  - Fixed issue where global config file would override command line arguments.

    This also ensures that in the absence of data, its output is not treated as

    --ws-url.
  - Added the request query string to the W3C format.

  - Improved parsing of operating systems.
  - Refactored log parser so it allows with ease the addition of new modules.
    This also attempts to decouple the core functionality from the rendering
    functions. It also gives the flexibility to add children metrics to root
    metrics for any module. e.g., Request A was visited by IP1, IP2, IP3, etc.
  - Restyled HTML output.

    code 444 as 404.
  - Added --4xx-to-unique-count command line option to count client errors (4xx)
    to the unique visitors count.  Now by default it omits client errors (4xx)
    from being added to the unique visitors count as they are probably not welcomed
    visitors. 4xx errors are always counted in panels other than visitors, OS &
    browsers.
  - Added and updated operating systems, and browsers.
  - Added excluded IP hits count to the general statistics panel on all reports.
