+title: Released Version 0.2
+excerpt: Release of Cyclone Scheme version 0.2
+---
+
+Today version 0.2 of the Cyclone Scheme-to-C compiler has been released: 
+
+[http://justinethier.github.io/cyclone/](http://justinethier.github.io/cyclone/)
+
+New features:
+
+- Added the following libraries from R7RS-large red edition (data structures):
+    - SRFI 1 list library
+    - SRFI 133 vector library
+    - SRFI 111 boxes
+    - SRFI 117 mutable queues
+    - SRFI 132 sorting library
+- Added SRFI 2, `and-let*`
+- Added `parameterize` from section 4.2.6 of R7RS to the `(scheme base)` library.
+- Added ` let-values` and ` let*-values` to `(scheme base)`.
+- Added `infinite?`, `finite?`, and `nan?` to `(scheme inexact)`.
+- Added string ports to `(scheme base)` - `open-input-string`, `open-output-string`, and `get-output-string`.
+- Added bytevector ports to `(scheme base)` - `get-output-bytevector`, `open-input-bytevector`, and `open-output-bytevector`.
+- Modified `cyclone` to also search the current working directory for built-in headers and libraries.
+
+Bug fixes:
+
+- Thanks to Mark Meyer, identified and fixed several segfaults in `write` and `display`. 
+- Updated `write` to display escaped character sequences (EG: `\t`) instead of literal characters.
+- Prevent C compilation errors when building a program that only contains basic primitives or a constant at the top level.
+- Fixed the compiler to allow application of a function that can take any number of arguments. For example:
+
+         ((lambda test (write test)) 1 2 3 4)
+
+- Updated `eval` to handle functions that take an optional number of arguments.
+- Updated `number->string` to omit leading zeros for binary conversions.
+- Fixed `apply` to use the proper semantics when receiving more than one data argument.
+- Changed the `assoc` and `member` functions to accept an optional comparison function, and modified both families of functions to be native Scheme functions instead of C primitives.
+- Allow libraries to contain multiple `import`, `begin`, and `export` sections.
+
+Cyclone consists of a compiler and interpreter written entirely in R7RS Scheme, as well as a C runtime. A large portion of the R7RS is supported including libraries, exceptions, continuations, and macros. 
+
+Thanks,
