We have adopted the development policy that we are going to try to ease

Tom Henderson <tomh@tomh.org>

The goal is that users who encounter a problem when trying to use older

Tom Henderson <tomh@tomh.org>
parents:

    27
code with newer code should be able to consult this file to find

Tom Henderson <tomh@tomh.org>
parents:

    28
guidance as to how to fix the problem.  For instance, if a method name
16005bad2e0b Add CHANGES.html
Tom Henderson <tomh@tomh.org>
parents:
diff changeset
    29
or signature has changed, it should be stated what the new replacement

name is. </p>

Note that users who upgrade the simulator across versions, or who work

directly out of the development tree, may find that simulation output
16005bad2e0b Add CHANGES.html

    34
changes even when the compilation doesn't break, such as when a
