# Atmos 0.4.0

> UDP proxying, new browser cores, connection controls, profile recovery, and interface updates

## Browser engine and antidetect

* Added browser cores 148, 149, 150, and 151.
* Added UDP proxying for WebRTC, QUIC, and HTTP/3.
* UDP traffic is blocked when it cannot be sent through the profile proxy, preventing direct UDP connections from exposing the real IP address.
* Added full CPU downscaling and upscaling on all platforms.
* Improved Chrome identity consistency and compatibility with modern browser fingerprint checks, including fingerprint.com scenarios.

## Browser profiles

* Added global startup tab controls with **New**, **Session**, and **List** modes.
* Added a trash flow for deleted browser profiles so profiles can be restored before permanent deletion.
* Added dedicated **Global settings** and **Extensions** sections under Browser.
* Fixed an issue where extensions could open multiple new windows during browser launch.

## Application connection

* Added **Settings → Connection** for routing Oxygen API, Wallet RPC, portfolio, and CEX requests through system or custom proxies.
* Browser profiles continue to use the proxy saved in each profile.

## Resources and interface

* Moved Tags and RPC management to **Resources** in the sidebar.
* Updated the RPC screen with network grouping, response status, latency, and endpoint action menus.
* Added an application data reset option to the locked vault screen for cases where the master password cannot be recovered.
* Added other visual improvements, browser fixes, and stability updates.
