Latest Feature Releases

ChatSDKs major releases

This release brings a big step forward in consistency, developer experience, and scalability across platforms—while still keeping each SDK idiomatic to its ecosystem.

The changes include: Entity-first event model — callbacks now live on channels, users, messages, etc. (more intuitive & discoverable); Strongly typed event payloads — no more manual parsing of generic events; Decoupled join/connect lifecycle — clearer control over membership vs message streaming; Improved messaging APIs — simplified sendText + powerful MessageDraft for rich content; Better read receipts & reactions — scalable, per-user updates + aggregated reaction models; More expressive membership APIs — easier checks and retrieval without full fetches; Cleaner, more consistent APIs across SDKs (with room for idiomatic differences where it matters).

Docs: Kotlin, Swift, JavaScript, Unity, Unreal

Deliver built-in operational insights through your own UI while maintaining tenant isolation, branding control, and secure multi-tenant experiences for white-label and OEM platforms.

PubNub AI Enhanced Auto-Moderation

Introducing PubNub AI Enhanced Auto-Moderation: a native, serverless filter that scans every message inside your PubNub VPC before it publishes, blocking profanity, and spam in milliseconds. No model training, external APIs, or backend code required. Flip one toggle in BizOps Workspace to protect chats and meet safety mandates instantly.

Introducing PubNub MCP Server

The Model Context Protocol (MCP) Server is our open-source bridge between PubNub SDKs and leading AI coding assistants including Claude Code, Cursor & Windsurf (it will soon be added to OpenAI’s Codex and Visual Studio Code). Backed by PubNub’s unparalleled data-streaming network, it simplifies building fast, scalable apps. Your agent fetches live snippets, docs, and recipes right in the IDE, turning natural-language prompts into production-ready real-time code. Launch it with one command.
