stringr 1.3.0

API changes

• During package build, you may see
  Error : object ‘ignore.case’ is not exported by 'namespace:stringr'.
  This is because the long deprecated str_join(), ignore.case() and
  perl() have now been removed.

New features

• str_glue() and str_glue_data() provide convenient wrappers around
  glue and glue_data() from the glue package
  (#157).

• str_flatten() is a wrapper around stri_flatten() and clearly
  conveys flattening a character vector into a single string (#186).

• str_remove() and str_remove_all() functions. These wrap
  str_replace() and str_replace_all() to remove patterns from strings.
  (@Shians, #178)

• str_squish() removes spaces from both the left and right side of strings,
  and also converts multiple space (or space-like characters) to a single
  space within strings (@stephlocke, #197).

• str_sub() gains omit_na argument for ignoring NA. Accordingly,
  str_replace() now ignores NAs and keeps the original strings.

Bug fixes and minor improvements

• str_trunc() now preserves NAs (@ClaytonJY, #162)

• str_trunc() now throws an error when width is shorter than ellipsis
  (@ClaytonJY, #163).

• Long deprecated str_join(), ignore.case() and perl() have now been
  removed.
