Month: 2025-05 Key features delivered: - Deprecation annotation consistency across proto definitions in temporalio/api and temporalio/api-go by aligning //Deprecated comments with the [deprecated = true] attribute. No functional changes. Major bugs fixed: - None. This work eliminates inconsistency in deprecation signaling, reducing risk of misinterpreting deprecated APIs. Overall impact and accomplishments: - Provides a single source of truth for API deprecation status across languages, improving developer onboarding, client experience, and future deprecation planning. Establishes standardized metadata handling that supports downstream tooling. Technologies/skills demonstrated: - Protobuf tooling and proto definition hygiene, cross-repo coordination, documentation standards, and change management under issue #592.

November 2024 focused on API surface hygiene, stability, and protobuf serialization alignment across temporalio/api and temporalio/api-go. Delivered features to simplify the API surface and ensure client compatibility, while reinstating WIRE_JSON as the serialization baseline to fix regressions. These efforts reduce maintenance burden, improve onboarding, and enhance long-term reliability for API consumers.
