Features Added

Bug Fixes

Fixed a bug where problem.materials.append_renumber would double add a material to problem.data_inputs (#516).
Fixed bug where material-level library specifications (e.g., m1 plib=84p) could not be fully parsed (#521).
Fixed bug with shortcuts right after another shortcut (e.g., 1 2M 3R) not being properly recompressed on export (#499).
Fixed bug with shortcuts in cell geometry definitions not being recompressed on export (#489).
Fixed bug where leading comments were not always transferred to the appropriate input. (#352, #526).

Fixed method of linking Material to ThermalScattering objects, avoiding a very expensive O(N :sup:2) (#510).

Deprecations

Marked Material.material_components as deprecated, and created migration plan describing what to expect moving forward (#506).
