It can be seen that the list of packages has been updated on 15-Apr-2016 https://downloads.openwrt.org/snapshots … packages/.
There are only three python v2.7 packages available
python-base
python-codecs
python-light
When installed python-light there is problem with error as "ImportError: No module named logging" when python is used.
On Chaos Calmer those and more packages are available for python v2.7 such as python-logging_2.7.9-6_ar71xx.ipk, python-gdbm_2.7.9-6_ar71xx.ipk,..
Why those packages are not available at snapshot download area?
