Minibits v0.0.6-alpha introduced the Minimum Viable Product (MVP) of the feature allowing users to receive tokens even when their device is offline, meaning that users can redeem the coins once their device regains an internet connection.
"Still a lot to do to refine this feature and improve the user experience, making it clear that received tokens are tentative until claimed online, and potentially allowing redemption without requiring user action."
Per release notes, v0.0.7-alpha now "supports scenarios, where an e-cash can be exchanged with both devices staying offline using QR code. Please note, that receiving e-cash offline means trusting the payer until the receiving wallet can connect to the mint and exchange received coins."
Numerous smaller bug fixes and UI improvements
Ability to select coins and send them while the sending device is offline
