Octopress capitalization in new messages

I updated my Octopress blog today and when I ran:

rake new_post["This is a test of title"]

      

        
        
        
      

    

It creates my markdown file at source /_post/2013-02-18-this-a-test-of-title.markdown, then I run:

rake generate

      

        
        
        
      

    

and

rake preview

      

        
        
        
      

    

And the message now has a title

This Is A Test Of Title

      

        
        
        
      

    

I go through the markdown source and find that

...
title: "This is a test of title"
...

      

        
        
        
      

    

So the markdown is fine. Also on the web page I am using Chrome developer tools to see if the css property has a "capizeize" value, but it doesn't, the anchor looks like this:

<a href="...">This Is A Test of Title</a>

      

        
        
        
      

    

This is how the problem of caching cames from the framework looks like.

In the imathis / octopress repostory wiki https://github.com/imathis/octopress/issues/202 it seems that some people who post in other languages ​​don't like this "feature" and even in Rakefile, imathis removed this line:

post.puts "title: \"#{title.gsub(/&/,'&').titlecase}\""

      

        
        
        
      

    

for this:

post.puts "title: \"#{title.gsub(/&/,'&')}\""

      

        
        
        
      

    

for this commit, so I open my Rakefile and have the last line, so my file is updated, but obviously the problem persists

Any idea how to avoid this behavior in post headers?
