HDF5 for Debian
===============
On thread safety
----------------
Some general notes for developers: since 1.8 series HDF Group deprecates
enabling the thread-safe option for the C library and at the same time
supporting high level (HL), C++ and Fortran bindings. Those options cannot
cohexist for safety because non C libraries wrapper are not thread-aware.
Debian GNU/Linux still support a C thread-safe library and the alternative
bindings, but it does not imply that the Debian distributed high level, C++
aand Fortranalibraries are thread-safe.
For short: DO NOT use HL, C++ or Fortran bindings in multi-thread programs
witihout providing yourself mutex infrastructure support for every wrapped
function. You can use safely only the C binding in a multi-thread environment.
That was not different in 1.6 series, just the issue was ignored.
Now, you are warned.

1.10.0 and 1.10.1 compatibility
-------------------------------
From HDF Group newsletter #153:
HDF5 releases are always backward compatible. In general, they are also
forward compatible in maintenance releases of a major release. However,
the HDF5 - 1.10.0 maintenance release will NOT be able to read HDF5 - 1.10.1
files that contain a metadata cache image. The metadata cache image must be
removed with the h5clear tool in order for HDF5 - 1.10.0 to read the file.
