This is a Lotus patch release v1.28.2 for Node operators and Storage Providers.
For node operators, this patch release fixes an issue where excessive bandwidth usage (issue #12381) was caused by a routing loop in pubsub, where small "manifest" messages were cycling repeatedly around the network due to an ineffective routing loop prevention mechanism.
For node operators, this patch release is HIGHLY RECOMMENDED as it fixes an issue where excessive bandwidth usage (issue #12381) was caused by a routing loop in pubsub, where small "manifest" messages were cycling repeatedly around the network due to an ineffective routing loop prevention mechanism. The new f3 release also has a couple performance improvements around CPU usage. (If you are curious about the progress of F3 testing, follow the updates [here](https://github.com/filecoin-project/lotus/discussions/12287#discussioncomment-10343447)).
For storage providers, this patch release fixes pledge issues users have been encountering. This update addresses existing issues, including the too-small pledge in snap and the lack of DDO-awareness in PoRep Commit.
