post	Released Cyclone Scheme 0.21	Various bug fixes and continuous integration support for FreeBSD.

Features

• Alex Arslan modified the Travis script to add support for FreeBSD continuous integration.
• Added additional functions to (srfi 132): vector-find-median!, vector-find-median, vector-select!, vector-select, and vector-separate!.

Bug Fixes

• Updated the Dockerfile to use a non-interactive install. This prevents build problems with the official image on DockerHub.
• Improved (scheme lazy) to allow force and make-promise to accept an argument of any type. Improved representation of promises to more precisely differentiate them from other objects.
• Updated (scheme lazy) such that force will recursively force promises.
• Add type checking to record type accessor functions. We now raise an error if the passed object is of the wrong record type.
• Fix issues with expanding cond-expand expressions in libraries. Previously there would be issues with the expansion if the code needed to be within the context of a begin.
• Modified the reader to handle escaped intraline whitespace properly, per R7RS.
