Hi! I think what you're spotting is that I made a mistake in updating the library revision in the past, and failed to reset CURRENT (or bump AGE).
We are at least 99.9%-compatible with .so.10 / 0.9.37, but there _may_ have been some minor reason to bump the .so-level, not entirely sure which of the two mistakes I made in retrospect. Regardless, the only sane way forward at this point is to continue to stick to the libtool rules, as one cannot sanely go back to .10-levels, or to .12.0. Naturally, when we go to .13, we should definitively make sure to reset CURRENT properly. Happy hacking!
