The following is a summary of the changes in this release from the
previous one.


* Non-text items (e.g. a picture) can be used in a program as a contant
  value. The interaction window handles non-text for both input and
  output. When non-text is used in a program saved to disk, the file is
  automatically saved to disk in DrScheme’s binary format.

* Syntax checking has been improved, and the colors are now
  parameterized through preferences.

* These syntactic forms not yet supported: do without the step form and
  define-structure (use define-struct instead).


* The Analysis tool (MrSpidey) is temporarily unavailable in release 44
  and will reappear in a future release.

Known Problems

* DrScheme internally normalizes pathnames, resolving all links to
  absolute paths. This causes problems with systems that use

* Even in the R4RS language level, DrSchemd does not support
  case-insensitive identifiers.

* The `eval’ procedure is not supported.
