You should follow this Opera development blog: Opera Desktop Team - Desktop Team
Opera is kind of doomed browser because of web developers not adding compatibility for it. Personally also like Opera but its site incompatibility makes me very sad.
Go with kutkutariyaan link, its latest Opera with new Presto engine. Opera 12.50 is going amazing in development.
Also if you have 64-bit OS, I prefer you to install 64-bit Opera (even little slower) but better since it uses Processor instruction sets more efficiently.
