Because of the recent changes to the Creative Cloud policy, I am redirecting this page to the official Adobe post
http://terrywhite.com/5-myths-about-adobe-creative-cloud/
This will help keep the post current and in sync with the latest announcements at Adobe. If you have visited this post in the week later to March 06, please read the updated blog post from Terry White. Apologize for any confusion.
In broad terms, Insert options have been added, deprecated, or re-organized to streamline workflows, reduce clutter, and ensure compliance with the latest and most popular trends in web design. To help you focus on the page and avoid distraction from colorful elements in the user interface, color options for Insert icons have been deprecated.
While you may need to re-familiarize yourself with the user interface changes in the short term, we are confident that you will recognize their value as you get up to speed with the new workflows.
The reasons for re-organizing the Insert panel in this update are listed below.

From the page Adobe Creative Cloud / FAQ
Is Creative Cloud a replacement for Adobe’s traditional creative products and suite editions?
Adobe believes that Creative Cloud is a better way to get your desktop tools because you get access to the latest updates and features as soon as they’re available, plus services that tie the new publishing workflows together. Adobe will continue to develop and sell individual CS products, and customers can purchase them through the Adobe online stores and select retail and online stores.
Are there any differences between the Creative Suite software included in my Creative Cloud membership and the software I buy in the box?
Yes, the software included in Creative Cloud membership is different from the software you buy in the box. It gives you everything in the traditional licensed version plus exclusive access to new features. This means that as soon as our engineering teams can finalize new features — such as the features we recently released for Illustrator, and many other new features to come — we will release them through special software editions available only to paying Creative Cloud members. So no more waiting between major releases to get new features.
See the blog post Dreamweaver extensions don’t appear after updating Dreamweaver to 12.1
Your custom keyboard shortcuts and Favorites in the Insert icon panel are lost after an update. For icons, you will have to note down your Favorites before you update, and add them again after you complete installing the update.
For keyboard shortcuts, ensure that you export them before you install the update.
After you upgrade, refer to the exported file to set the shortcuts again.
The menu items in Dreamweaver are listed in the menus.xml file. When you add an extension, an entry for the extension is made in the menus.xml file.
Menu organization is changing in this release because a new menus.xml file will overwrite the previous menus.xml file. Because the previous menus.xml file – which contained Dreamweaver extensions – will be overwritten, menu entries corresponding to these extensions will no longer be displayed after the update.
To display previously installed extensions, do the following:
1. Click Help > Manage Extensions.
2. In the Adobe Extension Manager, use Ctrl-click or Shift-click to select extensions that you want to enable.
3. Right-click and select Disable.
4. Right-click again, and select Enable.
This blog article discusses the improvements to FTP file transfer in Dreamweaver CS6.
Dreamweaver uses multi-channel transfer to simultaneously transfer selected files using multiple channels. Dreamweaver also allows you to simultaneously use the Get and Put operations to transfer files.
If there is sufficient bandwidth available, FTP multi-channel asynchronous transfer considerably speeds up the transfer process.
Multi-channel transfer
You can now select more than one file for FTP transfer. By default, three files are lined up for Get and Put operations. The files that are currently being transferred are indicated by a green download arrow icon. The files pending download are indicated by an orange download arrow icon.

When you move your mouse over the file being transferred, the percentage of content transferred is displayed. A red error icon indicates files that were not transferred.
Asynchronous transfer
You can now simultaneously perform the Get and Put operations on different sets of files. For the status of large files being transferred, check their status in the Details section of the Background File Activity dialog box.
FTP log details
Adobe recommends that you do not click the Cancel button in the Finishing Get/Put Operation dialog when the operation is in progress. During the Finishing operation, information about files transferred is captured in the dwsync.xml file. Unlike in previous versions of Dreamweaver where the XML file was updated after every file transfer, Dreamweaver now updates the file at the end of the transfer process.
When you perform the Get/Put operation later, Dreamweaver uses the information in the dwsync.xml file to transfer only those files that are new/changed. It ignores files with no updates. This considerably speeds up the transfer process.
Note: The progress bar now indicates the number of files being transferred and not the size of the files as in previous versions of Dreamweaver. For information on the extent of the file transferred, move your mouse over the file being transferred. The information is displayed in the tooltip.

You can now perform the following operations when the asynchronous transfer is in progress:
These operations have a higher priority than the transfer process. The higher priority allows you to quickly perform these operations when the transfer is in progress without having to wait for the transfer process to complete.
Separate icons for remote server and testing server
In the collapsed mode of the Files panel, it is difficult to identify whether Dreamweaver is connected to the remote or testing server. Separate icons for remote and testing servers now help identify the type of connection. The icon for connection to the testing server is 
and that for remote server is 
.
Note: The above enhancements to FTP transfer work only for FTP and FTPS (Implicit and Explicit).
