v0.3.17

• Changed minted proofs token format from cashu Token v3 to BitcrB (v4)
• Use NodeId, PublicKey, SecretKey and BillId types internally instead of strings (fully breaking)
  • This breaks all existing databases, since the node ids and bill ids now have the format prefix|network|pubkey- example: bitcrt03f9f94d1fdc2090d46f3524807e3f58618c36988e69577d70d5d4d1e9e9645a4f
  • The prefix is bitcr
  • The network character is as follows:
    • m => Mainnet
    • t => Testnet
    • T => Testnet4
    • r => Regtest
  • The pubkey is a stringified secp256k1 public key
  • Existing apps need to a.) delete their IndexedDB and b.) their localhost (because the mint ID might be in there)
• Removed NodeId trait and replaced it with a concrete method on the corresponding types (breaking API change)
• Rename BillId TS type to BillIdResponse (breaking TS type)

Version: v0.3.17

v0.3.16

• Set the BTC network in the identity and check, if the persisted network is the same as the one configured in the application, failing if it doesn't.
• Nostr npub as primary key in Nostr contacts (breaking DB change)
• Add default mint to nostr contacts as default, so it doesn't have to be added to contacts anymore

Version: v0.3.16

  • Use BillParticipant in parts of the bill where a participant can be anonymous
• Add the possibility to add anonymous contacts
  • They only have Node Id, Name and E-Mail as fields
  • E-Mail is optional
  • This changes the data model for contacts, email and postal_address are now optional

  • The actual payment expiry still only happens 2 workdays after the end of the maturity date,
    or end of the req to pay end of day if that was after the maturity date
  • the request_to_pay_timed_out flag is set after payment expired, not after the req to pay expired
