Node 0.10.12 was released yesterday. This version updates v8 and npm, and has a fix for the net module.
One minor change that I liked was readline now supports
CTRL-L for clearing the screen -- that means Node's command-line interface will do this as well. Before hitting
CTRL-L did nothing, which wasn't very intuitive if you're used to using readline tools.
If size is important to you, then you'll like grunt-micro (GitHub: markdalgleish / grunt-micro, License: MIT, npm: grunt-micro) by Mark Dalgleish. This Grunt plugin ensures a script is smaller than a given size. Mark suggests this is useful for client-side authors that have size claims in their project documentation, but it could be useful for other things, like warning about asset sizes in mobile projects.
connect-prerenderer (GitHub: dai-shi / connect-prerenderer, License: BSD, npm: connect-prerenderer) by Daishi Kato is middleware for pre-rendering content to support systems that don't interact well with Ajax-heavy interfaces. This is ideal for improving the SEO of a site.
The author has paid special attention to AngularJS -- the documentation includes some Angular client-side code that adds support for the module.
