Are the new directives the same?

Hi. I'm using Vivado 2016.2 for implementation with some congestion-related strategies (mainly SpreadLogic_high). The thing is that I just found out that I was using the manual from Vivado 2015.3, and after looking at the latest one, I could see that some directives changed names.

Are these directives mapped to the same algorithms? Or are they different? An example would be the following.

 

In Vivado 2015.3, I would write this place_design directive

SpreadLogic_high

 

And in Vivado 2016.2 I would write this one

AltSpreadLogic_high

 

Thanks!
