```

✓ Descriptive subject✓ Provides detailed explanatory context
The short version

What changed, and why it matters

This commit simply refreshes Electrum's built-in list of Bitcoin blockchain checkpoints. Checkpoints are known-good block hashes that help the wallet verify it is following the real chain. The update adds newer checkpoints for mainnet, signet, testnet, and testnet4. There is no code change and no security vulnerability introduced or fixed here.

Recommended action

No security action needed. Treat as routine data maintenance; verify checkpoint hashes against a trusted source if performing due diligence.

Security signals we found

No strong security signals were identified.
