<Update label="6.2.0" description="2026-07-27">

    The changes below are relative to Atoti Python SDK
    [0.9.16](https://docs.activeviam.com/engine/python-sdk/0.9/changelog#0-9-16).
  </Note>

  ### Summary

  * [Atoti Intelligence](#atoti-intelligence)
  * [Limits plugin](#limits-plugin)
  * [Query History](#query-history)
  * [Upgraded dependencies](#upgraded-dependencies)
  * [Safer data loading default](#safer-data-loading-default)

  ### New features

  #### Atoti Intelligence

  Atoti Intelligence has been stabilized:

  * [`atoti_ai.Chat`](./api/atoti_ai.Chat) answers natural-language questions about the data, powering the [AI chat in Atoti UI](https://docs.activeviam.com/atoti-intelligence/6.2/user-guide/chat).
    Fill in the new [`atoti.Dimension.description`](./api/atoti.Dimension.description) to give it more context about the data model.
  * [`atoti_ai.AutoExplain`](./api/atoti_ai.AutoExplain) surfaces the hierarchies and members that best explain a measure's variation, speeding up root-cause analysis.
  * [`AggregateProviders.recommender`](./api/atoti.aggregate_provider.AggregateProviders.recommender) analyzes a [`Cube`](./api/atoti.Cube)'s query traffic and recommends the most impactful [`AggregateProvider`](./api/atoti.aggregate_provider.AggregateProvider) coverage for it.

  #### Limits plugin

  The [`atoti-limits`](./api/atoti_limits) plugin connects an Atoti session to a Limits server and adds the Limits [`app extension`](./api/atoti.config.SessionConfig#atoti.SessionConfig.app_extensions) to Atoti UI.

  #### Query History

  When the [`observability plugin`](./api/atoti_observability) is enabled and [`atoti.SessionConfig.user_content_storage`](./api/atoti.config.SessionConfig#atoti.SessionConfig.user_content_storage) is not `None`, the history of executed queries is recorded and accessible in Admin UI's **Query history** tab.

  ### Improvements

  #### Upgraded dependencies

  * Bumped the minimum required Python version to [3.12](https://docs.python.org/3/whatsnew/3.12.html) as per [NEP 29](https://numpy.org/neps/nep-0029-deprecation_policy.html#support-table).
  * Bumped the minimum required Pandas version to [3.0.3](https://pandas.pydata.org/pandas-docs/version/3.0/whatsnew/v3.0.3.html).
  * Aligned Atoti Python SDK's version with Atoti Server.
    Going forward, each `6.2.x` Python SDK release depends on the matching `6.2.x` Server release, making compatibility obvious at a glance.

  #### Safer data loading default

  [`atoti.Table.load(error_handling)`](./api/atoti.Table.load#atoti.Table.load.error_handling) defaults to `"fail"` instead of `"log"`, so loading errors surface immediately instead of being silently logged.
