This software update is a consensus changing release and the implementation of the proposed cost changes in SIP-012. This release's chainstate directory is compatible with chainstate directories from 2.0.11.4.0. However, this release is only compatible with chainstate directories before the 2.05 consensus changes activate (Bitcoin height 713,000). If you run a 2.00 stacks-node beyond this point, and wish to run a 2.05 node afterwards, you must start from a new chainstate directory.

Added

  • At height 713,000 a new costs-2 contract will be launched by the Stacks boot address.

Changed

  • Stacks blocks whose parents are mined >= 713,000 will use default costs from the new costs-2 contract.
  • Stacks blocks whose parents are mined >= 713,000 will use the real serialized length of Clarity values as the cost inputs to several methods that previously used the maximum possible size for the associated types.
  • Stacks blocks whose parents are mined >= 713,000 will use the new block limit defined in SIP-012.

Fixed

  • Miners are now more aggressive in calculating their block limits when confirming microblocks (#2916)
