+
+### General
+
+- Added new `docker-machine mount` command for mounting machine directories over SSHFS
+- Improved some logging messages
+- Fixed a bug with the `scp` command when using an identity file.
+- Fixed a parsing error that caused the boot2docker ISO cache to malfunction, forcing a new download everytime.

+### Drivers

+- `exoscale`
+  - Updated driver
+  - Removed default `docker-machine` affinity group if no other affinity group was specified
+- `virtualbox`
