+
+<!-- 	Engine - Adding ServiceDetails to ExecutionContext - Patch 2025.3.26111 into 2025.9.26121	 -->
+##### Added ServiceDetails to ExecutionContext
+
+The `ExecutionContext` now contains the `ServiceDetails`, providing information about the service that the execution is running on, including
+
+* `Name`
+* `Type`
+* `Version`
+* `PartitionId`
+* `ReplicaOrInstanceId`
+* `ProcessId`

+
+<!-- 	Engine - Block logging controlled per block - Patch 2025.3.26111 into 2025.9.26121	 -->
+##### Added ability to configure block logging on each block
+
+All blocks now have a new advanced `Logging` setting that lets you control whether the [Block][Blocks] logs its activity. You can choose to always log by setting the `enabled` property in `Logging` to `true`, to never log by setting it to `false` or to have logging controlled by
+the block logging API setting by leaving it blank or setting it to `null`.
+Variables can also be used to set the `enabled` value, allowing you to dynamically turn logging on or off at runtime.

+<!-- 	Flow Engine - Support default literal - Patch 2025.3.26211 into 2025.9.26121	 -->
+##### Improved Handling of Default Values in the Expression Editor
+
+When using the expression editor inside block properties, leaving an inner property blank could previously cause errors if the system could not determine the correct default type.
+To prevent this, the expression editor now automatically inspects the parent type and works out the appropriate default value during translation.

+<!-- 	Authorisation Service - Distinguished Name filter to reduce the number of roles in the token - Patch 2025.3.26211 into 2025.9.26121	 -->
+##### Added LDAP Group Filtering for Role Claims
+
+The [{{% ctx %}} Authorisation Service][] now includes a new optional setting, `DistinguishedNameFilter`, in its `LdapAuthSettings`. This setting allows you to control which LDAP groups are included in a user’s role claims.
+If a regular expression is provided in DistinguishedNameFilter, only group names that match this pattern will be added to the user’s role claims.

+<!-- 	CORTEX Interaction Portal - Deep link ProcessID - with extra query parameter (such as ?open=true) - Patch 2025.3.26111 into 2025.9.26121	 -->
+##### Added support for filtering and opening task by process id
+
+Support was added for filtering the Process Dashboard by providing the `ProcessId` as a query parameter.
+You can now also open a task by `ProcessId` using the `Open` query parameter (e.g `https://server.domain.com/cortexinteractionportal?ProcessID=ae40ced8-9a81-4c46-af85-f5ba35f48169` or `https://server.domain.com/cortexinteractionportal?ProcessID=ae40ced8-9a81-4c46-af85-f5ba35f48169&Open=true`)

+<!-- 	Trigger Service - Calculate the Generic and Specific values correctly when the Generic value in the Oid is 5 - Patch 2025.9.26121	 -->
+##### Enhanced the handling of untranslated SNMP v1 Traps
+
+For SNMP v1 traps without a matching MIB, {{% ctx %}} now extracts trap details directly from the trap OID when the `GenericTrapType` is valid (0–6).
+In these cases, the `GenericTrapType`, `SpecificTrapType`, and `EnterpriseId` are populated automatically.
+If the value is outside the valid range, these fields are set to null to avoid incorrect data.

+##### Partial Translation for unrecognised SNMP varbinds
+
+{{% ctx %}} now attempts to partially translate SNMP varbinds when a full translation isn’t possible.
+If the MIB contains a valid `FilePath`, the known part of the varbind is translated and the remaining unmatched section is left as‑is.

+
+<!-- 	Execution Service - Regulate cache access to package management interactions - Patch 2025.3.26111 into 2025.9.26121	 -->
+##### Improved Execution Service concurrency and flow translation
+
+The [{{% ctx %}} Execution Service][] now uses semaphores to ensure the same flow isn't translated multiple times when executed concurrently for the first time.  
+Additionally, various performance optimisations have been made within the service.

+
+<!-- 	Observability - Set Retention Period for Grafana Loki - Patch 2025.3.26111 into 2025.9.26121	 -->
+##### Set retention period for Grafana Loki
+
+Added a retention period to Grafana Loki to ensure that Logs do not continue to grow exponentially.
+Previously logs were kept indefinitely in Grafana Loki and this would have consumed vast amounts of disk space.
+The retention period is configurable based on the retention that is required, with the default set to 12 months.

+#### Installation
+
+<!-- 	Installation - Recover lost Node - 2025.3.26211 into 2025.9.26121	 -->
+##### Improved Node Recovery for Cluster Machines
+
+Cluster nodes can now recover seamlessly after being completely wiped.
+When a machine is rebuilt and brought back online, it automatically rejoins both the RabbitMQ cluster and the [Service Fabric][Service Fabric] cluster without requiring manual intervention.
+This ensures faster, more reliable recovery and reduces operational overhead during node restoration.

+##### UTF‑8 encoding support for Non‑ANSI characters in configuration files
+
+{{% ctx %}} now saves key configuration files in UTF‑8, ensuring certificates with non‑ANSI characters are handled correctly during installation and can be read by [{{% ctx %}} API Gateway Service][].

+##### Backup & Restore Support for Reliable Collections during Single‑Server Upgrades
+
+During a single‑server upgrade, all reliable collection data is now automatically backed up before the upgrade starts, and restored after the upgrade completes, preserving data that would have previously needed to be restored manually.

+
+* {{% ctx %}} Upgrade Scripts
+
+<!-- 	Upgrade - Automate Pre upgrade checks - Patch 2025.3.26211 into 2025.9.26121	 -->
+#### Enhanced pre‑upgrade health checks for Service Fabric and RabbitMQ
+
+Upgrades now stop if Service Fabric or RabbitMQ are not fully healthy. Nodes that are down, in error, or missing from the cluster will prevent an upgrade from happening until they are fixed.
+RabbitMQ queues are also checked, with automatic fixes for missing members and noproc states.
+If error queues contain messages, you’ll be prompted to review or automatically export and clear them before continuing.
