===================================
Library
-------
+ - Fixed potential buffer overrun issues in some object header decode routines
+
+ Several checks were added to H5O__layout_decode and H5O__sdspace_decode to
+ ensure that memory buffers don't get overrun when decoding buffers read from
+ a (possibly corrupted) HDF5 file.
+
+ (JTH - 2023/04/05)
+
+ - Fixed issues in the Subfiling VFD when using the SELECT_IOC_EVERY_NTH_RANK
+ or SELECT_IOC_TOTAL I/O concentrator selection strategies
+
+ Multiple bugs involving these I/O concentrator selection strategies
+ were fixed, including:
+
+ * A bug that caused the selection strategy to be altered when
+ criteria for the strategy was specified in the
+ H5FD_SUBFILING_IOC_SELECTION_CRITERIA environment variable as
+ a single value, rather than in the old and undocumented
+ 'integer:integer' format
+ * Two bugs which caused a request for 'N' I/O concentrators to
+ result in 'N - 1' I/O concentrators being assigned, which also
+ lead to issues if only 1 I/O concentrator was requested
+
+ Also added a regression test for these two I/O concentrator selection
+ strategies to prevent future issues.

- Memory leak
Memory leak was detected when running h5dump with "pov". The memory was allocated
