The latest version available is cardano-node pre-release 10.5.0.

Configuration files

Compatible with cardano-node pre-release 10.5.0

NOTE:
The non-block-producer node config has `PeerSharing` enabled by
default, so should not be used with block-producers.

Additionally, avoid connecting a block-producer not using p2p to a p2p
PeerSharing enabled relay as the block-producer's IP will be leaked.

• Node Config (Block-producers)
• DB Sync Config
• Submit API Config
• Node Topology
• Peer Snapshot
• Byron Genesis
• Shelley Genesis
• Alonzo Genesis
• Conway Genesis
• Compiled guardrails script

Ouroboros Genesis Mode

Ouroboros genesis mode is now the default consensus mode on preview and preprod testnets starting with node 10.5.0. If needed, use of praos mode and the bootstrap peers found in the above topology file can be reverted to by setting:

• Node config's ConsensusMode option to a value of PraosMode

UTXO-HD

Users migrating from a node version older than 10.4.1 should also read the 10.4.1 release notes and the consensus migration guide to properly configure the node and convert the database such that a replay from genesis can be avoided.

Guardrails reference script UTxO

For convenience, the guardrails script has been put on a UTxO so that it can be used as reference script in Treasury Withdrawal and Update Protocol Parameter proposals.
