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

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

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