Gst registration required or not if less than 20l turnover

I am into manpower service business and have recently started the firm. 

I have heard that earlier, even if turnover is less than Rs. 20 L, but if you are making inter-state business, you need to register for GST, but there is a recent news (I could not verify the same) that the same has been stated now that we need not register if transaction is less than Rs. 20 L, even in case of inter-state transfer.

Please help me to know whether I will have to register for GST after going through the following details

- My firm is in Gujarat

- Turnover will be less than Rs. 20 Lacs per annum, at least for this year

- I will be having clients across India, so will be supplying manpower across India
