DrScheme Release Notes ---------------------- Current Release: 44 Release Date: September 9, 1996. Send bug reports to: firstname.lastname@example.org The following is a summary of the changes in this release from the previous one. DrScheme -------- * 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). Analysis -------- * 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 automounting. * Even in the R4RS language level, DrSchemd does not support case-insensitive identifiers. * The `eval’ procedure is not supported.
