2.0.0

BREAKING CHANGES:

• The object passed to the async callback is now a JSON-compatible hash, not a Raven::Event. This fixes many bugs with backend job processors like DelayedJob. [@nateberkopec, #547]
• Several deprecated accessors have been removed [@nateberkopec, #543]
• You can no longer pass an object which cannot be called to should_capture [@nateberkopec, #542]

ENHANCEMENTS:

• Rack::Timeout exceptions are now fingerprinted by URL, making them more useful [@nateberkopec, #538]
• Added an HTTP header processor by default. We now scrub Authorization headers correctly. You can use config.sanitize_http_headers to add a list of HTTP headers you don't want sent to Sentry (e.g. ["Via", "Referer", "User-Agent", "Server", "From"]) [@nateberkopec]

FIXES:

• User/Event IP addresses are now set more accurately. This will fix many issues with local proxy setups (nginx, etc). [@nateberkopec, #546]
• We now generate a real UUID in the correct format for Event IDs [@nateberkopec, #549]
• If async sending fails, we retry with sync sending. [@nateberkopec, #548]
• Changed truncation approach - event messages and HTTP bodies now limited to the same amount of characters they're limited to at the Sentry server [@nateberkopec, #536]

OTHER:

• Codebase cleaned up with Rubocop [@nateberkopec, #544]
