+New Features
+============
+
+    Configuration
+    -------------
+    - Added a configuration option to change the default plugin path.
+      The configure option is --with-default-plugindir=location.
+      The cmake option is -DH5_DEFAULT_PLUGINDIR:PATH=location.
+      HDFFV-8513.  (ADB 2013/09/04)
+    - Renamed FFLAGS to FCFLAGS in configure. (ADB 2013/08/13)
+    - CMake can now package a compressed examples file, the default for 
+      Windows binaries from HDF Group.  (ADB  - 2013/07/22)
+    
+    Library
+    -------
+    - None
+ 
+    Parallel Library
+    ----------------
+    - None
+ 
+    Tools
+    -----
+    - h5repack: Added the ability to use plugin filters to read and write 
+              files. The option uses the filter number. HDFFV-8345 
+              (ADB - 2013/09/04).
+    - h5dump: Added the option -N --any_path, which searches the file for 
+              paths that match the search path. HDFFV-7989 (ADB - 2013/08/12).
+    - h5dump: Added the optional arg 0 to -A, which excludes attributes 
+              from display. HDFFV-8134 (ADB - 2013/08/01).
+
+    High-Level APIs
+    ---------------
+    - None
+
+    Fortran API
+    -----------
+    - None
+
+    C++ API
+    -------
+    - Added tutorial examples to C++/examples.  They can be installed by
+      "make install-examples" and, in the installed directory, they can be
+      executed by running the script file run-c++-ex.sh. (BMR - 2013/09/28)
+    - A new class, H5::H5Location, is added to represent the location concept
+      in the C library.  It is a base class to H5::H5File and H5::H5Ojbect,
+      whose member functions are moved into H5::H5Location.  H5::H5File can
+      now inherent those functions.  As a result, an H5::H5File object can have
+      an attribute. (BMR - 2013/09/27)
+    - Added wrappers for H5Rget_obj_type2 to retrieve the type of the object
+      that an object reference points to. (BMR - 2013/09/27)
+	H5O_type_t H5Location::getRefObjType(void *ref, H5R_type_t ref_type)
+    - Added wrappers for H5Aexist to check whether an attribute exists given
+      a name. (BMR - 2013/09/27)
+	bool H5::H5Location::attrExists(const char* name)
+	bool H5::H5Location::attrExists(const H5std_string& name)
+    - Added a number of overloaded functions for convenience. (BMR - 2013/09/27)
+
+
+Support for New Platforms, Languages, and Compilers
+===================================================
+    - None
+
+Bug Fixes since HDF5-1.8.11
+===========================
+
+    Configuration
+    -------------
+    - Modified H5detect.c to scan floating point types for padding bits before
+      analyzing the type further.  This should fix problems with gcc 4.8. 
+      (NAF - 2013/09/19 - HDFFV-8523/HDFFV-8500)
+    - HDF5 rpaths are no longer encoded in the library files when configured
+      with --disable-sharedlib-rpath. (LRK-2013-09-23 - HDFFV-8276)
+
+    Library
+    -------
+    - Added const qualifier to source buffer parameters in H5Dgather and
+      H5D_scatter_func_t (H5Dscatter callback).  (NAF - 2013/7/09)
+
+    - CMake now creates *.so.{lt_version} files with the same version as 
+      configure.  (ADB  - 2013/06/05 HDFFV-8437)
+
+    Parallel Library
+    ----------------
+    - None
+
+    Performance
+    -------------
+    - None
+
+    Tools
+    -----
+    - h5dump: Added the option -N --any_path, which searches the file for 
+              paths that match the search path. HDFFV-7989 (ADB - 2013/08/12).
+    - h5dump: Added the optional arg 0 to -A, which excludes attributes 
+              from display. HDFFV-8134 (ADB - 2013/08/01).
+    - h5dump correctly exports subsetted data to a file, using the --output
+      option.  (ADB  - 2013/06/07 HDFFV-8447)
+    - h5cc and other compile scripts now default to linking shared libraries
+      when HDF5 is configured with the --disable-static option.  
+      (LRK - 2013-09-23 - HDFFV-8141)
+
+    F90 API
+    -------
+    - None
+
+    C++ API
+    ------
+    - None
+
+    High-Level APIs:
+    ------
+    - None
+
+    Fortran High-Level APIs:
+    ------
+    - None
+
+    Testing
+    -------
+    - test/big sometimes failed with the message of "file selection+offset not
+      within extent". This has been fixed. (AKC - 2013/09/28 HDFFV-8271).
+    - tools/h5diff/testh5diff.sh is run in every "make check", even after it
+      has passed in the previous run. It should not run again if there are no
+      code changes. Fixed. (AKC - 2013/07/19 HDFFV-8392)
+

+
+Known Problems
+==============
+* Several HDF5 command-line tools and tests leave behind generated files
+  that are not cleaned up with "make clean" or "make distclean" when software
+  is built in place. The issue will be addressed in the 1.8.13 release. We
+  recommend to use build directory to compile and test HDF5 as described
+  in the INSTALL file, section 4.2.
+ 
+* Source directory names with spaces in them will cause failures in configure
+  or make on Mac (HDFFV-8152), Linux, and probably all other platforms.  If a 
+  configure command with a space is run from a build directory, it will exit 
+  with an error message:  "checking whether build environment is sane... 
+  configure: error: unsafe srcdir value: '/scr/lrknox/hdf5 v1.8.12'".  If 
+  configure is run inside or below the directory with the space in the name, 
+  libtool will get the directory path from the system, put the part of the 
+  path before the space in the libdir variable in .../src/libhdf5.la, and 
+  then fail to find the nonexistent directory.  This is a known libtool issue 
+  and the suggested workaround is to rename the directory without spaces. 
+  (LRK - 2013/10/22)
+
+* CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv
+  catches some undefined behavior in the alignment algorithm of the macro 
+  DETECT_I in H5detect.c (HDFFV-8147). This issue will be addressed in the 
+  next release.  (SLU - 2013/10/16)
+
+* Running make check for the tools can fail in the tools tests if make was not
+  run prior. The tests for the tools use other tools in the tests, therefore
+  all the tools should be built before testing the tools. (ADB - 2013/10/09)
+
+* Make provided by Solaris fails in "make check". Solaris users should use
+  gmake to build and install HDF5 software. (AKC - 2013/10/08 - HDFFV-8534)
+
+* On OpenVMS, two soft conversion functions (H5T__conv_i_f and H5T__conv_f_i)
+  have bugs.  They convert data between floating-point numbers and integers.
+  But the library's default is hard conversion.  The user should avoid
+  explicitly enabling soft conversion between floating-point numbers and
+  integers. (Issue VMS-8; SLU - 2013/09/19)
+
+* On OpenVMS, ZLIB 1.2.8 library doesn't work properly.  ZLIB 1.2.5 works
+  fine.  So please use ZLIB 1.2.5 to build HDF5 library. (Issue VMS-5;
+  SLU 2013/09/19)  
+
+* When building using the Cray compilers on Cray machines, HDF5
+  configure mistakenly thinks the compiler is an intel compiler and
+  sets the -std=c99 flag which breaks configure on Cray. To build HDF5
+  properly on a Cray machine, please consult with the instructions in
+  INSTALL_parallel for building on Hopper.
+  (MSC - 2013/04/26 - HDFFV-8429)
+
+* The h5dump and h5diff utilities occasionally produce different output
+  between Linux and Windows systems. This is caused by lower-level library
+  routines that fail to write fill values to the user's buffer when reading
+  unallocated chunks from datasets that have a fill value set to
+  H5D_FILL_VALUE_DEFAULT. Due to platform differences the return of
+  spurious data values has only been encountered on Windows 32-bit systems.
+  (Issue HDFFV-8247; JP - 2013/03/27)
+
+* The 5.9 C++ compiler on Sun failed to compile a C++ test ttypes.cpp.  It 
+  complains with this message:
+      "/home/hdf5/src/H5Vprivate.h", line 130: Error: __func__ is not defined.
+  
+  The reason is that __func__ is a predefined identifier in C99 standard.  The
+  HDF5 C library uses it in H5private.h.  The test ttypes.cpp includes 
+  H5private.h (H5Tpkg.h<-H5Fprivate.h<-H5Vprivate.h<-H5private.h).  Sun's 5.9
+  C++ compiler doesn't support __func__, thus fails to compile the C++ test.
+  But Sun's 5.11 C++ compiler does.  To check whether your Sun C++ compiler 
+  knows this identifier, try to compile the following simple C++ program:
+      #include<stdio.h>
+
+      int main(void)
+      {
+          printf("%s\n", __func__);
+          return 0;
+      }
+  (SLU - 2012/11/5)
+
+* The C++ and FORTRAN bindings are not currently working on FreeBSD with the
+  native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the
+  ports (and probably gcc releases after that).
+  (QAK - 2012/10/19)
+
+* The following h5dump test case fails in BG/P machines (and potentially other
+  machines that use a command script to launch executables):
+
+   h5dump --no-compact-subset -d "AHFINDERDIRECT::ah_centroid_t[0] it=0 tl=0"
+     tno-subset.h5
+  
+  This is due to the embedded spaces in the dataset name being interpreted
+  by the command script launcher as meta-characters, thus passing three
+  arguments to h5dump's -d flag. The command passes if run by hand, just
+  not via the test script.
+  (AKC - 2012/05/03)
+
+* On hopper, the build failed when RUNSERIAL and RUNPARALLEL are set
+  to aprun -np X, because the H5lib_settings.c file was not generated
+  properly. Not setting those environment variables works, because
+  configure was able to automatically detect that it is a Cray system
+  and used the proper launch commands when necessary. 
+  (MSC - 2012/04/18)
+
+* The data conversion test dt_arith.c fails in "long double" to integer
+  conversion on Ubuntu 11.10 (3.0.0.13 kernel) with GCC 4.6.1 if the library
+  is built with optimization -O3 or -O2.  The older GCC (4.5) or newer kernel
+  (3.2.2 on Fedora) do not have the problem.  Users should lower the 
+  optimization level (-O1 or -O0) by defining CFLAGS in the command line of 
+  "configure" like:
+
+      CFLAGS=-O1 ./configure
+
+  This will overwrite the library's default optimization level.
+  (SLU - 2012/02/07 - HDFFV-7829)
+  This issue is no longer present on Ubuntu 12.10 (3.5.0 kernel) with 
+  gcc 4.7.2.
+
+* The STDIO VFD does not work on some architectures, possibly due to 32/64
+  bit or large file issues.  The basic STDIO VFD test is known to fail on
+  64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin
+  10.7.0.  The STDIO VFD test has been disabled while we investigate and
+  a fix should appear in a future release.
+  (DER - 2011/10/14 - HDFFV-8235)
+
+* h5diff can report inconsistent results when comparing datasets of enum type
+  that contain invalid values.  This is due to how enum types are handled in
+  the library and will be addressed in a future release.
+  (DER - 2011/10/14 - HDFFV-7527)
+
+* The links test can fail under the stdio VFD due to some issues with external
+  links.  This will be investigated and fixed in a future release.
+  (DER - 2011/10/14 - HDFFV-7768)
+
+* After the shared library support was fixed for some bugs, it was discovered
+  that "make prefix=XXX install" no longer works for shared libraries. It
+  still works correctly for static libraries. Therefore, if you want to
+  install the HDF5 shared libraries in a location such as /usr/local/hdf5,
+  you need to specify the location via the --prefix option during configure 
+  time. E.g, ./configure --prefix=/usr/local/hdf5 ...
+  (AKC - 2011/05/07 - HDFFV-7583)
+
+* The parallel test, t_shapesame, in testpar/, may run for a long time and may
+  be terminated by the alarm signal.  If that happens, one can increase the
+  alarm seconds (default is 1200 seconds = 20 minutes) by setting the
+  environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600
+  (60 minutes).  Note that the t_shapesame test may fail in some systems 
+  (see the "While working on the 1.8.6 release..." problem below).  If 
+  it does, it will waste more time if $HDF5_ALARM_SECONDS is set
+  to a larger value.
+  (AKC - 2011/05/07)
+
+* The C++ and FORTRAN bindings are not currently working on FreeBSD.
+  (QAK - 2011/04/26)
+
+* Shared Fortran libraries are not quite working on AIX. While they are
+  generated when --enable-shared is specified, the fortran and hl/fortran
+  tests fail. We are looking into the issue. HL and C++ shared libraries
+  should now be working as intended, however.
+  (MAM - 2011/04/20)
+
+* The --with-mpe configure option does not work with Mpich2.
+  (AKC - 2011/03/10)
+
+* While working on the 1.8.6 release of HDF5, a bug was discovered that can
+  occur when reading from a dataset in parallel shortly after it has been
+  written to collectively. The issue was exposed by a new test in the parallel
+  HDF5 test suite, but had existed before that. We believe the problem lies with
+  certain MPI implementations and/or file systems.
+
+  We have provided a pure MPI test program, as well as a standalone HDF5
+  program, that can be used to determine if this is an issue on your system.
+  They should be run across multiple nodes with a varying number of processes.
+  These programs can be found at:
+  http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/
+  (NAF - 2011/01/19)
+
+* All the VFL drivers aren't backward compatible.  In H5FDpublic.h, the
+  structure H5FD_class_t changed in 1.8.  There is new parameter added to
+  get_eoa and set_eoa callback functions.  A new callback function
+  get_type_map was added in.  The public function H5FDrealloc was taken
+  out in 1.8.  The problem only happens when users define their own driver
+  for 1.6 and try to plug in 1.8 library.  Because there's only one user 
+  complaining about it, we (Elena, Quincey, and I) decided to leave it as 
+  it is (see bug report #1279).  Quincey will make a plan for 1.10.
+  (SLU - 2010/02/02)
+
+* The --enable-static-exec configure flag will only statically link libraries
+  if the static version of that library is present. If only the shared version
+  of a library exists (i.e., most system libraries on Solaris, AIX, and Mac,
+  for example, only have shared versions), the flag should still result in a 
+  successful compilation, but note that the installed executables will not be 
+  fully static. Thus, the only guarantee on these systems is that the 
+  executable is statically linked with just the HDF5 library.
+  (MAM - 2009/11/04)
+  
+* Parallel tests failed with 16 processes with data inconsistency at testphdf5
+  / dataset_readAll. Parallel tests also failed with 32 and 64 processes with
+  collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks
+  with MPI IO.
+  (CMC - 2009/04/28)
+
+* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers, 
+  use -mp -O1 compilation flags to build the libraries. A higher level of 
+  optimization causes failures in several HDF5 library tests. 
+
+* A dataset created or rewritten with a v1.6.3 library or after cannot be read 
+  with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
+  There was a bug in the calculation of the Fletcher32 checksum in the 
+  library before v1.6.3; the checksum value was not consistent between big-
+  endian and little-endian systems.  This bug was fixed in Release 1.6.3.  
+  However, after fixing the bug, the checksum value was no longer the same as 
+  before on little-endian system.  Library releases after 1.6.4 can still read 
+  datasets created or rewritten with an HDF5 library of v1.6.2 or before.
