Recent Bark releases 0.1.4, 0.2.0, and 0.2.1 have been packed with updates. The highlights: Slim VTXO storage cuts wallet memory use 20–100x, real-time notifications replace polling so wallets update the instant something happens, and a single payment request now bundles Ark, Lightning, and on-chain into one QR. And to ensure Bark slots nicely into existing stacks, emergency exits and boarding can now both be driven by an external on-chain wallet with its own signer.
