Release Notes

The BitShares Core software has been updated to the 5.2.1 Bugfix Release. The codename of the 5.x releases is "Splash". The BitShares Core software is used to build the validation nodes that perform consensus of all transactions on the BitShares blockchain. This release includes fixes about node stability and documentations 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

It is recommended that all nodes be upgraded to benefit from the stability improvements introduced in this release and the benefits introduced in the 5.2.0 Feature Release, although it is not required.

How To Upgrade


  • For nodes running versions earlier than 5.2.0, a blockchain replay will automatically be performed after the validation node software is restarted. This typically takes a few hours on a modern CPU.

How to Upgrade from Source Code


  • The code base requires a compiler that supports the C++ 14 standard
  • The minimum supported boost version is 1.58, the maximum is 1.74
  • The minimum supported CMake version is 3.2
  • For Ubuntu users, it is now supported and recommended to build in Ubuntu 20.04 LTS
