Difference between otel/opentelemetry-collector-contrib  vs  otel/opentelemetry-collector

We are using OTEL libraries for generating Traces, logs & metrics. There are two sets of docker images - one under otel/opentelemetry-collector-contrib  and the other is-   otel/opentelemetry-collector.   What is the difference between these 2, what is recommended for what scenarios?

Is this component GAed already? if not what is the timeline for GA.
