Change Log

unreleased

0.23.0 (2022-12-16)

• Updated: updated dependencies, notably web3==5.31.0
• Updated: no longer use unlocked node to handle transactions, request nonce directly from node (mainly useful for TL e2e tests)

0.22.0 (2021-10-20)

• Updated: dropped support for websocket connection to the blockchain node. It was not working due to a conflict in between the concurrency library used by web3's websocket and gevent.
• Fixed: get mediation fees endpoint no longer crashing due to network migration events.

0.21.0 (2021-04-28)

• Updated: Add transfer argument to schema for TrustlineUpdateRequest events corresponding to change in CurrencyNetworkV2 contract
• Updated: Remove interests with a value of 0 for endpoint to query list of accrued / paid interests (BREAKING)

0.20.3 (2021-03-31)

• Updated: Make relay exit when greenlet for graph sync dies.
• Fixed: Only publish most recent events on websocket for trustline update and network balance update. This fixes a bug that stopped the updating of the currency network graph in certain situations.
• Fixed: Relay crash on logging with insufficient parameters.

0.20.2 (2021-03-19)

• Fixed: No longer publish events for balance changes from filter for BalanceUpdates and TrustlineUpdates Now uses graph updates from ethindex to publish information

0.20.1 (2021-02-12)

• Fixed: Correclty fetch the is_frozen status of currency networks at start up. previously, networks where start unfrozen by default and synced further.

0.20.0 (2021-02-12)

• Updated: Use ethindex to update is_frozen status of network graphs instead of filters requires ethindex>=0.3.5

0.19.0 (2021-01-26)

• Changed: Update major dependencies, notably web3 version 5.9.0
• Changed: add filtering by contract type to user events endpoint /users/:user/events?type=:type&fromBlock=:fromBlock&contractType:=contractType
• Changed: Update internal trustlines graph using graphfeed table populated by the ethindex. requires py-eth-index version 0.3.4
• Changed: No longer fully sync the graph every full_sync_interval seconds. This should be unnecessary as we rely on the indexer to sync the graph and it is reorg safe.
• Removed: support for config keys relay.updateNetworksInterval and relay.update_indexed_networks_interval
• Removed: deprecated config trustline_index.full_sync_interval which is unused.
• Added: endpoint for getting mediation fees earned by user /networks/:network/users/:user/mediation-fees?startTime=:timestamp&endTime=:timestamp
• Added: endpoint to get debt of user in all currency networks GET /users/:userAddress/debts
• Added: endpoint to get total transferred sum between users in time window GET /networks/:network/users/:sender/transferredSums/:receiver?startTime=:timestamp&endTime=:timestamp
• Added: Config key config.trustline_index.sync_interval the time in seconds in between two fetch fetch of graph updates from the database graphfeed

• Change firebase push notifications to data push notifications
• Remove event_query_timeout from relay config as it is not used anymore (BREAKING)
• Add endpoint to get paid delegation fees via tx hash: GET /delegation-fees?transactionHash=hash this endpoint returns a list of all delegations fees paid within the transaction with given hash
• Add extraData to response of endpoint GET /transfers?options... which returns a list of information for identifies transfer
• No longer watch address file for new currency networks, exchange, unwEth, identity proxy factory addresses
• Deprecate config relay.update_indexed_networks_interval: it is no longer used and should be removed

• Added: identityImplementation field to response of endpoint about identity information api/v1/identities

0.15.0 (2020-04-21)

• Add endpoint to get all events of a trustline: /networks/<network_address>/users/<user_address>/trustlines/<counter_party_address>/events
• Add logIndex and blockHash to events returned from endpoints
• Add endpoint GET /transfers?options... to get a list of information for transfers either via enveloping tx hash, or via the transfer event or via a related balance update event identified via block hash and log index.
• Add endpoint to get list of all trustlines in a currency network GET /networks/:networkAddress/trustlines
• Change config of relay to enforce having no currency_network if delegation fees are set to {'base_fee'=0, 'gas_price'=0}. (BREAKING)
• Change config so that if no accepted fees are specified, no fees will be accepted, i.e. the delegate will not pay for meta-tx. (BREAKING)
• Change: Delegate will now check the value of feeRecipient for meta-tx, it has to be the delegate's address or the zero_address to be correct. The zero address is only for backwards compatibility and will be removed in the future. (BREAKING)
• Change: No longer use the pending block to get events, the graph is now updated on the latest block instead. (BREAKING)
• Deprecate transactionId in events for transactionHash. It will be removed in future versions.
• Deprecate return of currency network address if delegation fees are 0. In the future it will return null.
• Deprecate undocumented field address returned when querying trustlines information (for a user, for a network, in between users of a network, for a user in a network). If you were using it, change to counterParty. Will be removed in future release.

0.14.0 (2020-03-02)

• Add endpoint to ask for transaction status
• Add endpoint to ask for meta-transaction status
• Improve performance of log listener by reducing the number of registered log listeners in the blockchain node. This should reduce cpu usage of the relay.
• Improve performance of user-events endpoint (users/<>/events). THis should reduce the number of connections to the sql db and improve the response time.

The installation has become easier, since populus and solc isn't required anymore. Therefore tl-deploy isn't being installed anymore.
