Changed

• ExportApi.export_signals_v2 parameter renames to match the wire contract on ExportSignalsV2Request:
  • signal → signals
  • resource_name → entities
  • tag → tags
• ExportApi.export_signals_v2 now always returns a DataFrame. Previously it returned a pd.Series for single-time-series results; call .squeeze() yourself if you relied on that.
• ExportApi.export_signals_v2 rows are a (name, time) MultiIndex whenever entities or tags is set, regardless of count. Previously a single-entity call returned a flat DatetimeIndex.
• ExportApi.export_signals_v2 drops all-NaN rows from the result.
• ExportApi.export_signals_v2 no longer accepts Column as a signal input; pass a str label or a DerivedSignal.
• start_time and end_time are required on export_signals_v2 and run_export_signals_v2 (previously optional).
• entities and tags on run_export_signals_v2 are typed as Sequence[str] instead of list[str].

Added

• New example script exabel.examples.entity_search_example showing how to resolve company resource names via client.entity_api.search — by Bloomberg ticker, by (MIC, ticker), and by free-text search.

Removed

• ExportApi.signal_query_v2 and ExportApi.run_signal_query_v2. Use export_signals_v2 and run_export_signals_v2 instead.

Added

• New v2 export methods in ExportApi: export_signals_v2,
  run_export_signals_v2, and export_signals_v2_bytes.
• New CLI script exabel.scripts.export_signals_v2 that runs a v2 signal
  export and writes the raw server response to disk. Output format is
  selected by the --filename extension (.csv, .xlsx, .json,
  .feather, .parquet).
• New optional dependency group export. Install with
  pip install 'exabel[export]'.

Changed

• pyarrow is required for export_signals_v2 and run_export_signals_v2.

Deprecated

• signal_query_v2 and run_signal_query_v2 are deprecated; use
  export_signals_v2 and run_export_signals_v2 instead.
• run_query_bytes with file_format="pickle" is deprecated.

Removed

• The v2 export endpoint no longer accepts output_format="pickle".

Added

• v2 export signals API in ExportApi, with support for DerivedSignal and
  Column arguments in signal_query() / batched_signal_query().

Changed

• Prepared timestamp handling for pandas 2.x: new resolution-agnostic datetime
  conversion helpers used by TimeSeriesApi and related data classes.
• Removed usage of pandas APIs deprecated in 2.x across ExportApi,
  FileTimeSeriesParser, and the check_company_identifiers_in_csv script.
• Internal code cleanups from expanded linter rule sets; no behavioral changes.

Full Changelog: v8.0.0...v8.1.0

Added

• Added CalendarApi.get_company_calendar() to retrieve fiscal calendars for a company.
• Added support for DerivedSignal objects in ExportApi.signal_query() and ExportApi.batched_signal_query().

Breaking changes

• Renamed the Python package from exabel-data-sdk to exabel.
• Removed legacy setup.py; the project now uses pyproject.toml exclusively.
• Removed deprecated parameters from bulk_import(): resources_batches, threads_for_import_func, threads_for_insert_func, insert_func.
• Removed deprecated parameter threads_for_import from TimeSeriesApi.import_time_series().
• Removed username/password authentication for the Export API (deprecated in 7.0.0).

Changed

• Upgraded protobuf stubs.
• Refactored core data classes (DataSet, Entity, EntityType, Relationship, RelationshipType) to use Python dataclasses.
• Migrated SDK tests from unittest to pytest.

• Removed support for Python 3.9 (EOL)

Deprecated

• Support for username/password authentication when accessing the Export API is now deprecated. This authentication method will be removed in a future release. Use access token instead.
