Making otm 8.9 took some more time than planned. An important reason is that the development team is getting older (62–70+) and hence a little more vulnerable. Hartmut, one of the four team members in particular indispensable for complexities such as the ot Layout features subsetting, became serious ill a few years ago and could not work at all since then.

End of October 2021 dtl’s founder Frank had a heart attack and therefore open-heart surgery, which resulted in five bypasses. Moreover, because it is so advanced, otm is not an easy and far from cheap application to develop. It is probably no coincidence that there is not a directly comparable tool for macOS, Windows, and Linux on the market.
