JDirector 2.2.1_imca41 has been released. This update adds support for entering X-ray beam attenuation as transmission and other improvements.

• Added support for entering X-ray beam transmission instead of attenuation for users who would prefer to think in terms of transmission. This applies to the scan editor, the manual diffraction centering configuration, and the job sample table.
• Fixed the job sample table to use correct detector distance limits. Previously, the limits were hard-coded which was wrong. Now the limits are obtained from the instrument server.
• Improved log messages. This involved fixing a case where an undefined value was printed as null, where extraneous trailing punctuation was used, and where an exception trace was unnecessarily printed for a diffraction center that terminated due to a low-score cutoff.
