Full Changelog: v2.1.0...v2.2.0

v2.1.0 New severity formatters

• 015d605 Add %{severity} and %s formatters

%{severity} outputs the long form (INFO, WARNING, etc) and %s outputs a single letter (I, W, etc).

With this release the %L / %l formatter is deprecated. Going forward the term "severity" will be used.

v2.0.1 Bug fix release

• 841b402 Set default log level to INFO, not TRACE
• 749993c Don't delegate to parent log if there is none

Simpler API with default log

No longer necessary to pass a log to log-info, log-debug, et al. Default log is in *log* and may be set or dynamically bound.

Bug fix for elapsed-milliseconds

A crash when the %{millis} format control is used has been fixed.

Initial tagged release

Starting to tag releases so that the package manager can reference them.
