Storybook 8.1.10 Version

[francomoron]

Description

We are currently running Storybook 8.1.10 and the CLI is prompting an upgrade to 10.3.5, which spans 2 major versions. Before proceeding, we need to assess the potential breaking changes and migration effort involved.

Current behavior

• Storybook version: 8.1.10
• Suggested version: 10.3.5
• The upgrade prompt appears on every storybook dev run

Concerns

• Possible breaking changes in .storybook/main.js configuration
• Addon compatibility with v10
• Deprecated builders or framework integrations
• No clear migration path documented for skipping v9 entirely

Steps to reproduce

1. Run npx storybook dev
2. Upgrade prompt appears suggesting v10.3.5
3. Running npx storybook@latest upgrade may break existing configuration

Expected behavior

A safe, documented migration path from v8 to v10, or confirmation that skipping v9 is supported.

Environment

• Storybook: 8.1.10
• Framework: react-vite
• Node version: v22.18.0
• OS: MacOs
