05:52 AM Ruby Bug #22021 (Rejected): Array#delete_if may delete wrong object if array has been altered already

11:27 PM Ruby Feature #21619 (Open): logger: Context API

The logger gem is notoriously simple to use, but hard to extend.
One can only observe a few of the gems that added tags / json / logstash formatting support to see the same functionality reimplemented in "same but different" ways. For... chucke (Tiago Cardoso)
