Thanks for this data. To add some relevant information:
* only the 191 symbols of the final line are stable symbols that
are part of the API, and which stability is guaranteed across
upgrades;
* the 125 removed symbols in 1.2.8rel-2 are from private functions
that are not part of any header and not used by any software;
* the 6 symbols that were removed in 1.2.8rel-2 and added back in
1.2.8rel-4 are part of the so-called "internal" libpng API, used
by broken software like OptiPNG and pngcrush; I've added them
back to keep backwards compatibility, and upstream developers of
these software are considering to ship private copies of these
functions (no, I don't want to argue which of these evils is the
worst); this is why upstream doesn't ship them anymore in the
latest version;
* the 7 symbols that were removed in 1.2.8rel-2 then added in
1.2.13 are probably symbols that used to be private and which
are now part of the API;
* as for the two top lines, I have no idea.
