We have continued to shake out bugs in the "big variable" file format. (See NewFileFormatDefinition for technical details and NewFileFormatCode for usage. Thank Kui Gao from Northwestern University for doing a lot of the work). Thanks to our friends at PNNL for giving the "big variable" format a good shakedown before the final release.

We introduced a new optimization in parallel-netcdf with this release. If the hint "striping_unit" is set, then pnetcdf will align the start of non-record variables to a multiple of that value. See StripingUnitHint for more information.

The 'ncgen' utility can now create "big variable" (CDF-5) files, in addition to the older "big file" (CDF-2) files.

We did some other stuff, too. Still need to go through the svn logs.
