Re: Mac HighDPI performance

 

It is not possible for me to make any kind of accurate time predictions
about when v6 might be released.  KiCad development does not move at a
constant pace.  Right now, we are at an all time high with developer
involvement but that may not last.  We have had a number of developers
come and go over the years so the project development tends to happen in
short bursts.  I wish I could give you a better answer than that but I
cannot.  I suspect this is the case with most if not all open source
projects.
