Release 2.05.0.0.0

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)

Release 2.0.11.4.0

This software update is a point-release to change the transaction
selection logic in the default miner to prioritize by an estimated fee
rate instead of raw fee. This release's chainstate directory is
compatible with chainstate directories from 2.0.11.3.0.

Added

• FeeEstimator and CostEstimator interfaces. These can be controlled
  via node configuration options. See the README.md for more
  information on the configuration.
• New fee rate estimation endpoint /v2/fees/transaction (#2872). See
  docs/rpc/openapi.yaml for more information.

Changed

• Prioritize transaction inclusion in blocks by estimated fee rates (#2859).
• MARF sqlite connections will now use mmap'ed connections with up to 256MB
  space (#2869).

Release 2.0.11.3.0

This software update is a point-release to change the transaction selection logic in the default miner to prioritize by fee instead of nonce sequence. This release's chainstate directory is compatible with chainstate directories from 2.0.11.2.0.

Added

• The node will enforce a soft deadline for mining a block, so that a node operator can control how frequently their node attempts to mine a block regardless of how congested the mempool is. The timeout parameters are controlled in the [miner] section of the node's config file (#2823).

Changed

• Prioritize transaction inclusion in the mempool by transaction fee (#2823).
