v1.3.1

• Subsetting zero columns no longer returns wrong number of rows (#241, @echasnovski).

• New set_tidy_names() and tidy_names(), a simpler version of repair_names() which works unchanged for now (#217).

• New rowid_to_column() that adds a rowid column as first column and removes row names (#243, @barnettjacob).

• The all.equal.tbl_df() method has been removed, calling all.equal() now forwards to base::all.equal.data.frame(). To compare tibbles ignoring row and column order, please use dplyr::all_equal() (#247).

• Printing now uses x again instead of the Unicode multiplication sign, to avoid encoding issues (#216).

• String values are now quoted when printing if they contain non-printable characters or quotes (#253).

• The print(), format(), and tbl_sum() methods are now implemented for class "tbl" and not for "tbl_df". This allows subclasses to use tibble's formatting facilities. The formatting of the header can be tweaked by implementing tbl_sum() for the subclass, which is expected to return a named character vector. The print.tbl_df() method is still implemented for compatibility with downstream packages, but only calls NextMethod().

• Own printing routine, not relying on print.data.frame() anymore. Now providing format.tbl_df() and full support for Unicode characters in names and data, also for glimpse() (#235).

• Improve formatting of error messages (#223).

• Using rlang instead of lazyeval (#225, @lionel-), and rlang functions (#244).

• tribble() now handles values that have a class (#237, @NikNakk).

• Minor efficiency gains by replacing any(is.na()) with anyNA() (#229, @csgillespie).

• The microbenchmark package is now used conditionally (#245).
