We uploaded a new HTML Client SDK Fling today on the vSphere HTML5 Web Client Fling page.
Click on the drop down on the left hand side and select html-client-sdk-6.5.0-<build>.zip. See also the attached PDF for an overview.
This new SDK contains everything you need to build HTML plugins that are compatible with both vSphere Web Client (6.0 and 6.5) and vSphere HTML Client!
If you already have an HTML plugin using a previous SDK please try out this new HTML SDK and let us know if you run into any problem. See the documentation included in the SDK for detailed upgrade steps.
We will update the SDK Fling on a regular basis to improve documentation, samples and fix problems.
Start using it today to get your plugin ready in time for with the release of vSphere HTML Client later this year!
