Address review feedback: extract the repeated clipboard availability check +
writeText + error handling pattern into a shared copyToClipboard() utility in
@copilotkit/shared. All 9 call sites across angular, react-core, and react-ui
now use the shared utility instead of duplicating the same code block.
The shared visitedRefs Set was mutated in place, so when two sibling
properties referenced the same $def (e.g. billing and shipping both
referencing Address), the second resolution was incorrectly flagged as
circular. Clone the set before recursing so each branch has its own
ancestry path. Added regression test that fails without this fix.
Recursive JSON schemas that reference themselves via $ref would cause
infinite recursion and stack overflow. This adds a visited set that
tracks which $ref paths have been seen during resolution. When a cycle
is detected, it breaks with z.any() and logs a console.warn so users
get feedback. Also adds console.warn for the generic z.any() fallback
on unsupported schema types.
Adds tests for circular refs, non-circular $ref resolution, anyOf with
$ref variants, integer type, null type, and unsupported type warning.
- Replace custom { name, props } schema format with spec-aligned inline
catalog format (allOf + properties) so the LLM sees the same flat
structure it must produce — eliminates "props" nesting confusion.
- Restructure generation prompts: inline literal values are the default,
path binding is a narrow schema-driven exception for form inputs.
- Export InlineCatalogSchema type from a2ui-renderer.
LLMs sometimes use path bindings (e.g. {"path": "/chartData"}) on
component properties that only accept literal values, causing silent
render failures. The new guideline tells the LLM to check the schema's
anyOf type before using path bindings.
When users pass the boolean shorthand `debug: true`, verbose previously
defaulted to true, logging full event payloads including user messages,
tool args, and state snapshots. Now defaults to false — users must
explicitly opt in with `debug: { verbose: true }`.
## Summary
- Handle `anyOf`, `oneOf`, `$ref`, and null type entries when converting
JSON schema to Zod schemas
- Prevents runtime errors when LLM tool parameters use union types or
nullable fields

- Fix clone() dropping debug config on ProxiedCopilotRuntimeAgent
- Pass raw DebugConfig to agents instead of collapsing to boolean
- Clamp verbose to false when enabled is false
- Fix pino-pretty log format in docs (parentheses, timestamps, levels)
- Add loggedEventCount to doc example
- Fix "Agent run started/finished" → actual log messages in arch docs

Replace @a2ui/lit with @a2ui/web_core 0.9, introduce createCatalog() API for
custom component catalogs, add basic (18 components) and minimal (5 components)
built-in catalogs, CSS variable theming for dark mode, eliminate XSS vector
(dangerouslySetInnerHTML removed from Text component).
Reverts the copy-dts.mjs approach from #3612 in favor of typesVersions
which is the standard Node/TS mechanism for resolving subpath types
under legacy moduleResolution: "node".
- New docs/(root)/migration-guides/ section with migrate-to-v2, migrate-attachments,
migrate-to-1.10.X, migrate-to-1.8.2
- Troubleshooting now only contains error-debugging, observability-connectors, common-issues
- Update all @deprecated JSDoc URLs from /troubleshooting/ to /migration-guides/
- Update doc cross-links (multimodal-attachments page, snippet import)
- Move snippet to snippets/shared/migration-guides/
- Set minimum version to v1.56.0 (was vX.Y.Z placeholder)
- Restore console.error as safety net in processFiles catch blocks (errors no longer
silently vanish when onUploadFailed callback is not provided)
- Add try/catch to useBlobUrl atob() — gracefully handles malformed base64 instead of
crashing the component tree
- Fix DocumentLightboxContent: use blobUrl instead of undefined src variable
- Add .catch() to View Transition API transition.finished promise
- Codemod: preserve actual imageUploadsEnabled value (false, dynamic expressions)
instead of hardcoding true — adds 3 new test cases (18 total)
- Replace all placeholder @deprecated versions (v1.x.0) with @since 1.56.0
- Add missing @since to ImageRenderer, ImageRendererProps, AIMessage.image tags
Attachment queue & previews:
- Image lightbox with View Transition API morph animation
- Video lightbox with native controls and play button overlay
- Document lightbox (PDF via blob URL, text inline, info card fallback)
- Drop zone overlay with upload icon
- Filename preservation via InputContent metadata
- Proper video thumbnail sizing and play/pause indicator
- Fix attachment queue positioning (max-w-3xl constraint)
- Padding between X button and content for audio/document cards
- Document filenames wrap instead of truncating
Attachments config:
- onUploadFailed callback for validation/upload errors (file-too-large, invalid-type, upload-failed)
- onUpload accepts sync or async returns
- AttachmentUploadResult discriminated union with explicit interfaces
- Metadata field on Attachment and onUpload return type
AG-UI version bump:
- Bump @ag-ui/client, @ag-ui/core, @ag-ui/encoder, @ag-ui/proto to 0.0.51
- Remove process.env Vite workaround (fixed upstream in 0.0.51)
Deprecation lifecycle:
- @deprecated JSDoc on all legacy image upload APIs
- ImageRenderer, ImageRendererProps, ImageUpload type, imageUploadsEnabled prop,
inputFileAccept prop, ImageRenderer prop, AIMessage.image, ImageData
- Codemod at codemods/migrate-attachments.ts (15 tests)
- Migration guide updated with codemod instructions and new type shapes
Docs:
- New guide: docs/(root)/multimodal-attachments.mdx
- Updated migration guide with onUpload return type, metadata, codemod section
- Cross-links from prebuilt-components and migration guide
- Label change: "Add photos or files" → "Add attachments"
Tests:
- CopilotChat.attachments.test.tsx — 5 tests for onUploadFailed
- migrate-attachments codemod — 15 tests
Re-export AG-UI multimodal input types (InputContent, TextInputPart, ImageInputPart,
AudioInputPart, VideoInputPart, DocumentInputPart, InputContentSource, etc.) from
@copilotkit/shared. UserMessage is now a plain pass-through of agui.UserMessage,
removing the CopilotKit-specific image?: ImageData extension. ImageData is kept with
@deprecated for backward compatibility with AIMessage.image.
Copies .d.cts → .d.ts after each tsdown build so consumers on
moduleResolution "node" (e.g. DocuSign) can resolve types without
changing their tsconfig. Also points the "types" field back to .d.ts.

All @copilotkit/* packages were missing type declarations in their exports
map. This meant TypeScript couldn't resolve types for subpath imports like
@copilotkit/react-core/v2 without manual tsconfig paths workarounds
pointing to dist .d.ts files (which no longer exist after the tsup to
tsdown migration).
Uses nested conditional exports to map .d.mts for ESM and .d.cts for CJS
consumers, satisfying both attw and TypeScript module resolution under
nodenext and bundler modes.

@copilotkit/shared was doing `export * from "@copilotkit/license-verifier"`,
which pulled the entire license-verifier bundle (including Node's `crypto`)
into any client-side consumer. This caused "Module not found: Can't resolve
'crypto'" errors for users bundling @copilotkit/react-core for the browser.
Now shared only re-exports types (erased at compile time) and a client-safe
`createLicenseContextValue` inlined without crypto. Runtime imports
`createLicenseChecker` and `getLicenseWarningHeader` directly from
`@copilotkit/license-verifier`.

The previous publish workflow released 1.55.0-next.8 to npm but the
post-release commit failed to push to main (blocked by branch
protection). This applies the version bumps and pre.json updates that
the workflow would have committed, unblocking future releases.
