#### **Atlas**

📊 **Export analytics charts as PNG** You can now save any chart on the Analytics page as a PNG image by clicking the camera icon — making it easier to share results and include visuals in reports.

📅 **Representative period now visible** The representative period for your data is now shown on both the **Analytics** and **Download** tabs.

#### **Whiffle Wind**

**Fixed tooltip visibility for wind farm placement** A bug that caused the wind farm placement tooltip (explaining whether a farm is inside or outside the LES boundary) to be partially hidden behind the map has been fixed. The full guidance is now visible.

#### **Measurements in Whiffle Wind**

*This feature is behind a feature flag. Early access is available via Whiffle Support.*

**Smarter measurements uploader** Uploading measurement data is now more flexible and forgiving:

* **Sensor names with brackets** are now accepted, removing a common source of upload errors.
* **Special characters in column headers** are supported, and leading/trailing spaces are automatically trimmed so your data is cleaned on import.
* **Automatic timezone conversion** handles timestamps with UTC offsets, so you don't need to pre-process time data manually.
* **Timestamps are trimmed automatically**, preventing hidden whitespace from causing failures.
* **Clearer time format errors** — if a time format isn't recognised, you'll now get a specific error message.
* **CSV delimiter auto-detection** means both comma- and semicolon-separated files are accepted without any manual adjustment.
* **Most characters in file names** are now supported, so you rarely need to rename files before uploading.
* **More flexible timestamp column names** — in addition to "Timestamp" and "Time", the uploader now recognises variations like lowercase "time" and "timestamp".
* **Common placeholder values** such as `-99`, `9999`, `9999.99`, `-`, and empty strings are now automatically treated as missing data (NaN), preventing these from skewing your results.

**Validation for measurement heights** Atlas now checks that every measurement height includes both a wind speed and wind direction, catching incomplete configurations before they cause issues downstream.

**Status icons in Measurements and Geodata lists** Measurements and Geodata items now display a clear status icon showing whether an item is a **draft** or has been **marked as final** — so you can quickly see what's ready to use in a simulation.

## 2026-01-29

* Implemented **automatic name saving** in the Simulation Wizard. Simulation names are now saved while typing, preventing loss of draft data.
* Added **plots in the Atlas side panel** for **Weibull, wind rose, and vertical wind speed profiles**, making it easier to **inspect weather data on the fly**. *This feature is behind a feature flag and will be available shortly.*
* Added **Measurements, Geodata, and Support info** to the Simulation Detail page, allowing both users and Whiffle Support to see which data was used in a **Via Support** run.
* **Default number of wind sectors** is now **12 instead of 16** for Statistics data in Whiffle Wind.
