When installing a new plugin does not write the version?

Question

Web development

I wrote a plugin .
In the Developers section, it is spelled correctly - Current Version 0.5.
And in the sitebar in the Current Version there is a pass, as well as in the search when adding a plugin. Because of what the plugin update on the site does not work.
Readme.txt says "Stable tag: 0.5".

Where is the mistake and how to fix it?
