agents/satellites not accepting configuration anymore, or not reloading,
please upgrade.
* Bugfixes

– Never accept authoritative config markers from other instances
– This affects setups where agent/satellites are newer than the
config master, e.g. satellite/agent=2.11.0, master=2.10.

set #7514

agents #7526

Beast, Coroutines

still NOT-OK

delete signing requests
– Add new commands and missing attributes
* Windows

– Technical Concepts: TLS Network IO, Cluster Feature HA, Cluster
Config Sync
– Development: Rewritten for better debugging and development
experience for contributors including a style guide. Add nightly
build setup instructions.
– Packaging: was integrated into the Development chapter,
being available at too.
