The 'Conditional Formatting' option is still available in version: 2.43.4647.541 (Feb 2017). But this option only applies to aggregated values or measures. Otherwise, it is disable if you don't summarize the value field.

I found a workaround for this. First, choose an aggregated function for example Sum (even though you might not need to do this function). Then apply the conditional formatting for this field. After that remove the function by checking "don't summarize option" when clicking right by the name of the field on the visualization navigation bar. Amazingly, it keeps the conditional formatting.
