[Phil Carns]

Darshan 2.2.8 is now available for download on the Darshan web site.  
This release contains a number of bug fixes for problems recently 
reported on the mailing list.  It also includes a few new tools for 
splitting up Darshan logs based on files opened by the application.  The 
full change log is listed below:


darshan-2.2.8
=============
* WARNING: please note that the Darshan module file for Cray 
environments has
   been updated, especially in the DARSHAN_POST_LINK_OPTS variable.  Please
   update your module file accordingly when upgrading from 2.2.7 or earlier
   on Cray platforms.
* Improved ability to analyze I/O activity related to particular files
   opened by an application
   - darshan-summary-per-file.sh script to generate a separate pdf 
summary for
     each file opened by an application. Developed by Rob Latham.
   - Added --file-list and --file-list-detailed options to darshan-parser to
     list files opened by an application along with brief statistics
   - Added --file option to darshan-convert to filter out activity for a
     specific file from a Darshan log
* Add wrappers for POSIX AIO operations (fixes tracking of underlying POSIX
   operations resulting from nonblocking MPI-IO operations. Bug reported by
   David Shrader.)
* Fix compile-time errors when Darshan is configured for use with MPICH 3.x
   installations with const correct MPI function prototypes. Also affects
   MPICH 1.5+ installations with optional const support. Reported by 
Yushu Yao.
* Fix segmentation fault when using LD_PRELOAD instrumentation on programs
   that use MPI_Init_thread() rather than MPI_Init(). Reported by Myriam
   Botalla.
