 However, just like in Ethereum, this ordering is not guaranteed by the protocol, and some blocks might diverge from it. In particular, during periods of low mempool congestion, the sequencer will process transactions on a first-come-first-served basis, so some transactions might precede others with higher tip in the same block.
 
+## Reorgs and Finality 
+
+Starting from our [DarwinV2 upgrade](/technology/overview/scroll-upgrades#darwinv2-upgrade), the maximum reorg depth has been set to 17 blocks. Transaction ordering should be unchanged after this threshold, however the only absolute guarantee is for transactions to be finalized (proof submitted to L1).

 ## Future EIPs
 
 We keep a close eye on all emerging EIPs adopted by Ethereum and adopt them when suitable. If you’re interested in more specifics, reach out in [our community forum](https://community.scroll.io) or on the [Scroll Discord](https://discord.gg/scroll).

+## DarwinV2 Upgrade
+
+### Overview
+
+During internal testing, we identified that blocks may not always be compressible under certain conditions, which leads to unprovable chunks and batches.
+To fix this issue, a minor upgrade has been conducted so that uncompressed blobs will be enabled when this special case is detected.
+
+### Timeline
+
+As this is a security related patch, we bypassed the 7-day timelock mechanism.
+
+- **Scroll Sepolia**: August 28th, 2024
+- **Scroll Mainnet**: September 2nd, 2024
+
+### Compatibility
+
+#### Sequencer and Follower Nodes (l2geth)
+
+The new node version is `v5.7.0`. See the [release notes](https://github.com/scroll-tech/go-ethereum/releases/tag/scroll-v5.7.0) for more information.
+
+This upgrade does not change Scroll's state transition function, so it is backward compatible. However, the format of the batch data committed to Ethereum changes. As a result, nodes that enabled rollup verification (`--rollup.verify`) must upgrade to be able to follow the chain.
+
+#### Dapps and Indexers
+
+A change has been implemented to Scroll Mainnet to enhance sequencer throughput, which adjusted the maximum reorg depth to 17 blocks. Previously, the system performed thorough capacity checks within the signer thread to determine whether transactions exceed the circuit limit. While this ensures that all transactions within a block are compliant, it also requires additional CPU resources.
+We introduced a new circuit capacity checking scheme on Mainnet. The sequencer thread now will continue to perform capacity checks, but in a more approximate manner. In parallel, 16 worker threads will accurately verify the capacity of previous blocks. As a result, a reorg could occur with a maximum depth of 17 blocks, although the likelihood of this is low.
+
+For indexers, the `BatchHeader` version has been upgraded to 4. This is backward compatible (the only exception is for developers decoding the blob payload, which has changed slightly).

+
+Getting historical data on a smart contract can be frustrating when you’re building a dapp. [The Graph](https://thegraph.com/) provides an easy way to query smart contract data through APIs known as subgraphs. The Graph’s infrastructure relies on a decentralized network of indexers, enabling your dapp to become truly decentralized.
+
+The Graph supports both Scroll mainnet & testnet.
+
+#### Quick Start
+
+These subgraphs only take a few minutes to set up. To get started, follow these three steps:
+
+1. Initialize your subgraph project
+2. Deploy & Publish
+3. Query from your dapp
+
+Pricing: **All developers receive 100K free queries per month on the decentralized network**. After these free queries, you only pay based on usage at $4 for every 100K queries.
+
+Here’s a step by step walk through that includes screenshots:
