Here’s a clear and friendly upgrade notice you can add to the release notes or README:

You can upgrade directly from v0.1.5 to v0.2.0 without any intermediate steps.

Please note the following breaking changes related to authentication:

Previously created access tokens are no longer valid and must be regenerated.
The old root account and password are removed.
The system now includes a built-in admin account:
- Username: admin
- Password: admin@bichon

After logging in, you can update the username, password, avatar, and profile information in Settings → Profile.

We strongly recommend changing the default credentials immediately after upgrading.
