SIGNIFICANT USER-VISIBLE CHANGES:
* All packages are by default byte-compiled on installation. This
makes the installed packages larger (usually marginally so) and
may affect the format of messages and tracebacks (which often
exclude .Call and similar).
NEW FEATURES:
* factor() now uses order() to sort its levels, rather than
sort.list(). This allows factor() to support custom vector-like
objects if methods for the appropriate generics are defined. It
has the side effect of making factor() succeed on empty or
length-one non-atomic vector(-like) types (e.g., "list"), where
it failed before.
* diag() gets an optional names argument: this may require updates
to packages defining S4 methods for it.
* chooseCRANmirror() and chooseBioCmirror() no longer have a
useHTTPS argument, not needed now all R builds support https://
downloads.
* New summary() method for warnings() with a (somewhat
experimental) print() method.
* (methods package.) .self is now automatically registered as a
global variable when registering a reference class method.
* tempdir(check = TRUE) recreates the tempdir() directory if it is
no longer valid (e.g. because some other process has cleaned up
the /tmp directory).
* New askYesNo() function and "askYesNo" option to ask the user
binary response questions in a customizable but consistent way.
(Suggestion of PR#17242.)
* New low level utilities ...elt(n) and ...length() for working
with ... parts inside a function.
