Release Notes

The BitShares Core software has been updated to the 3.1.0 Feature Release. The Core software is used to build the validation nodes that perform consensus of all transactions on the BitShares blockchain. This release includes additions and improvements but does not include any changes to the consensus protocol.

Documentation for users may be be found at How BitShares Works.

Documentation for BitShares developers may be now be found at the new BitShares Developer Portal.

Who Should Upgrade?

No upgrade is required by any operator of a validation node. Yet many operators will benefit by upgrading.

Operators of API nodes should upgrade

All node operators will benefit from performance improvements (1608,1621, 1662) including during replay.

Users of the command line interface wallet (CLI) will benefit from new getter commands for transaction signers and the ability to add signatures to partially signed transactions.

Precautions

A replay will automatically be executed after the upgrade.
