What is the story regarding backwards compatibility when upgrading from Linux
32 bit Performer 3.1.1 to Performer 3.2?

Under IRIX, it seems that previous versions of the various Performer .so files
were included and thus old user application binaries would continue to work.

We have just upgraded a Linux 32 bit Laptop from 3.1.1 to 3.2. The first
attempt at installing 3.2 without removing 3.1.1 produced installation
conflicts. We then removed the 3.1.1 installation and installed 3.2. But now
we can not run our performer binaries that were compiled under 3.1.1.

One answer is of course to re-compile our applications which we will do in
time. However, we have several Linux machines and we distribute
application binaries and it will be very difficult to upgrade all machines
to 3.2 at the same time.

I am hoping there is a solution that will let us run 3.1.1 binaries under 3.2.
I would be happy with supporting just one previous release.

Is there a solution to my compatibility problem?

Thanks,
Steve
