[0.7.0r] - 2024-04-23​

Breaking changes 💔​

  • Deadline for transfers: Added deadline field to init_transfer. Transfers applied after this timestamp will fail and can only be reverted.
  • Moved latest_time: The latest_time field has been relocated from the accounts module to the utils module.
  • Function renaming:
    • Renamed _register_account() to register_account().
    • Renamed add_auth_descriptor_to_account function to add_auth_descriptor.
    • Renamed _add_signer to add_signers.
    • Renamed ft4.get_auth_descriptor_nonce to ft4.get_auth_descriptor_counter.
  • Version requirement: Requires Rell 0.13.10.
  • Entity changes:
    • Updated entity ft4.crosschain.applied_transfers.
    • Updated entity ft4.account_creation_transfer.
    • Added transaction field to the applied_transfers entity.
  • Operation changes:
    • Removed ft4.register_account_evm_signatures, now use ft4.evm_signatures instead.
    • Removed ft4.delete_all_auth_descriptors_exclude, replaced with ft4.delete_all_auth_descriptors_except_main.
  • Function argument changes:
    • Removed is_strict argument from authenticate() function. auth_handlers will now resolve to the most specific handler if no operation auth handler is found.
  • Account creation updates:
    • Removed signature verification from create_account_with_auth. Signatures must now be verified separately using verify_signers.
    • create_account_with_auth will now create an account with an ID based on the hash of signers if the account_id argument is not provided.
  • Configuration changes:
    • All module arguments for FT4 submodules in YML config now include an additional core component in the module path. For example, accounts module arguments should be defined under lib.ft4.core.accounts instead of lib.ft4.accounts.
  • Module removal: Removed ft4_basic and ft4_basic_dev modules.

Changed 🪙​

  • Revised internal structure of FT4 submodules: External modules are now imported alongside core modules. For instance, importing lib.ft4.accounts will also import the associated operations and queries. If needed, you can still import accounts entities and functions without the operations and queries by using lib.ft4.core.accounts.

Added ✅​

  • Reversion of incomplete cross-chain transfers: Added support to revert incomplete cross-chain transfers after the deadline has passed.
  • Recall unclaimed register account transfers: Added functionality to recall unclaimed register account transfers after the timeout period has expired.

  • Default login configuration: Set a 1-day expiration for default login configuration.

  • New queries:

    • get_last_pending_transfer_for_account: Returns the most recent pending cross-chain transfer matching the provided parameters (sender, target chain, recipient, asset, amount).

[0.2.0r] - 2023-12-22​

warning

This version is incompatible with older versions. To upgrade, you will need to perform a database migration. For more information, refer to this page.

Breaking changes 💔​

  • Paginated queries: Queries get_accounts_by_participant_id and get_account_auth_descriptors_by_participant_id are now paginated. Update your code to handle these changes.
  • Paginated queries: Removed non-paginated queries _get_accounts_by_auth_descriptor_id, _get_asset_balances, and _get_all_assets. Use their paginated counterparts without the leading _. Replaced get_asset_by_name with the paginated get_assets_by_name.
  • Rules structure: Revised the internal structure of rules. Existing auth descriptors using rules will no longer function and will cause runtime errors.
  • Address functions removed: Deprecated evm_address_from_pubkey and evm_address_from_privkey. Use crypto.eth_pubkey_to_address and crypto.eth_privkey_to_address from the Rell standard library.
  • Function return types: create_account_with_auth now returns account instead of byte_array. add_auth_descriptor_to_account now returns account_auth_descriptor instead of byte_array.
  • Rate limit config: Updated format for rate limit configuration.
  • brid to blockchain_rid: Renamed all instances of brid to blockchain_rid to clarify the acronym. This affects:
    • asset.issuing_brid -> asset.issuing_blockchain_rid
    • Queries and message templates that previously used {brid} now use {blockchain_rid}.
    • asset_origin.origin_brid -> asset_origin.origin_blockchain_rid
  • Renamed terms: Updated terminology related to auth descriptors:
    • Queries: get_account_auth_descriptors_by_participant_id -> get_account_auth_descriptors_by_signer, get_accounts_by_participant_id -> get_accounts_by_signer.
    • Accounts module: Renamed single_sig_args.pubkey to single_sig_args.signer, multi_sig_args.pubkeys to multi_sig_args.signers, get_participants to get_signers, auth_descriptor_participant to auth_descriptor_signer, and functions like get_paginated_auth_descriptors_by_participant_id to get_paginated_auth_descriptors_by_signer.
    • Internals: Renamed _add_auth_participant to _add_signer, and _add_eth_auth_participant to _add_eth_signer.
  • Transfer history: Removed transfer_args and entry_index from get_transfer_history_entry and get_transfer_history queries.

Added ✅​
