Nessus Sessions and Plugin Updates

[Jack Mogren <mogren () mayo edu>]

  Can someone fill me in on how Nessus plugin updates affect sessions created in the NessusWX client?  I have created 
several sessions in NessusWX.  I have configured each session's plugins differently, disabling whole familys of 
plugins, etc.  I perform a plugin update on my Nessus server nightly.  When I first connect to my server it downloads 
all the plugins, including the new ones.  What affect does this have on my sessions?  Are the plugin familys updated 
too?  Are the new individual plugins enabled within each family?  Or is it up to me to recconfigure my sessions every 
time?
