I have been using the standard updater to get your development builds on Ubuntu. Recently I updated to version 17.04 and I no longer get updates. I used
sudo add-apt-repository ppa:dismine/valentina-dev
to add the repository, but the pointer still points to the ubuntu 2016 version (yakkety) instead of the 2017 version (zesty). Do you plan to start adding a copy of your latest build to the zesty ubuntu repository?
FWIW, many of the quirky behavior I saw in valentina in ubuntu yakkety version is now fixed when I run the same valentina under ubuntu after the zesty version. I am sure that is because I picked up a later version of Qt with their update.
