# forcats 0.5.1
* Re-license as MIT (#277).
* `fct_lump_n()` no longer uses a partial argument name (@malcolmbarrett, #276).
# forcats 0.5.0
* `as_factor()` gains a logical method that always returns a factor with
levels "FALSE" and "TRUE" (#185).
* `fct_c()`, `fct_collapse()` and `fct_recode()` are now explicitly
documented as using [dynamic dots](https://rlang.r-lib.org/reference/dyn-dots.html)
(@labouz, #234).
* `fct_collapse()` now accepts a `other_level` argument, to allow a
user-specified `Other` level (@gtm19, #194). It now correctly collapses
factors when `other_level` is not `NULL` (#172), and makes `"Other"` the
last level (#202) (@gtm19, #172 & #202)
* `fct_count()` no longer converts implicit NAs into explicit NAs (#151).
* `fct_inseq()` behaves more robustly when factor levels aren't all numbers
(#221).
* `fct_lump()` has been split up into three new functions: `fct_lump_prop()`,
`fct_lump_n()`, and `fct_lump_lowfreq()`. (@jonocarroll, #167, #142).
All `fct_lump_()` functions check their inputs more carefully
(@robinson_es, #169)
* `fct_reorder2()` gains a helper function `first2()`, that sorts `.y` by the
first value of `.x` (@jtr13).
The canonical form [1] of an R package Makefile includes the
following:
- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
needed), and CATEGORIES.
- HOMEPAGE is not present but defined in math/R/Makefile.extension to
refer to the CRAN web page describing the package. Other relevant
web pages are often linked from there via the URL field.
This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Helpers for reordering factor levels (including moving specified
levels to front, ordering by first appearance, reversing, and randomly
shuffling), and tools for modifying factor levels (including
collapsing rare levels into other, 'anonymising', and manually
'recoding').
