1.0 Beta 1

Changes from pre 1.0

• Logger is now an interface, so future modifications to its struct vars will not be disruptive to users.
• Static Fields: set a key-value pair on a logger, to be included implicitly on every log line from then on.
• Json Formatting: optionally log in a json format. Default is still plain text.
• Typed LogLevel & LogLevelName

v0.5

This is the version before the new interface in v1.0.
