This release fixes a major bug which we only noticed the other day, but which apparently had been in NarraFirma from the beginning. Deep in the code, an accessor returned the value of a field. While checking to see if the stored value existed, the code mistakenly returned a blank string if the value happened to be exactly zero. This error has now been fixed, but this means that on every histogram drawn (and every statistical test run) before version 1.2.6 of NarraFirma, all scale values that were exactly zero were ignored.
We were very upset to discover this mistake, and we heartily apologize for never having noticed it before.
Most graphs will not have been affected much by this error, since it is rare to collect huge numbers of zero scale values. However, please be aware that it is possible, if you load an older project into version 1.2.6+ of NarraFirma, that a histogram (and its statistical test results) could change.
