Notes
Nimbus v1.6.0 is a low-urgency performance optimisation release with improved peer management.
v1.6.0 adds support for the Keymanager API (currently in BETA):
https://nimbus.guide/keymanager-api.html
As well as a comprehensive set of metrics for validator performance monitoring:
https://nimbus.guide/validator-monitor.html
Improvements:
- Tuned peer management: reduces the likelihood of missed attestations
- If you've seen frequent "No peers for topic" in your logs, this release will help
- Improved buffer management in the networking layer: reduces both CPU and memory usage.
- Further optimised batch verification of gossip messages: provides a 2-fold improvement in throughput.
- Comprehensive set of metrics for live validator performance monitoring in Grafana and support for producing detailed historic reward analysis in
ncli_db(note thatncli_dbis available only when compiling from source at the moment). - Support for the new Keymanager API: add, remove, and migrate validators on the fly (BETA).
- Blazingly fast historical traversals in the REST API for beacon chain data mining: state caching brings up to a 10x speed-up in some common usage patterns (e.g. obtaining historic data slot by slot or epoch by epoch).
- 3x speed-up in snappy compression and decompression.
- Support for obtaining JSON payloads from the REST API.
Urgency guidelines
low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks
medium-urgency: may contain an important stability fix, it is better to update sooner rather than later
high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
