  • New vec_run_sizes() for computing the size of each run within a vector. It
    is identical to the times column from vec_unrep(), but is faster if you
    don't need the run key (#1210).

  • New sizes argument to vec_chop() which allows you to partition a vector
    using an integer vector describing the size of each expected slice. It is
    particularly useful in combination with vec_run_sizes() and list_sizes()
    (#1210, #1598).

  • New obj_is_vector(), obj_check_vector(), and vec_check_size() validation
    helpers. We believe these are a better approach to vector validation than
    vec_assert() and vec_is(), which have been marked as questioning because
    the semantics of their ptype arguments are hard to define and can often be
    replaced by vec_cast() or a type predicate function like
    rlang::is_logical() (#1784).

  • vec_is_list() and vec_check_list() have been renamed to obj_is_list()
    and obj_check_list(), in line with the new obj_is_vector() helper. The
    old functions have been silently deprecated, but an official deprecation
    process will start in the next vctrs release (#1803).

  • vec_locate_matches() gains a new relationship argument that holistically
    handles multiple matches between needles and haystack. In particular,
    relationship = "many-to-one" replaces multiple = "error" and
    multiple = "warning", which have been removed from the documentation and
    silently soft-deprecated. Official deprecation for those options will start in
    a future release (#1791).

  • vec_locate_matches() has changed its default needles_arg and
    haystack_arg values from "" to "needles" and "haystack", respectively.
    This generally generates more informative error messages (#1792).

  • vec_chop() has gained empty ... between x and the optional indices
    argument. For backwards compatibility, supplying vec_chop(x, indices)
    without naming indices still silently works, but will be deprecated in a
    future release (#1813).

  • vec_slice() has gained an error_call argument (#1785).

  • The numeric_version type from base R is now better supported in equality,
    comparison, and order based operations (tidyverse/dplyr#6680).

  • R >=3.5.0 is now explicitly required. This is in line with the tidyverse
    policy of supporting the 5 most recent versions of
    R    .
