People's main gripe has been that the dependencies and the bundling solution that was available with Merb 1.0 has been quite painful. Fixing all this has been the focus of this past week, and with the Merb 1.0.5 release comes a new solution. Watch the screencast demonstrating all those new features.
I have been noticing an increase of blog posts regarding Merb ever since it hit 1.0. Most of them are positive, some mention a number of gripes. I thought I would voice my opinion about the issues come up the most, such as ORM agnosticism and the Merb dependencies situation.
