tibble 3.0.2

Bug fixes

• [[ works with classed indexes again, e.g. created with glue::glue() (#778).
• add_column() works without warning for 0-column data frames (#786).
• tribble() now better handles named inputs (#775) and objects of non-vtrs classes like lubridate::Period (#784) and formattable::formattable (#785).

Performance

• Subsetting and subassignment are faster (#780, #790, #794).
• is.null() is preferred over is_null() for speed.
• Implement continuous benchmarking (#793).

Compatibility

• is_vector_s3() is no longer reexported from pillar (#789).
