It is easy to understand. IPS need money and they must blow upp someone ... for now are owners of lifetime licenses - how??
Before was invision power board (product) - today is new product - "core" package and when you buy new product - you will get only invision board ... what i can said ...same "faeces" but in new package.
I moved back on vb 4 ... was disappointed with IPB - editor problems and losing many of my posts ... two years problems with editor and code tags and still problems ... in vb4 works everything fine ..for my needs ... (this is my opinion)!
Every update of IPB = editor was problem (3.1.4 to 3.2.0, 3.2.0 to 3.2.x, 3.2.x to 3.3.x and last 3.3.x to 3.4.x - nearly 2 years). For me that says that development team can not execute their work - change team and let them to experiment next few years ... or send them to extra education, but try to sell finished and working product.
Editor is most immportant part of every community /where people still write posts and make threads).
