xlPrecision 3.1.7 and 2017b are released. These versions fix bugs in xlpCOS and xlpACOS. When the input for xlpCOS was 0, or so close to 0 that for the maximum significant digits in effect it would return the same result as 0, xlpCOS returned 0 instead of 1. When the input for xlpACOS was within 0.000000000000001 of 0, 1, or -1, xlpACOS returned pi/2, 0, or pi respectively, as if the input was exactly 0, 1, or -1.

xlPrecision 2017 is released. Read about the new features in xlPrecision 2017 here.

The Free Edition has not yet been updated to 2017. Until then, unless xlPrecision 2017 is specifically requested, xlPrecision 3.1.6 will still be sent to customers who buy xlPrecision. This is in order to avoid requiring an additional manual step during installation (xlPrecision 2017 requires a new xlPrecision.xla file). Once the Free Edition has been upgraded to xlPrecision 2017, paying customers will get xlPrecision 2017 automatically.
