888LM failed, capacitor seems to be leaking

I have an 888LM which was connected to an 8500 liftmaster opener.  My garage door opened in the middle of the night, and in the morning the 8500 started flashing 3 blinks (opener short).  I've read of many people having this reliability problem.  When I opened up the controller I can see fluid has leaked from one of the capacitors.  This seems to be a widespread problem with these openers and a security issue as well.  Has this been fixed in more recent 888LM models?  Is Chamberlain standing behind these products and replacing them?
