Features

  • update identity contracts' purpose handling
    • to match updated purpose handling

Features

  • Added deactivation feature for DidRegistry

Version 2.4.0

Features

  • add delegation support to KeyHolder
    • delegated calls require a signed hash, that is built from transaction input, identity address and its transaction nonce
    • delegated calls can be executed by anyone, but require the signer to have correct keys

  • update IdentityHolder with migrateIdentity function, that allows to migrate identities into it, as long, as identity is not claimed yet

Fixes

  • update IdentityHolder
    • properly returns created identity from createIdentity
    • getter functions uses view modifier
  • update gas price in contract deploy script to 200GWei

  • bytecodes to keep in reduced compiled file can be given as propety allowedByteCodes to constructor
  • dependencies between libraries can be given as property libraryDependencies to constructor
  • setting property compileContracts to true now compiles contracts, even if source files have not changed since last compile time
  • update build-contracts to deploy missing libraries
  • add deployedAt for libraries in compiled contracts
  • add flag disableSubVerifications to verifications
  • wallet only keeps hash of original input and deletes data after executing it

Deprecations

  • DSRolesPerContract uses own lib for logic
