The upcoming platform update is scheduled for Wednesday, March 5 2014.
Ruby 2.1.1 is added to the stack. Rubies 2.0.0 and 1.9.3 get upgraded patchlevels, so bundle update debugger will likely be necessary.
Firefox goes up to version 27, requiring bundle update selenium-webdriver for most projects that use that gem.
Node and NPM are updated to the latest versions too.
A full list of changes is available in the platform changelog.
Update March 6: ElasticSearch package changed and it no longer runs the server on boot. Users will need to add sudo service elasticsearch start as their first build setup command. Sorry about that, we’ll have it fixed shortly.
Update March 17: ElasticSearch server now runs on boot again.
