v0.1.21 - maintenance

News:

passing a promise to an m.prop now populates it with the resolved value upon resolution, and returns undefined otherwise
m.redraw can now be forced to called synchronously

prevent routes from reverting to original route in some cases
fixed nested array ordering #156

v0.1.18 - maintenance

Bug Fixes:

routing now correctly clears diff cache #148
fixed incorrect context unloading when reattaching a child to a new parent

v0.1.17 - maintenance

News:

config contexts can now have an onunload property for clean up tasks after elements are detached from the document
route changes now re-render from scratch, rather than attempting a virtual dom diff
virtual elements that are children of an array can now accept a key attribute which maintains the identity of the underlying DOM elements when the array gets shuffled #98

in m.request, non-idempotent methods now automatically send appropriate Content-Type header if serialize is JSON.stringify #139

v0.1.16 - maintenance

Breaking changes:

changed default value for xhr.withCredentials from true to false for m.request, since public APIs are more common than auth-walled ones. #14

In order to configure this flag, the following configuration should be used:
```
var privateAPI = function(xhr) {xhr.withCredentials = true};

m.request({method: "GET", url: "http://foo.com/api", config: privateAPI});
```
