# Upgrading to v1.73.0
## Legacy Prometheus metric names have now been removed
Synapse v1.69.0 included the deprecation of legacy Prometheus metric names
and offered an option to disable them.
Synapse v1.71.0 disabled legacy Prometheus metric names by default.
This version, v1.73.0, removes those legacy Prometheus metric names entirely.
This also means that the `enable_legacy_metrics` configuration option has been
removed; it will no longer be possible to re-enable the legacy metric names.
If you use metrics and have not yet updated your Grafana dashboard(s),
Prometheus console(s) or alerting rule(s), please consider doing so when upgrading
to this version.
Note that the included Grafana dashboard was updated in v1.72.0 to correct some
metric names which were missed when legacy metrics were disabled by default.
See [v1.69.0: Deprecation of legacy Prometheus metric names](#deprecation-of-legacy-prometheus-metric-names)
for more context.
