post	Released Cyclone Scheme 0.3	Cyclone Scheme 0.3 is now available.

New features in this release:

• Improve performance by inlining numeric arithmetic and comparison operations.

• Reverted assq, assv, memq, and memv back to primitives for improved performance. In addition the compiler was modified to allow for more efficient compilation of assoc and member.

• Improved library support to recognize all of the import set forms: only, except, prefix, and rename.

• Allow explicit renaming macros to be declared interactively. This is the first limited support for calling define-syntax from eval.

• Added the get-environment-variables function from R7RS.

• Added support for the following SRFI's:

  • SRFI 106: A basic socket interface
  • SRFI 128: Comparators

Bug fixes:

• Improved macro hygiene support to properly rename temporary variables in the let-values macro.
• Improve output of error by using write to output objects as they are represented in memory.
• Check for duplicate lambda parameters during compilation.
• Fixed an error that was being raised when calling (random-source-randomize! default-random-source) when using SRFI 27.
• Raise an error if list->string encounters a list element that is not a character.
