List is updated with two new open source devices, Passport Prime and Jade Plus.
Passport Prime is not only a hardware wallet since it has many additional features, but I still decided to include it and wait to see the official release.
Jade Plus is already released and shipping started, this is upgraded slightly larger version of Jade wallet with some improvements and stronger materials.
Here is one size comparison between Jade and Jade Plus devices, you can clearly see significantly larger screen on Jae Plus:

I found this new version of Jade beautiful, I haven't seen anything about it yet, I simply found out about the new version when visiting the website
The Bitcoin Hole which does a great job by the way in listing all the features of all HWs making our choice easier.
Isn't Jade a bitcoin-only wallet?
I don't quite understand the question. Nothing in the post you quoted suggests otherwise. Both Passport and Blockstream manufacture bitcoin-only signing devices or airgapped hardware wallets if you like. They only offer support for Bitcoin, but the Passport Prime also offers ways to secure codes, keys, seed phrases, and other digital files that you may find important. That can include keys to altcoins.
Passport Prime is a great update, they said there will be third party app capabilities on KeyOS (which is a much better OS than Ledger's bolos) and it will have its first third party integration through a partnership with Cake Wallet, I'm curious to see what other open source third party apps will look like. There's no documentation yet other than a promotional video for Passport Prime.
