  10 Release 2a (1998 December)
  11
  12 -- Added functions to convert between 64-bit integers (int64) and all
  13    supported floating-point formats.
  14
  15 -- Fixed a bug in all 64-bit-version square root functions except
  16    `float32_sqrt' that caused the result sometimes to be off by 1 unit in
  17    the last place (1 ulp) from what it should be.  (Bug discovered by Paul
  18    Donahue.)
  19
  20 -- Improved the makefiles.

  23 Release 2 (1997 June)
  24
  25 -- Created the 64-bit (bits64) version, adding the floatx80 and float128
  26    formats.
  27
  28 -- Changed the source directory structure, splitting the sources into a
  29    `bits32' and a `bits64' version.  Renamed `environment.h' to `milieu.h'
  30    (to avoid confusion with environment variables).
  31
  32 -- Fixed a small error that caused `float64_round_to_int' often to round the
  33    wrong way in nearest/even mode when the operand was between 2^20 and 2^21
  34    and halfway between two integers.

  37 Release 1a (1996 July)
  38
  39 -- Corrected a mistake that caused borderline underflow cases not to raise
  40    the underflow flag when they should have.  (Problem reported by Doug
  41    Priest.)
  42
  43 -- Added the `float_detect_tininess' variable to control whether tininess is
  44    detected before or after rounding.
