We pleased to announce the release of Chandler 0.4! The high-level goal of the 0.4 release is to be "experimentally usable" for a few key end-user tasks.

In 0.4, you can:
-- Create, edit, and view PIM Items: Email, Calendar Events, Task, and Notes.
-- Add or change the Task, Email, or Event properties of any PIM item, in a process we call "stamping".
-- Share collections of items (including calendars) via a WebDAV server.
-- Perform very basic email and calendar operations (e.g. sending and receiving email, or creating and modifying calendar events).

In addition, the 0.4 Release provides:
-- Sending and receiving of mail over a TLS/SSL connection (a fully secure TLS transport is not implemented yet)
-- A basic UI landscape: Sidebar, Tabs, Summary & Detail views

You can download the release for Linux, MacOS, and Windows, at:
http://downloads.osafoundation.org/chandler/releases/0.4/

For more information you can see the Chandler 0.4 Read Me document.

There is also a Guided Tour document that walks you through some of the new features in 0.4 like stamping and sharing.

Enjoy!
