AbortSignal.any() is now available.
Updated V8 to 11.4.
Following an update to the WHATWG URL spec, the delete() and has() methods of the URLSearchParams class now accept an optional second argument to specify the search parameter’s value. This is potentially a breaking change, so it is gated behind the new urlsearchparams_delete_has_value_arg and url_standard compatibility flags.
Added the strict_compression_checks compatibility flag for additional DecompressionStream error checking.

A new Hibernatable WebSockets API (beta) has been added to Durable Objects. The Hibernatable WebSockets API allows a Durable Object that is not currently running an event handler (for example, processing a WebSocket message or alarm) to be removed from memory while keeping its WebSockets connected (“hibernation”). A Durable Object that hibernates will not incur billable Duration (GB-sec) charges.

The new connect() method allows you to connect to any TCP-speaking services directly from your Workers. To learn more about other protocols supported on the Workers platform, visit the new Protocols documentation.
We have added new native database integrations for popular serverless database providers, including Neon, PlanetScale, and Supabase. Native integrations automatically handle the process of creating a connection string and adding it as a Secret to your Worker.
You can now also connect directly to databases over TCP from a Worker, starting with PostgreSQL. Support for PostgreSQL is based on the popular pg driver, and allows you to connect to any PostgreSQL instance over TLS from a Worker directly.
The R2 Migrator (Super Slurper), which automates the process of migrating from existing object storage providers to R2, is now Generally Available.

The performance.now() and performance.timeOrigin APIs can now be used in Cloudflare Workers. Just like Date.now(), for security reasons time only advances after I/O.

The new nodeJsCompatModule type can be used with a Worker bundle to emulate a Node.js environment. Common Node.js globals such as process and Buffer will be present, and require('...') can be used to load Node.js built-ins without the node: specifier prefix.
Fixed an issue where websocket connections would be disconnected when updating workers. Now, only websockets connected to Durable Object instances are disconnected by updates to that Durable Object’s code.

Fixed a bug where transferring large request bodies to a Durable Object was unexpectedly slow.
