But one way this could affect you (as I mentioned in the April blog post) would be if you have developed an application that connects via SSL to a web server that is also processing credit card payments. When that server is updated to SSLv3, your app may need to be updated as well. See my April post for more details on that.
One such application is any version of REAL Studio/REALbasic prior to 2010 release 2. We will be updating our web server to SSLv3 soon (we are required to by July 1st) and when we do, these older releases will no longer be able to connect to our server to verify your license key should you need to re-install it. But never fear. We have a solution. Should you need to reinstall your license key for REAL Studio/REALbasic 2010 r1 or earlier, please contact customer service and they will provide you with instructions. It's a very quick process. And we will reply back to your requests promptly.
I apologize in advance for the inconvenience. We, like all other companies that accept payment via credit card, are required to do this. REAL Studio 2010 Release 2 is already set up to handle SSLv3 so once you are up to date to this version or later, you will no longer have to deal with this problem.
