A number of small installation problems and/or bugs which appeared in the DEC96 release have been fixed in the APR97 release. The APR97 release also incorporates two internal changes: the merging of two libraries (libgag.a and library.a), and the ``disparition'' of the ``old'' CLASS program. The new CLASS program incorporates full support for the On-The-Fly mapping.
The APR97 release is complete for HPUX, AIX and Dec-OSF1 systems. The SIC Window facilities are still not available for SunOS, Solaris, Ultrix and Linux.
Finally, since PCs are now extremely widespread and powerful enough to handle the type of data processing required by the IRAM instruments, we have undertaken a porting of the GILDAS software to the Windows-95 operating system.
