2026-01-11 db 2.0.0

This release makes the database schema fully consistent and thereby improves UX, integrity, and enables long-term stability.

If you have data in removed registries you’ll see a warning that your data gets exported to parquet files. You can import these parquet files into the Record registry under an Experiment type without losing of functionality.

⚠️ After migrating databases to v2 via lamin migrate deploy lamindb package installations with v1 will raise errors. This is the last planned database migration that breaks older clients.

All instances connected to LaminHub have been migrated and there is no need to act.

If you are an admin of a self-managed instance, please migrate your database with lamin migrate deploy.

For details see the Compatibility Matrix and the source code.

⚠️ For laminr and nf-lamin users

For laminr users with an auto-managed reticulate environment, please run this:

reticulate::py_require("lamindb>=2.0.1") # DO THIS FIRST
ln <- laminr::import_module("lamindb")

For nf-lamin users, please upgrade to 0.3.0.

Features:

  • ✨ Track shell scripts PR @falexwolf

  • ✨ Enable managing workflows by decorating functions with @ln.flow() and @ln.step() and deprecate @ln.tracked() PR @falexwolf

Architecture:

  • 🏗️ For more robustness and to convey the field’s special nature in the API and the database schema, replace Feature.dtype with Feature._dtype_str to now hold a serialization that links object types (Record + ULabel) based on their uid instead of their name and type hierarchy PR @falexwolf

UX:

  • 🚸 Add feature.dtype_as_object PR @sunnyosun

  • 🚸 Add description argument to Transform.from_git() PR @falexwolf

  • 🚸 Allow passing _key_is_virtual on Artifact creation PR @Koncopd

  • 🚸 Raise SystemExit upon InstanceNotFound only from CLI PR @falexwolf

  • 🚸 Raise error for init or import issues in lamin io snapshot PR @Zethson

  • 🚸 Do not track inputs when calling collection.artifacts.all() PR @Koncopd

  • 🚸 Raise a clear error if calling CanCurate and similar registry class methods on objects PR @falexwolf

  • 🚸 Sort features in describe() PR @falexwolf

  • 🗃️ Migrate most auxiliary fields to SQL columns PR @falexwolf

  • 🗃️ Simplify Transform PR @falexwolf

  • 🗃️ Rename IsVersioned.version to IsVersioned.version_tag, Transform.type to Transform.kind, FeatureValue to JsonValue, BaseBlock.type to BaseBlock.kind, delete Transform._template and Run._logfile PR @falexwolf

  • 🗃️ Rename Artifact._subsequent_runs to Artifact.recreating_runs and Run._recreated_artifacts to Run.recreated_artifacts PR @falexwolf

  • 🗃️ Rename SQLRecord._branch_code to SQLRecord.branch_id and remove feature_ref_is_name and label_ref_is_name fields from link models PR @falexwolf

  • 🗃️ Rename Artifact.feature_sets to Artifact.schemas PR @falexwolf

  • 🗃️ Migrate the Feature and Schema database tables to LaminDB v2 PR @falexwolf

  • 🗃️ Swap accessor names for SchemaComponent links, consistent ManyToMany field names for RecordRecord links PR @falexwolf
