This release is mostly bug fixes, but there are a couple of new features you might care out.

• There are three new datasets, fruit, words and sentences, to help you practice your regular expression skills:

str_subset(fruit, "(..)\\1")
#> [1] "banana"      "coconut"     "cucumber"    "jujube"      "papaya"
#> [6] "salal berry"
#> [1] "The birch canoe slid on the smooth planks."
• More functions work with boundary(): str_detect() and str_subset() can detect boundaries, and str_extract() and str_extract_all() pull out the components between boundaries. This is particularly useful if you want to extract logical constructs like words or sentences.
x <- "This is harder than you might expect, e.g. punctuation!"
#> [1] "This is harder than you might expect, e.g. punctuation!"
• str_view() and str_view_all() create HTML widgets that display regular expression matches. This is particularly useful for teaching.
