Jun 1, 2026June 2026: Delivered two high-impact initiatives in smartcontractkit/documentation. 1) Deprecation of the legacy Webhook job type with a migration path to the Chainlink Runtime Environment (CRE), documented in changelog and docs (commit 44e691dd53c5fe8f103401748bbf14f4f2b2f38e; referenced in #3830). 2) Data Feeds infrastructure upgrade on Optimism to improve performance and redundancy, with a dedicated changelog entry and alignment to the formats used for Arbitrum/Base/BSC (commit d5ba9cfa0b2dd6019cf8617a7e44aa5d62456bda). Outcomes include improved developer experience, reduced legacy maintenance burden, and a more resilient multi-network data infrastructure. Collaboration across teams is evidenced by co-authored commits.
