===================================
Library
-------
+ - Fixed a file space allocation bug in the parallel library for chunked
+ datasets
+
+ With the addition of support for incremental file space allocation for
+ chunked datasets with filters applied to them that are created/accessed
+ in parallel, a bug was introduced to the library's parallel file space
+ allocation code. This could cause file space to not be allocated correctly
+ for datasets without filters applied to them that are created with serial
+ file access and later opened with parallel file access. In turn, this could
+ cause parallel writes to those datasets to place incorrect data in the file.
+
- Fixed an assertion failure in Parallel HDF5 when a file can't be created
due to an invalid library version bounds setting
