The new Subversion plugin has several major improvements. Now profiles are not tied to projects. If you use one repository path for several projects, there’s no need to create multiple profiles. All revisions will bind to each entity as per comments for these revisions.
Users mapping is much easier with the new UI.
JUnit, NUnit, Selenium Integration
JUnit, NUnit and Selenium plugins are merged into a single Test Import plugin that supports all these frameworks. Mostly, this is just a port for the old plugins.
Views with Full Inline Edit
New Views provide full inline edit. You can change titles and descriptions quickly, add or remove tags, update all the additional fields and even custom fields. There is no need for a separate Edit screen now.
New Views are included as popups to several screens: Kanban Board, Iteration Plan, Release Plan, Task Board, Prioritize, Assign People.
It’s possible to attach multiple files at once now. Moreover, you can just drop a file to an open popup view, and the attachment will be added automatically.
New Views are carefully crafted and polished. See them in action:
REST API Create, Update, Delete
Here are some quick examples: add a specific validation rule for a custom field, create a custom report with REST API, hide some UI elements based on your custom rules, fetch and display data from an external system, use custom colors for Kanban Board, etc.
Plugins SDK allows to create your own custom plugins quite easily. We created a Visual Studio template to jump start writing custom plugins. In general, you can write a simple plugin in about 1 hour.
