-Known bugs in libpng version 1.2.7
+Known bugs in libpng version 1.2.20
 
-1. April 22, 2001: pnggccrd.c has been reported to crash on NetBSD when
-   reading interlaced PNG files, when assembler code is enabled but running
-   on a non-MMX i386 platform.
+1. February 23, 2006: The custom makefiles don't build libpng with -lz.
 
-   STATUS: Under investigation.  The change to pnggccrd.c in libpng-1.2.1
-   fixed a problem under FreeBSD but not the problem with NetBSD, which
-   still fails as of libpng-1.2.2rc1.
+   STATUS: This is a subject of debate. The change will probably be made
+   as a part of a major overhaul of the makefiles in libpng version 1.3.0.
+
+2. February 24, 2006: The Makefile generated by the "configure" script
+   fails to install symbolic links
+   libpng12.so => libpng12.so.0.1.2.9betaN
+   that are generated by the custom makefiles.
+
+3. September 4, 2007:  There is a report that pngtest crashes on MacOS 10.
+
+   STATUS: workarounds are
+      1) Compile without optimization (crashes are observed with
+         -arch i386 and -O2 or -O3, using gcc-4.0.1.
+      2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
+         you try to look at it).
+      3) Ignore the crash.  The library itself seems to be OK.
