# 0.1.0 Initial development
# 0.1.1 Added Tree view processing
# 0.1.2 Documentation review
# 0.2.0 Public release
# 0.2.1 Fixed bug where some videos cannot be embedded (played fullscreen automatically)
# 0.2.2 New python bindings conversion
#       Better exception error reporting
#       Better handling of invalid unicode data from source
# 0.2.3 Completed the exception error reporting improvements
