NEW FEATURES:

• The internal method of unzip() now follows unzip 6.00 in how it
  handles extracted file paths which contain "../". With thanks to
  Ivan Krylov.

INSTALLATION:

• Standalone nmath can be built with early-2025 versions of
  clang-based compilers such as LLVM clang 20, Apple clang 17 and
  Intel icx 2025.0.

• Tcl/Tk 9 can be used to build package tcltk: this has become the
  default in some Linux distributions. N.B. several third-party
  packages currently require Tcl/Tk 8 or even 8.6 without declaring
  so.

BUG FIXES:

• Java detection in javareconf could not detect libjvm.* in the
  zero variant of the JDK (PR#18884). All valid variants as of JDK
  24u are now supported.

• factanal(.., rotation=*) now correctly updates rotmat, fixing
  PR#18886.

• dnbinom(<large>, <muchlarger>, ..) now is 0 correctly, instead of
  NaN or Inf sometimes.

• dbinom(<large>, n=Inf, ..) is 0 now correctly, instead of NaN
  which also fixes many dnbinom() cases, notably those mentioned in
  PR#16727 comment wch#5.

• Fixing C level “binomial deviance” bd0() for extreme arguments
  (preventing under-/overflow) solves more PR#16727 cases and also
  prevents some full accuracy loss in such cases for dbinom(),
  dnbinom(), and via dbinom_raw() potentially dgeom(), dhyper(),
  dbeta(), and df().

• signif(1.**e308, digits) no longer truncates unnecessarily (but
  still to prevent overflow to Inf), fixing PR#18889.

• prettyNum(*, zero.print={>=1-char}, replace.zero=TRUE) now works
  as documented, thanks to Marttila Mikko and Ivan Krylov's
  messages on R-devel.

• pbeta(x, a,b, ..) for very large a,b no longer returns NaN but
  the correct values (0 or 1, or their logs for log.p = TRUE).
  This improves Mathlib's C level bratio() and hence also
  pnbinom(), etc..
