+For `Subworkflow Input` nodes with primitive number types, users can now set the value directly in the `Subworkflow` node without a link to separate node. 
 This allows for more compact workflows when you simply want to set a number for the inner workflow.
 When an node is linked to the input of such a node, the linked node value will take precedence over the set value.
 The value input can also be disabled; the linked input of the inner input will use as fallback value.

 ### Version History
 
+- v1.2.3 - (re)loading an inner workflow with links updates no longer disconnects all input links; they are now preserved when possible.
 - v1.2.2 - Fixed a bug where inner node validation exception were raised due to removal of initial static output slots. 
 - v1.2.1 - Removed the maximum number of inputs and outputs on the `Subworkflow` node (was previously set to 8).
-- v1.2.0 - Added manual value entry for primitive `Subworkflow Input` input nodes on the `Subworkflow` node. Check README features section for details.
+- v1.2.0 - Added value entry for primitive `Subworkflow Input` input nodes directly on the `Subworkflow` node. Check README features section for details.
 - v1.1.0 - Added `Subworkflow Modifier`, `Subworkflow Modifier Source` (+ from URL) nodes. Combining these nodes in inner and outer workflows allows for circular links between an inner workflow input and output, without circular reference problems. 
 - v1.0.1 - UI only nodes are now supported in inner workflows, no longer raising and error when loading.
 - v1.0.0 - Initial release of the four custom nodes and workflow loading and execution behavior.
