Added the ability to customize the report to display or hide specific metrics or metric sections. A column of checkboxes on the right side of the report allows users to select individual metrics or metric sections. These selections can be saved in the meter’s settings or exported to a settings file for use with other meters. The report may be customized in a file view or in a template within the meter’s settings view.

• Information entered into the 'General Info' fields in the report view is now properly stored in the file and will persist when the file is opened again. • Markers entered while the meter is running are now properly inserted into the Time History graph. • PDF reports in character-based languages (Thai, Korean, etc.) now display correctly.

• Added support for Spartan 821/721 and SoundExpert 821/721 meters. • When adding a meter to Atlas by IP address or host, Atlas now checks if the address/host has already been used, to prevent issues caused by having two meter entries with the same IP address. Other minor validation checks were also added. • Many improvements to graphs, spreadsheet and reports.
