v0.4.12

• Added actions to BitcreditBillResult, with bill_actions, that are calculated based on which bill actions the caller is currently allowed to do (breaking DB and API change)

  • Offer to Sell (buying_deadline) - min. UTC end of day of the block timestamp
• Add basic input validation and sanitization
  • removed language from bills (breaking DB change)
  • added Country type that validates against a list of valid countries (breaking DB change)

• Fix it so that Anon holders of a bill can do recourse (breaking DB and API change)
  • recourser went from BillIdentParticipant to BillParticipant
• Added endpoints identityApi.dev_mode_get_full_identity_chain() and companyApi.dev_mode_get_full_company_chain(company_id) to show the full identity and company chains as JSON in dev mode
• Fixed request to recourse validation
  • The bill is not blocked, if a req to recourse expired, or was rejected
  • It's now possible to recourse against the same person again
  • The last person in the chain can now reject a recourse (was broken before)
  • get_past_endorsees is calculated differently now - holders can only recourse against parties before the first block where they became a holder in the bill, even if they have multiple endorsement blocks in the bill
• Cleanup deps, replace bcr-wdc-* deps with bcr-common, improve Github workflows

Version: v0.4.9

v0.4.8

• Fix reject block propagation
• Add last_block_time to LightBitcreditBillResult

Version: v0.4.8

v0.4.7

      return { ...block, data: JSON.parse(block.data) };
    })

• Changed default relay to wss://bcr-relay-dev.minibill.tech
• Change endorsements endpoint, making sure all endorsees (also anon) are displayed (breaking for API because of the return type)
• Add last_block_time to status of BitcreditBillResult (breaking DB and API), so bill responses can be ordered by their last change
• For the balance endpoint, don't add to contingency, if the current user is only in the guarantee chain as an anon endorsee (breaking DB change)

Version: v0.4.6
