The WordPress core development team builds WordPress! Follow this site for general updates, status reports, and the occasional code debate. There’s lots of ways to contribute:
Included in WordPress 4.9.6 are several new functions and tools that you should be aware of. Here is a brief breakdown of resources to help you become acquainted with WordPress 4.9.6.
Attention: Theme Authors
4.9.6 adds several new privacy related features, one of which may require a small styling adjustment. These are detailed in the following dev note.
WordPress 4.9.6 introduces some new tools related to data privacy. This includes a tool for users to request an export of all the stored data associated with them on the site. It also includes a tool for users to request erasure of that same data. Both tools include admin workflows to fulfill those requests.
To help plugin and theme authors integrate with these new tools, several new pages in the Handbook have been created.
To help WordPress Core, plugins, and themes with forward compatibility, a polyfill for each of these functions has been added in 4.9.6. When a site is not running a version of PHP that includes these functions, WordPress will automatically load these polyfills.
