VMware is announcing that the upcoming vSphere release will be the terminal release for two older sets of vSphere client APIs -- the vSphere Flex client APIs and the current set of HTML client APIs (also known as the Bridge APIs). A new set of vSphere client APIs that are designed to scale and support the use cases and improved security, design, and extensibility of the vSphere HTML client are included as part of today's vSphere RC release.
We are also announcing deprecation of webplatform.js, which will be replaced with an improved way to push updates into partner plugin solutions without any lifecycle dependencies on vSphere client SDK updates.
Note: If you have an existing plugin solution to the vSphere client, please upgrade Virgo server according to the information included in the vSphere RC release. Existing vSphere client plugins will not be compatible with the upcoming vSphere release without developers taking this upgrade action.
