March 2026 (2026-03) monthly summary for polkadot-docs: Key features delivered span SubXT 0.50.0 migration across code samples and docs with dependency updates and build fixes, aligning tutorials to the new block-centric API (at_current_block, transactions, runtime_apis) and boosting performance. A session key management overhaul was implemented using the Polkadot Hub workflow, deprecating the relay-chain method and adding guidance for author_rotateKeysWithOwner RPC, deposits, and purging semantics. The Zombienet tutorial was refreshed for Paseo deployment, replacing rococo-local with Paseo and delivering a focused, SEO-friendly step-by-step guide. Documentation structure received a comprehensive overhaul with broken-link fixes, test-name updates, and enhanced operator proxy guidance, while CI badges were added across guides to improve build visibility. These efforts reduce maintenance load, speed API adoption, strengthen security/compliance in key management, and improve developer onboarding and cross-team collaboration.
