Countersigning
Warrants
App-level peer blocking
DHT sharding

Chain head coordination
Task scheduling
Experimental DPKI implementation
Added support for 'conductor services', extensions that provide services to all hApps. Added DeepKey, a conductor service offering a distributed PKI, behind an unstable feature flag.

Audited and refactored the integration workflow, which handles received gossip messages and integrates them into the local DHT database.
Local interface stability
Improved resilience of local API WebSocket interface to malformed requests.
Developer tools improvements
Added command-line tools for making calls into a hApp, and improved the scaffolding tool's usability and support of more package managers / front-end dev frameworks.
Countersigning fixes
Changed behavior of experimental countersigning feature to reduce accidental abandonment of session on device failures.
Deferred membrane proofs

Apps no longer fail with an error when no other peers are reachable, improving the local-first experience.
Database split
Refactored the internal database configuration to reduce query bottlenecks.
Interpreted WebAssembly

Initial support for adding peers to block lists, either as a result of user action or automatically in response to invalid activity.
Experimental chain head coordination
Created a feature that allows multiple machines to share the same source chain by side-loading records received from other replicas.
iOS WASM support
Added ability to optimize compiled zomes for embedding in an iOS binary.
Security hardening
