Activity Library: Reference Release-Note #3: The AutoDrop option for any concurrent groups is automatically set to the same as the schedule in which it is contained. (Any existing setting of the option on the concurrent group type is ignored.) So, in 1.0.2, if you didn't set the AutoDrop flag for a concurrentGroup initialized under a schedule, it defaulted to NO or false.
Random Library: 13, 14
Reference Release-Note #13 This release includes Random v0.7, written by Sven Thommesen. This version adds several new bit generators and distributions and rearranges the library. (Ref. $SWARMHOME/src/random/docs/WHATS.CHANGED.in.0.7 and WHATS.NEW.in.0.7)
Reference Release-Note #14: With the addition of the ability to make use of the default random number generators and distributions such that different runs start with a different seed or with the same seed, the static seed was changed. This means that runs with 1.0.3 will not match runs made with the static seed for 1.0.2. This is acceptable because the use of the default generators and distributions is DEPRECATED.
