Differences between WeBWorK 1 and WeBWorK 2

An important aspect of WeBWorK 1 was that you could not do anything with problems unless they were part of a "built" problem set. This was a fairly limiting feature, and it has changed dramatically. In WeBWorK 2,

• there are various ways to look at, write, test, and manage problems which are not part of built sets.
• you can also manage a problem set without it being built
• you can have a set "built", but not visible to students

The term "build", when it comes to problem sets, has been changed to "assigned". This would probably been a better term all along.
