v29.0.0 (2025-03-26)¶

New Features¶

Added tools for comparing schemas in the diff module. These can be run from the command line with felis diff. (DM-46130)
Added column grouping functionality to the data model. Column groups are sets of related columns that, in addition to the standard object attributes, may have an ivoa:ucd. Information on column groups was also added to the User Guide. (DM-48427)

Added Python 3.13 to supported versions. No code changes were required. (DM-47900)

Removed the apply_schema_to_tables flag on the MetaDataBuilder which creates SQLAlchemy MetaData from a Felis Schema. This was a redundant variable as enabling the apply_schema_to_metadata flag already correctly associated the metadata to the schema. (DM-47256)
Removed the tap module, which was replaced by tap_schema. The init-tap command was removed from the CLI and replaced with init-tap-schema. (DM-48616)

Added a new tap_schema module designed to deprecate and eventually replace the tap module. This module provides utilities for translating a Felis schema into a TAP_SCHEMA representation. The command felis load-tap-schema can be used to activate this functionality. (DM-45263)
Added a check to the data model which ensures that all constraint names are unique within the schema. TAP_SCHEMA uses these names as primary keys in its keys table, so they cannot be duplicated. (DM-45623)
Added automatic ID generation for objects in Felis schemas when the --id-generation flag is included on the command line. This is supported for the create and validate commands. Also added a Schema validator function that checks if index names are unique. (DM-45938)

Fixed a bug where the error locations on constraint objects during validation were reported incorrectly. This was accomplished by replacing the create_constraints() function with a Pydantic discriminated union. (DM-46002)

Added option for setting TAP_SCHEMA index in load-tap command. (DM-43683)
Added option for creating a schema’s database if it does not exist when running the create command. (DM-43108)
Added setting of log level and output file in the CLI (DM-43040)
Created a validator that will look for redundant datatype specifications. This is activated from the command line with the --check-redundant--datatypes flag. (DM-41247)

Added a new metadata module for generating SQLAlchemy MetaData from a schema. This replaces the old module that was used in the create command for initializing the database. (DM-43079)
Made columns nullable by default in the Pydantic data model. (DM-43753)
Refactored the tap module to use the Pydantic data model. (DM-42935)
Moved database utilities into a separate package and refactored them. (DM-44721)

Removed JSON-LD commands from the CLI and removed pyld from requirements.txt. (DM-43688)
Removed outdated modules. (DM-43597)
