@amilan17 sorry I forgot the discussion in the meeting... This proposal was approved in the past but dropped from the publication of PDF manual, so it will be included in the next publication (no need to change github csv), is that right? In this case, can I move this to "validated" status?

[amilan17]

correct. no need to need to create and edit a branch for this.

@amilan17 thanks, then I move this to validated status.
