Intellij Ruby plugin versus RubyMine

Here is described difference between RubyMine and Ruby plugin: https://devnet.jetbrains.com/docs/DOC-1146

Thanks Andrey.

As this question was answered a long time ago, I'd like to ask if the answer is still true and if yes, how big is the average time difference until features of RubyMine are transferred into the plugin? Is it more like a couple of weeks or half a year? Thanks.

Now the time shift is not more than one week.

Thanks Andrey.
