hi,
i just pushed the qdsp-start package and all relevant GPS packages into the Linaro archive for Debian stretch, so GPS should now work in latest builds as well. Thanks for reporting it.
It is the exact same s/w as the last release, there was no change, so there will not be any improvement in the stack, but at least it will behave the same way on the latest builds.
[ and for reference, the latest builds are based on Debian stretch version , while the previous ones were built for Debian Jessie, so we needed to rebuild the packages ]
