 Changes
 =======
+v3.5.6
+- routing_manager_client
+  - Forcing the ON_AVAILABLE log and send subscription of requested services even if availability was
+    previously known.
+	- Remove pending subscription entry right after calling on_subscription from application impl - race
+    condition
+	- Add missing mutex on request_debounce_timeout_ck and reset request_debounce_timer_running_ if
+    requests_to_debounce_ is empty - race condition (issue: missing request)
+	- lock registration_state_mutex_ before sending subscribes and unsubscribes - race condition
+	- re-request service availability triggers from the routing host when a client loses the connection
+    to a service provider
+
+- routing_manager_impl
+	- Convert pending_sd_offers_ from vector to set to avoid repeated service entries.
+
+- routing_manager_stub
+	- Send a `config_command` to share the _client hostname with the _target application. the
+    config_command message is only sent after the routing_info is sent, thereby guaranteeing
+    that the routing_info is processed first.
+	- Send ADD_CLIENT command to all the client registered, without considering if they are
+    requesting services from this client.
+
+- routing_manager_base
+	- Added a change to add_known_client so that the order of calling config_command and
+    routing_info_command would not matter. This change only has impact when the clients adds itself
+    as a known_client and was made to safeguard its hostname.
+
+- endpoints
+	- local comunication
+		- Force endpoint to perform port assignment when local network interface becomes unavailable.
+		- Check on local_tcp_client and local_uds_client if socket is open before sending.
+		- Do not call shutdown_and_close_socket if socket state is connecting - race condition
+		- A condition variable was implemented on local-tcp_client endpoint to notify the stop process
+      to exit the 10ms wait if an EOF is received in receive_cbk, since the queue is cleared in this case.
+    - Ensuring the lifetime of message_buffer_ptr on uds.
+	- external communication
+		- A state machine was created to cascade the stop -> init + start The goal was to ensure that
+      the udp_server endpoint waits on both unicast and multicast  stop, and after they are both stopped,
+      and the flag restarting is set, the init and start can be called. (issue: Bad File Descriptor)
+		- Syncronize the join and leave process of udp server multicast sockets. also (issue: in some situations
+      after STR, vsomeip will not join the multicast group used by service discovery).
+		- leave and join multicast address only starts when network is ready. (issue: join/leave multicast was
+      causing CPU load, because this process starts when network is not ready).
+		- Remove use of linger-with-timeout in tse, which fixes blocking socket operations
+		- Ensure "shutdown_and_close" is called on "stop".
+	- local and external communication
+		- Endpoints would start every time find_or_create_local would execute, even if endpoint already existed.
+		- Fix is_sending_ status
+		- Increase mutex_ scope to include was_not_connected flag on connect (issue: REMOTE_ERROR on response)
+		- cancel_and_connect_cbk was updated to only report the connection as successfully terminated when
+      cancel_and_connect_cbk is called without error. Previously, it was reporting the connection as successfully
+      terminated even when there was a connection error, preventing the endpoint from being.
+restarted.
+
+- netlink
+	- Removes the interface index when we get a RTM_DELLINK.
+	- Added an option to consider the reset of sd_route_set_ when interface goes down. This is enabled by default.
+
+- security
+	- For each received response/notification, call is_client_allowed_to_offer to check whether the sending client
+    is allowed to offer the service. This is done only for internal TCP communication; for UDS the check is done
+    with the bound client.
+
+- service discovery
+	- Fix multicast threshold for initial events.
+	- Stop find/offer debounce timers when the service discovery is stopped.
+	- Added a mecaism on start of SD, to try rejooin the multicast address if any message was received by 1.1s
+    (default timer) (issue: in some situations after STR, vsomeip will not join the multicast group used by
+    service discovery).
+
+- IO threads
+	- To mitigate IO threads exit and stalled threads, a solution in which the io_context object processing is
+    ran for determined duration was developed. This feature is disable by default and can be enable by
+    configurations.
+
+- configurations
+	- Added configuration to enable io thread mitigation.
+	- Enable configuration of client-specific debouncing.
+	- Allow global configuration of maximum (additional) dispatchers and dispatch time.
+	- Unspecify catch exception for boost exceptions.
+	- Added configuration to consider the reset of sd_route_set_ when interface goes down. This is enabled by
+    default.
+	- Enable global configuration of request debounce time.
+	- Support multiple IPsec activation files per connection.
+
+- application_impl
+	- Fix host assignment with non-local routing: add SO_REUSEADDR to the non-local routing host check
+
+- runtime
+	- Remove the get_mutex_ from runtime_impl - This mutex is not needed, as the static initialization of the
+    shared_ptr is atomic. (issue: tombstone in application shutdown)
+
 v3.5.5
 - Fix build issue on Ubuntu 24.04
 - Fixing change that was introduced on Fix for Find messages commit
