Changelog

All notable RCIP changes are documented here.

2.0.5

• Replace the GitHub and npm READMEs with concise, evidence-led positioning: explicit operations, app-controlled exposure, framework-neutral core, and integration available today.
• Publish the synthetic dispatch workflow benchmark and its limitations; keep historical experimental results available without presenting them as separate products.
• Clarify data minimization, predictable execution, and the boundaries of application policy and server authorization.
• Update documentation discovery metadata and the current version. Runtime behavior, public APIs, protocol 1.0, and dependencies are unchanged from 2.0.4.

2.0.4

• Add optional client.preflight for 1–16 independent proposals checked concurrently without executing handlers or creating confirmation tickets.
• Report ready, blocked, or confirmation-required outcomes with validation details, cancellation and discovery-revision freshness. Host policy receives an optional evaluation phase.
• Preserve protocol 1.0, existing client adapters and direct invocation; every invocation still checks current state. Preflight is advisory, not a reservation, authorization token or transaction.
• Recheck binding, availability and context after asynchronous readiness evaluation and synchronous host event observers.
• Add a readiness control to the pilot workbench, composed browser coverage and integration guidance.
• Refresh affected dependency resolutions to clear the release dependency audit, retaining the reviewed Rollup toolchain.
• Stabilize packed consumer verification with the lockfile's Rollup version and explicit build dependencies, including after Vite preview changes process environment.

The maintainer selected 2.0.4 for this backwards-compatible, optional API addition.

2.0.3

• Add a standalone React/TypeScript starter using the public npm package, with capability discovery, live reads, confirmed writes, validation, and cancellation.
• Expand agentic UI, in-app agent, frontend tool, and browser-use discovery metadata and integration guidance.
• Publish a compact llms.txt documentation map and a captioned demo walkthrough with source-only starter downloads.
• Keep runtime behavior, public APIs, protocol 1.0, and the existing health-monitoring expiry unchanged.

2.0.2

• Expand React UI-agent and tool-calling discovery metadata, use cases, and MCP/WebMCP positioning while making adapter boundaries explicit.
• Add shared local and GitHub Actions commands for registry availability and fresh published-package regression across React 18.2, 18.3, and 19.1.
• Verify the exact registry version after each publish, including browser behavior and live documentation/demo checks.
• Add an explicitly bounded seven-day availability schedule with daily regression, automatic expiry, and no persistent Actions caches or artifact uploads.
• Keep runtime behavior, public APIs, and protocol 1.0 unchanged.

2.0.1

• Prevent duplicate invocation IDs during asynchronous policy and pending confirmation.
• Reject binding, availability, and context changes before execution; capture confirmation input independently of caller mutation.
• Release expired/cancelled confirmations and protect catalog/snapshot metadata from mutation.
• Update React bindings only after committed renders and document cancellation, retry, schema, SSR, and lifecycle guarantees.
• Rename the expansion to React Capability Interface Protocol without changing package/API names or protocol 1.0.
• Publish searchable documentation, API contracts, measured entrypoints, a Finance case study, and a browser-only interactive demo.
• Add concurrency, confirmation, lifecycle, SSR/hydration, and static-site browser verification; repair secret-history scanning and patch build dependencies.

2.0.0

• Promoted the accepted 2.0.0-beta.5 release candidate to stable without runtime or public API changes.
• RCIP 2 provides protocol 1.0 semantic scopes and capabilities, a framework-neutral runtime, React bindings, packaged Assist and Explorer surfaces, confirmation and cancellation controls, consumer-owned input pipelines, and React 18/19 compatibility.
• This major is intentionally incompatible with RCIP 1.x. See the migration guide.

2.0.0-beta.5

• Changed disabled voice input so single click or Space reports that voice is unavailable without opening chat or invoking a microphone or provider.
• Kept double-click, long-press, and Enter as direct ways to open chat.

2.0.0-beta.4

• Removed the in-chat example prompt section so Assist opens directly into a focused conversation and composer experience.
• Removed the corresponding examplePrompts UI prop during the v2 beta.

2.0.0-beta.3

• Rebuilt the packaged Assist UI as a polished, responsive conversation panel with keyboard/touch alternatives, reduced-motion support, accessible status announcements, and automatic light/dark presentation.
• Changed the collapsed dot to single-click simulated listening and double-click chat opening. The simulation captures no audio, calls no provider, and invokes no capability.
• Added consumer-owned voice adapters and ordered audio/text input processors for capture → transcription → refinement → Assist pipelines.
• Fixed dragged panel state so closing restores the launcher and the next panel opening to the original configured anchor.
• Removed capability disclosure from Assist; the separate read-only Explorer remains the capability inspection surface.
• Expanded package and repository documentation with a complete integration flow, input-pipeline guide, accessibility behavior, theming, and security boundaries.
• Added browser coverage for click arbitration, input processing, keyboard controls, drag reset, and the updated responsive UI.

2.0.0-beta.2

• Added optional provider-neutral capability usage guidance and schema-valid examples to definitions and discovery snapshots.
• Added the packaged @binaried/rcip/assist dot, draggable floating panel, headless hook, explicit interactive/read-only modes, host confirmation, cancellation, bounded sequential batches, and summarize-only phase.
• Added React 18/19 packed-consumer coverage for Assist and its styles export.
• Reworked the standalone pilot to use the packaged Assist with deterministic behavior and an optional consumer-owned server-side provider adapter.
• Moved the standalone pilot default from port 4000 to temporary port 4176.

2.0.0-beta.1

• Pinned the npm release toolchain and regenerated the lockfile with npm 11 so clean CI installs use the same dependency resolution as release preparation.
• No public API or runtime behavior changed from 2.0.0-beta.0.

2.0.0-beta.0

• Allow stable lower-camel capability identifier segments such as polls.prepareCreate.

• Replaced the component/action registry with protocol 1.0 semantic scopes, capabilities, context, and strict JSON contracts.

• Added the framework-neutral runtime with discovery, availability, policy, confirmation, cancellation, structured outcomes, and redacted lifecycle events.

• Added React provider, context, binding, client, and snapshot hooks.

• Added the optional read-only capability explorer.

• Added ESM, CommonJS, TypeScript declaration, React 18/19, and packed-consumer validation.

• Added Apache-2.0 licensing and trusted npm release automation.

This beta is intentionally incompatible with RCIP 1.x. See the migration guide.
