1.30.0 - Make the WordPress system emails look like they came from your site
WordPress sends its password resets and account notices as plain text that could have come from any site on the internet. 1.30.0 adds the option to send them as HTML carrying the site's own logo, colour and fonts, with a new Appearance > Email Branding screen to switch it on and rewrite what the four most visible ones say. It ships off — updating changes nothing an account holder receives until a site opts in. The Login Screen customiser moves to Appearance beside it, and both now inherit the block theme's main colour when no colour is set.
