Darshan-3.0.0-pre1
=============
<span style="color: #000000;background-color: #ddffdd">+* new version of Darshan with the following features/improvements:
+ - hooks for developers to add their own instrumentation module
+ implementations to capture new I/O characterization data
+ - these instrumentation modules can be used to instrument new
+ I/O interfaces or gather system-specific parameters, for instance
+ - modularized log format allows new module-specific utilities to
+ access their I/O characterization data independently
+ - this new format also allows new counters to be added to existing
+ instrumentation modules without breaking existing utilities
+ - Darshan logs now contain a mapping of Darshan's unique record
+ identifiers to full file names, instead of fix-sized file name
+ suffixes
+ - a new instrumentation module for capturing BG/Q-specific parameters
+ (BG/Q environment is automatically detected at configure time)
+ - new darshan-parser and darshan-job-summary output to utilize the
+ new modularized log format
+* updated documentation outlining changes in this release, as well as
+ steps for adding new instrumentation modules is given in the top-level
+ 'doc' directory.
+ - documentation for configuring and using the darshan-runtime and
+ darshan-util components are mostly the same and still located in
+ their respective directories ('darshan-runtime/doc' and 'darshan-util/doc')
