Hi,
we just released new versions of the Tor Metrics Library, metrics-lib 2.5.0, and Tor Metrics Website, metrics-web 1.2.0.
The primary reason for these new releases is that libraries contained in the tarball match the ones needed to build current master.
Downloads are available at:
https://dist.torproject.org/metrics-lib/2.5.0/
https://dist.torproject.org/metrics-web/1.2.0/
Please direct comments and questions to the metrics-team mailing list:

All the best, Karsten -- on behalf of the Metrics Team.
