logstash-mixin-deprecation_logger_support 1.0.0-java

This gem is meant to be a dependency of any Logstash plugin that wishes to use the Deprecation Logger introduced in 7.6 while maintaining backward-compatibility with earlier Logstashes. When used on older Logstash versions, it provides an implementation of the deprecation logger that forwards deprecation messages to the normal logger at WARN-level with a `DEPRECATED` prefix.
