• The default version of Bioconductor has been changed to 3.14.
  (This is used by setRepositories and the menus in GUIs.)

UTILITIES:

• R CMD check --as-cran has a workaround for a bug in versions of
  file up to at least 5.41 which mis-identify DBF files last
  changed in 2022 as executables.

C-LEVEL FACILITIES:

• The legacy S-compatibility macros SINGLE_* in R_ext/Constants.h
  (included by R.h) are deprecated and will be removed in R 4.2.0.

BUG FIXES:

• Initialization of self-starting nls() models with initialization
  functions following the pre-R-4.1.0 API (without the ...
  argument) works again for now, with a deprecation warning.

• Fixed quoting of ~autodetect~ in Java setting defaults to avoid
  inadvertent user lookup due to leading ~, reported in PR#18231 by
  Harold Gutch.

• substr(., start, stop) <- v now treats negative stop values
  correctly. Reported with a patch in PR#18228 by Brodie Gaslam.

• Subscripting an array x without dimnames by a
  length(dim(x))-column character matrix gave "random" non-sense,
  now an error; reported in PR#18244 by Mikael Jagan.

• ...names() now matches names(list(...)) closely, fixing PR#18247.

• all.equal(*, scale = s) now works as intended when length(s) > 1,
  partly thanks to Michael Chirico's PR#18272.

• print(x) for long vectors x now also works for named atomic
  vectors or lists and prints the correct number when reaching the
  getOption("max.print") limit; partly thanks to a report and
  proposal by Hugh Parsonage to the R-devel list.

• all.equal(<selfStart>, *) no longer signals a deprecation
  warning.

• reformulate(*, response=r) gives a helpful error message now when
  length(r) > 1, thanks to Bill Dunlap's PR#18281.

• Modifying globalCallingHandlers inside withCallingHandlers() now
  works or fails correctly, thanks to Henrik Bengtsson's PR#18257.

• hist(<Date>, breaks = "days") and hist(<POSIXt>, breaks = "secs")
  no longer fail for inputs of length 1.

• qbeta(.001, .9, .009) and similar cases now converge correctly
  thanks to Ben Bolker's report in PR#17746.

• window(x, start, end) no longer wrongly signals "'start' cannot
  be after 'end'", fixing PR#17527 and PR#18291.

• data() now checks that its (rarely used) list argument is a
  character vector - a couple of packages passed other types and
  gave incorrect results.

• which() now checks its arr.ind argument is TRUE rather coercing
  to logical and taking the first element - which gave incorrect
  results in package code.

• model.weights() and model.offset() more carefully extract their
  model components, thanks to Ben Bolker and Tim Taylor's R-devel
  post.

• list.files(recursive = TRUE) now shows all broken symlinks
  (previously, some of them may have been omitted, PR#18296).
