The goal of this version consists to be more R7RS compliant. All the R5RS functions which have been extended in R7RS are now conform to R7RS (for instance assoc and member accept now an optional parameter which is a compare function, vector->list accepts the start and end parameters, …)

  • Ports can now be binary or textual (standard ports are both)
  • New functions:
    • write-string
    • wite-shared & write-simple
    • functions to input and output bytevectors
    • read-u8 peek-u8 and u8-ready?
    • call-with-port
    • textual-port?
    • binary-port?
    • open-binary-input-file
    • open-binary-output-file
    • utf8->string & string->utf8
• Updated various functions to be R7RS compliant.
• Added the R7RS functions on bytevectors
• Added R7RS #true and #false constants
• Added R7RS exceptions
• Added R7RS system functions
• Upgraded the libraries embedded in STklos source tree
• Optimization of circular structure reading & writing
• New primitives - display-simple & display-shared - R7RS symbol=? - R7RS boolean=?
• Updated documentation
• Added SRFI-111
