[Phil Carns]

The official Darshan 2.2.6 release is now available on the Darshan web 
site (http://www.mcs.anl.gov/darshan), and the online documentation has 
been updated accordingly.  This release includes performance 
enhancements as well as various minor bug fixes and compatibility 
improvements.

darshan-2.2.6
=============
* Bug fixes:
   - make sure to honor user-specified hints passed in at runtime
     via the DARSHAN_LOGHINTS env variable.
   - include fread and fwrite in darshan-job-summary.pl read and write 
counts
   - fix segmentation fault on invalid arguments to darshan-parser
* Performance enhancements:
   - collect mount point information at rank 0 and broadcast to all
     processes to avoid excess file system traffic on startup
   - change default MPI-IO hints for writing log file to
     romio_no_indep_rw=true and cb_nodes=4 to improve log creation 
performance
* Install libdarshan-util and headers during installation process for
   darshan-util; patch contributed by Matthieu Dorier
* Detect PMPI support at link time when using compiler scripts produced
   by the darshan-gen-* utilities.  This avoids link problems when Darshan
   compiler wrappers are used with the ADIOS dummy MPI library; reported
   by Jingqing Mu
* Support MPICH_{CC/CXX/F77} environment variables in compiler scripts
   produced by the darshan-gen-* utilities
* Add instrumentation of startup time, enabled via DARSHAN_INTERNAL_TIMING
   environment variable
* Rename cp-shutdown-bench test utility to darshan-shutdown-bench and enable
   benchmarking hooks in library by default so that darshan-shutdown-bench
   can be used with any Darshan installation
* Remove deprecated --enable-st-dev-workaround configure option
* Misc. documentation updates
