+checkpoint55
+o up-to-date adjoint of previous breaks
+  - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
+  - global_ocean_ebm: adjoint still needs fix (TLM ok)
+  - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
+  - carbon: * remove tr1-related adjoint verification
+            * add ptracer as control variable
+o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
+  (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
+
 checkpoint54f_post
 o in verification/carbin/ remove experiment related to
   ALLOW_PASSIVE_TRACER (array tr1 etc)
