The update drops support for Internet Explorer 10 and legacy browsers, adopts ES modules, and reduces library size by over 3kb. Breaking changes include removal of APIs with native browser equivalents, alignment with W3C focus/blur event specifications, and support for Trusted Types to prevent cross-site scripting attacks. Despite being used by 70.9% of all websites, some developers question jQuery's relevance for modern web development, citing improved browser compatibility and native JavaScript capabilities. However, others appreciate its concise API and ease of use. ## Full article daily.dev links to this article rather than hosting it.
