Bene... un altro download del mio programma 
preferito!!!
You can get it from our download page. Or, if you already have a previous version of 2.5 installed, just go to File -> Updates -> Check Now. Note that the help/documentation is still incomplete -- the RC status is for the code, and we're still working on the docs. We are well on track for our November 30th final release. Fixes for this release:
Increased updater's compatibility with various proxies, especially those requiring authentication 
Fixed Auto-Levels incorrect white-balance computation 
Fixed the Save As dialog not showing filenames 
Fixed the updater not offering stable releases if the user opts-in to beta notification 
Fixed data corruption bug with interaction between the two Move tools and undo 
Fixed many various input, localization, and crash bugs 
Help documentation is more complete, but NOT finished (RC status is for the code) 
As always, feel free to post feedback and bug reports at our forum. Thanks!
