WordPress has rolled out a security update to safeguard publishers from medium to high-level vulnerabilities. The 6.02 version of the security and vulnerability update will be part of most WordPress sites automatically and will influence the performance of each WordPress site. So, you must check if the security and maintenance update is already part of your website. The update will automatically be part of websites belonging to version 3.7.
Regarding bug fixes, the update comprises a dozen changes for the WordPress core alone and an additional 5 for the block editor. Amongst these, the major one is the amendment in the Pattern Directory that is supposed to aid theme authors. The new change will provide only patterns that align with the theme. The aim here is to make it attractive and improve the user experience for publishers.
