# Sub-issues, Blockers, and Smarter File Attachments

Tasks now support sub-issues and blocker relationships. Kairo can read and attach any file type without size limits. And the task board and list views got a thorough visual polish pass.

## What’s changed

#### New

- Sub-issues let you break any task into smaller pieces, with counts and parent breadcrumbs shown on cards
- Mark tasks as blocked by or blocking other tasks, with blocker indicators on cards and a full relations panel in task detail
- Create sub-tasks right inside the Create Task dialog before you even save the parent
- Kairo can now read files from your Drive directly, including PDFs, Word docs, spreadsheets, presentations, and more
- Attach Word, PowerPoint, Excel, OpenDocument, Markdown, CSV, and code files to Kairo conversations, not just images and PDFs

#### Improved

- File attachments in Kairo upload to Drive first, removing the size limit for anything you share with Kairo
- Task board columns and cards have layered shadows, smoother hover effects, and refined label and due date styles
- Task list view has a redesigned column header, row hover shadow, and inline sub-task count and parent breadcrumb
- Task detail panel opens and closes faster
