+## 4.2.0 - 2023-01-16
+
+### Functional Shanghai Support
+
+This release fully supports all EIPs included in the [Shanghai](https://github.com/ethereum/execution-specs/blob/master/network-upgrades/mainnet-upgrades/shanghai.md) feature hardfork scheduled for early 2023. Note that a `timestamp` to trigger the `Shanghai` fork update is only added for the `sepolia` testnet and not yet for `goerli` or `mainnet`.
+
+You can instantiate a Shanghai-enabled Common instance for your transactions with:
+
+```typescript
+import { Common, Chain, Hardfork } from '@ethereumjs/common'
+
+const common = new Common({ chain: Chain.Mainnet, hardfork: Hardfork.Shanghai })
+```
+
+### EIP-4844 Shard Blob Transactions Support (experimental)
+
+This release supports an experimental version of the blob transaction type introduced with [EIP-4844](https://eips.ethereum.org/EIPS/eip-4844) as being specified in the [01d3209](https://github.com/ethereum/EIPs/commit/01d320998d1d53d95f347b5f43feaf606f230703) EIP version from February 8, 2023 and deployed along `eip4844-devnet-4` (January 2023).
+
+#### Initialization
+
+To create blocks which include blob transactions you have to active EIP-4844 in the associated `@ethereumjs/common` library:
+
+```typescript
+import { Common, Chain, Hardfork } from '@ethereumjs/common'
+
+const common = new Common({ chain: Chain.Mainnet, hardfork: Hardfork.Shanghai, eips: [4844] })
+```
+
+**Note:** Working with blob transactions needs a manual KZG library installation and global initialization, see [KZG Setup](https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/tx/README.md#kzg-setup) for instructions.
+
+### Other Changes
+
+- Handle hardfork defaults consistently, PR [#2467](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2467)
+- New `generateWithdrawalsSSZRoot()` method, PR [#2488](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2488)
+- Allow genesis to be post merge, PR [#2530](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2530)

 ### Consensus Types
 
 The block library supports the creation as well as consensus format validation of PoW `ethash` and PoA `clique` blocks (so e.g. do specific `extraData` checks on Clique/PoA blocks).

+
+The blockchain library now allows for blob transactions to be validated and included in a chain where EIP-4844 activated either by hardfork or standalone EIP (see latest tx library release for additional details).
+
+### Block Interface getBlock() Signature Fix
+
+Always a bit tricky, but we felt that we needed to do this. We had a misalignment of our blockchain implementation of the `Blockchain.getBlock()` method and the definition of the associated interface:
+
+- Blockchain class: `async getBlock(blockId: Buffer | number | bigint): Promise<Block>`
+- Blockchain interface: `getBlock(blockId: Buffer | number | bigint): Promise<Block | null>`
+
+So the Blockchain interface was - falsely - claiming that there would be the possibility of a `null` value returned in the case of a block not being found while the actual implementation was throwing an error in such a case.
+
+We now fixed this by removing the `null` from the interface return values - see PR [#2524](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2524), after exploring the other way around as well (and the reverting), see PR [#2516](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2516).
+
+While this might lead to breaking code constallations on the TypeScript level if this `null` value is picked up we felt this is the right thing to do since this divergence would otherwise continue to "trick" people into assuming and dealing with `null` values for non-existing-block assumptions in their code and continue to produce eventual bugs (we actually fell over this ourselves).
+
+A bit on the verge of breaking vs. bug fixing, sorry if you are eventually affected, but we just can't do a single breaking release update for a fix on that level.
+
+### Other Changes
+
+- Timestamp-related `Blockchain.createGenesisBlock()` fix, PR [#2529](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2529)
+- Allow genesis to be post merge, PR [#2530](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2530)
+- Add extra validations for assuming nil bodies in `getBlock()`, PR [#2534](https://github.com/ethereumjs/ethereumjs-monorepo/pull/2534)
