[dependabot]

Bumps @notionhq/client from 5.9.0 to 5.11.1.

Release notes

Sourced from @​notionhq/client's releases.

v5.11.1

What's Changed

• Sync api-endpoints: unsupported block type, update page docstring tweak by @​ksinder in makenotion/notion-sdk-js#672
  • New string field unsupported[block_type] in UnsupportedBlockObjectResponse to provide a hint on what an underlying unsupported block type is
  • Minor TSDoc change for updatePage endpoint: remove "properties" suffix from API name; just "Update page" now.
    • This reflects the fact that the endpoint does more than just updating properties/schema

PR Review: @notionhq/client Dependency Update

Summary

This is a Dependabot-managed minor version update for the Notion SDK from 5.9.0 → 5.11.1. The changes are clean, minimal, and limited to dependency files.

✅ Code Quality & Best Practices

• Minimal changes: Only package.json and package-lock.json modified
• Lint checks passing: CI confirms no TypeScript or linting errors introduced
• Proper dependency management: Using npm with lock file for reproducible builds

🔍 Compatibility Analysis

I reviewed the release notes and code usage across the codebase. The upgrade is safe to merge:

Key Changes in v5.10.0-5.11.1:

• ✅ Automatic retry support with exponential backoff (v5.10.0) - This is beneficial and improves API reliability
• ✅ New markdown endpoints (v5.11.0) - Additive, won't affect existing code
• ✅ New unsupported[block_type] field (v5.11.1) - Additive, optional
• ✅ Unknown parameter warnings (v5.11.0) - Non-breaking, may surface warnings only

Code Coverage Check:
The codebase uses these Notion SDK features, all of which remain compatible:

• ✓ Client initialization
• ✓ Pages API (create, update, retrieve)
• ✓ Comments API
• ✓ Blocks API (list, append, delete)
• ✓ File uploads API
• ✓ Type helpers (isFullPage, isFullBlock, isFullComment)

No transcription blocks or other specialized block types are currently handled in the code, so the block response shape update doesn't impact functionality.

🚀 Performance

The new automatic retry support could provide improved reliability during transient Notion API issues—this is a positive change.

🔐 Security

• No breaking changes to authentication
• Updated dependency has no reported security vulnerabilities
• NOTION_TOKEN usage remains secure

✔️ Test Coverage

• Lint check ✅ PASSED
• CodeQL ✅ NEUTRAL (no new issues)
• Vercel preview builds successfully

Recommendation

Ready to merge ✅ This is a straightforward, well-tested dependency update with no breaking changes and beneficial reliability improvements.
