Hi Matevz,
Uhhhh, no not on this thread – it has nothing to do with pfc. But now that yiou bring it up, you should still try to be backward compatible in the config file. It may mean ignoring a directive but certainly changes should not cause the server to abort.

About pfc configuration ... there is a new mandatory configuration directive pfc.ram so accepting old pfc configuration syntax will not help.
I assume we are talking about pfc.prefetch that now requires an argument? Pfc can now prefetch data blocks in a more efficient manner so, if prefetching is used, it makes a lot of sense to set it to some value other than 1 (which would be the default).
