# 20240424A v 1.4.5

### Analyst release notes

| Release date | Software version |
| --- | --- |
| 24.4.2024 | 1.4.5 |

### General improvements

- **New Meteo quality control**
  - New automatic QC methods were added for TEMP parameters.
  - Physical minimum and maximum limits for AP were improved to account for the site elevation.
  - Parts of the Meteo screen were redesigned, each parameter type has a separate list of automatic tests and their parameters.
  - Added Meteo QC status after Meteo quality control is finished.
- **GHI-GTI 2-component test and GTI fix consistency test**
  - A new 2-component test for comparing GHI and GTI parameters is now available in a radiation automatic quality control.
  - A new consistency test for comparing GTI fix with GHI, DNI, and DIF parameters is now available in a radiation automatic quality control.
- **Dataset validation and dataset automatic updates**
  - Improved speed of dataset validation and automatic update of datasets when opening a project or adding a dataset into a project.
  - All automatic updates are logged into a change log and stored with the dataset.
  - Added busy indicator while dataset validation is running.
- **New flag color schema**
  - To improve the readability of the QC results heatmap and distinguish different flags, a flag color schema was updated.
- **Metadata editor**
  - Removed “Instrument description” and “Test groups” columns in a Metadata editor to simplify the screen and improve readability. To modify test groups, use the “Edit test groups“ button in a Metadata editor.
  - GTI configuration is prefilled by default values and has more tooltips explaining each field.
- **Importer**
  - Improved parameter type detection now supports GTI parameter type
  - Improved prefilling of metadata from the import file. More fields and abbreviations are recognized and automatically prefilled during import.
  - Primary buttons are highlighted to help users navigate through the import process.
- **Calculator**
  - Predefined functions available in the calculator can also be used in an expression selector.
  - Sun azimuth function is renamed to sun aspect, so calculated values match the name.
- **Metadata, importer, calculator**
  - Parameter name, dataset name, and database name are limited to alpha-numeric characters, '_', and spaces.
  - Custom units are not supported anymore, a user has to pick one of the supported units by the system.
- **Time reference check**
  - Possibility to reorder new shifts in a descending order.
- **PDF report**
  - Possibility to turn off data availability in the quality control summary table. This is used for shorter datasets, to avoid insufficient quality state (red color).
  - Small improvement for better readability.
- **New Combine datasets dialog**
  - A new Combine dialog with better usability is now available. New dialog includes functionality from Join and Combine dialogs, all options in one place.
- **Clone dataset**
  - Clone dataset now supports clipping maintenance logs together with a dataset
- **CSV export with full Solargis header**
  - Added missing metadata into exported CSV file.
- **Analyze, Time series, Compare improvement**
  - Users can easily deselect all flags
- **Removed popup informing about missing GTI config**
  - Popup informing about missing GTI config is not shown anymore when a user opens a dialog window. Instead, a dataset with missing GTI config is highlighted in orange color on the main screen.
- **New metadata format**
  - We updated how metadata is stored in a dataset and a DB. An older dataset is automatically updated to a new format while it is opening for the first time. Opening an updated dataset to a newer Solargis Analyst version in an older Solargis Analyst version might result in errors or unexpected behavior.
  - The first application start, after installing Solargis Analyst version 1.4.5, might take longer because all datasets in the current project are validated and updated to a newer format. Next time a project is opened, datasets are only validated and no updates are needed.

### Deprecated features and platforms

- **MAC and Linux OS**
  - We temporarily stopped supporting MAC and Linux operating systems, however, it is still possible to use Solargis Analyst in a Windows virtual machine on these operating systems.
- **Windows 8 OS**
  - As a reminder, Windows 8 has reached the end of support. Solargis Analyst running on Windows 8 will be still working, but Solargis will no longer provide technical support for any issue.

### Minimum system requirements

- Minimum RAM capacity changed to 16 GB
- Updated minimum system requirements for RAM capacity from 8 GB to 16 GB. Solargis Analyst works with big datasets and performs a large amount of calculations, therefore it is recommended to have at least 16 GB RAM available or more while using Solargis Analyst.

### Known issues

- **Timeout error**
  - When Solargis Analyst is open for a long time, it is possible to get a timeout error while opening a screen or loading data. To fix it, refresh datasets on the main screen. This will be improved in future releases.
