If you are still relying on AES-128-GCM or SHA-256 for integrity checks, Beta 2 will refuse to negotiate. The minimum bar is now with SHA-384 for HMAC. Additionally, the "Compatibility Mode" (which allowed fallback to classical elliptic curve P-384) has been entirely removed. This is a breaking change. Any peer running Exo 4.6 or earlier will fail to establish a session unless upgraded.
: A unique feature of this beta is the ability to choose which applications to install before the system even initializes for the first time, allowing for a cleaner setup. Known Issues in Beta 2 Darkmatter Exo 4.7 Beta 2
: It is noted for being one of the most customizable versions of the now-discontinued Phoenix OS project. Installation and Availability If you are still relying on AES-128-GCM or
In the center of the testing floor, a shadow began to pull itself out of Kaelen’s back. It was a perfect silhouette of the Exo-suit, but it moved with a predatory, fluid grace that Kaelen wasn't inputting. The "Beta 2" wasn't just stabilizing the pilot; it was accidentally manifesting the pilot's subconscious fears as a physical, dark-matter entity. "Aborting!" Elias screamed. This is a breaking change
The biggest change under the hood is the swap from CRYSTALS-Kyber to . Why? Kyber relies on Module-LWE (Learning with Errors), which, while efficient, has a smaller security margin against side-channel attacks when implemented in software. FrodoKEM is based on standard LWE, which is mathematically “cleaner” and avoids the complicated structure that some researchers fear could be exploited by a future quantum algorithm.
