    … …  
    1618   * Shortened coarse CFO estimation window to 64 samples, to avoid corruption when the channel delay spread is non-zero
    1719   * Moved the Tx scaling after the interpolation filters, so filter outputs (not inputs) can be saturated before transmission
     20   * Fixed (very old) bug with 64-QAM packets of certain lengths being declared bad
     21   * Fixed phase error tracking system to handle wrapping phase error; can now track larger CFO in frequency domain
     22   * Added pseudo-random payload generator
    1823
    1924'''Software Changes'''
    … …  
    2328  * Updated with new PHY registers and options
    2429  * Added mode to generate traffic locally, emulating a fully-backlogged data source
    25   * All 32 packet buffers are filled with random bytes in warpmac_init() for fairer tests with locally generated packets
    2630 * CSMAMAC:
    2731  * Updated to use PHY's auto response to automatically transmit ACKs
