+
+Welcome to the April 2024 Edge Release Roundup post, where we dive into the
+most recent edge releases to help keep everyone up to date on the latest and
+greatest! This month, we're covering the releases from `edge-24.4.5` back to
+`edge-24.3.3` -- there's a lot here so we'll get right into it.
+
+## How to Give Feedback
+
+Remember, edge releases are a snapshot of our current development work on
+`main`; by definition, they always have the most recent features but they may
+have incomplete features, features that end up getting rolled back later, or
+(gasp!) even bugs. If you're running edge releases, it's _very_ important that
+you send us feedback on how things are going for you!
+
+We would be delighted to hear how these releases work out for you! You can
+open [a GitHub issue](https://github.com/linkerd/linkerd2/issues/) or
+[discussion](https://github.com/linkerd/linkerd2/discussions/), join us on
+[Slack](https://slack.linkerd.io), or visit the [Buoyant Linkerd
+Forum](https://linkerd.buoyant.io) -- all are great ways to reach us.
+
+## Community Contributions
+
+We couldn't do what we do without the Linkerd community, and this batch of
+releases is definitely no exception. Huge thanks to [Adarsh Jaiswal], [Akshay
+Dongaonkar], [Cemal Y. Dalar], [Firas Medini], [Grigoriy Mikhalkin],
+[hanghuge], [Ilia Lazebnik], [Hirotaka Tagawa], and [occupyhabit] for their
+contributions! You'll find more information about all of these contributions
+in the release-by-release details below.

+
+## Breaking Changes
+
+There are no breaking changes in these releases. However, we have two specific
+recommendations:
+
+- We recommend `edge-24.4.4` instead of `edge-24.4.3` due to a metrics-naming
+  regression in `edge-24.4.3`.
+- We recommend `edge-24.3.4` instead of `edge-24.3.3` since `edge-24.3.4`
+  contains an important fix for Gateway API users.
+
+## The Releases
+
+Recent edge releases have been mostly focused on upcoming IPv6 support and
+some significant bugfixes. Of course, each edge release has _many_ dependency
+updates; we won't list them all here, but you can find them in the release
+notes for each release.
+
+_(Last Roundup we did these in chronological order, but we're switching this
+time to reverse chronological order, starting with the most recent.)_
+
+### [`edge-24.4.5`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.4.5) (April 25, 2024)
+
+This edge release continues work on upcoming IPv6 support, and allows setting
+`revisionHistoryLimit` when installing with Helm to specify how many
+ReplicaSets to keep around for rollback purposes (thanks, [Ilia Lazebnik]!)
+
+It also allows setting certain HTTP/2 server parameters using environment
+variables (see [proxy PR 2924] if you think you need this!).
+
+[proxy PR 2924]: https://github.com/linkerd/linkerd2-proxy/pull/2924
+
+### [`edge-24.4.4`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.4.4) (April 18, 2024)
+
+This edge release fixes a metrics naming regression introduced in the previous
+release, restoring the `outbound_http_...` metrics to their correct names
+instead of duplicating `http`.
+
+### [`edge-24.4.3`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.4.3) (April 18, 2024)
+
+_We recommend `edge-24.4.4` instead of this release due to a metrics-naming regression in `edge-24.4.3`._
+
+This edge release fixes the second of two issues where where
+`policy.linkerd.io` HTTPRoutes could be endlessly patched even when they
+weren't changing ([issue 12310]).
+
+[issue 12310]: https://github.com/linkerd/linkerd2/issues/12310
+
+### [`edge-24.4.2`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.4.2) (April 11, 2024)
+
+This edge release fixes an issue where the service mirror controller would
+panic if it encountered an error listing mirror services while fixing its list
+of endpoints, and continues work on upcoming IPv6 support. It also allows
+correctly setting policy controller resources via Helm, instead of just
+defaulting them to the same as the destination controller (thanks, [Grigoriy
+Mikhalkin]!), allows relabeling metrics to customize how high-cardinality
+metrics get handled (thanks, [Cemal Y. Dalar]!), and does a little cleanup of
+documentation in the code (thanks, [hanghuge]!).
+
+### [`edge-24.4.1`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.4.1) (April 4, 2024)
+
+This edge release continues work on upcoming IPv6 support.
+
+### [`edge-24.3.5`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.3.5) (March 28, 2024)
+
+This edge release adds metrics to the queue of HTTPRoute status updates and
+makes the ExternalWorkload resource's status as a subresource, as it always
+should have been. It also corrects the scope of the proxy-injector,
+tap-injector, and jaeger-injector mutating webhook rules to Namespaced (thanks
+[Firas Medini]!), and cleans up some documentation in the code (thanks
+[occupyhabit]!).
+
+### [`edge-24.3.4`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.3.4) (March 22, 2024)
+
+This edge release fixes the first of two issues where `policy.linkerd.io`
+HTTPRoutes could be endlessly patched even when they weren't changing ([issue
+12104]), and another where the destination controller could generate large
+numbers of unnecessary endpoint updates when a Server changed. It also adds
+default values to generated docs for the `proxy-*-connect-timeout` annotations
+(thanks [Akshay Dongaonkar]!), fixes excessive logging in the injector webhook
+([issue 12186], thanks [Adarsh Jaiswal]!), and cleans up an unneeded error
+message from the destination controller (thanks [Hirotaka Tagawa]!).
+
+Finally, this edge release fixes an issue that could mistakenly turn off local
+traffic policy when an endpoint is removed ([issue 12311]), adds a timeout to
+HTTPRoute status patches, continues work on upcoming IPv6 support, and stops
+unnecessarily checking about injecting the `kube-system` namespace when
+running in HA mode.
+
+[issue 12186]: https://github.com/linkerd/linkerd2/issues/12186
+[issue 12104]: https://github.com/linkerd/linkerd2/issues/12104
+[issue 12311]: https://github.com/linkerd/linkerd2/issues/12311
+
+### [`edge-24.3.3`](https://github.com/linkerd/linkerd2/releases/tag/edge-24.3.3) (March 14, 2024)
+
+_We recommend `edge-24.3.4` instead of this release since `edge-24.3.4`
+contains an important fix._
+
+This edge release allows configuring the pod disruption budget via Helm
+([issue 11321], thanks [Cemal Y. Dalar]!).
