What does client-side media processing mean for my site’s performance?

Client-side media processing shifts resizing and encoding tasks to the user’s browser before upload, reducing server CPU and memory use. This can speed up uploads, especially on shared or resource-constrained hosting, but may increase browser resource consumption during file handling.

Can I disable infinite scrolling in the Media Library?

Yes. WordPress 7.1 enables infinite scrolling by default but offers a per-user setting to restore traditional pagination, accommodating user preferences and workflows.

How does the new accessible tooltip API affect plugin development?

The accessible tooltip API provides a standardized way to add tooltips that are keyboard and screen reader friendly. Plugin developers should adopt this API to replace title attributes or custom tooltip implementations to improve accessibility compliance.

Will existing themes and plugins be compatible with Global Styles improvements?

Most themes and blocks using Core Global Styles will benefit automatically, but custom themes or plugins relying on fixed styles may need updates to leverage new responsive variants and pseudo states effectively.

Are there any breaking changes I should prepare for in WordPress 7.1?

Yes. Some APIs have changed, and new lifecycle hooks in the Abilities API may affect permission logic. Client-side media processing may alter how media uploads behave. Testing in staging environments before upgrading production sites is strongly advised.
