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

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

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