Ruby on Rails, the open source web application framework written in Ruby that strives for simplicity, launched Rails 1.1 recently (March 27, 2006). The launch updated Rails with 500 fixes, tweaks, and features from more
than 100 contributors. These Rails 1.1 tweaks are meant to make Rails operate more smoothly.
Ruby on Rails seems to be gaining traction in development circles for its easy of use as a solid tool-set. Carlos Pero had this to say about Rails in general:
"I've been developing dynamic Web sites for over 12 years, and it's nice to see evolution in the tools used."
I have not yet developed anything using Rails specifically so it is difficult for me to weigh in on it. I'll have to wait until I get additional Rails tinkering under my belt.
