## 2.43.0-rc.0 / 2023-03-09
We are working on some performance improvements in Prometheus, which are
available behind the go tag `stringlabels` (therefore are not shipped in the
default binaries). It uses a data structure for labels that uses a single string
to hold all the label/values, resulting in a smaller heap size and some speedups
in most cases. We would like to encourage users who are interested in these
improvements to help us measure the gains on their production architecture.
Building Prometheus from the source with the `stringlabels` go tag and providing
feedback on its effectiveness in their specific use cases would be incredibly
helpful to us. #10991
