# RELEASE 12.22.0
**February 12, 2026**
# **PlantPredict**
### **PVGIS Weather Data Integration**
PlantPredict now offers direct, in-app access to **PVGIS weather data** — enabling seamless download and file upload of PVGIS weather datasets without ever leaving the application. Best of all, this is a **free service** and does not require a separate PVGIS API key, making it easier than ever to source high-quality irradiance and meteorological data for your projects.
### **New PlantPredict Product Documentation Portal**
We are excited to announce the launch of the [**PlantPredict Product Documentation Portal**](https://docs.plantpredict.com/) — a centralized, modern documentation hub for all PlantPredict products. The portal brings together comprehensive resources across the entire PlantPredict ecosystem in one easy-to-navigate site, including:
* **PlantPredict User Guide** — Step-by-step instructions for using PlantPredict's interface, creating projects, and running predictions.
* **Models & Algorithms** — In-depth technical documentation of the underlying physics models, algorithms, and calculation methodologies that power PlantPredict's energy simulations.
* **API & SDK** — Developer resources for programmatic access, including REST API documentation, Postman collections, Swagger references, and the Python SDK.
* **Pro Tools Documentation** — Dedicated user guides for **Design Pro**, **Terrain Pro**, and **Voltage Pro**.
* **Extensions** — Information on third-party integrations such as the PVRADAR Soiling Extension.
* **Release Notes** — A complete history of all product updates, improvements, and fixes.
The portal also features built-in search, AI-powered assistance, and a clean, modern interface designed to help you find the information you need — fast.
## **Features & Improvements**
* **New 3D Scene Outputs in Nodal API Responses** — API users can now retrieve 3D scene output data as part of the Nodal JSON response, unlocking richer programmatic access to simulation geometry and results.
* **Measured Labels Toggle for Constraints & Site Boundaries** — A new toggle option allows users to display measured labels on constraints and site boundaries.
* **Smarter AC Block Array Shapes in Map Builder** — Improved automation logic for AC Block Array geometry within Map Builder now prevents excessively wide or tall block shapes, resulting in more balanced and practical layouts.
* **Expanded Postman API Documentation** — The Postman collection has been significantly updated with many previously missing endpoints and comprehensive descriptions for essentially all requests, making API integration smoother and more intuitive.
* **Larger File Support for 3D Scene Tracker Rotation Angles** — The file upload process for 3D Scene tracker rotation angles now accommodates much larger file sizes, removing previous limitations for large projects.
* **GCR Unit Label on DC Field Form** — Added the missing unit label (%) for Ground Coverage Ratio (GCR) on the DC Field form for improved clarity.
## **Bug Fixes**
* Fixed NSRDB weather downloads that were missing albedo data.

# **Pro Tools**
# **Terrain Pro**
## **Features & Improvements**
### **Extended DXF Import Compatibility**
Terrain Pro now supports DXF files generated from **Global Mapper** in addition to Autodesk software, expanding interoperability and improving workflow flexibility for users working across multiple GIS and CAD platforms.
### **Improved Pile Icon Visualization**
Optimized pile icon rendering to properly scale across different zoom levels. This enhancement prevents graphical overlapping when zooming out and improves overall map readability at any scale.
## **Bug Fixes**
* **Earthwork Heatmap Rendering** — Fixed an issue where the Earthwork heatmap appeared scattered and displayed missing sections in small layout areas. The heatmap now renders correctly and consistently regardless of layout size.
