When will you tag the next release version of Tvheadned? Latest tag is v4.0.9 in March 2016
And when will you release this next new 'stable' version of Tvheadend package for Ubuntu?
PS: Please remember that Linux distos do not create packages unless they have version tags.
Mint, Debian, Fedora, openSUSE, etc. does not include newer package unless you tag version.
Please try to tag and release often so that downstream Linux distros will update packages.
