The LOW_MEMORY PNG_COMPRESSION option should not be setting HUFFMAN_ONLY or using a low deflate 'level'; according to the comments in zconf.h only windowBits and memLevel affect the memory. pngwutil.c has been changed to use the same values as HIGH compression. The COMPAT option turned on the old optimize_cmf code (now in fix_cinfo), however there was a serious bug in that code; it put the wrong value in z_cmf. The setting was also not handled correctly in pz_compression_settings. pngtest now verifies the operation of COMPAT and, as a result, pngtest.png has been reverted to the libpng 1.6 (etc) version. IDAT size handling has been improved; if not explicitly set values appropriate to png_level are now chosen (in addition to the handling for the COMPAT setting). HIGH and HIGH_READ_SPEED now create unlimited size IDAT chunks, which requires buffering the whole of the IDAT data in memory but reflects what other programs and optimizers do.
