Is there any problem with versions compatibility?
A project I started with 1.1.2 cannot run with 1.1.4.
Dreamhost recently updated their rails from 1.1.2 to 1.1.5 and 1.1.6.
Needless to say I got “Application Error”. However when I changed
RAILS_GEM_VERSION to either 1.1.5 or 1.1.6, it works. (Haven’t made a
thorough checking though.)
Here it seems there is no compatibility problem between 1.1.2 and 1.1.5
So if, I started with one version (e.g. 1.1.2) will it still work after
rails upgrade later (e.g. 1.9.9)?
What is the significance of RAILS_GEM_VERSION? Will changing it to other
versions break my application?
Is there any way to automatically set RAILS_GEM_VERSION to latest
installed Rails version (i.e. without editing environment.rb)?
