Right now it looks a bit empty, but I'm sure it will fill up soon.
You can add your game by creating a thread in the Games Forum. If you already have a thread for your game, you will find a "Edit Game Info" link at the top of your thread, where you can upload a screenshot and set the URL.
Impact 1.22 fixes a number of issues with Internet Explorer on Windows8/RT and Windows Phone. Font loading should now be more robust in recent Ejecta versions as well.
As always, if you're updating from a previous version, take care to not overwrite your own files. You'll just need to update the files in lib/impact/ and lib/weltmeister/. Grab the new version from your download page.

Apple recently released a new version of their Safari Browser for Retina MacBooks that breaks many Impact games and produces garbled fonts and blurry scaled up versions of games. I wrote a bit more about this whole ordeal over at PhobosLab.
Impact 1.21 carefully works around these issues. If you want your games to run on Retina MacBooks in Safari, you should update.

The Ejecta github project is still full steam ahead. This 1.2 release again brings a whole bunch of bugfixes, moves the Canvas implementation closer to the spec and adds some missing features. Notably, this release brings support for ctx.clip() for the Canvas element. The only missing Canvas features are now gradients, shadows and patterns.
Thanks again to everyone who contributed and reported bugs!

We're looking into bringing this over to Ejecta proper for some future release.
The Ejecta github project has been very busy in the last few weeks. We fixed a whole bunch of issues, made the project much more stable and added a good deal of new features.
A huge thanks goes to Tharit who fixed a lot of issues with vector functions and implemented the excellent and fast font rendering routines. Also thanks to anyone else who contributed to the project and reported bugs.

Ejecta has been formerly known as iOSImpact. It still shares the same idea and some basic code with iOSImpact, but is otherwise a significant rewrite of it.
The whole Canvas implementation has been re-implemented from scratch and is now much faster, more robust and closer to the HTML5 spec. It also supports the vector drawing functions, such as lineTo(), bezierCurveTo(), fill() and stroke() as well as getImageData() and many others.
iOSImpact used a lot of Impact specific hacks and you needed a special set of plugins to make Impact work with it. This is no longer the case – Impact games now work without any modifications or plugins in Ejecta.
Ejecta has become much more generally usable. It's not only a tool to get Impact games running on iOS, but can also be used for many other Canvas animations and games.
Because Ejecta is no longer focused on Impact only, I decided to release it as Open Source to see what the community comes up with. I'm also hoping that the community will help out to fill the last gaps in the Canvas implementation and also provide some more functionality such as in-app purchases or WebSocket support.
Visit the Ejecta page for more info. If you're upgrading from iOSImpact, be sure to read the Integrating Impact Games article.
I also wrote a bit about some implementation details in my blog.
