Allow full control over the output format (merge requests #2, #3). To do
so, a type Renderer has been added which can be configured via
setRenderer. The setting netstring has been removed, instead the
complete renderer can be requested via renderer.
A setting setReadEnvironment has been added which allows one to ignore
process environment variables (see merge request #7).
0.14.1
Maintenance release to enable compatibility with GHC 8.4.
0.14.0
setFormat now expects a Maybe DateFormat to allow for not having a date
format at all.
0.13.0
Change DateFormat representation to UnixTime -> ByteString. This
is mainly to allow clients complete control over date and time formatting.
