What's new in Solidworks Composer Beta 2???

All of the things i have tried with Composer 2018 Beta 2 whats new are all available and reproducible in Composer 2017 SP3.

Even files from Composer 2018 open in 2017 and Saved smg from Solidworks 2018 opens in 2017sp3.

I have been testing composer 2018 and found some really annoying bugs, but whatever i report is already reproducible in 2017sp3.

The Whats new says its 2018 stuff, but all of it possible in 2017sp3.

Why include Composer in Beta? if its just repackaged 2017sp3.
