3.0.0 (2018-06-01)

BREAKING CHANGES

• Predefined levels are no longer accessible at logger.predefinedLevels property.
  Instead they should be required from log4/levels

• For simplicity and to avoid compliance issues,
  only predefined levels are allowed (it's no
  longer possible to create custom named levels)

• enable() and disable() methods no logger return own logger.
  Instead they return plain object with restore function, that allows to restore to previous state

  get

  namespace

  Instead it should be required from log4/emitter

• getAllLevels method has been renamed to
  getAllInitializedLevels

• hasLevel method has been renamed to
  isLevelInitialized

• hasNs method has been renamed to
  isNamespaceInitialized

• New setupVisibility accepts:

  • levelThreshold - on its basis it's decided logs for which levels are
    enabled by default

  • debugNamespaceToken - List of namespaces to be exposed for
    levels below threshold

• getLevel method was removed. Use direct property names:
  log.error instead of log.getLevel("error")

• getAllNs method has been renamed to
  getAllInitializedNamespaces
