected) that went out in each release as caught by https://pixel.wmcloud.org/. If a release has no heading, this means there were no visual changes in that release. We began tracking visual changes for the wmf10 branch (comparing master against wmf.9).

** Need further investigation
 * Test group: Login - 2 failures. Cause: Flakiness. **

 * Echo - 6 failures - Cause: https://phabricator.wikimedia.org/T342907
 * Desktop - 1 failures - Cause: Flakiness
 * Mobile - 67 failures - Cause: https://phabricator.wikimedia.org/T342908 Mostly icon related (alignment/size). Issues of concern relating to default editor will hopefully be fixed in next run. **
 * Desktop-dev - 2 failures - Cause: Nothing important.

Last updated: 23 May 2022

Desktop has 14 failures. 8 of these are on the history page and report the reference images having no revision history but those are false positives and is a result of a database schema change that occurred this week and that affected the revision table (Pixel should be more resilient to DB schema changes in the future).

Mobile (5 failed/15 pass): The notification and search icons will show a small shift due to https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Echo/+/793114. This is expected. The settings link was restored to the main menu (https://phabricator.wikimedia.org/T307696) leading to more expected failures in minerva_mobile_mainmenu-open.

All desktop tests are passing.

Mobile (7 failed/13 pass): Mobile tests were introduced but are flaky due to the sidebar animation and layout shift involving the footer logo. The latter should be resolved in.

Comparing master against origin/wmf/1.39.0-wmf.10
Last updated: 6th May 2022

22 passed | 38 failed (36% pass)

The failures here were due to expected changes:


 * [Expected] Fix spacing/margins for screens between 1000 and 1200 px
 * [Expected] Previously the height between the page title and the content was different on special pages vs regular pages. This was corrected in 789207
 * [Expected] The introduction of the toolbar component in 787562 led to slight pixel misalignment in the article namespace and action tabs. This was expected preparation for the introduction of a grid system to Vector and moving the article tools below the title.

 * 1) [Expected] We’re collapsing things into the more menu at lower breakpoints to make things more predictable. As a result edit icon will be hidden under more menu at lower resolutions now. There was one unexpected bug associated with this on history and Special:RecentChanges which will be fixed by 787801 so that this issue didn't got out with the release.
 * 2) [Expected] We changed the alignment of logo with table of contents and search with tabs
 * 3) [Regression]  Main menu placement is off on screens 700-1000px
