v1.2

Bug fixes

• The tibble.width option is used for glimpse() only if it is finite (#153, @kwstat).
• New as_tibble.poly() to support conversion of a poly object to a tibble (#110).
• add_row() now correctly handles existing columns of type list that are not updated (#148).
• all.equal() doesn't throw an error anymore if one of the columns is named na.last, decreasing or method (#107, @BillDunlap).

Interface changes

• New add_column(), analogously to add_row() (#99).
• print.tbl_df() gains n_extra method and will have the same interface as trunc_mat() from now on.
• add_row() and add_column() gain .before and .after arguments which indicate the row (by number) or column (by number or name) before or after which the new data are inserted. Updated or added columns cannot be named .before or .after (#99).
• Rename frame_data() to tribble(), stands for "transposed tibble". The former is still available as alias (#132, #143).

Features

• add_row() now can add multiple rows, with recycling (#142, @jennybc).
• Use multiply character × instead of x when printing dimensions (#126). Output tests had to be disabled for this on Windows.
• Back-tick non-semantic column names on output (#131).
• Use dttm instead of time for POSIXt values (#133), which is now used for columns of the difftime class.
• Better output for 0-row results when total number of rows is unknown (e.g., for SQL data sources).

Documentation

• New object summary vignette that shows which methods to define for custom vector classes to be used as tibble columns (#151).
• Added more examples for print.tbl_df(), now using data from nycflights13 instead of Lahman (#121), with guidance to install nycflights13 package if necessary (#152).
• Minor changes in vignette (#115, @Helix123).
