Allows users to select Ollama as a provider from client settings.
Previously, Ollama was blocked with "Invalid provider" error even
though the UI supported it.
Fixes#652
Ollama is a local/self-hosted model that doesn't require API keys.
The SSRF protection was incorrectly blocking Ollama connections
when users provided a custom base URL without an API key.
Fixes#652
Add full Traditional Chinese support for Hong Kong/Taiwan users by
creating a zh-Hant dictionary and registering the locale across the
web app, metadata, and Electron desktop menu system.
This reverts commit e7c29fb410.
The PR introduced an IndexedDB error: 'Failed to execute transaction on IDBDatabase: The database connection is closing.'

- Clear modified state after autosave to avoid beforeunload prompts
- Disable confirmExit in draw.io configuration
- Set modified=false and keepmodified=false URL parameters

Fixes#633 - browser showing infinite loading spinner when accessing
the MCP server URL without the session parameter.
When users access http://localhost:6002 directly (without ?mcp=xxx),
the page now auto-redirects to the most recent active session instead
of showing "No session" with an infinite loading spinner.
Upgrade wrangler from 4.58.0 to ^4.60.0 to fix the command injection
vulnerability (CWE-78) in the --commit-hash parameter of wrangler pages
deploy command.
Fixes#627
* enhancement: Add URL format hint to Base URL field (#593)
Add dynamic provider-specific format examples to Base URL field labels to clarify expected URL format. Includes missing defaultBaseUrl values for providers.
* fix: Use generic example URL instead of OpenAI URL for fallback
* [Feature] Add VLM-based diagram validation
Add automatic VLM (Vision Language Model) validation after display_diagram
tool execution. The system captures a screenshot of the rendered diagram,
sends it to a VLM for visual analysis, and uses feedback to improve
diagram quality through the existing retry mechanism.
Changes:
- Add /api/validate-diagram endpoint for VLM validation
- Add diagram-validator.ts for client-side validation orchestration
- Add validation-prompts.ts for VLM system prompts
- Add ValidationCard component to display validation status in chat
- Add PNG capture functionality to diagram context
- Integrate validation into tool handlers with retry support (max 3)
- Add "Improve with Suggestions" button for manual regeneration
- Add settings toggle to enable/disable VLM validation
- Add getValidationModel() helper in ai-providers.ts
* refactor(validation): use AI SDK structured outputs and address review feedback
- Replace generateText + manual JSON parsing with generateObject and Zod schema
for type-safe structured validation output
- Use AbortSignal.timeout() instead of Promise.race for cleaner timeout handling
- Add timeout validation with minimum 1000ms to handle malformed env values
- Remove unused xml parameter from validateRenderedDiagram API
- Remove parseValidationResponse function (now handled by schema)
- Clear validationStates on session switch and new chat to prevent memory leak
- Update 100ms render delay comment to clarify best-effort heuristic
- Remove unused useEffect import from ValidationCard
- Fix optional chaining lint warning in ValidationCard
- Add unit tests for formatValidationFeedback function
* refactor(validation): use AI SDK experimental_useObject hook instead of raw fetch
- Change API endpoint from generateObject to streamObject for useObject compatibility
- Create useValidateDiagram hook using AI SDK's experimental_useObject for reactive validation
- Update useDiagramToolHandlers to accept validation function as parameter
- Update chat-panel to use new useValidateDiagram hook
- Remove validateRenderedDiagram function from lib/diagram-validator.ts (now in hook)
- Export ValidationResultSchema from API route for client-side use
* fix(validation): extract schema to shared file for client/server compatibility
Move ValidationResultSchema to lib/validation-schema.ts to avoid importing
server-side modules (ai-providers) into client-side code. This fixes the
Turbopack build error caused by the hook importing from the API route.
* fix(validation): use 'Valid' instead of 'Complete' for validation success
Change ValidationCard success label from 'Complete' to 'Valid' to avoid
conflicting with ToolCallCard's 'Complete' badge in E2E tests. This fixes
the diagram-generation E2E test that expects a specific count of 'Complete'
badges.
* fix(validation): add aria-hidden to icons to prevent duplicate ID warning
* fix: improve VLM validation with bug fixes and i18n
- Fix race condition in pendingValidationRef (reject previous pending validation)
- Fix response format consistency (use streaming for all responses)
- Remove dead code (unused lastRequestRef and ValidationRequest interface)
- Consolidate duplicate types (re-export from validation-schema.ts)
- Add 'success_with_warnings' status for valid diagrams with warnings
- Fix tool card auto-collapse (only collapse once, respect user toggle)
- Set VLM validation default to disabled
- Add i18n support for diagram validation settings (en/zh/ja)
- Mark feature as experimental in settings UI
* fix: resolve TypeScript errors in electron-standalone
- Add forwardRef support to ChatInput component with ChatInputRef type
- Copy electron.d.ts to electron-standalone/electron folder
- Exclude electron-standalone from root tsconfig type checking
* fix: return empty string for valid result with no issues in formatValidationFeedback
* feat(i18n): add validation strings for ValidationCard component
- Add validation section to en.json, zh.json, ja.json dictionaries
- Update ValidationCard to use useDictionary hook
- Replace all hardcoded English strings with i18n keys

* fix(quota): bypass quota for users with Bedrock credentials
The hasOwnApiKey check only looked for x-ai-api-key header, but Bedrock
users provide AWS credentials via x-aws-access-key-id instead. This
caused Bedrock users with their own credentials to still be subject to
quota limits.
* fix(quota): also bypass quota for Vertex AI users
* style: auto-format with Biome

cpSync with dereference:true does NOT convert symlinks to files.
This implements a custom copyDereferenced function that:
- Detects symlinks using lstatSync
- Follows them using statSync
- Copies actual file/directory content instead of symlink
Fixes macOS arm64 codesign failure with electron-builder 26.4.0
which now does ad-hoc signing and runs codesign --verify.
- Replace forwardRef/useImperativeHandle with prop-based focus control
- Add shouldFocus and onFocused props to ChatInput
- Use useEffect with setTimeout for proper cleanup
- Removes unnecessary complexity while maintaining same functionality
* fix: allow private URLs by default for reverse proxy setups
Fixes#588 - Users with reverse proxy setups (e.g., Antigravity tools)
were getting "Invalid base URL" errors due to SSRF protection blocking
private/internal URLs.
Changes:
- Add ALLOW_PRIVATE_URLS env var (defaults to true)
- Set to "false" to enable strict SSRF protection if needed
* refactor: extract isPrivateUrl to shared utility
When the LLM generates edit_diagram tool calls, it sometimes produces
inconsistent quote escaping in XML attributes within JSON strings.
For example: y="-20\" instead of y=\"-20\"
This causes JSON parsing to fail, and jsonrepair cannot fix this pattern.
Added pre-processing regex to detect and fix cases where the opening
quote is unescaped but the closing quote is escaped in attribute values.
After create_new_diagram, edit_diagram would fail with "You must call
get_diagram first" because lastGetDiagramTime was never set (remained 0
from session init). This fix sets lastGetDiagramTime after creating a
diagram, allowing immediate edits.
Fixes#534, Fixes#589

Refactored all 11 providers to use the resolveBaseURL() utility function
instead of inline ternary expressions. This ensures:
1. The security fix is centralized in one testable function
2. Unit tests actually validate the production code path
3. Future changes only need to modify one location
Providers refactored: openai, anthropic, google, azure, openrouter,
deepseek, siliconflow, sglang, gateway, doubao, modelscope
