NOTE: this is blocked until development and instrumentation of the collapsible sidebar & max-width is complete.
== Background
After building out our collapsible sidebar and fixed width for articles, we will be ready to make our first deployment to our test wikis. We will do this in two steps to allow for sufficient QA. To learn more about our release plan, please see our project page: https://www.mediawiki.org/wiki/Reading/Web/Desktop_Improvements/Opting_in_and_Release_Plan
== Acceptance criteria
Step 1:
[] Switch the default of the following wikis to the new version of the vector skin: euwiki, hewiki, ptwikiversity
Step 2:
[] Switch the default of the following wikis to the new version of the vector skin: frwiki, frwiktionary, fawiki
== Questions
- If we're changing anonymous presentation, what will we do about cached HTML? Do we have to purge the whole cache?
- Are there more changes planned that will significantly impact the HTML? For example, moving the search bar. Do the caching implications change the deployment strategy?
