### General improvements

- **Automatic quality control**
  - Consistency test extended with GTI tracker.
  - A new method to detect linear interpolation of measured data.
  - Improvement of consecutive static value test in Meteo QC.
  - Added “mbar“ system unit for the AP parameter type.
  - Cloudless identification improved for methods in radiation QC.
- **PDF report**
  - Added new instrument class “No ISO Class.”
  - Added Glossary.
  - Legal information updated.
  - Removed the 'Time reference' row from the Quality control summary table, due to inconsistent behavior.
- **Time series**
  - Added 15 min and 30 min aggregation.
  - Compare more: New option to align time stamps of measured and model datasets.
- **Metadata, importer, calculator**
  - Not supported characters in column names and dataset names are replaced with '_'.
    - For more information, please visit [Name restrictions and limitations for special characters.](https://solargis.atlassian.net/wiki/spaces/public/pages/805208065) Location coordinates are rounded to 6 decimal places.
- **Calculator**
  - New functions added
    - sun_azimuth()
    - relative_difference()
    - calculate_GHI(), calculate_DNI() and calculate_DIF()
    - mod() to calculate modulo
    - For more information, please visit [Calculator](https://solargis.atlassian.net/wiki/spaces/public/pages/693403654).
- **Importer**
  - Applied time shifts during import are logged in the Time Shift log and the Change logs in a dataset.
- **Metadata editor**
  - Fix column names button helps rename all column names and replace not supported special characters with '_'.
- **Small improvements**
  - New instruments were added to the list of instruments.
  - Model and TMY datasets do not have test groups and they cannot be opened in radiation QC.
  - Usability improvements in the Maintenance log dialog.
  - Clone dataset added into the main menu under tools.
  - Consistency plot updated in Radiation QC for better readability.
- **Enhanced dataset metadata**
  - Added backtracking for vertical 1-axis tracker in GTI configuration (same for 1-axis horizontal and vertical trackers).
- 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.

### 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.
