Changelog for logging-effect-1.1.1

1.1.1

withBatchedHandler no longer prints empty log messages. Previously, if you ran a program that didn't log but used withBatchedHandler (or anything that used that), an empty log message would be output. Thanks to @codedmart for fixing this.

Breaking changes:

MonadLog no longer has logMessage as a function. It now has logMessageFree which takes a free monoid of log messages. If you were just using logging-effect then this won't affect you, as logMessage still exists with the same signature outside the type class.
MonadLog now comes with a law that states that logging is a monoid homomorphism. This essentially means that you have to treat all log messages uniformly.
Pass-through instances for all "stock" monad transformers have been added (all of transformers, CatchT from exceptions and FreeT/FT from free).
WithSeverity now has instances of Traversable and Foldable
WithTimestamp now has instances of Eq, Ord, Read and Show.

Additions:

A set of convenience functions have been added for quickly logging with severity. The combinators are: logDebug, logInfo, logNotice, logWarning, logError, logCritical, logAlert and logEmergency.
mapLogMessage got a companion function mapLogMessageM that works with monadic tranformations.
