Legacy

thin-edge.io 1.0 introduced a set of breaking changes that might affect plugins and extensions implemented on previous versions.

In most cases, a compatibility layer has been introduced to smooth the transition. For instance, any measurement published by an extension on the former topic tedge/measurement is republished by the tedge-agent to the topic te/device/main///m/ which is dedicated to untyped measurements for the main device.

However, the compatibility layers don't address all the breaking changes and, in any case, they will be deprecated medium-term. Here are the developer guides to port a legacy extension to the new thin-edge.io API.
