  • Softens language around the modes of logging available #791 #785
  • Removes implicit appending of objects to message strings (see below) #795 #793

Implicit formatting removed #795

Previously, Pino emulated Bunyan's behavior when interpreting logs like:

  1. log.info('a message', { an: 'object'})
  2. log.info('a', 'silly', 'message')

The old behavior would result in 1 yielding "msg":"a message {\"an\":\"object\"}" and 2 yielding
"msg":"a silly message". As of this release, 1 will yield "msg":"a message" and 2 will yield "msg":"a".

To get the same results in Pino v6 as in previous releases actual format identifiers should be provided, e.g.:

  1. log.info('a message %j', { an: 'object' })
  2. log.info('a %s %s', 'silly', 'message')
