CHANGELOG

v4.2.0

May 1, 2024

API BREAKING

  • Provider
    • Assigning a key that is already assigned by the same validator will now be a no-op instead of throwing an error. (#1732)

FEATURES

  • Provider
    • Enable Opt In and Top N chains through gov proposals. (#1587)
    • Adding the Partial Set Security (PSS) feature cf. ADR 015. PSS enables consumer chains to join ICS as Top N or Opt In chains and enables validators to opt to validate the consumer chains they want. (#1809)
    • Introduce power-shaping features for consumer chains. The features: (i) allow us to cap the total number of validators that can validate the consumer chain, (ii) set a cap on the maximum voting power (percentage-wise) a validator can have on a consumer chain, and (iii) introduce allowlist and denylists to restrict which validators are allowed or not to validate a consumer chain. (#1830)
