Enhancements: 

• Reloading Previous Workspace – When launching Central, users will have the option to reopen the application windows from their previous session
• Central will now alert users that their headstage is in impedance mode when recording on Cerebus data acquisition systems (RS-0048 Specific)
• Channels’ configuration menu can now be accessed directly in Raster Plot by right-clicking
• Users can now configure Line Noise Cancellation settings via the cbMEX API
• Added color changing capability for color blindness using Window’s File Registry application on Central

Bug Fixes: 

• Changing the external gain value in a channel’s settings menu will no longer cause packet loss issues

• The File Storage application’s “Section” field segments properly for systems supporting PTP timestampsUpdated Central to scale text size based on Windows Display settings
• Resolved a rarebug where the CerePlex Direct displayed 0 front end channels in the Cereplex Direct software
• Resolved an issue where files recorded with cbMEX were encountering incorrect values in their Data.Comments.TimestampStartedand NEV.Data.Comments.TimestampStartedSec fields

Changes:

• Removed the “1 Chan per file” option from the File Storage application
• Prefixes for channel sources were added to the channel name in the Hardware Configuration application and to saved files (e.g. Hub1-, Hub2-, NSP-)

Known Issues:

• For Central Configuration Files (.ccf) that have an analog output configured for persistent waveform generation without a specific trigger (e.g. instant), the output does not automatically execute when loading in the .ccf. A workaround is to manually enable the analog output within Central or cbMEX API after loading the .ccf.

Known Issues: 

• Soft Sync Line Noise Cancellation (LNC) does not remove the harmonics for 50/60
  Hz line noise (e.g. 100/120 Hz, 150/180 Hz)
