CHANGES IN R 4.5.1:

  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 #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..
