Upgrading your PLT v208 code to work with PLT v299

Problem

PLT v299 (soon to be PLT v300) is different from PLT v208 (its predecessor), and code that works with v208 needs work in order to work with v299. This 'recipe' attempts to provide summaries and links regarding the changes -- An upgrade FAQ, if you will.

Solution

Additional information about changes in MzScheme, MrEd, and DrScheme is available in their history files:

You may also be interested in the chronology page, which includes announcements up through 299.12.

Notes from Doug Orleans:

These are notes made by Doug Orleans after upgrading a substantial block of servlet code to 299:

Now that I've finally gotten all my servlets to work with v299 again, here's a list of the changes I ran into that seems to be un(der)documented. Hopefully this will make it easier for anyone else who might be planning follow the same path. I already posted about some of these but I'm collecting them all here in one place for the record. However, I'm leaving out a few bugs (which I've reported via help-desk), on the assumption that they'll be fixed before v300 so you won't have to think about a workaround.

Arguably some or all of these should just be handled silently.
