 ## EVM Precompiles
 
-The `SHA2-256` (address `0x2`), `RIPEMD-160` (address `0x3`), and `blake2f` (address `0x9`) precompiles are currently not supported. Calls to these precompiled contracts will revert. We plan to enable these three precompiles in a future hard fork.
+The `RIPEMD-160` (address `0x3`) and `blake2f` (address `0x9`) precompiles are currently not supported. The `SHA2-256` (address `0x2`) is currently supported on Scroll Sepolia, but will soon be supported on Scroll Mainnet. Calls to unsupported precompiled contracts will revert. We plan to enable these precompiles in future hard forks.
 
 The `modexp` precompile is supported but only supports inputs of size less than or equal to 32 bytes (i.e. `u256`).

 ### Finding the latest version
 
-We recommend using the latest release at https://github.com/scroll-tech/go-ethereum/releases. For Scroll Mainnet, the required version is `scroll-v5.0.0` or higher. If you'd like to keep up with new node releases, go to https://github.com/scroll-tech/go-ethereum, click on **Watch**, **Custom**, and make sure that **Releases** is selected.

+## Apr 2024 Bernoulli Upgrade
+
+### Overview
+
+This upgrade features a significant reduction in transaction costs by introducing support for EIP-4844 data blobs and supporting the SHA2-256 precompile. 
+
+### Timeline
+
+- **Scroll Sepolia**
+	- Network Upgrade: April 24th, 2024
+- **Scroll Mainnet**
+	- TBD
+
+### Technical Details
+
+#### Contract changes
+
+The contract changes for this upgrade are in [this PR](https://github.com/scroll-tech/scroll/pull/1179).
+
+As well as the audit fixes listed here [TODO]
+
+#### Node changes
+
+The new node version is v5.2.0. See [here](https://github.com/scroll-tech/go-ethereum/releases/tag/scroll-v5.2.0) for the changelog.
+
+#### Prover changes
+
+[TODO]
+
+#### Audits
+
+- OpenZeppelin [TODO]
+- TrailofBits [TODO]
+
+### Compatibility
+
+#### Sequencer and follower nodes (l2geth)
+
+This upgrade is a hard fork as it introduces the new blob data type and the SHA2-256 precompiled contract. Operators running an `l2geth` node are required to upgrade before the hard fork block. See the [node releases](https://github.com/scroll-tech/go-ethereum/releases) for more information.
+
+#### Indexers and Bridges
+
+This upgrade changes the format that Scroll uses to publish data to Ethereum. Projects that rely on this data should carefully review [the new data format](https://docs.scroll.io/en/technology/chain/rollup/#codec), and check whether their decoders need to be adjusted. A summary of the new format:
+
+- The format of [`BlockContext`](https://github.com/scroll-tech/scroll/blob/5362e28f744093495c1c09a6b68fc96a3264278b/common/types/encoding/codecv1/codecv1.go#L125) will not change.
+- `Chunks` will [no longer include](https://github.com/scroll-tech/scroll/blob/5362e28f744093495c1c09a6b68fc96a3264278b/common/types/encoding/codecv1/codecv1.go#L162) the L2 transaction data. This will instead be [stored in a blob](https://github.com/scroll-tech/scroll/blob/5362e28f744093495c1c09a6b68fc96a3264278b/common/types/encoding/codecv1/codecv1.go#L284) attached to the `commitBatch` transaction.
+- `BatchHeader` now contains one new field, [`BlobVersionedHash`](https://github.com/scroll-tech/scroll/blob/5362e28f744093495c1c09a6b68fc96a3264278b/common/types/encoding/codecv1/codecv1.go#L405). 
+
+#### Provers
+
+This upgrade involves a breaking change in zkevm-circuits. Operators running a prover node are required to upgrade.
