Supported until 4 December 2020.


Diffusion 6.2 was first released in November 2018.

This release added a new update API, including a stateless set method, session locks in all clients, and easier creation of missing topics. It also improved compression performance and added a new fetch API for retrieving topic values and specifications, making it easier to page through large data sets.

Diffusion 5.9 was first released in September 2016.

This release brought JSON and binary topic support to the Apple API, included improvements to the automatic fan-out capability, and added TypeScript support to the JavaScript API. This is the last release to support the classic client API.
