Looks like JPEG XL is BACK ON THE MENU BAYBEE!!
Not really news I guess, you already have JXL in some form in current Firefox but YIPEE etc
EDIT: I have become the JPEG-XL joker. When I make the news, the https://jpegxl.info/ url will be in my manifesto.
Don’t worry, most everything on android (and presumably ios) doesn’t support JXL, and I keep having to explain to people what it even is. Much like with the mythical SA-CD before it, I fell for the meme format yet again. Your work media file uploading is safe.
