This release contains several bugfixes and improvements to the stacks-node and stacks-signer binaries, ensuring more consistent block production.
This release is compatible with chainstate directories from 3.x.x.x.x.

The version of stacks-signer compatible with this release is 3.4.0.0.1.0, available at: https://github.com/stacks-network/stacks-core/releases/tag/signer-3.4.0.0.1.0.
