## v0.27.0 ## v0.27.0
This release contains some breaking changes to the block and p2p protocols,
but does not change any core data structures, so it should be compatible with
existing blockchains from the v0.26 series that only used Ed25519 validator keys.
Blockchains using Secp256k1 for validators will not be compatible. This is due
to the fact that we now enforce which key types validators can use as a
consensus param. The default is Ed25519, and Secp256k1 must be activated
explicitly.
It is recommended to upgrade all nodes at once to avoid incompatibilities at the
peer layer - namely, the heartbeat consensus message has been removed (only
relevant if `create_empty_blocks=false` or `create_empty_blocks_interval > 0`),
and the proposer selection algorithm has changed. Since proposer information is
never included in the blockchain, this change only affects the peer layer.
