Why? If a system runs 0.10, it can also run 0.11. I didn't even understand why was 0.10.3 released when we had 0.11 since July. Devs need to focus on updating the most recent version...
Agree, there is a logic reason about new release version, people should focused to upgrade their version as soon as possible, dunno why people dont do it, well, i can accept it when old system are used and cant run latest version, but im not sure that this is the case with bitcoin core.
Btw if they have a test version on his web, probably they will release it soon.
