WordPress 5.7 has been released! Along with more editor improvements and a far more accessible admin color scheme, this release also includes a far simpler flow for moving from HTTP to HTTPS and improves overall performance by introducing lazy load for most iframe embeds. For specifics, check out the changelog.
