Hi Philippe and others!
While I am waiting for pre-8-update process to finish, here're some words about the process itself:
Unfortunately it did not go very well. First, based on my earlier problems with mac, I started the update in PC (win7). At quite early stage there was some error message and suggestion to start again. Same time I noticed that Origin Connection did got stucked and I had to use Windows task manager to shut it down. Then, when I tried same again, update did not even start and Connection went down before beginning the process. Then I choosed to try this update in Mac. Unfortunately "same old" problems were there: Origin connection looses to the connection after the boot request and crashes the app (I have had this problem since first 1.4 pre). Now, I restarted the PC/windows and tried once more and update went fine after all.
...more report coming soon...
