This release introduces the following key changes:

Added

• config: experimental topic based filtering of log messages per logging sink via Experimental/EnabledTopics and Experimental/DisabledTopics. Log messages are tagged with a topic that classifies their origin (e.g., Asio, Ethernet, Participant, User).
• docs: added description of the experimental logging topics, including the list of topic names currently assigned by SIL Kit components.

Fixed

• core: on peer shutdown, the disconnected peer is removed from the pending subscription acknowledges. Otherwise, participants could wait indefinitely for acknowledges that will never arrive.
• config: the participant configuration is now validated against the schema. Previously, only included configuration files were validated, the root configuration was not.
• config: added missing entries to the participant configuration JSON schema and the schema validation (e.g., Experimental/Metrics/UpdateInterval, RpcClients/RpcChannel, RpcServers/RpcChannel).
• api: the public header silkit/services/logging/string_utils.hpp no longer includes internal headers.
• config: experimental Experimental.TimeSynchronization.DynamicSimulationStep to enable dynamic
  simulation step sizes, aligning each simulation step to the minimal step among all synchronized
  participants. Tri-state: true requests it for the whole simulation, false opts out, and leaving
  it unset follows the network. Off by default.

Changed

• config: default format of file logging is set to JSON. Set "Format: Simple" in the sink to get previous behaviour.
• docs: added description of the logging "Format".
• docs: added deprecation warning for Ubuntu 20.04
• build: the CMake targets only expose the top-level include directory instead of internal include directories.

Fixed

• config: a mapping that is mistyped as a YAML sequence (e.g. a stray leading - turning HealthCheck into a list) is now rejected with a clear error instead of being silently accepted.
• config: a configuration containing multiple ----separated YAML documents is now rejected with a clear error. A single leading --- remains valid.
• orchestration: setting a simulation step duration of zero now raises a SilKitError instead of being silently accepted.
