Issue with as_date reading a character with date and time

[kerry-ja]

With version 1.7.0 the as_date function does not convert a character with a date and time to a date, instead it returns NA with a warning. The expected value to be returned was a date with the time portion dropped. In version 1.6.0, the function converted the character to a date.

Hm, sorry about that. That was a consequence of #536 and #527 and it didn't strike me as breaking change. You usage is rather unusual, but for the sake of the backward compatibility I will fix it asap.

I appreciate the very quick fix, however I still have the same issue. I thought that perhaps even though I did install the update, which was available perhaps I needed to install from github, however when I tried I got an error.
devtools::install_github("tidyverse/lubridate")
