good morning saguaros!
yes, I recently installed with the new version 2.7.1... I was also able to install it without any problem... only thing is that when we update other extensions like blank template BS5 and the T4 plugin system, and if you click on "changelog" it doesn't show any changelog which is very usefull before going though the update... in my case I installed the JA extension manager mainly because that feature...
thanks!
