Changes
This is a major release, with many new features and improvements.
- No more dedicated factory. Instances are now deployed from the Zodiac Module Proxy Factory.
- All HSGs are now Multi, ie they can be configured with multiple signers hats
- Full compatibility with other Safe & Zodiac modules, ie HSG is now a Zodiac modifier to which Safe modules and a guard can be attached
- Simpler and more legible valid signer logic
- Stronger protections against signers changing Safe state, including explicit protection against signers changing the fallback handler
- Delegatecalls are now restricted to a set of approved target contracts, for improved state safety while retaining ability to batch calls via MultiSend
- HSG can be be detached from the Safe, or the Safe can be migrated to a new HSG (by the owner)
- Removed the maxSigners parameter, which in practice only complicated initial configuration unnecessarily
- Uses transient storage for significant gas savings
- Signer permissions can optionally be claimed on behalf of accounts wearing a signersHat, for improved automation and onboarding UX
- HSG can be locked, preventing any changes to configuration
