This is a summary of the recent changes to DrScheme in the
SVN archive. You may have some of these changes already;
typically each change is committed as it happens and these
emails are only sent when the list gets long enough.

  . Added two new keybindings to DrScheme (in Scheme mode):

    c-c; c-o move-sexp-out: the sexpression following the insertion
    point is put in place of its containing sexpression.

    c-c; c-l insert-let-binding: wraps a let around the sexpression
    following the insertion point and puts a printf in at that point
    (useful for debugging)

  . Case-insensitivity is now available in DrScheme's search box,
    courtesy of Jens Axel Sogaard. Thanks!

  . The image.ss teachpack now uses smoothed images.

  . drscheme-language-positions and
    drscheme-language-readers now allows relative paths for
    language module specifications.

  . Added `this', implicitly bound in ->r and ->pp contracts
    when used inside `object-contract'

  . union is now deprecated in favor of or/c. It's the same
    combinator, but it matches other names in the contract library.
