v0.05

• Headers are now normalised for case, both request headers passed in and response headers received (thanks @mikz for the report)
• Response headers received with multiple matching field names are now presented as a table of values rather than concatenated, as this caused issues with Set-Cookie and potentially other cases. Note that when evaluating headers you must now consider the type could either be a table or a string. (Thanks to @ngo for the original pull request / suggestion).
