Hi list, libpng15 can be found in graphics project, feel free to test build with your packages. Details about api changes can be found in [1]. I would like quote only one paragraph from this document: " There are no substantial API changes between the non-deprecated parts of the 1.4.5 API and the 1.5.0 API, however the ability to directly access the main libpng control structures, png_struct and png_info, deprecated in earlier versions of libpng, has been completely removed from libpng 1.5. " Be sure I don't know now when will libpng15 become the default in the Factory, another mail will precede this change. Thanks for any comment on this, Petr [1] http://www.libpng.org/pub/png/src/libpng-1.4.x-to-1.5.x-summary.txt
