Can someone help me on how to resolve package conflicts with dev'ed packages?

Hi Dilum and Tim @tim.holy

Need either my existing Julia packages running in base Julia v1.04 or v1.05 LTS to run in
base Julia v1.4.2 or vice versa. So I suggested
"… suggest to package authors that they install CompatHelper.jl.”
and the response was
“I used to try to maintain compat with older Julia versions, but noticed that it took
a lot of my bandwidth for little gain and decided to not pursue that anymore.”
as described here >> [ANN] DynamicAxisWarping.jl - #6 by baggepinnen

I like all the cool mathematical and scientific algos Fredrik Bagge Carlson writes,
but I have just as many working in base Julia v1.05 LTS that I really don’t want to break ;
So might you want to reach out to Fredrik and find out what was slowing him down so much
that he gave up on maintaining backward compatibility and address that issue ?

Best !,
