v1.16.0

This release introduces support for the QUERY HTTP method and a new `ECONNREFUSED` error constant, along with significant bug fixes for HTTP, fetch, and XHR adapters related to redirects, aborts, headers, and timeouts.

affected

Users relying on `maxBodyLength` and `maxContentLength` in the fetch adapter, or those using percent-encoded credentials in URLs, will be affected.

action

Review the changes related to `maxBodyLength`, `maxContentLength`, and URL-decoded credentials before upgrading.

release_signals
-Fetch adapter now enforces `maxBodyLength` and `maxContentLength`, which were previously ignored.
-Basic auth credentials embedded in URLs are now URL-decoded, changing the behavior for percent-encoded credentials.
-`parseProtocol` now strictly requires a colon in the protocol separator, potentially breaking loose protocol parsing.
!Fetch adapter now enforces `maxBodyLength` and `maxContentLength`, providing better protection against DoS attacks and accidental large uploads.
!Deprecated `unescape()` replaced with modern UTF-8 encoding, affecting non-ASCII URL handling.
+Added support for the QUERY HTTP method across adapters and type definitions.
+Exposed `ECONNREFUSED` as a constant on `AxiosError` for easier error handling.
+Exported the internal `encode` helper from `buildURL` for reuse in userland param serializers.
