June 2026: Documentation improvements for CopilotKit self-hosting to enhance onboarding and artifact accessibility. Focused on fixing navigation and links in the self-hosting guide to ensure readers reach the correct setup steps and publicly accessible chart releases.

May 2026 monthly summary for CopilotKit/CopilotKit: Delivered robust React Native support with a new @copilotkit/react-native package, demo app, tests, and documentation; refactored react-core context and headless hook exports for better modularity; integrated RN package into the release system to streamline packaging and releases; introduced CopilotModal and CopilotSidebar RN components and updated build/config/docs. Fixed RN streaming crash and agentId inconsistencies; hardened SDK validation, error handling, and dispatch, and expanded test coverage (including pytest-asyncio) to improve reliability. Result: faster RN adoption, more stable cross-platform experiences, and streamlined release processes.

April 2026 monthly summary for CopilotKit/CopilotKit focused on increasing streaming reliability, performance, and developer productivity through a set of throttle-driven enhancements, documentation updates, and stability fixes across React and Angular integration points. Key features delivered: - Documentation: Updated MCP server URLs from SSE to HTTP transport (commit a6557654...). Adjusted MCP setup docs and removed the obsolete Tadata callout. - Streaming throttling: Added throttleMs option to useAgent and wired through CopilotChat; introduced provider-level defaultThrottleMs fallback and centralized throttle logic in CopilotKitCore; enabled per-token onMessagesChanged throttling with leading+trailing behavior (commits 30916a6a...). - Throttle core hardening: Consolidated throttleMs handling into single useEffect; added extensive input validation and edge-case tests; improved JSDoc and test reliability (multiple fixes including 3cdaaf08..., d1357083..., c2dcee27...). - UI performance improvements: CopilotChatInput container dimension caching to reduce per-keystroke reflows; refined ResizeObserver usage and test coverage (d9125fc0..., 8986a472..., 27bde85b...). - Documentation and guidance: Expanded throttle-related docs, performance guidance, and middleware usage; updated performance tip snippets and routed docs changes. - Quality and testing: Refactored tests with message factories for type-safety; extracted shared helpers; added ALLOWED_KEYS and emitError centralization; improved error monitoring across React/Angular. - Cross-framework readiness: Central throttle orchestration in CopilotKitCore; decoupled AgentStore from core; prepared ground for Angular parity with onRunErrorEvent and throttling behavior. Major bugs fixed: - ThrottleMs validations hardened and unified (zero/edge values treated safely); extensive trailing-edge fixes and tests added; improved test coverage and error reporting. - Strict Mode/UI issues fixed in example apps; ResizeObserver and cache invalidation race conditions resolved; improved test mocks and hygiene. - SDK/Python/tool-call emission alignment: ensure assistant messages emitted with tool-calls for tool-based tool-lantern flows. Overall impact and accomplishments: - Significantly reduced UI jitter and unnecessary re-renders in streaming scenarios, delivering a smoother user experience and faster perceived responsiveness. - Stronger type safety, error handling, and observability, reducing production incidents and accelerating debugging. - Documentation improvements and test hygiene enhancements improve onboarding and long-term maintainability across React and Angular integrations. Technologies/skills demonstrated: - TypeScript, React patterns (useEffect, ResizeObserver), perf optimization and caching, TanStack Pacers Throttler migration, and cross-framework considerations (Angular/React). - Comprehensive testing strategies, including message factories, edge-case coverage, and robust error monitoring integration.
