ObolNetwork/charon v0.16.0

v0.16.0 - 2023-06-20

on GitHub

We are excited about this new v0.16.0 release of charon which includes the fixes from our soon to be announced audit, as well as a number of performance and stability improvements.

Notable improvements:

• #1991 is the tracking ticket for multiple fixes related to the Sigma Prime audit. These fixes mostly relate to more robust data validation.
• #2117 adds a new feature flag that A/B tests a new QBFT round timing strategy. The aim is to monitor the performance of this new strategy compared to the existing strategy and hopefully enable it by default in v0.17. This A/B testing feature can be enabled via the --feature-set=alpha or --feature-set-enable=qbft_timers_ab_test flag.
• #1382 introduces a new metric core_tracker_failed_duty_reason_total that counts the number of duty failed duties by type and reason which makes is much easier to identify why duties are failing.

Note that v0.16 doesn't introduce any breaking changes so has the same backwards compatibility as v0.15, it is therefore compatible with both v0.15 and v0.14.
