+## v1.18.2
+Released: 2024-11-13
+
+- IMPROVEMENT: Enhanced the flexibility of the [`ProphetModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) for tz-aware data (`tz_aware = True`). The `tz_seasonalities` argument has been reformatted to align with the structure of the existing `seasonalities` argument. For more details, refer to the [model section here](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet). Additionally, tz-aware support for `ProphetModel` has been added to [`AutoTuned`](https://docs.victoriametrics.com/anomaly-detection/components/models/#autotuned) model wrapper. This feature is automatically enabled if the data is timezone-aware and its timezone is not set to the default ('UTC'), otherwise default timezone-free optimization flow will be used.

+
+> **Note**: Starting with [v1.18.2](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1182), the format for `tz_seasonalities` has been updated to enhance flexibility. Previously, it accepted a list of strings (e.g., `['hod', 'minute']`). Now, it follows the same structure as custom seasonalities defined in the `seasonalities` argument (e.g., `{"name": "hod", "fourier_order": 5, "mode": "additive"}`). This change is backward-compatible, so older configurations will be automatically converted to the new format using default values.

 *Parameters specific for vmanomaly*:
 
 * `class` (string) - model class name `"model.prophet.ProphetModel"` (or `prophet` starting from [v1.13.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#1130) with class alias support)
 * `seasonalities` (list[dict], optional): Additional seasonal components to include in Prophet. See Prophet’s [`add_seasonality()`](https://facebook.github.io/prophet/docs/seasonality,_holiday_effects,_and_regressors.html#modeling-holidays-and-special-events:~:text=modeling%20the%20cycle-,Specifying,-Custom%20Seasonalities) documentation for details.
 - `tz_aware` (bool): (Available since [v1.18.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1180)) Enables handling of timezone-aware timestamps. Default is `False`. Should be used with `tz_seasonalities` and `tz_use_cyclical_encoding` parameters.
-- `tz_seasonalities` (list[str]): (Available since [v1.18.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1180)) Specifies timezone-aware seasonal components. Requires `tz_aware=True`. Supported options include `minute`, `hod` (hour of the day), `dow` (day of the week), and `month` (month of the year).
+- `tz_seasonalities` (list[dict]): (Available since [v1.18.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1180)) Specifies timezone-aware seasonal components.

Starting with [v1.18.2](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1182), users can configure additional parameters for each seasonality, such as `fourier_order`, `prior_scale`, and `mode`. For more details, please refer to the **Timezone-unaware** configuration example below.
 - `tz_use_cyclical_encoding` (bool): (Available since [v1.18.0](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1180)) If set to `True`, applies [cyclical encoding technique](https://www.kaggle.com/code/avanwyk/encoding-cyclical-features-for-deep-learning) to timezone-aware seasonalities. Should be used with `tz_aware=True` and `tz_seasonalities`.
