Notable changes:

Ada 2.0
Node.js v18.17.0 comes with the latest version of the URL parser, Ada. This
update brings significant performance improvements to URL parsing, including
enhancements to the url.domainToASCII and url.domainToUnicode functions
in node:url.

Ada 2.0 has been integrated into the Node.js codebase, ensuring that all
parts of the application can benefit from the improved performance. Additionally,
Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4,
while also eliminating the need for the ICU requirement for URL hostname parsing.

Web Crypto API
Web Crypto API functions' arguments are now coerced and validated as per
their WebIDL definitions like in other Web Crypto API implementations. This
further improves interoperability with other implementations of Web Crypto API.

Notable changes:

Ada 2.0
Node.js v18.17.0 comes with the latest version of the URL parser, Ada. This
update brings significant performance improvements to URL parsing, including
enhancements to the url.domainToASCII and url.domainToUnicode functions
in node:url.

Ada 2.0 has been integrated into the Node.js codebase, ensuring that all
parts of the application can benefit from the improved performance. Additionally,
Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4,
while also eliminating the need for the ICU requirement for URL hostname parsing.

Web Crypto API
Web Crypto API functions' arguments are now coerced and validated as per
their WebIDL definitions like in other Web Crypto API implementations. This
further improves interoperability with other implementations of Web Crypto API.
