0.2.0

Our first major iteration on Relay has landed!

• User documentation is now hosted at https://docs.sentry.io/relay/.
• SSL support is now included by default. Just configure a TLS
  identity and
  you're set.
• Updated event processing: Events from older SDKs are now supported. Also,
  we've fixed some bugs along the line.
• Introduced full support for PII stripping. See PII
  Configuration for instructions.
• Configure with static project settings. Relay will skip querying project
  states from Sentry and use your provided values instead. See Project
  Configuration for a full guide.
• Relay now also acts as a proxy for certain API requests. This allows it to
  receive CSP reports and Minidump crash reports, among others. It also sets
  X-Forwarded-For and includes a Relay signature header.

Besides that, there are many technical changes, including:

• Major rewrite of the internals. Relay no longer requires a special endpoint
  for sending events to upstream Sentry and processes events individually with
  less delay than before.
• The executable will exit with a non-zero exit code on startup errors. This
  makes it easier to catch configuration errors.
• Removed libsodium as a production dependency, greatly simplifying
  requirements for the runtime environment.
• Greatly improved logging and metrics. Be careful with the DEBUG and TRACE
  levels, as they are very verbose now.
• Improved docker containers.
