I've just pushed poster 0.6.0 to the cheeseshop. Thanks again to everybody who sent in bug reports, and for letting me know how you're using poster! It's really great to hear from users. poster 0.6.0 fixes a few problems with 0.5, most notably:

• Documentation updates to clarify some common use cases.
• Added a poster.version attribute. Thanks to JP!
• Fix for unicode filenames. Thanks to Zed Shaw.
• Handle StringIO file objects. Thanks to Christophe Combelles.

poster 0.6.0 can be downloaded from the cheeseshop, or from my website. Documentation can be found at https://atlee.ca/software/poster/
