The biggest changes have been previously described, many minor bugfixes, large file downloading and uploading.

• Download: gem install camping
  (Updates ActiveRecord to >=1.14.0, Markaby to >= 0.4)
• Docs: camping.rubyforge.org
• Wiki: code.whytheluckystiff.net/camping

But that’s all kind of overkill when it’s just:
