Version 6.2 of the Notes on Diffy Qs is up on the website.

[Jiří Lebl]

This is a very minor update, mostly to fix errata, but there have also been a bunch of minor improvements throughout.

See http://www.jirka.org/diffyqs/changes.html

In other related news, the WebWorK problem set is slowly getting more mature.  If you are using it and have found any errors do let me know!

Best,

Jiri
