Hello everyone,

A pre-release candidate version of HDF5 1.8.15 is available for testing
and can be downloaded at the following link:

http://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.15-pre3/

This is a maintenance release that has many bug fixes, (hopefully!)
reduced  number of compiler warnings and updated autotools. CMake fans
will need CMake 3.1 to build HDF5-1.8.15. For more information see
RELEASE.txt
<https://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.15-pre3/hdf5-1.8.15-pre3-RELEASE.txt>

Hi Elena,
two points:

1) For a Maintenance only why a ABI bump ?
   HDF5 is the only package, I am aware of, that in averages
   bump the ABI    every 2 releases. This time two bumps in the row.

There were changes in the C public headers and symbols were added/removed for 
C++.

All,

Please see compatibility 
report<https://www.hdfgroup.uiuc.edu/ftp/pub/outgoing/hdf5/hdf5-1.8.15-pre3/hdf5_v1814_v1815snap14_interface_compatibility.html>
 that was created at code freeze for HDF5 1.8.15.


2) I wasted some time to discover this change

## Disable shared libraries on CYGWIN. (LK - 04/16/15)
## A number of tests run by "make check" fail on CYGWIN, so for HDF5 v1.8.15
## we will change the default for shared libraries to disabled.
...

This seems, in my humble opinion, a questionable approach.

I am running tests with shared libraries re-enabled and
I will look on these new failures.

dt_arith test fails with the shared libraries. If you need to build shared, you 
should be able to use the —enable-shared configure option.

Thank you!

Elena
