May 1, 2026May 2026: Delivered substantial API lifecycle and reliability improvements for akka-sdk. Deprecation cleanup across Timer, JsonSupport, and TestKit APIs consolidated with 'since' annotations and explicit forRemoval, aligning with stable 3.6.0 and removing deprecated APIs through five commits. Implemented workflow lifecycle controls (termination, suspension, and resumption) with logging, idempotency, and rationale, plus tests and docs. Introduced a session memory interceptor to enable redaction and customization without changing core memory. Added large-session history retrieval via memory client with memory-limit management and journal fallback to ensure complete history fetch. No major bugs reported this month.

Apr 1, 2026April 2026 (2026-04) focused on strengthening developer experience and API consistency in akka-sdk. Delivered two features: (1) Documentation Improvements: HTTP Endpoints and Static Resources Handling — consolidated guidance on mapping static resources from the classpath, clarified REST principles and error handling in AGENTS.md, and enhanced docs tooling and Akka SDK docs for clarity and ease of use. (2) API Consistency Enhancement: RecoverStrategy.maxRetries Deprecation — deprecated the instance maxRetries in favor of a static RecoverStrategy.maxRetries, improving API predictability and consistency across workflow recovery strategies. These changes were supported by focused commits to the docs pipeline and API surface alignment. No major bugs fixed were reported in this period based on the provided data.
