 - Updated the LRO photometry application Lronacpho, to use by default the current 2019 photometric model (LROC_Empirical). The model's coefficients are found in the PVL file that exists in the LRO data/mission/calibration directory. If the old parameter file is provided, the old algorithm(2014) will be used. This functionality is desired for calculation comparisons. Issue: [#4512](https://github.com/USGS-Astrogeology/ISIS3/issues/4512), PR: [#4519](https://github.com/USGS-Astrogeology/ISIS3/pull/4519)
 - Added a new application, framestitch, for stitching even and odd push frame images back together prior to processing in other applications. [4924](https://github.com/USGS-Astrogeology/ISIS3/issues/4924)
 - Added changes to lronaccal to use time-dependent dark files for dark correction and use of specific dark files for images with exp code of zero. Also added GTests for lronaccal and refactored code to make callable. Added 3 truth cubes to testing directory.  PR[#4520](https://github.com/USGS-Astrogeology/ISIS3/pull/4520)
+- Added failure for images with missing original label in caminfo. [#4817](https://github.com/USGS-Astrogeology/ISIS3/pull/4817)

 ### Changed
 - Updated the LRO calibration application Lrowaccal to add a units label to the RadiometricType keyword of the Radiometry group in the output cube label if the RadiometricType parameter is Radiance. No functionality is changed if the RadiometricType parameter is IOF. Lrowaccal has also been refactored to be callable for testing purposes.
