+Starting from release version `1.4.3`, bumping the version to:
 
-- `1.4.4` would be a patch release for minor things such as fixing bugs.
-- `1.5` would be a minor release, for example adding some new features.
-- `2.0` would correspond to the _major_ release where results would no longer be backwards compatible.
+- **`1.4.4`**: A patch release for minor fixes such as bug corrections that do not modify how the user interacts with the pipeline. Examples:
+  - Inserting a missing argument to a process command line
+  - Updating a container build version of a tool that is otherwise the same version of the tool itself
+- **`1.5`**: A minor release that adds new features without changing existing functionality. Examples:
+  - Adding a new parameter that adds new functionality/options to an existing module
+  - Add a new optional or default process that does not change the way the user interacts with previous steps of a pipeline
+- **`2.0`**: A major release where execution interaction, inputs or results are no longer backwards in terms of pipeline user interaction. Examples:
+  - Renaming or deprecations of existing parameter(s)
+  - Change to input sample sheet specification (adding, dropping, renaming of mandatory columns) or change the input samplesheet specification.
+  - Note that a major release DOES NOT necessarily require new functionality
