Changes since 2.21.1
--------------------

3/10/10
    - Added optional input arg to bpver() to trigger return of
      entire version struct with Name, Version, Release and Date just
      like MATLAB's ver() function.

12/24/09
    - Released new builds as version 2.21.1d.
        

11/4/09
    - Removed unnecessary 'return' statement at end of all M-files. If
      anything it should be an 'end' statement, but even that is
      optional, so we just let functions get terminated by the
      end-of-file or another function declaration.

4/1/09
    - Build 02
    - Updated calls to obsolete MEX functions:
        mxCreateFull -> mxCreateDoubleMatrix
        mxIsString   -> mxIsChar
        mxIsFull     -> !mxIsSparse
      to build version for MATLAB R2009a (7.8).

4/10/08
    - Rebuilt version for Mac OS X (Intel) using gfortran instead of g95.
      Fixes issue where, after running the MEX file, MATLAB would die after
      about 10 minutes with the error "Alarm clock". Internally tagged as
      version 2.21.1c.

9/21/07
    - Added builds of 2.21.1 for the following architectures:
        Mac OS X (Intel)
        Windows for MATLAB R2006b (MATLAB 7.3) and later
        Linux x86 for MATLAB R2007a (MATLAB 7.4) and later
      Internally tagged as version 2.21.1b.


Changes since 2.21
------------------

2/2/05
    - Released version 2.21.1.

1/25/05
    - Changed the default option for TFEAS2 from 1e-7 to 1e-6.

1/11/05
    - In bpopt.m, turned off presolve option to "aggregate, to eliminate
      free variables" to fix DC OPF bug.

1/6/05
    - Added bpver.m to print version information.
    - Corrected the version information printed by MEX file in verbose mode
      (version 2.21 of the MEX interface incorrectly claimed to be version 2.20
       of the BPMPD solver).


Version 2.21
