Deprecated Feature Used

[catter1]

When trying to install wakatimer via devtools (devtools::install_github("uribo/wakatimer")), I get an error suggesting that the wakatimer package is using a depricated feature.

Warning: `data_frame()` was deprecated in tibble 1.1.0.
ℹ Please use `tibble()` instead.
ℹ The deprecated feature was likely used in the wakatimer package.
  Please report the issue at <https://github.com/uribo/wakatimer/issues>.
