• The Virtual File Layer, VFL, was added to replace the old file drivers. It also provides an API for user defined file drivers.

• It includes Fortran 90 support for Solaris 2.6 and 2.7, Linux, DEC Unix, Cray T3E, Cray J90 and SGI Origin 2000.

• It includes the h4toh5 tool for converting HDF (4) files into HDF5. This was tested on Solaris 2.5 and 2.6, IRIX 6.5, HP-UX 11.0, DEC Unix, FreeBSD, and Windows 2000.

• It includes C++ support for Solaris 2.6 and 2.7, Linux, and FreeBSD.

Changes in this Release

• All bugs in our database were fixed.

• The Java HDF Interface (JHI) was upgraded and built with the HDF 4.1r4 library. This bug fix release of the library fixes several serious problems with JPEG images, which affected the viewer.

• External files are supported. The JHV now uses the environment variable HDFEXTDIR by default, and the user may set the external file path using the preferences dialog.
