 - During a network upgrade, log migration progress every 2 seconds so they are more helpful and informative. The `LOTUS_MIGRATE_PROGRESS_LOG_SECONDS` environment variable can be used to change this if needed. ([filecoin-project/lotus#12732](https://github.com/filecoin-project/lotus/pull/12732))
 - Add F3GetCertificate & F3GetLatestCertificate to the gateway. ([filecoin-project/lotus#12778](https://github.com/filecoin-project/lotus/pull/12778))
 - Add Magik's bootstrap node. ([filecoin-project/lotus#12792](https://github.com/filecoin-project/lotus/pull/12792))
+- Lotus now reports the network name as a tag in most metrics. Some untagged metrics will be completed in a follow-up at a later date. ([filecoin-project/lotus#12733](https://github.com/filecoin-project/lotus/pull/12733))
