1.26.26
Highlights
- Clark now stays smart over long sessions. Previously, Clark would lose context as conversations grew. Now Clark maintains a working memory—automatically retaining what was accomplished, key decisions, and constraints discovered.
- API generation is significantly faster and more accurate. We rewrote core parts of how Clark understands and generates APIs—full support for control flow features, a completely rebuilt parameterized SQL system, and improved handling of API documentation. Fewer mistakes, faster results.
- Inference errors no longer block you. Intermittent Vertex/Bedrock errors are now handled gracefully—if you see one, just send another message and Clark will recover.
- Clark can search the web. Clark can now perform real-time web searches. This is especially useful for using third-party libraries and looking up documentation for integrations in real time.
New capabilities
- Embedded apps with two-way communication. Superblocks apps can now communicate with parent apps and vice versa. Ask Clark to set up the interface for properties and events.
- Windows local development. Powershell support—no WSL required.
Clark generation improvements
- Clark can now build file upload features (e.g., send a file to an AI model or upload to bucket storage)
- Clark can now build apps with profile switching
- Clark can now modify REST API body content types reliably
- Clark is better at targeted UI edits thanks to improved context about UI component layout
- Clark tests APIs faster
- Clark no longer hits timeouts when testing APIs
API generation
- Added support for all control flow features
- Rewrote parameterized SQL system—Clark can now always write parameterized SQL accurately and safely queries when parameterization isn’t possible
- Improved handling of API documentation and integration OpenAPI specs
- Fixed API transformation so Clark always sees user modifications
- Fixed missing bodyType field in REST API type declarations that caused TypeScript errors
- Added missing integration class declarations for 8 data sources (S3, MongoDB, GraphQL, and others)
- Prevented Clark from reading redundant JavaScript files in API directories
Chat experience
- Improved performance and reduced flickering for chats with many messages
- Chat no longer appears stuck thinking—now distinguishes between model thinking and time between tool calls
- Keyboard shortcuts for multichoice responses
- Fixed newlines not rendering correctly in AI-generated summaries
- Removed duplicate reconnection messages
Plan mode
- Plan mode always presents a new plan when you give feedback
- Clark has better context about targeted UI components and can make targeted edits more accurately
Reliability
- Edit mode loads reliably even after bad code generations, allowing Clark to fix issues
- Fixed chat crashes when clicking Clark’s interactive buttons (Build it, multiple choice) too quickly
- Fixed chat getting stuck centered on screen after generation
- Deployed app links now work correctly when opened in new tabs
- Syntax error indicator in top bar now clears after Clark fixes the issue
Versions & checkpoints
- Restore to any checkpoint from the Versions panel
- Restore to past checkpoint if you pause a generation midway
- Reset now works from the history panel even when unpinned
Other improvements
- Clone existing apps from the homepage
- Homepage search clears when entering folders
- Step navigation preserves previous run outputs
- Run Superblocks APIs locally without disabling browser local network access checks
- Changed “Think…” to “Starting development server” for clearer status during startup
