This is a history of changes to k13labs/failsage

0.2.0 - 2025-10-22

Features

• Map-based Policy Building: Policies can now be defined using plain Clojure maps with a :type key to support policies as data.
  • All policy types support map format: :retry, :circuit-breaker, :fallback, :timeout, :rate-limiter, :bulkhead
  • Maps can be used directly with execute, execute-async, and executor functions
  • Policy maps are automatically built via the IPolicyBuilder protocol.
  • Mix map-based and function-based policies seamlessly in policy composition
  • Example: (fs/execute {:type :retry :max-retries 3} (call-service))
  • Stateful policy maps (circuit breaker, rate limiter, bulkhead) throw exceptions when used directly to prevent state loss
• Added policies function to explicitly create policy lists from regular policies, maps, or mixed combinations

Changes

• Removed some redundant functions from the failsage.impl namespace, and moved the IPolicyBuilder protocol to thefailsage.core` namespace.
• Extended IPolicyBuilder protocol to support IPersistentMap interface for automatic policy building
