## foton changes
|
|
|
- FilterFile object creation in python-foton now can take two additional arguments:
|
|
|
- 'create_if_not_exist', set to 'False' to avoid creating a new foton file if one doesn't exist. This makes it easier to find errors related to the wrong file path.
|
|
|
- set 'read_only' to 'True' to avoid writing foton files altogether.
|
|
|
- set environment variable FOTON_WARN_RHP_ZEROS=false to ignore warnings about zeros in the right-hand plane.
|
|
|
- some warnings in foton are made a bit nicer and less cluttered.
|
|
|
- Foton and python-foton can now always produce a design string that exactly matches a filter. Previously, foton would delete or change filters that didn't have exact design strings.

## diaggui changes
|
|
|
- Difference cursors are now useful. The second cursor now stays at the value entered. Spin controls work, and negative differences work.
|
|
|
- Some improvements to error messages when swept-sine and sine-response argument types are wrong.
|
|
|
- Reports an error if you try to send a filter with more than 20 second-order-sections as part of an excitation.
|
|
|
- When switching to User NDS inputs, excitation channels are also switched.
|
