This issue is a work in progress.

Breaking

• 3.0.0 When requiring winston it will have no transports attached. Fixes this weird usage pattern
• 2.0.0 Separate daily-rotate-file.js from winston core.
• 2.x Update usage cycle.decycle to support Buffer instances and other edge cases. (could technically be a bug fix).
• 3.0.0 Any Transport will no longer emit the "logged" event.

Custom Formatters

• 3.0.0 Remove prettyPrint, json, depth in favor of customer Formatters
• 3.0.0 Remove rewriters in favor of customer Formatters
• 3.0.0 Remove filters in favor of customer Formatters
• 3.0.0 Drop logstash option in favor of custom Formatters

Any changes to levels & paramters

• 3.0.0 Only use meta-style JSON objects internally for all method signatures
• 2.0.0 Reorder default levels Revert "conform with RFC 5424" #349, or Reverse log level order for all levels so that syslog can be used again #290, or both

Tests for everything and anything

• 1.0.0 Tests for Http transport
• Exportable test suite for third-party transports.
• Better unit test coverage for common.log and other internal methods.

Miscellaneous

• 1.0.0 Drop pkginfo in favor of winston.version = require('../package.json').version;
• Cleaner API for making loggers: https://github.com/segmentio/winston-logger
• 2.0.0 Respect silent mode with a better implementation than Use log callback instead of event listeners. This prevents log handlers ... #327
• 3.0.0 All Transports should not default to any level. (see this comment)
• 2.0.0 Drop Webhook transport in favor of a single Http transport.
