Release notes for version 1.5 Additions: Comprehensive Unicode support was added. See the manual for details. An implementation of SRFI 19 was added. (thanks to Emilio Lopes) Syntax-rules now supports vector patterns and templates. The ,bound? command now produces more output. (thanks to Taylor Campbell) Changes: Many of the POSIX procedures that accepted or returned strings previously now accept or return OS strings. See the manual for details. The ,build command now accepts a procedure that will be called with a list of OS strings rather than regular strings. The ascii->char and char->ascii procedures from the ascii structure covers only ASCII (codes 0-127) now. (Previously, the range included 128-255 as well.) Bug fixes: A bug with package mutation was fixed. (reported by Taylor Campbell) Release notes for version 1.4. Jump to top of page.
