| 4 | This is not intended to be a public release. It will be replaced |
| 5 | within a few weeks by a public version or by another test version. |

| 7 | Changes since the last release: |
| 8 | |
| 9 | Optimized Paeth calculations by replacing abs() function calls with intrinsics |
| 10 | plus other loop optimizations. Improves avg decoding speed by about 20 percent. |
| 11 | Commented out i386istic "align" compiler flags in makefile.lnx. |
| 12 | Reduced the default warning level in some makefiles, to make them consistent. |
| 13 | Removed references to IJG and JPEG in the ansi2knr.c copyright statement. |
| 14 | Fixed a bug in png_do_strip_filler with XXRRGGBB => RRGGBB transformation. |
| 15 | Added grayscale and 16-bit capability to png_do_read_filler(). |
| 16 | Fixed a bug in pngset.c, introduced in version 0.99c, that sets rowbytes |
| 17 | too large when writing an image with bit_depth < 8 (Bob Dellaca). |
| 18 | Corrected some bugs in the experimental weighted filtering heuristics. |
| 19 | Moved a misplaced pngrutil code block that truncates tRNS if it has more |
| 20 | than num_palette entries -- test was done before num_palette was defined. |
| 21 | Fixed a png_convert_to_rfc1123() bug that converts day 31 to 0 (Steve Eddins). |
