   - improve wording and display of error when required value is
     missing 

   - fix templates not able to see all classes available on
     classpath

   - removed all forms of throttling of R sessions (should now be

     job cancelled via bpipe stop (causing outputs not to be
     cleaned up)

   - Added "checks" command and "override" command to display and

========== Changes for Bpipe Version 0.9.8.6_beta_1 ============

   - fixed file(...) function sometimes returning file object
     for "<file>/." 

   - experimental feature: supply closure with ".using(...)" for lazy

     configuration of pipeline stages

   - initial implementation of a 'bpipe status' command, to show exactly
     what is currently running 

   - Ability to explicitly cause a
     branch to either fail or succeed prematurely 
     (via "fail" and "succeed" commands) 

   - added support to transform a

   - ability to configure and customize reports from bpipe.config 
     (custom names, etc.), and to send by email when email notifications
     configured

   - more graceful / better handling of errors
     that cause the script to not parse or load at all 

   - support for finding bpipe.config in the same directory as
     the pipeline script (which might be different to the
     directory that bpipe is running in) 

   - better handling of exception when probing tools in tool database 

   - new feature: allow for muliply by Map to set an explicit
     mapping of branch names to inputs 

   - special behavior for accompanies when dealing with 
     transforms: always adds
     extension to end of file rather than replacing 

   - allow requires to specify complete file name instead of just
     extension 

   - allow resolution of 'load' files relative to the pipeline
     script itself so that it is easy to maintain a pipeline
     file and ancillary files in the same directory 

========== Changes for Bpipe Version 0.9.8.5 ============

-   fix output.dir not working if transform annotation used 

-   fix silly mistake causing load external stages to fail

    fix not seeing it in dependency graph

-   better file names when output extension occurs in combination with 
    introduction of branch name (foo.chr1.csv instead of foo.txt.chr1.csv)
    NOTE: in rare situations this might cause output file names to change,
    thus may cause outputs to get recomputed for existing pipelines (in rare cases)

-   allow command line region to override chr() within pipeline

-   fix command configuration sometimes not displaying name 

-   slightly better description of command for specifying report 
    template (see Google Group discussion)

    trace

========== Changes for Bpipe Version 0.9.8.4.1 ============

-   fix middle parallel section causing spurious error if no inputs provided
    at start of pipeline

     command log instead of real value of $thread

-    prevented tools being probed more often than needed

     class, applied throttling to tool probing so as to lessen chances
     of exhausting threads or file handles when running with 
     large numbers of inputs and highly parallel pipelines

-    fix log.warn causing any UNKNOWN status code return
     from PBS/Torque to exit with error instead of retrying

-    fix filter transforms sometimes basing output file
     on wrong input 

-    preliminary SLURM support via Andrew Lonsdale (thanks!)

-    when a command is configured with to use a specific
     number of procs, that should override the magic $threads
     variable value

     when in explicitly set output folder

-    fix "using" construct causing diagrams to fail

     line

-    show all commands when test mode aborts a multi
     command

-    option to show only output from single thread with
     bpipe log -t

-    fix input not resolved by from / input ext when
     reference embedded in nested

-    fix %bin% expansion incorrect when tool command is
     part of the full path containing the tool itself - eg:
     /usr/local/bwa/bwa-0.5.9/bwa

-    fix possible double period in output file name (regression)

     situation that no inputs were provided

-    fix transform producing same output as input when
     output file of same type as input

-    add support for closure as value for variable default
     to compute default value at runtime, prevent referencing  
     unless actually needed (useful eg: if the default should be 
     an input when not provided)

-    attempt to fix out-of-order execution of pipelines
     that start with list and append stages after

-    support for "requires" to specify required parameters

    not using split files as basis for outputs sometimes

=========== Changes for Bpipe Version 0.9.8_beta_4 ============

-   support for multiple split characters in input matching patterns

-   support for config closure to enable config across multiple commands or
    when using "multi"

-   slightly better messaging when skipping command due to existence, not
    based on time stamp

-   fix display of output to stderr when version probe command fails
    - send to log instead

-   experimental chaining of from and filter / transform

-   fix "from" causing original inputs not to be queried for files in some
    situations

-   fix "filter" nested in "from" failing to infer correct output when output 
    based on input other than input in "from" clause

-   fix possible exception when using $output.prefix

-   fixed second and later stages in nested parallel segments not always
    resolving correct inputs

-   fix attempts to use "split" in input variables failing (regression)

-   added support for use of "region" variable without genome or chr splitting
    to allow generic pipeline stages that can work with or without regions 
    specified
    
-   added command line option ("-L") to specify default value of region variable
    
-   fixed "from" to match multiple inputs if used in form from("*.txt") etc.

-   Added example for how to run paired end reads

-   fix output extension causing wrong / confusing behavior when incombination
    with a filter and unexpected input order

-   fix bpipe command leaving out eclipse folder from classpath

=========== Changes for Bpipe Version 0.9.8_beta_3 ============

-   Updated underlying groovy implementation to Groovy 2.1

-   Add "pre-existing" label to display of outputs that 
    weren't genereated by the current run

-   fix error when creating File objects from input /
    output

-   support for using numbered outputs with file extensions
    (eg: $output2.txt)

-   fixed outputs sometimes being recreated unnecessarily
    when multiple commands inside transform/filter

-   support for implicit 'thread' variable for auto
    allocating threads based on known concurrency

-   fixed duplicate output files for $output1,
    $output2,... if pipeline has no input files

-   fix jobs not always cleaned up from global job table

-   support for referencing a particular input with a
    particular extension using "$input<n>.<ext>"

-   fixed double period appearing in some file names when
    using filter

-   fixed order of output from "glob" depending on the
    vagaries of the file system or java internals by
    sorting it

-   made 'from' conform to the convention of multiple
    inputs of same time bumping to next actual input
    instead of returning the same over and over

=========== Changes for Bpipe Version 0.9.8_beta_2 ============

-   fixed multi not failing pipeline when an asynchronous
    command fails

-   making filter() conform to the same behavior as
    transform(): when a filter type is repeated, it moves
    to the next input (see google group discussion -
    https://groups.google.com/forum/?fromgroups=#!topic/bpipe-discuss/G58ExlG2Vgo

-   fixed error when reporting notification failures
    to user

-   fixed output extensions not working correctly with
    filter when multiple filters supplied

-   fix multi not actually parallelizing properly in
    some cases

-   fix regression in 'from' not accepting list (added
    test)

-   fixed from with multiple arguments ignoring first
    argument

-   fixed deadlock condition in using "multi" in certain
    cases

=========== Changes for Bpipe Version 0.9.8_beta_1 ============

-   More flexible model for concurrency management, enabling
    management of any kind of resource. Introduction of
    new keyword "uses" to declare resource usage for a block
    and command line options (-m, -l, -n) to control different
    aspects of concurrency

-   Complete re-implementation of dependency analysis so that
    Bpipe understands the depedency graph and can perform
    transitive dependency analysis to allow rerunning piplines
    without rebuilding unnecessary intermediate dependencies.
    (See Issue #2, http://code.google.com/p/bpipe/issues/detail?id=2)
    Includes support for new command line commands, 
    "bpipe query", "bpipe cleanup", and "bpipe preserve" to 
    display and manage dependencies, as well as annotations,
    "@preserved" to declare dependencies that should not be
    deleted in a "cleanup". 

-   support for new 'glob' function available within
    pipeline stages to facilitate pipelines that need to
    use wild card matches on input files.

-   Annotations can be used with lower case now. Upper case 
    still works, but some people feel @transform, @filter,
    etc. looks nicer.

-   Support for parallelizing by chromosome on existing
    files already split by chromosome. If your input files
    are split and named by chromosome, you can use 
    filterInputs parameter to make the existing
    files be used for inputs to the parallelization 
    eg. chr(1..2, filterInputs:true) 

-   Many various bug fixes and improvements to messaging,
    behaviour and output.
