scroll-v5.2.0

Overview

This release embeds the Scroll Sepolia testnet fork height for Bernoulli, scheduled to go live at block 3747132 (within a few hours after Mon Apr 15 02:30 am UTC). The Bernoulli hard fork upgrade contains the following changes:

• Enable SHA-256 precompile.
• Use EIP-4844 blobs for Data Availability (not part of l2geth).

Additionally, this release contains new features and important robustness improvements. This release aims to fix a long-standing bug #592 that would lead to database corruption in rare cases when the L1 endpoint would become temporarily unavailable. When this happens, the best recourse is to re-sync the node. To avoid this, it is recommended to upgrade to this release.

For nodes running on Scroll Sepolia, upgrading is mandatory. On Scroll mainnet, upgrading is optional but recommended.

Compatibility

This release introduces a hard fork upgrade on the Scroll Sepolia testnet. Nodes that are not upgraded will be unable to follow the testnet after the hard fork block.

To follow the Bernoulli upgrade on Scroll Sepolia, simply upgrade your node and run it with the --scroll-sepolia flag. If you do not use this flag but provide a custom genesis file instead, then you must add "bernoulliBlock": 3747132 to the fork list in genesis.json.

Please refer to this document for further notes on compatibility.

Notable changes
