```markdown
## [32.0.0]

### Changed

- **BREAKING:** Remove Sei, MegaETH, Avalanche, and ZKSync from list of default networks ([#8767](MetaMask/core#8767))
  - You will need to add them as network configurations first before switching to them.
- Bump `@metamask/controller-utils` from `^12.0.0` to `^12.1.0` ([#8774](MetaMask/core#8774))
```

## **Pre-merge author checklist**

<!-- mms-check: type=checklist required=true -->

<!--
Every checklist item must be consciously assessed before marking this PR
as
"Ready for review". A checked box means you deliberately considered that
responsibility, not that you literally performed every action listed.

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
checklist
semantics.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> The breaking default-network removal can affect users or flows that
relied on Avalanche, ZKSync, MegaETH, or Sei being preconfigured;
otherwise this is primarily a dependency and test-fixture alignment
change.
> 
> **Overview**
> Bumps **`@metamask/network-controller`** to **32.0.0** and
**`@metamask/controller-utils`** to **12.1.0** (including `package.json`
resolutions and `yarn.lock`).
> 
> That **breaking** network-controller release drops **Sei, MegaETH,
Avalanche, and ZKSync** from built-in default EVM networks, so fresh
installs no longer ship those chain configs unless users add them
manually.
> 
> Test fixtures are aligned: **`initial-background-state.json`** no
longer seeds MegaETH, ZKSync, or Avalanche mainnet entries, and
**`AddressSelector.test.tsx`** updates the expected EVM-only network
list to match.
