This morning I started getting the following warning when running tests.
DEPRECATION WARNING: <% %> style block helpers are deprecated. Please use <%= %>.
I can see how to fix the warning.
How is it possible to start to get a warning without changing any code or updating any gems?
Working in Rails 3, Ruby 1.92.
According to section 7.4.2 of the Rails 3.0 release notes,
<%=is the standard for helpers that insert content. So, you must’ve had the deprecation warning when using a Rails 3 application according to the documentation, but perhaps you never noticed it.
