Version 2.3.1.3

In this release

Changes:

• Matcher requires two extensions installed on NODE;
• NODE 1.2.17 support.

See below for more information.

Migration

1. Update the NODE
2. Install grpc-server on NODE
   Note: Matcher needs only BlockchainUpdates from grpc-server, please do not enable GRPCServerExtension.
3. Update Matcher Extension
4. Update NODE configuration, add:

   waves {
     extensions += "com.wavesplatform.events.BlockchainUpdates"
     # grpc.host = "0.0.0.0" # Uncomment if Node and Matcher installed on different servers
     blockchain-updates.grpc-port = 6881
   }

5. Remove the NODE state and re-import blockchain (why?)
6. Update Matcher Server configuration:
   1. Specify the host and port of Blockchain Updates extension:

      waves.dex.waves-blockchain-client.blockchain-updates-grpc.target = "NODE_host:6881"

   2. Remove waves.dex.exchange-transaction-broadcast, now it retries attempts by default, see below

Changes

• Support of NODE 1.2.17;
• Matcher Server now depends on Matcher and Blockchain Updates (a part of grpc-server) extensions:
  • The Blockchain Updates extension provides a real-time stream of blockchain changes;
• We made huge efforts to provide the better WebSockets stream (the docs will be available soon!) with less balance glitches during rollbacks and forging new blocks;
• Solved some situations which led to invalid transactions (thus revoked on Blockchain) and mistakenly canceled orders;
• Improved error descriptions in some cases;
• Updated dependencies, including the better library for LevelDB which solves possible DB crashes;
• The documentation is updated;
• And a lot of other changes.
