JDirector 2.2.1_imca43.1 has been released. This update fixes a usability issue in manual diffraction centering.

• Only allow the characters "a-zA-Z_.-" in manual diffraction center "raster images folder" path elements. This avoids cryptic diffraction center errors caused by the inability of the Dectris Pilatus camserver software to handle paths containing certain characters (e.g. the space character). (The set of characters the camserver software can handle is undocumented.)
