Adobe Flash Player Projector 22.214.171.124 is the current (as of March 18, 2015) stable release of the standalone player. It contains security updates which patch vulnerabilities from previous versions, and additional features.
What does not
What was not tested
Like in Windows, if your Flash app being run needs to reach out to the internet for any reason you will need to change the security settings inside of the Flash player (the "Global Settings" window - this looks like it no longer functions inside of Wine, but I have to go digging to debug it). Silver rating because Internet-reaching applications may have problems, and application datadirs outside of the working directory where a .swf exists may not function correctly.
