Kameleoon-client-python

Features
* Added new optional parameters `negative` and `metadata` to the [`track_conversion`](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk#track_conversion) method.
* Added new optional parameter `metadata` to the [`Conversion`](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk#conversion) data constructor.
* Added new configuration parameter `network_domain` to [`KameleoonClientConfig`](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk/#create) and the [configuration](https://developers.kameleoon.com/python-sdk.html#additional-configuration) file. This parameter allows specifying a custom domain for all outgoing network requests.

Features
* Added support for Contextual Bandit evaluations. Calling [`get_remote_visitor_data`](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk#get_remote_visitor_data) with the `cbs=True` flag is required for this feature to function correctly. Platform-wide release expected in March 2025.

Features
* Added SDK support for **Mutually Exclusive Groups**. When feature flags are grouped into a **Mutually Exclusive Group**, only one flag in the group will be evaluated at a time. All other flags in the group will automatically return their default variation.

Features
* Added SDK support for **holdout experiments**. Visitors assigned to a holdout experiment are excluded from all other rollouts and experiments, and consistently receive the default variation. For visitors not in a holdout experiment, the standard evaluation process applies, allowing them to be evaluated for all feature flags as usual. Platform-wide release expected in February 2025.

Features
* Added support for **simulated** variations.
* Added the [`set_forced_variation()`](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk#set_forced_variation) method. This method allows explicitly setting a forced variation for a visitor, which will be applied during experiment evaluation.

Bug fixes
* Resolved an issue where the validation of [top-level domains](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk/#additional-configuration) for `localhost` resulted in incorrect failures. The SDK now accepts the provided domain without modification if it is deemed invalid and logs an [error](https://developers.kameleoon.com/feature-management-and-experimentation/web-sdks/python-sdk/#log-levels) to notify you of any issues with the specified domain.
