I saw today that FireFox released a new version (5). I tried reading about what was added and ran into this link: http://arstechnica.com/open-source/news/2011/06/firefox-5-released-arrives-only-three-months-after-firefox-4.ars
It states that:
Mozilla has launched Firefox 5, a new version of the popular open source Web browser. This is the first update that Mozilla has issued since adopting a new release management strategy that has drastically shortened the Firefox development cycle.
I find this very intriguing - any idea what this new strategy is?
