- App Engine Rack updated to version 0.0.7 and now includes
deferred dispatcher and depends on JRuby-Rack 0.9.7 gem
- App Engine SDK updated to version 1.3.2
- App Engine APIs updated to version 0.0.14
- DM Adapter updated to version 0.0.8
Reliable Spin-up - Our biggest show-stopper has been apps not consistently initializing within 30 seconds. Thankfully, @urekat came up with a simple solution to mitigate this problem, using redirects to break-up loading requests. We've packaged the deferred dispatcher with appengine-rack for your convenience.
JRuby Updates - A new version of Warbler was just release, we hope to take advantage of some of the new features for our Rails 3 setup process. We also expect to see a release candidate of JRuby 1.5 any day now, and jruby-openssl 0.6.1 should follow.
OAuth & OpenID - Thanks to some hard work from @ribrdb and @nahi, the jruby-openssl 0.6.1 gem will work properly on App Engine. The lack of a released gem has not stopped some developers from forging ahead. You should wait for jruby-openssl 0.6.1, but here are a couple examples from @azazeal and @baroquebobcat that use an altered gem to support OAuth and OpenID.
Nokogiri Java Port - As @headius has recently reported, the pure-Java version is very close to 100% passing. Thanks to an epic effort from Sergio Arbeo,
Success Stories - A recent tweet from @app engine links to a blog post about Starting your business in less than a week with Rails on App Engine. The app runs Rails 2.3.5 with DataMapper on App Engine. The timing was just right when @azazeal started building his app, and he was determined to push through any issues. We also have a lot of utility apps like jruby-ci, so if you've been on the fence, consider using App Engine for your next Ruby app.
