- Added a new application, isisimport. The application is designed to be a replacement for many of the mission/instrument specific import applications. It does not contain the templates for those applications at this time. It uses a templateing engine instead of the translation files.
- Added a new dark current correction to hical that works with the higher temperatures recent images are captured at. Use the new config file, $ISISDATA/mro/calibration/hical.0023_darkrate.conf, to enable the new dark current correction over the old dark current correction. Runs of hical without the new dark current correction will also produce an extra line in the output log indicating that the ZeroDarkRate module is disabled.

- Added the ability to bundle adjust CSM models in jigsaw. Use the new CSMSOLVESET, CSMSOLVETYPE, and CSMSOLVELIST arguments to specify what you solve for. [#4537](https://github.com/USGS-Astrogeology/ISIS3/pull/4537)
- Added the ability to search filenames in measure's drop down boxes in Qnet Point Editor. [#4581](https://github.com/USGS-Astrogeology/ISIS3/issues/4581)
