## bunyan 1.3.1 (not yet released)
(nothing yet)
- [issue #164] Ensure a top-level `level` given in `bunyan.createLogger`
is *used* for given `streams`. For example, ensure that the following
results in the stream having a DEBUG level:
var log = bunyan.createLogger({
name: 'foo',
level: 'debug',
streams: [
{
path: '/var/tmp/foo.log'
}
]
});
This was broken in the 1.0.1 release. Between that release and 1.3.0
the "/var/tmp/foo.log" stream would be at the INFO level (Bunyan's
default level).
## bunyan 1.3.0
