This opinion is backed up by 18 years of experience in the IT and computer industry, following, testing and using various versions of Linux based servers and SME since version 3.1.
I do read daily this Forum, Devinfo list, and some developers forums and well aware of all the publicly available issues and solutions. I do try to help the community whenever I can and don't bother busy developers with many questions.
Yes, I have installed and testing SME 6 beta and so far the only problems I have seen are not directly related to SME itself, but contributed add-ons, which need to be updated to fit properly to the new menu layout. Since it is not Mitel's bug I have not submitted it to Mitel. If I discover something that worth developers attention, I will submit as a bug-report to Mitel.
I am not trying to be critic or offensive, but just was stating the fact that project of this complexity as SME after major version upgrade MAY have some bugs dispute intensive testing and MAY have some issues with third party software often used to complement built-in features until they updated are to be compatible.
You don't have to be that defensive. I respect and admire your work and grateful that I can use this wonderful peace of work.
