Changes in this release:

    - New C++ compilers: IBM xlf, HP aCC, HP CXX, Intel fortran compiler.
    - New tools: Qt4 support, MS message compiler and IDL compiler.
    - New main targets: 'notfile' and 'cast'.

    - Core changes:

        - Only one file required at top level of a project, named Jamroot.
        - Jamfiles can now contain project-specific help messages.
        - "Indirect conditional requirements" introduced
          (http://tinyurl.com/mn3jp)
        - Strip suffix in main target names when computing names of generated 
          files (URL) 
        - The 'source-location' project attribute can contain 
          several directories.
        - Usage requirements are propagated not only direct dependents, 
          but to indirect dependents.

    - Command line option changes (see http://tinyurl.com/zbycz)
        - New option --build-dir
        - The --clean option cleans only target below the current directory,
          not globally. 
        - New --clean-all option was added.
        - New option --debug-building
        - Running "bjam some_directory" works even if there's no Jamfile 
          in the current directory.

    - Toolset improvements:
        - Assembling support with gcc, borland and msvc.
        - Support amd64/ia64 cross-compiling with msvc.
        - Improved, registry-based autodetection for msvc.
        - Serialize execution of gcc.link actions  
        - Precompiled headers supported on MSVC 
          (Need documentation)

    - New features <warnings> and <warnings-as-errors>           
    - The 'glob' rule accepts wildcards in directory names.
    - The 'stage' rule was renamed to 'install' 
      (the old name still available for compatibility)
    - The <tag> feature can accept user-defined function as value
      (URL)
    - The 'install' rule can install a directory hierarchy preserving relative
      paths.
    - The 'install' rule no longer allows to change library 
      name during install.
    - The Jamfile referred via 'use-project' may declare project id different
      from the one in 'use-project'.
    - The 'using' rule now searches the directory of containing Jamfile.
     

The following bugs were fixed:

    - The <library> feature was ignored for static linking
    - Fix #include scanning for C files.
    - Child projects were sometimes loaded before parent projects.
    - Fix project references with absolute paths on Windows. 
    - The <dependency> feature was ignored for 'install' targets.
    - A generator having the same type in sources and targets was causing
      hang.
    - Use 'icpc' command for Intel, fixing errors with 8.1 and higher. 
    - Generation of PS files with the FOP tool really produces .PS files.
    - No dependency scanning was done for C files.
    - The 'constant' and 'path-constant' rules did not accept multi-element
      value.
    - Don't pass -fcoalesce-templates to gcc on OSX 10.4
    - Fix static lib suffix on OSX.
    - Fix rpath setting on Intel/Linux.
    - The 'install' rule don't unnecessary scans #includes in installed
      headers.
       

Developer visible changes:

    - Ability to customize type's prefix depending on build properties.
    - Generator's 'run' method can return usage-requirements.  
    - Main target rule is automatically declared for each new target type.
    - 'Link incompatible' feature attribute was removed
    - Generators no longer bypass unhandled sources, they just ignore them.
    - If there are several applicable generators, immediately report
      ambiguity.
      Provide a way to explicitly resolve conflicts between generators.
    - The 'flags' rule can match absense of feature.
    - Great improvement in response files handling
    - The 'toolset.flags' rules allows value-less feature to signify
      absense of this feature (fix hack-hack).
    - Automatically declare main target rule for each declared target type.
    - When inheriting types, inherit generators for the base type, as opposed
      to using various hacks to invoke base generators when needed.
    - Improve diagnostic for "duplicate actual target" and generator
      ambiguity.
