What's new in Composite C1 4.1
The following are highlights of major changes since Composite C1 4.0:

General user features:

• Drag-and-drop images and files like PDF and Word documents directly from your own desktop and folders into page content
• Allow you to install Composite Form Builder - an effective, extensive and easy to use tool for building web forms
• "Open Cph" Starter Site upgraded to Bootstrap 3 - powerful mobile first front-end framework.
• Seamless switch between content languages for users working with content in more than one language
• Internet Explorer 11 support
• Microsoft .NET 4.5 required - yielding across-the-board performance improvements and new developer features
• Latest versions of TinyMCE (Visual Editor) and CodeMirror (Code Editor)
• Audit logging improved: IP logged for logins. User and group add/edit/delete events logged. Workflow activity logging includes user names. Security changes to elements logged
• Full support for multiple simultaneous media file providers

Developer features:

• When writing Razor Functions or User Control Functions you will now get nicely formatted compile error or runtime exception feedback with call stack, C1 Function name, line number and failing code lines preview.
• Your own static C1 Data Types (data types defined in pure code) which has the RelevantToUserType("Developer") attribute now show up on the Data Perspective in a new "Static Datatypes" folder. Below each data type you can browse data records and from there invoke an auto generated UI for CRUD.
• Create your own 100% customized UI for the "Function Call Editor" for your own C1 Functions.
• Use Razor to build custom C1 Console apps.
• You can now edit .sass files from the C1 Console
• You can now edit .asmx files from the C1 Console
• Control JPEG image compression (image quality) for resized images individually via ?q=... on media URLs or via the default value in Composite.config. You may also use ?q=... alone to control image quality of a full sized image fixing "user uploaded giant JPEGs" issues easily.
• C1 Function parameters generated from properties (Razor and User Control Functions) will now ignore properties where ‘set’ is private or the property has the attribute FunctionParameterIgnore().
• C1 Function parameters may now be of type Lazy<T> - Composite C1 will allow those to be set by C1 Functions of type Lazy<T> and T - and those nested function will not be executed unless you reference Lazy<T>.Value. This let you get "lazy parameters" in C# Functions, Razor Functions and User Control Functions.
• Better developer feedback: C1 Function names embedded into CLR call stack when executing - making exceptions much more informative as to which (perhaps nested) C1 Function failed, if an exception is thrown.
• Better developer feedback: the Function tester now shows entire exception info (stack trace, inner exceptions) when exception is thrown on "Result" generation - before only showed the exception message

Stability and performance:

• This release fixes bugs uncovered in the 4.0 release and introduces performance improvements in the C1 Console in particular and in the system in general. The release also improves on the existing high quality of system and error logging. Performance, stability and the very kind developer feedback have been on our minds when building this release (as always).

Other:

• Numerous bug fixes and minor improvements - for a more comprehensive list see https://compositec1.codeplex.com/SourceControl/list/changesets
