Are there any plans to update this to use Capistrano 3.x?
Are there any current plans to bring this up to date? It seems the current deploy scripts don't work with a fresh install of Capistrano. I found a number of articles attempting to address this and similar issues, but they seemed old and not applicable to the current releases. My Ruby knowledge is non-existent, so I wasn't able to apply the old solutions to the current problems.
If you want the current version to work you can install capistrano v2.15.5 :
sudo gem install capistrano -v 2.15.5
sudo gem install capistrano-ext railsless-deploy
If you want to use Capistrano 3, there is this repo : https://github.com/Mixd/wp-deploy. I haven't tried it but it seems to provide a similar logic.
