What happened
The official Shopify Merchant Changelog says the rollout began on September 15 and updates color, type, spacing, icons, and the surrounding frame across the Shopify admin.
Search, notifications, and the store picker have moved into the side navigation, which can collapse to create more room on the page.
Sidekick has moved from a side panel to a floating chat at the bottom of each page.
Shopify says the global rollout is gradual and will reach each admin automatically, with no setup required.

Why it matters
Merchants who rely on the previous navigation layout may need to adjust how they reach search, notifications, and store switching during the rollout.
The collapsible side navigation could make more workspace available, but the practical benefit will depend on how each team uses the admin.
Sidekick is intended to be available from more locations in the admin, which may change how merchants access it during routine work.
