v0.34.1

Primary changes:

• Forcing a new release as there were some timeouts to bintray for 0.34.0. The
  artifacts for 0.34.0 appear to be ok, but just to be sure it is recommended to
  avoid it and use 0.34.1 instead.
• Add prefix to distinguish timer and distribution summary percentile counters.

v0.34.0

⚠️ There were some timeouts with the release build during the maven sync phase (#261). Please use 0.34.1 instead.

• Catch throwable in digest reporting thread to ensure logs are available to user.
• Added helpers for accessing registered meters as a Stream.
• Fix naming of SpectatorMetricCollector to match convention in aws sdk.
• Servo registry will not report timers and counters unless there is activity. Before it would report if the counter or timer was accessed even if there was no activity.

0.30.0

Primary changes:

Update generic types for Registry.gauge methods so a cast isn't needed:

Queue<Item> queue = ...

// This will now work:
registry.gauge("gauge", queue, Queue::size)

// Instead of:
registry.gauge("gauge", queue, q -> ((Queue) q).size())

Adds configuration block to allow for common tags to be added to reported digests:

spectator.tdigest.tags = [
  {
    key = "app"
    value = ${APP_NAME}
  }
]

Others:

• Fixes name mapping for metrics3 registry so tags are separated with a ..
• Added additional compatibility test case using class compiled with a previous version. Catches a number of binary compatibility issues missed with the existing checkCompatibility task.
