I was always talking about the 5.1 beta, as I explained in earlier post.
"Thanks for the update Khorvat, I thought 5.1 will be released soon as you mentioned above "It's a matter of days as I mentioned v5.1 release date was planned to be same as v4.9 but because of some tech issues we had to postpone for few days""
If you mean one click upgrade, no there won't be an easy way to do that, but you will have braking changes list and you will need to follow the list in order to upgrade. It comes down to the amount of code you have written, if you were intensively using e.g. repositories you will have to rewrite all the constructor lines in order to resolve the repository with the DI etc.
"Also - will you also provide an easy way to upgrade from 4.9 to 5.1 as there will be major changes in 5.1 ?"
