    ==Bug Fix:==
        * Numerous bugs to do with ordering of glob / job output consistency

= v. 2.0.1 beta4=
    _16/November/2009_
    ==Bug Fix:==
        * Fixed problems with tasks depending on @split

= v. 2.0 beta=
    _30/October/2009_
    With the experience and feedback over the past few months, I have reworked **Ruffus** 
    completely mainly to make the syntax more transparent, with fewer gotchas.
    Previous limitations to do with parameters have been removed.
    The experience with what *Ruffus* calls "Indicator Objects" has been very positive
    and there are more of them. 
    These are dummy classes with obvious names like "regex" or "suffix" which indicate the
    type of optional parameters much like named parameters.

    ==New Decorators:==
        * @split
        * @merge
        * @transform
        * @collate

    ==Deprecated Decorators:==
        * @files_re
          Functionality is divided among the new decorators
            
    ==New Features:==
        * Files can be chained from task to task, implicit dependencies are inferred automatically
        * Limitations on parameters removed. Any degree of nesting is allowed.
        * Strings contain glob letters ``[]?*`` automatically inferred as globs and expanded
        * input and output parameters containing strings assumed to be filenames, whatever the nested data structures they are found in

    ==Documentation:==
        * New documentation almost complete
        * New Simplified 7 step tutorial
        * New manual work in progress

    ==Bug Fix:==
        * Scheduling errors

= v. 1.1.4=
    _15/October/2009_

    ==New Feature:==
        * Tasks can get their input by automatically chaining to the output from one or more parent tasks using the `@files_re`
        * Added example showing how files can be split up into multiple jobs and then recombined
           # Run `test/test_filesre_split_and_combine.py` with `-v|--verbose` `-s|--start_again`
           # Run with `-D|--debug` to test.
        * Documentation to follow

    ==Bug Fix:==
        * Scheduling race conditions

= v. 1.1.3=
    _14/October/2009_

    ==Bug Fix:==
        * Minor (but show stopping) bug in task.generic_job_descriptor

= v. 1.1.2=
    _9/October/2009_
    
    ==Bug Fix:==
        * Nasty (long standing) bug for single job tasks only decorated with `@follows(mkdir(...))` to be caught in an infinite loop

    ==Code Changes:==
        * Add example of combining multiple input files depending on a regular expression pattern. 
           # Run `test/test_filesre_combine.py` with -v (verbose)
           # Run with -D (debug) to test.



= v. 1.1.1=
    _8/October/2009_
    
    ==New Feature:==
        * _Combine multiple input files using a regular expression_
        * Added `combine` syntax to `@files_re` decorators:
        * Documentation to follow...
        * Example from `src/ruffus/test/test_branching_dependencies.py`:
{{{
        @files_re('*.*', '(.*/)(.*\.[345]$)', combine(r'\1\2'), r'\1final.6')
        def test(input_files, output_files):
          pass`
}}}     
        * will take all files in the current directory
        * will identify files which end in `.3`,  `.4` and `.5` as input files
        * will use `final.6` as the output file
        * `input_files  == [a.3, a.4, b.3, b.5]`  (for example)
        * `output_files == [final.6]` 
           
    ==Bug Fix:==
        * All (known) bugs for running jobs from independent tasks in parallel



= v. 1.0.9=
    _8/October/2009_
    
    ==New Feature:==
        _Multitasking independent tasks_
        * In a major piece of retooling, jobs from independent tasks which do not         depend on each other will be run in parallel.
        * This involves major changes to the scheduling code. 
        * Please contact me asap if anything breaks.

    ==Code Changes:==
        * Add example of independent tasks running concurrently in
          `test/test_branching_dependencies.py`
          * Run with -v (verbose) and -j 1 or -j 10 to show the indeterminancy of multiprocessing.
          * Run with -D (debug) to test.

= v. 1.0.8=
    _12/August/2009_
    
    ==Documentation:==
        * Errors fixed. Thanks to Matteo Bertini!

    ==Code Changes:==
        * Added functions which print out job parameters more prettily.
        * `task.shorten_filenames_encoder`
        * `task.ignore_unknown_encoder`
        * Parameters which look like file paths will only have the file part printed
          (i.e. `"/a/b/c" -> 'c'`)
        * Test scripts `simpler_with_shared_logging.py` and `test_follows_mkdir.py`
          have been changed to test for this.


= v. 1.0.7=
    _17/June/2009_
    
    ==Code Changes:==
        * Added `proxy_logger` module for accessing a shared log across multiple jobs in
          different processes.

= v. 1.0.6=
    _12/June/2009_
    
    ==Bug fix:==
        * _Ruffus_ version module (`ruffus_version.py`) links fixed
          Soft links in linux do not travel well
        * `mkdir` now can take a list of strings
          added test case

    ==Documentation:==
        * Added history of changes

= v. 1.0.5=
    _11/June/2009_

    ==Bug fix:==
        * Changed "graph_printout" to `pipeline_printout_graph` in documentation.
          This function had been renamed in the code but not in the documentation :-(

    ==Documentation:==
        * Added example for sharing synchronising data between jobs.
          This shows how different jobs can write to a common log file while still leaveraging the full power of _ruffus_.
        

    ==Code Changes:==
        * The graph and print_dependencies modules are no longer exported by default from task.
          Please email me if this breaks anything.
        * More informative error message when refer to unadorned (without _Ruffus_ decorators) python functions as pipelined Tasks
        * Added Ruffus version module `ruffus_version.py`



= v. 1.0.4=
    _05/June/2009_
    ==Bug fix: ==
        * `task.task_names_to_tasks` did not include tasks specified by function rather than name
        * `task.run_all_jobs_in_task` did not work properly without multiprocessing (# of jobs = 1)
        * `task.pipeline_run` only uses multiprocessing pools if `multiprocess` (# of jobs)  > 1
    
    ==Changes to allow python 2.4/2.5 to run:==
        * `setup.py` changed to remove dependency
        * `simplejson` can be loaded instead of python 2.6 `json` module
        * Changed `NamedTemporaryFile` to `mkstemp` because delete parameter is not available before python 2.6

    ==Windows programmes==
        It is necessary to protect the "entry point" of the program under windows.
        Otherwise, a new process with be created recursively, like the magicians's apprentice
        See: http://docs.python.org/library/multiprocessing.html#multiprocessing-programming
