• require authorization to install a new Cluster
• performance improvements to transactional locking
• replace App with Service in the Python client
• update linear algebra and ml services and tests to use Service with dynamic installation
• refactor Chain to support a generic mutable subject
• refactor tc_transact::File to support a generic key type
• bugfixes to Chain recovery in single-host mode
• security updates to dependency versions

• added hash_of for consistent hashes of TinyChain States
• refactored URI to replace MethodSubject
