No, v3 is a release with breaking changes:
This release includes several breaking changes; read the full migration guide here. It’s worth mentioning that many of the breaking changes are updates to API endpoints and only affect third-party tools that integrate with Immich’s API. For the vast majority of users, updating works exactly as it always has.

That’s why the major version was increased, it implies breaking changes in semantic versioning, which Immich is doing since v2 apparently:
Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes
- MINOR version when you add functionality in a backward compatible manner
- PATCH version when you make backward compatible bug fixes


Oh I see. You mean like v3.0.1 will be stable, and v3.1.0 will be stable. Yeah that’s true. But v3 (as in v3.0.0) is breaking. At least that’s how I have always seen the terms used.
