+**12/04/2025:** The `get_continuous()` function was added to the `waterdata` module, which provides access to measurements collected via automated sensors at a high frequency (often 15 minute intervals) at a monitoring location. This is an early version of the continuous endpoint and should be used with caution as the API team improves its performance. In the future, we anticipate the addition of an endpoint(s) specifically for handling large data requests, so it may make sense for power users to hold off on heavy development using the new continuous endpoint.

 **11/24/2025:** `dataretrieval` is pleased to offer a new module, `waterdata`, which gives users access USGS's modernized [Water Data APIs](https://api.waterdata.usgs.gov/). The Water Data API endpoints include daily values, instantaneous values, field measurements (modernized groundwater levels service), time series metadata, and discrete water quality data from the Samples database. Though there will be a period of overlap, the functions within `waterdata` will eventually replace the `nwis` module, which currently provides access to the legacy [NWIS Water Services](https://waterservices.usgs.gov/). More example workflows and functions coming soon. Check `help(waterdata)` for more information.
 
 **09/03/2024:** The groundwater levels service has switched endpoints, and `dataretrieval` was updated accordingly in [`v1.0.10`](https://github.com/DOI-USGS/dataretrieval-python/releases/tag/v1.0.10). Older versions using the discontinued endpoint will return 503 errors for `nwis.get_gwlevels` or the `service='gwlevels'` argument.
