-## 0.1.2 (unreleased)
+## 0.1.3 (July 1, 2013)
+
+FEATURES:
+
+* The VMware builder can now upload the VMware tools for you into
+  the VM. This is opt-in, you must specify the `tools_upload_flavor`
+  option. See the website for more documentation.
+
+IMPROVEMENTS:
+
+* digitalocean: Errors contain human-friendly error messages. [GH-85]
+
+BUG FIXES:
+
+* core: More plugin server fixes that avoid hangs on OS X 10.7 [GH-87]
+* vagrant: AWS boxes will keep the AMI artifact around [GH-55]
+* virtualbox: More robust version parsing for uploading guest additions. [GH-69]
+* virtualbox: Output dir and VM name defaults depend on build name,
+  avoiding collisions. [GH-91]
+* vmware: Output dir and VM name defaults depend on build name,
+  avoiding collisions. [GH-91]
+
+## 0.1.2 (June 29, 2013)

+The result signature of this method is `(Artifact, bool, error)`. Each

+
+* `Artifact` - The newly created artifact if no errors occurred.
+* `bool` - If true, the input artifact will forcefully be kept. By default,
