Rails - how do I confirm the version of a plugin

I noticed that a rails plug-in I am using has had several fixes made to it, and im a little worried about all the o开发者_高级运维ther rails apps i have written.

Ideally I would like to have a script that can compare the checked out version of the plug-in against the repo version. Does anyone know if rails stores this info anywhere or if there is a patch/gem to add this capability to rails?

Thanks

Generally the readme file of the plugin can contain the version . However this is the difference between a plugin and a gem . Gems tend to have proper versions , with plugin there is no such criteria .
Also , I am not sure if you want to be upgrading to the latest plugin always as plugins are not always backward compatible and you run the risk of breaking your app .
