  1. Hardware read-only support for SD Cards. Make sure to read the hints and
    constraints in doc/contraints.txt. To directly test the hardware without
    using the new Monitor libraries, use test_programs/sdcard.asm

  2. Software read-only support for FAT32 (new Monitor Libraries sd_library.asm
    and fat32_library.asm).

  3. Monitor: It is now possible to browse directories and to load/run files
    directly from the monitor. Partition #1 of the SD Card is automatically
    mounted when using directory or file related functions.
    New top level folder "qbin" contains demo programs that can be executed.

  4. C Compiler, Standard C Library: VBCC toolchain including VBCC compiler,
    VASM assembler and VLINK linker: Stable basic C environment including
    file system access (via fopen, fread, ...) and including convenient
    editing functions due to the fact, that the Monitor's new versatile
    gets_slf() function is used when reading from stdin. Everything is
    located in the "c" subfolder.

    Partition 1 of the SD Card is automatically mounted on-demand (upon first
    call of fopen). To test it, try c/test_programs/fread_basic.c

    Monitor library is available, that wraps monitor functions. To test it, try
    c/test_programs/shell.c

  5. EAE: Extended Arithmetic Element added: This is a 16-bit signed/unsigned
    integer multiplication (with 32bit results), division and modulo
    co-processor. An example of the impressive speedup can be seen in the
    source code comments of mandel_perf_test.asm, which shows a speedup of
    factor 4.5 compared with release version 1.3.

    For testing it, use the following programs:
    test_programs/eae.asm
    test_programs/32bit-mul.asm

  6. Further Library enhancements:

    • IO Library (Monitor): New gets function that supports CR or LF or CR/LF
      for ending the editing and that supports backspace (BS). New get_s that
      only function that reads until the buffer is full. get_slf that adds a LF
      in case the string input is ended by CR, LF or CR/LF.
    • Math Library (Monitor): mulu, muls, divu, divs, mulu32, divu32
    • String Library (Monitor): chr2lower, split, h2dstr
