[Gambas-user] Gambas stable builds

[corradoventu at ...69...]

According page: 
https://launchpad.net/~gambas-team/+archive/ubuntu/gambas3
the current gambas version should be 3.7
but ubuntu 15.4 software center installs gambas3-ide 3.5.4-2ubuntu3
(here the lines from gambas system information)

[System]
Gambas=3.5.4
OperatingSystem=Linux
Kernel=3.19.0-14-generic
Architecture=x86_64
Distribution=Ubuntu 15.04
Desktop=GNOME
Theme=QGtk
Language=en_US.UTF-8
Memory=1929M

I know I can install from PPA (in fact I'm using 3.7.90 from daily PPA)
but I think this is a problem.
Should I open the problem to Ubuntu? Or to Gambas? On none?
Thanks for your attention
Corrado
