 ## [Unreleased]
 
+## [Zebra 6.2.3](https://github.com/ZcashFoundation/zebra/releases/tag/v6.2.3) - 2026-07-27
+
+This is an optional release with network hardenings for operators that experience issues with their nodes peer set connectivity or otherwise want to be proactive about avoiding such issues.
+
+This release helps keep Zebra's peer set healthy. While syncing, outbound connection slots are
+no longer occupied by peers that can't serve blocks, dropped outbound connections are proactively
+replaced, and `getaddr` responses share more of the address book so peers can find more of the
+network. Zebra also no longer disconnects peers during expected long gaps between blocks, or
+penalizes them for briefly disagreeing about the NU6.3 activation.

 ### Fixed
 
 - Outbound peer slots no longer fill up with peers that advertise no services, which could stall
   a fresh sync at genesis when most reachable listeners are non-serving. While syncing, Zebra
   now requires the `NODE_NETWORK` service from outbound peers; at or near the network tip it
   accepts non-serving peers (like pruned nodes) again

 - Zebra now sends up to half of its address book in response to a `getaddr` request, up from
   a quarter, so peers can find more of the network from each response. The maximum address
   book size is now pinned at 5000 instead of being derived from the response fraction
