@neolit123 many thanks for working on the annual report.
Just a few minor additions from my side

[fabriziopandini]

Should we add also in place and chained upgrades?

Suggested change

	[v1beta2](https://github.com/kubernetes-sigs/cluster-api/releases/tag/v1.11.0) of its API.
	[v1beta2](https://github.com/kubernetes-sigs/cluster-api/releases/tag/v1.11.0) of its API.
	- Cluster API added support for in [place updates](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20240807-in-place-updates.md).
	- Cluster API added support for [chained upgrades](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20250513-chained-and-efficient-upgrades-for-clusters-with-managed-topologies.md).

I would also add

• Cluster API added the PriorityQueue and the ReconcilerRateLimiting flags to improve performance at scale.

And somewhere down below

• Cluster API provider vSphere migrated all the E2E tests to community owned infrastructure sponsored by a Broadcom donation to CNCF.

i will leave only the top 3 items for CAPI, the other projects have 1 for now.
