BitShares Core "Splash" 5.1.0 Release

Release Notes

The BitShares Core software has been updated to the 5.1.0 Feature Release. The codename of the 5.x releases is "Splash". The Core software is used to build the validation nodes that perform consensus of all transactions on the BitShares blockchain. This release includes additions, improvements and bug fixes 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 found at the BitShares Developer Portal.

Who Should Upgrade?

Public API nodes should upgrade to support client software that attempt to use the new APIs.

Private API nodes may or may not upgrade depending on the use cases.

Pure validation nodes E.G. block producers and seed nodes are not required to upgrade.
