-## ALPHA TESTERS WANTED: `multi-backend-refactor` AMD GPU + Intel CPU/GPU specific BNB backend implementations
+## `𝗯𝗶𝘁𝘀𝗮𝗻𝗱𝗯𝘆𝘁𝗲𝘀` 𝗺𝘂𝗹𝘁𝗶-𝗯𝗮𝗰𝗸𝗲𝗻𝗱 𝙖𝙡𝙥𝙝𝙖 𝗿𝗲𝗹𝗲𝗮𝘀𝗲 is out!
 
-We're in the process of a complex refactor in order to allow the support of additional hardware backends, other than CUDA, in BNB. The efforts around this are already quite far along and there's plenty of functionality already in place that is in need for users to take a hands-on approach! Mac support will likely soon also see progress. However, I recommend waiting 2 weeks until the device abstraction has further consolidated (**breaking changes upcoming**).
+🚀 Big news! After months of hard work and incredible community contributions, we're thrilled to announce the 𝗯𝗶𝘁𝘀𝗮𝗻𝗱𝗯𝘆𝘁𝗲𝘀 𝗺𝘂𝗹𝘁𝗶-𝗯𝗮𝗰𝗸𝗲𝗻𝗱 𝙖𝙡𝙥𝙝𝙖 𝗿𝗲𝗹𝗲𝗮𝘀𝗲! 💥
 
-Currently, you still need to compile from source, after checking out the `multi-backend-refactor` branch (instructions WIP, but [the current docs on the compilation from source](https://huggingface.co/docs/bitsandbytes/main/en/installation#compile-from-source) are a good starting point; [feel free to share tips / input in this Github discussion](https://github.com/TimDettmers/bitsandbytes/discussions/1219). We'll soon enable nightly releases to make this much easier for you!
