     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
+              so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
+  - requires an additional time level that is stored in the pickup
+  - you can start with AB2 from a pickup without this time level with
+    pickupStrictlyMatch = .false.

 o pkg/cheapaml:
