 1. What work did the SIG do this year that should be highlighted?

-<!--
-   Some example items that might be worth highlighting:
-   - Major KEP advancement
-   - Important initiatives that aren't tracked via KEPs
-   - Paying down significant tech debt
  - Governance and leadership changes
-->
+
+    - Casey Davenport (**[@caseydavenport](https://github.com/caseydavenport)**)
+      and Dan Williams (**[@dcbw](https://github.com/dcbw)**) stepped
+      down as Chairs, Shane Utt (**[@shaneutt](https://github.com/shaneutt)**) and
+      Mike Zappa (**[@mikezappa87](https://github.com/mikezappa87)**) became new
+      Chairs (joining Tim Hockin (**[@thockin](https://github.com/thockin)**), who
+      remained a Chair)
+
+    - Dan Winship (**[@danwinship](https://github.com/danwinship)**) and
+      Antonio Ojea (**[@aojea](https://github.com/aojea)**) became SIG Network's
+      first Tech Leads.
+
+  - Gateway API
+
+    The [Gateway API reached v1.0 and is now GA!]. Specifically, the
+    `Gateway`, `GatewayClass`, and `HTTPRoute` APIs are now v1, with
+    several other APIs also being added or updated in the experimental
+    channel. Also, the old validation webhook is now deprecated in
+    favor of CEL-based validation. See [the v1.0.0 release notes] for
+    full details.

+
+  - NetworkPolicy API Working Group
+
+    The Network Policy API WG mainly focused on the maintenance and
+    new feature development regarding our two major APIs,
+    AdminNetworkPolicy and BaselineAdminNetworkPolicy. This also
+    included a few talks at KubeCon NA 2023 in Chicago:
+
+      - [Network Policy API: Intro and Project Update]
+      - [AdminNetworkPolicy: A New Kubernetes-Native API for Comprehensive Cluster-Wide Network Security]
+
+    Additionally, major features such as [Egress Traffic Control],
+    [FQDN Selectors] and [Network Tenancy] all made great progress
+    during the year and we are excited to deliver them here in 2024.
+
+    On top of the APIs and Features, we introduced the
+    [Policy-Assistant] tool which allows users to have a better overview
+    of how all of the native Kubernetes APIs interact on real
+    clusters.

 2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?

+The Network Policy API group is always looking for more people to get
+involved. Whether that's trying out our APIs, updating docs, or
+helping our with NPEP design, we are hugely appreciative of all help.
+Please checkout [our website](https://network-policy-api.sigs.k8s.io/)
+for even more information.
+
+Historically, SIG Network as a whole has not been great at onboarding
+new contributors, but contributions are definitely welcome. (There has
+recently been a flurry of [new-contributor effort around the new
+nftables kube-proxy backend].)
+
+We also continue to have problems with Windows networking, where most
+of the people who regularly attend SIG Network meetings know very
+little about Windows (and most of the people who regularly attend SIG
+Windows meetings know very little about networking). If you know a lot
+about Windows container networking (or want to learn) and want to get
+involved, it would be greatly appreciated.

 3. Did you have community-wide updates in 2023 (e.g. KubeCon talks)?

-<!--
-  Examples include links to email, slides, or recordings.
-->
+We gave a SIG update at KubeCon EU: [SIG Network: Intro and Updates].
