0.4.0 (???)

Breaking change: the result object returned by the fetch function of the URL Fetch service no longer converts header names to keywords.
Made it possible to store datastore entities in memcache during interactive REPL development.
Added a hack to allow uploads to the Blobstore service from an application, without involving a web browser.
Modified the Datastore service to optionally support storing values of arbitrary readbly-printable Clojure types.
Added the Images service.
Breaking change: removed appengine-magic.services.url-fetch/fetch-async function and replaced its functionality with a new :async? keyword to appengine-magic.services.url-fetch/fetch.
Added the Channel service.
Made swank.core/break work inside Ring handlers (using middleware included from Ring).
Added the ability to directly execute App Engine API calls from the REPL.
Enabled the use of the administrative console (/_ah/admin), including the datastore viewer, from the interactive REPL environment (thanks to Yuri Niyazov).
Added two new Leiningen tasks: appengine-update and appengine-dev-appserver. They allow maintaining multiple App Engine production environments with different versions (e.g., production and staging).
Added support for Google App Engine SDK 1.3.8 through a custom Maven repository.

0.3.1 (2010-11-30)

Added as-* type conversion functions to the Datastore service.
Breaking change: appengine-magic.services.blobstore/uploaded-blobs now takes a Ring request map parameter (instead of an HttpServletRequest). This is for consistency with the rest of the services API.
Added a version of multipart-params middleware which works in App Engine (thanks to Conrad Barski).

Added appengine-magic.core/appengine-environment-type.
Deprecated including the :aot directive in project.clj files.
Added exists? function to the Datastore service.
Added the Task Queues service.
Added the Mail service.
Added the Blobstore service.
Speeded up production deployment by packaging compiled application .class files into a .jar. Eliminated the WEB-INF/classes/ directory.
Added support for general classpath resources with the appengine-magic.core/open-resource-stream function.
Breaking change: moved the web application from resources/war/ to resources/. This provides better support for using general classpath resources.
Breaking change: renamed all destructive Memcache service operations to have a trailing ! character; e.g., appengine-magic.services/put became appengine-magic.services/put!.
