• When entering a URL without specifying a scheme in the browser's address bar, now it tries to open it via HTTPS protocol, and if it fails, it will fall back to HTTP (previously, URLs without a scheme would open directly via HTTP). This does not affect non-public domains (for example, in a local network).
• In Linux, Windows 11, and Android 10+, HTTPS DNS records are now resolved by the operating system. Thus, if the user has enabled DNS-over-HTTPS support in the operating system, there is no need to enable DoH additionally in the browser. Moreover, this allows the use of HTTP/3 without the header Alt-Svc and automatically upgrade HTTP requests to HTTPS if an HTTPS DNS record is present. Importantly, this also works with support for Encrypted Client Hello (ECH).

All this is useful for data exchange with the graphics processor in cases where precision must be sacrificed for memory savings.
  • Regular expressions can now use the same name for named capture groups in different disjunction variants. Support for the deprecated event.
• API:
  • Enabled textInput (allows web applications that use deprecated libraries or platforms relying on these events to function). Modern applications should use beforeinput Support for the .toJSON() methods.
