cheapr 0.9.9

• New functions cheapr_var and cheapr_rev.

• get_breaks has been improved and a few small bugs have been fixed.

• as_discrete gains a new argument inf_label.

• Safety improvements to as_discrete.

• Removed internal C++ functions as package installation was failing for
  some machines.

cheapr 0.9.3

• Range based subsetting, e.g. sset(x, 1:10) should now be faster.

• New functions val_count and which_val for common scalar operations.

• Some functions gain a 'names' argument.

• Replaced calls to STRING_PTR with STRING_PTR_RO to satisfy R package check results.

• lag_ should now be somewhat faster.

• Fixed a small bug in lag2_ that would produce incorrect results when supplying a vector of lags and an order vector.

cheapr 0.9.2

• A signed integer overflow bug in lag2_ has been fixed. This occurred when
  supplying NA lags.

• lag2_ no longer fills the names of named vectors when the fill value is supplied.

cheapr 0.9.1

• New function recycle to help recycle R objects to a common size.

• The set functions that update by reference are now ALTREP aware and
  take a copy when the input is an ALTREP object.

• New function lag2_ as a generalised solution for complex lags. It supports
  dynamic lag vectors, lags using an order vector, and custom run lengths.
  It doesn't support updating by reference or long vectors.

cheapr 0.9.0

• New function lag_ for very fast lags and leads on vectors and data frames.
  It includes a set argument allowing users to create a lagged vector
  by reference without copies.

• set_round has been amended to improve floating point accuracy.

cheapr 0.8.0

• New 'set' Math operations inspired by 'data.table' and 'collapse'
  that transform data by reference.

• Fixed an inconsistency of when sequence_() would error when supplied with
  a zero-length size argument.

• Fixed a protection stack imbalance in count_val(x) when x is NULL.

• sset has been optimised for wide data frames with many variables.
  It is also faster when applied to a data frame with dates, date-times and factors.

• In sset, when i is a logical vector it must match the length of x.

• sset can now handle 'ALTREP' compact real sequences as well.
