+Release 2.5.1 Web Player auto-update Tech Note
+
+    During testing of 2.5.1 we have identified and fixed an issue that affects auto-update behaviour of the web player plugin. This tech note explains the issue and the steps that are required to be taken by customers publishing content using Unity 2.5.1 or later.
+
+    The Unity Web Player has a mechanism that automatically updates when it encounters content that requires a newer version of the Unity Web Player. In that case Unity downloads and installs an update to the Unity Web Player completely automatically. Under Windows Vista, when UAC (User Account Control) mode is enabled and Internet Explorer is used as the browser, we have discovered a situation where this auto-update will fail.
+
+    Under Windows Vista only, when the browser is Internet Explorer, if the 2.5.0 Unity Web Player was installed and Vista's UAC is on, it is impossible for the plugin to be automatically upgraded to 2.5.1. However, a manual install will successfully upgrade the 2.5.0 plugin to 2.5.1.
+
+    This issue only happens when upgrading from 2.5.0 to a later plugin. Earlier versions of the plugin (2.1.0, 2.0.2 etc.) do not have this problem. The problem itself is wrong manifest information in web player update application, which makes it not have enough permissions to perform the update on Vista + UAC + Internet Explorer.
+
+    To help customers we have changed the default HTML template built by Unity when building web content. The change is in a VBScript snippet we recommend be used on the containing web page to identify which version of the plugin is installed. We have updated the "Detecting the Unity Web Player using browser scripting" page of the Unity Manual. We urge all customers to visit this page, understand the significance of the change and update their HTML pages accordingly. The change recommended is that if the script detects Windows Vista and Internet Explorer and Web Player Plugin version 2.5.0 the page should pretend that the plugin is not installed. The gamer should be recommended to download and install the plugin manually. The Support team at Unity is aware of the issue and can help customers who require assistance with this change.

+Upgrade Guide
+
+    Unity 2.5 projects are compatible with Unity 2.1, so if you do not use new 2.5 features, you can open your projects with Unity 2.1.
+
+    Timeline window for creating animations directly in Unity was removed in 2.5. Of course you can still author animations in a 3D application. This feature will return even better in Unity 2.6 including High-end Curve Editing and support for animating any property including material animation.
+
+    Some of the Editor scripting API was refactored, here are the largest changes:
+
+    EditorWindow.OnCloseWindow is removed. Use OnDestroy instead.
+    
+    Hotkey part in MenuItem name requires a space character before the hotkey now.
+    
+    Removed Mac Ctrl (^) modifier support from MenuItem hotkey.
