I see the series a 1.0, 1.2, 1.5…
That is 1.2.50: > dam@unstable10s [unstable10s]:/home/dam > pkginfo -x CSWlibpng3 CSWlibpng12-0 > CSWlibpng15-15 > CSWlibpng3 libpng3 - The official library for Portable Network Graphics > format (PNG), libpng.so.3 > (sparc) 1.2.50,REV=2012.09.18 > CSWlibpng12-0 libpng12_0 - The official library for Portable Network > Graphics format (PNG), libpng12.so.0 > (sparc) 1.2.50,REV=2012.09.18 > CSWlibpng15-15 libpng15_15 - The official library for Portable Network > Graphics format (PNG), libpng15.so.15 > (sparc) 1.5.13,REV=2012.11.10 libpng.so.3 and libpng12.so.0 are produced by the same recipe: https://buildfarm.opencsw.org/source/xref/opencsw/csw/mgar/pkg/libpng/branches/libpng3/Makefile This seems like the same library due to upstream rename. > On my own box I and up having libpng3..

If you don’t introduce another soname it should be fine, otherwise the same restrictions apply as to e.g. the OpenSSL transition: http://wiki.opencsw.org/project-openssl Although it should be less of a problem now due to direct linking, but AFAIK this has not been tested enough.
