 >Note: The first time a version of Workbench is started on your machine an install-specific environment is setup.
       This can take a few minutes, so please be patient. A message stating `Testing for python using ...` will be presented in the terminal from which Workbench has been launched.
 
+## NEAMS Workbench 5.5.1
+
+### Added:
+- SAM displaced mesh alternate runtime invocation via Run > displaced-mesh-only menu item.
+- Language server client logging. Export WB_LSP_LOGGIN=YES prior to launching Workbench to enable logging language server logging to the terminal.
+- Ability to toggle MOOSE-application INL-HPC current session core count via specifying MOOSE_NPROCS environment variable and value in the Run Configuration dialog window.
+
+### Changed:
+- Disabled job `Kill` Messages panel context menu option for remote jobs. This option killed the runtime process not the job which is almost never what the user actually want. Instead, use the `Terminate` Messages panel context menu option.
+- Runtime `Kill` signal processing to signal subprocesses bottom up instead of top-down to address changes observed in operating system process hierarchy presentation.
+
+### Fixed:
+- ParaView `Visualization GUI` vertical screen requirement pushing Workbench `Validation` and `Messages` panel off the bottom of the remote desktop (E.g., INL HPC desktop). A vertical scroll bar is now presented to prevent ParaView `Visualization GUI` from requiring too much vertical space.
+- Keyboard shortcut collisions for Document/Data saving, file open, operation undo and redo, between Workbench's text editor and ParaView's `Visualization GUI`
