* https://github.com/capistrano/bundler/issues/45#issuecomment-69349237

* Bugfix:
* release_roles did not honour additional property filtering (@townsen)
* Refactored and simplified property filtering code (@townsen)

* Breaking Changes
* Hosts with the same name are now consolidated into one irrespective of the
user and port. This allows multiple declarations of a server to be made safely.
The last declared properties will win. See capistrnorb.com Properties documentation
for details.
* Inside the on() block the host variable is now a copy of the host, so changes can be
made within the block (such as dynamically overriding the user) that will not persist.
This is very convenient for switching the SSH user temporarily to 'root' for example.

* Minor changes
* Add role_properties() method (see capistrano.github.io PR for doc) (@townsen)
* Add equality syntax ( eg. port: 1234) for property filtering (@townsen)
* Add documentation regarding property filtering (@townsen)
* Clarify wording and recommendation in stage template. (@Kriechi)
* Both available syntaxes provide similar functionality, do not use both for the same server+role combination.
