casper-network/casper-node v1.5.4 on GitHub

1.5.4

New environment variable CL_EVENT_QUEUE_DUMP_THRESHOLD to enable dumping of queue event counts to log when a certain threshold is exceeded.
Add initial support for private chains.
Add support for CA signed client certificates for private chains.
Add a Highway Analysis tool for checking the state of the consensus.

Minimum block time reduced from 32.768s to 16.384s, with corresponding changes to related chainspec settings:
- core.minimum_block_time reduced to 16384 ms.
- core.round_seigniorage_rate reduced to [7, 175070816].
- highway.block_gas_limit reduced to 4_000_000_000_000.
The state_identifier parameter of the query_global_state JSON-RPC method is now optional. If no state_identifier is specified, the highest complete block known to the node will be used to fulfill the request.
state_get_account_info RPC handler can now handle an AccountIdentifier as a parameter.
Replace the sync_to_genesis node config field with sync_handling.
- The new sync_handling field accepts three values:
  - genesis - node will attempt to acquire all block data back to genesis
  - ttl - node will attempt to acquire all block data to comply with time to live enforcement
  - nosync - node will only acquire blocks moving forward
Make the network.estimator_weights section of the node config more fine-grained to provide more precise throttling of non-validator traffic.

The section consensus.highway.round_success_meter has been removed from the config file as no longer relevant with the introduction of a new method of determining the round exponent in Highway.

Now possible to build outside a git repository context (e.g. from a source tarball). In such cases, the node's build version (as reported vie status endpoints) will not contain a trailing git short hash.
Remove an error that would unnecessarily be raised when a node includes its highest orphaned block within the current era.
Short-circuit initialization of block and deploy metadata DB to resolve delays after an upgrade.
