Versioning: Why 1.2?

Asked by Rhett M Osborne on 2012-02-17

Why is libpng 1.2 the version being distributed? I can understand that for legacy support, it may be nice, but those applications really ought to be updated. The main problem I see, however, is that new applications being developed with libpng 1.2 will not compile against libpng 1.5 when people try porting to other platforms. This, of course, depends on their usage of the API, but following the first few links of a google result leads to code which is quite outdated. Furthermore, programs developed using libpng 1.5 compile and link fine with libpng 1.2.

... What does this have to do with my question, though?


I can't find a PPA for the newer version. All I can suggest is yiou either compile it and make a deb file, or report a bug and maybe it will get included in the default repos. It's also at 1.2.46 in Precise.

Can you help with this problem?
