BitShares Core 2.0.181105 Release Notes
The BitShares Core software has been updated to the 181105 Feature Release. The Core software is used by validation nodes which perform consensus of all transactions on the BitShares blockchain. This release includes new features, optimizations, and bug fixes but does not include any changes to the consensus protocol.
No action is required if you do not operate a validation node or the command line interface (CLI) wallet.
Numerous performance improvements have been made to the software that will benefit all operators of validation nodes including block producers, seed nodes, and API nodes, especially those using the Elasticsearch plugin.
Documentation for BitShares developers may be now be found at the new BitShares Developer Portal (https://dev.bitshares.works).
Who Should Upgrade?
No upgrade is required by any operator of a validation node. Yet many operators will benefit by upgrading.
- All operators will benefit from performance improvements (915, 1327, 1359) and fixes (1024, 1203, 1286, 1325).
- Operators of block producing nodes will benefit from performance improvements (1251), safety measures (1252), and fixes (1266, 1332, 1364).
- Operators of API nodes including Elasticsearch APIs will benefit from improvements to data availability (1351, 1352) and performance (1049, 1271, 1356).
- Users of the command line interface (CLI) wallet will also benefit from improvements (1195, 1248).
Upgrade Process
Precautions
Precaution 1
Operators of API nodes that service client software that expect to receive updates about all data on the blockchain by default (such as BitShares Reference Wallet before 180401), as opposed to narrowly subscribed data, should ensure that their API nodes are configured with the enable-subscribe-to-all set to true due to Pull Request 1049.
