10Release 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.

23Release 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.

37Release 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.
