We've released Bark 0.8.0. Restoring a wallet from its mnemonic now takes one scan of the Ark server: it asks for every VTXO under the wallet's xpub, so a restore works without the key gap limit or a backup, and one that took 210 seconds now takes 60. Barkd now ships with the bark-web wallet UI built in, and wallet apps get a movement id back from every send and offboard, so they can label the payment they just made. There are breaking changes too, so read the changelog before you upgrade. Full changelog:

Payjoin boards are now available in Bark and enable a wallet app to receive a Payjoin and board onto Ark in the same transaction, saving the user fees and time. The same trick can also be used to on-ramp onto a Cashu mint running Bark, no channel management required. It may also be the first example of Transaction Cut-Through bitcoin has seen, a 13-year-old idea from Greg Maxwell! More details on the blog:
