- and precise release notes
- and add a draft usage example

Refs #22197

Refs #22197

- added test to compare if input workspaces get modified when running Stitch1D. Unfortunately this is the case for point and binned data.

Refs #22197

- with and without dx
- sort & join
- scaling factor

Refs #22197

Refs #22197

Refs #22197

- new method scaleWorkspace which reinserts Dx values for point data
- deleted MantidDataObjects/WorkspaceSingleValue.h from Multiply and Divide
- introduced new class variables m_scaleFactor and m_errorScaleFactor; those values will now be initialised by 1.0 (the default value) and not 0.0 as before.
- deleted unused tool-tip texts (Optional.)
- ConjoinXRuns output workspace property is a Workspace and not a MatrixWorkspace -> dynamic pointer cast
- unit tests for histograms pass
- MantidPlot executes for point data example from unit test
- unit test for point data fails (SortXAxis, Python algorithm, not registered!)

Refs #22197

Includes:
  - using stack allocation for tcp server
  - removal of unnecessary mutex
  - unused includes removed

If the source stops sending data then the cancellation
request has to wait until the receive loop completes
before it is checked. Add the check in more places
to improve the responsiveness.

- put each declaration of a variable in a single line
- using const auto  & to get x, y, e, dx
- directly set the size and xerrors in setPointStandardDeviations

Refs #22218

Refs #22197

- shorter tests by using std::vector equality check capacity
- add test for !hasDx capability

- in WorkspaceCreationHelper: do not overload create2DWorkspaceBinned but use new method create2DWorkspaceNonUniformlyBinned

Refs #22218

- documentation modified (description, usage exmple)
- clang
- performance test ConjoinXRunsTest (<6 sec with dx, without dx it would be 0.1 sec faster)
- fix ConjoinXRuns (bracket did not close correcly)
- add unit test without dx values in ConjoinXRuns (all other tests run with dx)
