v3.0.0

KNOWN ISSUES

• #319, #258 - TCP is no longer part of Listen, and there's currently no alternative except downgrading to Listen 2.x

API CHANGES

• TCP functionality removed (Listen.on, Adapter::TCP, Adapter::TCP::Broadcaster, etc.)
• Listener#start should be used instead of Listener#unpause
• Listener#directories is no longer available
• Listener#options is no longer available as public API

IMPROVEMENTS

• Major performance improvements (CPU), especially for Polling
• Celluloid is no longer required by Listen (which means: better performance, less dependencies, less threads used, less version conflicts, easier debugging, less potential issues/bugs)
• TCP is no longer part of Listen (which means: more maintainable codebase and possibility to create much better TCP implementation without the tradeoffs)

Development

• major codebase rewrite
• better logging by default
