I had a look at
https://github.com/analogdevicesinc/libiio/releases/tag/v0.15, and it
looks like between 0.14 and 0.15, the number of commits is fairly
limited, and the vast majority of them are fixes. So I believe it
should be OK to directly take this bump to 0.15 in the LTS release.

Peter, do you agree ?

Best regards,

Thomas
