0.5.2 (August 3, 2010)

vagrant up can be used as a way to resume the VM as well (same as vagrant resume). [GH-134]
Sudo uses "-E" flag to preserve environment for chef provisioners. This fixes issues with CentOS. [GH-133]
Added "IdentitiesOnly yes" to options when vagrant ssh is run to avoid "Too Many Authentication Failures" error. [GH-131]
Fix regression with package not working. [GH-132]
Added ability to specify box url in init, which populates the Vagrantfile with the proper config.vm.box_url.

0.5.1 (July 31, 2010)

Allow specifying cookbook paths which exist only on the VM in config.chef.cookbooks_path. This is used for specifying cookbook paths when config.chef.recipe_url is used. [GH-130] See updated chef solo documentation for more information on this.
No longer show "Disabling host only networks..." if no host only networks are destroyed. Quiets destroy, halt, etc output a bit.
Updated getting started guide to be more up to date and generic. [GH-125]
Fixed error with doing a vagrant up when no Vagrantfile existed. [GH-128]
Fixed NFS erroring when NFS wasn't even enabled if /etc/exports doesn't exist. [GH-126]
Fixed vagrant resume to properly resume a suspended VM. [GH-122]
Fixed halt, destroy, reload to where they failed if the VM was in a saved state. [GH-123]
Added config.chef.recipe_url which allows you to specify a URL to a gzipped tar file for chef solo to download cookbooks. See the chef-solo docs for more information. [GH-121]
Added vagrant box repackage which repackages boxes which have been added. This is useful in case you want to redistribute a base box you have but may have lost the actual "box" file. [GH-120]
