c++ - VCRedist compatibility across VS Updates, library linking and dll usage -

-

i know, vredists not compatible between major versions of visual studios (2013 not compatible 2015 , vcredist of 215 needed install because of different stl implementations - right?). however, not sure, minor versions - updates.

let's say, have 2 developement environments:

a) vs 2015 update 2 - 14.0.25123.00 vcredist 14.0.23918
b) vs 2015 update 3 - 14.0.25421.03 vcredist 14.0.24210

1)
i have lib / dll (particullary opencv 2.4.13) built vs 2015 update 2 (environment a) ), can library linked program in vs 2015 update 3 (environment b) )? can user safely run program vcredist 14.0.23918 installed or needed install vcredist 14.0.24210?

and reversed situation...

2)
the lib / dll built vs 2015 update 3 (environment b) ), can library linked program in vs 2015 update 2 (environment a) )? can user safely run program vcredist 14.0.23918 installed?

answers appreciated.
