Using a template for distribution evaluation, I have installed and tested FC5-test2. Unfortunately since I did not install FC5-test1 due to installer limitations, I cannot compare this with test1. However, from what I’ve seen so far it seems much better than the poorly created FC4. Installer I chose to install using the install from ISO images on disk option (available via the linux askmethod boot option). I burned CD1 to a CD-RW and booted.
The most current version of Flash for Linux is version 7.0 while Windows users are already on 8.0. However Macromedia has officially stated that there will be an upcoming version 8.5 for Linux. However it will be shipped after the Windows version becomes available. Even though that post states that no 64bit version is being planned, another engineer has stated that there is some work being done towards a 64bit version.
