PNGv4/v5 may improve compression but it won’t be backwards compatible. It’ll get stuck in the same kind of limbo JPEG-XL is. Until that gets resolved, we’ll have to stick with AVIF/HEIFF/WebP.
I don’t really see the need for advanced compression in lossless files. You generally don’t download those in bulk without looking at lower quality previews anyway. Would be nice if the real file supports the same colour space the preview file does anyway. I’ll appreciate it when it lands, but I don’t think I’ll spend the hours converting my photo library to save maybe half a gigabyte of space.
The 6GHz band was used before it was used for WiFi. Frequencies can be reassigned, and they get reassigned on a regular basis.
It’s a pretty stupid thing to do that has no use other than annoying random people, but it the WiFi equipment industry can’t deal with changes like these, they need to get their act together. Samsung and Comcast will be fine, and grandma just needs to install her updates like she should be doing anyway.
