In release 0.9.3, I tried to fix the nasty Float(s) lost errors. Unfortunately, my fix in that release worked well on the minimal examples I had at that time, but failed on other documents (and made some documents which compiled well before to now exhibit Float(s) lost...) So I had to delete release 0.9.3.
We now use the cool cuted package for laying out our figure series, which turned out to be quite robust. I can no longer find a way to make the package throw Figure(s) lost. Thus, I think we are getting closer to have good solution for automatic page-breaking of series of figures. This new release marks this point of our work.
The only errors left that I can generate are some
! Dimension too large.

errors, which are probably rooted in too-large sub-figures or too-long series.
