Release v0.24.0

2020-09-04

One new API endpoint allows cancelling multiple orders simultaneously, either all orders by market, a single order in a specific market, or just all open orders.

Other than that it's mainly bugfixes, many of which fix subtly incorrect API output.

• #2167 Ensure events in the event bus maintain their order
• #2178 Fix API returning incorrectly formatted orders when a party has no collateral

v0.24.0-pre1

Release v0.24.0

Release v0.23.1

*2020-08-27*

This release backports a fix from the forthcoming 0.24.0 release that fixes a GraphQL issue with the new `Asset` type. When fetching the Assets from the top level, all the details came through. When fetching them as a nested property, only the ID was filled in. This is now fixed.

Improvements:

- #2140 GraphQL fix for fetching assets as nested properties

v0.23.0: *2020-08-10*

2020-08-10

This release contains a lot of groundwork for Fees and Auction mode.

Fees are incurred on every trade on Vega. Those fees are divided between up to three recipient types, but traders will only see one collective fee charged. The fees reward liquidity providers, infrastructure providers and market makers.

• The liquidity portion of the fee is paid to market makers for providing liquidity, and is transferred to the market-maker fee pool for the market.
• The infrastructure portion of the fee, which is paid to validators as a reward for running the infrastructure of the network, is transferred to the infrastructure fee pool for that asset. It is then periodically distributed to the validators.
• The maker portion of the fee is transferred to the non-aggressive, or passive party in the trade (the maker, as opposed to the taker).

Auction mode is not enabled in this release, but the work is nearly complete for Opening Auctions on new markets.

💥 Please note, this release disables order amends. The team uncovered an issue in the Market Depth API output that is caused by order amends, so rather than give incorrect output, we've temporarily disabled the amendment of orders. They will return when the Market Depth API is fixed. For now, amends will return an error.

New

• #2092 💥 Disable order amends
• #2027 Add built in asset faucet endpoint
• #2075, #2086, #2083, #2078 Add time & size limits to faucet requests
• #2068 Add REST endpoint to fetch governance proposals by Party
• #2058 Add REST endpoints for fees
• #2047 Add prepareWithdraw endpoint

Improvements

• #2061 Fix Network orders being left as active
• #2034 Send KeepAlive messages on GraphQL subscriptions
• #2031 Add proto fields required for auctions
• #2025 Add auction mode (currently never triggered)
• #2013 Add Opening Auctions support to market framework
• #2010 Add documentation for Order Errors to proto source files
• #2003 Add fees support
• #2004 Remove @deprecated field from GraphQL input types (as it’s invalid)
• #2000 Fix rejectionReason for trades stopped for self trading
• #1990 Remove specified tickSize from market
• #2066 Fix validation of proposal timestamps to ensure that datestamps specify events in the correct order
• #2043 Track Event Queue events to avoid processing events from other chains twice

v0.23.0-pre3

Correct bash typo

Release v0.22.0

*2020-07-20*

This release primarily focuses on setting up Vega nodes to deal correctly with
events sourced from other chains, working towards bridging assets from Ethereum.
This includes responding to asset events from Ethereum, and support for
validator nodes notarising asset movements and proposals.

It also contains a lot of bug fixes and improvements, primarily around an
internal refactor to using an event bus to communicate between packages. Also
included are some corrections for order statuses that were incorrectly being
reported or left outdated on the APIs.
