v8.2.0

Features ✅

• Added getStatsAsync to the @0x/mesh-browser package. (#654).
• Added getOrdersAsync and getOrdersForPageAsync to the @0x/mesh-browser package. (#655).

Bug fixes 🐞

• Update DevUtils contract address to fix intermittent revert issues. (#671).

v8.1.2

Bug fixes 🐞

• Update DevUtils contract to version that removed maker transfer simulation. (#662).
• Fix faulty Go to Javascript conversion logic. (#659).
• Updated dockerfiles to work with Go modules. (#646).
• Update DevUtils mainnet contract address to version that fixes MAP order validation issue (#644).

v8.1.0

Features ✅

• Reduced startup time for Mesh node by only waiting for a block to be processed if Mesh isn't already sync'ed up to the latest block. (#622)
• Increased the maximum size for encoded orders from ~8kB to 16kB (#631).

Bug fixes 🐞

• Fixed a typo ("rendervouz" --> "rendezvous") in GetStatsResponse. (#611).
• Fixed a bug where we attempted to update the same order multiple times in a single DB txn, causing the later update to noop. (#623).
• Fixed a bug which could cause Mesh to exit if a re-org condition occurs causing a block to be added and removed within the same block sync operation. (#614).

v8.0.0-beta-0xv3

Breaking changes 🛠

• Changed the response from @0x/mesh-ts-client's getOrdersAsync endpoint to include the snapshotID and snapshotTimestamp at which the Mesh DB was queried along with the orders found. (#591)
• Increased the default ETHEREUM_RPC_MAX_REQUESTS_PER_24_HR_UTC from 100k to 200k (#596).

Features ✅

• Instead of progressing Mesh forward by a single block on every invocation of the BLOCK_POLLING_INTERVAL, we now attempt to sync as many blocks as necessary to reach the latest block available. This will reduce the chances of Mesh becoming out-of-sync with it's backing Ethereum node (#564)
• Added a new environment variable ENABLE_ETHEREUM_RPC_RATE_LIMITING and config option enableEthereumRPCRateLimiting which can be used to completely disable Mesh's internal Ethereum RPC rate limiting features. By default it is enabled, and disabling can have some consequences depending on your RPC provider. (#584)
• Added a SnapshotTimestamp field to GetOrdersResponse, the return type of the mesh_getOrders RPC method. This way, the caller can know at what point in time the snapshot had been created. (#591)
• Improved batching of events emitted from order events subscriptions (#566)
• Added timestamp to order events (#602)

Bug fixes 🐞

• Fixed an issue where order updates could have been missed if Mesh discovered blocks but didn't have time to process them before getting shut down. Now, blocks are only persisted to the DB once any order updates resulting from it have been processed. (#566).
• Fixed a race-condition when adding new orders to Mesh which could result in order-relevant events being missed if they occured very soon after the order was submitted and the order validation RPC call took a long time (#566).
• Upgraded the web3-provider dependency used by @0x/mesh-rpc-client in order to fix a bug where it was requiring either process OR window to exist in the global scope (#601).
• Fixed an issue where the internal Ethereum RPC rate limiter could be too aggressive in certain scenarios (#596).
• Add a default RPC request timeout of 30sec to all non-subscription requests sent by @0x/mesh-rpc-client to avoid the client from hanging endlessly if it misses a response due to network disruption (#603).

v7.0.1-beta-0xv3

Bug fixes 🐞

• Fixed an oversight which granted immunity from bandwidth banning for any peer using a relayed connection (#509).
• Fixed a typo in the @0x/mesh-browser package that resulted in some config options not being passed through correctly (#502).
• Fixed a bug in ETH JSON-RPC rate limiter where not all dates were being properly converted to UTC, causing Mesh to malfunction if the local time was a day earlier or later than UTC. (#505)
• Fixed a bug in the TypeScript RPC client that prevented orders from being added (#514).

v7.0.0-beta-0xv3

Breaking changes 🛠

Note: This release will require wiping your Mesh's DB before upgrading. The DB location defaults to ./0x_mesh/db.

• Removed RPC_PORT environment variable. The new RPC_ADDR environment variable allows specifying both the interface and port (#487).
• Due to security concerns and new rate limiting mechanisms, the default bind address for the RPC API has changed from 0.0.0.0 to localhost. Users who previously did not set RPC_PORT may need to now manually set RPC_ADDR to enable other applications to access the RPC API. If you are using Docker Compose, we recommend using links. If you do need to set RPC_ADDR to bind on 0.0.0.0, please be aware of the security implications and consider protecting access to Mesh via a third-party firewall. (See #444 and #487 for more details).
• Changed the EXPIRED event such that it is emitted when an order is expired according to the latest block timestamp, not anymore based on UTC time. (#490)
• Removed the EXPIRATION_BUFFER_SECONDS env config since we no longer compute order expiration using UTC time. (#490)

Features ✅

• Added an UNEXPIRED order event kind which is emitted for orders that were previously considered expired but due to a block-reorg causing the latest block timestamp to be earlier than the previous latest block timestamp, are no longer expired. (#490)
• Added support for decoding Axie Infinity Transfer and Approve ERC721 events which differ from the ERC721 standard. (#494)

Bug fixes 🐞

• Fixed a bug in the Go RPC client which resulted in errors when receving order events with at least one contract event (#496).

v7.2.1-beta-0xv3

Bug fixes 🐞

• Fixed a bug which could cause Mesh to crash with a nil pointer exception if RPC requests are sent too quickly during/immediately after start up (#560).

v7.1.1-beta-0xv3

Bug fixes 🐞

• Fixed a bug where the internal order event feed could be come blocked, rendering Mesh unable to receive any new orders or update existing ones (#552).
