@ -33,6 +33,8 @@ Highlights:
|
||||
warning is logged. The warning is additional to the one already printed in the core device log upon
|
||||
detection of the error.
|
||||
* Removed worker DB warning for writing a dataset that is also in the archive
|
||||
* Extended Kasli gateware JSON description with configuration for SPI over DIO.
