R: Error when trying to transmute a data.table

After upgrading R recently, I've starting getting an error when trying transmute a data.table, stating that := can only be used on a quasi quoted argument. I've searched for a fix but came up short. Reproducible example below using R 3.5.1. Any advice?

library(dplyr) #0.7.8
library(data.table)  #1.11.8
library(dtplyr) #0.0.2 

set1 = mtcars %>% data.table()  
transmute(set1 ,mpg2 = mpg*1)

Error: := can only be used within a quasiquoted argument

Solved by using the development version of dtplyr:

Convert set1 into a tibble.

set1 %>% as_tibble() %>% transmute(mpg2 = mpg * 1)
