I know this definition mostly comes from the linked hybrid mode page, but I think both could be simplified for clarity, as an example:

Hybrid mode, or a hybrid Self-Managed distribution, allows you to run an separate instance of the Connectors runtime in a self-managed or local fashion. This instance can be attached to either a SaaS cluster, or another Self-Managed cluster with its own Connectors runtime, to apply changes or isolate the instance from the public internet.

This has the added benefit of giving a useful definition to the times in the Connectors pages we use "Hybrid/Self Managed" as a description.

Somewhat separately, is this release number useful here (and on the linked hybrid mode page), or does it also need additional context? I am not sure if it's easy for someone to know what connectors release they're on, or what version of Camunda 8 that might apply to.

@conceptualshark I've applied a few of your suggested changes, and agreed, removed the release number from the glossary description within the scope of this issue 👍

Looks clean to me!
