 Darshan-3.1.3-pre1
 =============
+* add new DxT instrumentation modules to provide fine-grained read/write
+  operation tracing at both the POSIX and MPI-IO layers
+    - this functionality should be enabled at runtime by exporting the
+      DXT_ENABLE_IO_TRACE environment variable
+    - trace output is stored within Darshan's traditional log file format
+    - a corresponding trace parser (darshan-dxt-parser) is offered within
+      darshan-util to allow the DxT trace modules to be parsed and displayed
+    - this software was contributed by Cong Xu and Intel's HPDD division.a
+* add logic to allow Darshan to capture command line arguments from Fortran
+  applications (contributed by Cristian Simarro)
 * skip instrumentation attempts for anonymous mmap() calls; this avoids a
   potentential deadlock condition when used with hugepages on Cray systems.

   vary the wrapper prototypes to match the corresponding HDF5 library ABI.
   The initial patch for HDF5 1.10 compatibility was contributed by 
   Karl-Ulrich Bamberg.
+* modified Darshan's path exclusion logic to include a whitelist to prevent
+  I/O to/from Cray's Datawarp service from being filtered out (it is located
+  within the /var directory, which historically has been excluded). Reported
+  by Glenn Lockwood.
