📋 What's Changed

• > [!IMPORTANT]
• > Required release for node operators running pruned nodes with `base-consensus`, optional release for archive nodes.
• The release updates `base-consensus` and `base-reth-node` to [0.9.1](https://github.com/base/base/releases/tag/v0.9.1)
• Full Changelog: https://github.com/base/node/compare/v0.16.0...v0.16.1

📋 What Changed

• > [!IMPORTANT]
• > Node operators must upgrade Base Mainet nodes to v0.16.0 by 28th May to support Base Azul. See [here](https://docs.base.org/base-chain/node-operators/base-v1-upgrade) for more information.
• As part of this upgrade, support for all clients except for `base-reth-node` and `base-consensus` have been dropped. See [here](https://docs.base.org/base-chain/node-operators/base-v1-upgrade#migrating-execution-layer) for migration details.
• This release updates base-consensus and base-reth-node to [0.9.0](https://github.com/base/base/releases/tag/v0.9.0) to support Base Azul.

📋 What's Changed

• > [!NOTE]
• >
• > This release updates `base/base` to [`0.8.0`](https://github.com/base/base/releases/tag/v0.7.5).
• This release updates `base-consensus` and `base-reth-node` to `0.8.0`. This improves execution and consensus peering reliability on Base Sepolia.

📋 What's Changed

• > [!NOTE]
• >

• Update Base to 0.7.3 in #1021.
• Full Changelog: https://github.com/base/node/compare/v0.15.1...v0.15.2

💥 Breaking Changes (same as `v0.15.0`)

• > [!IMPORTANT]
• The default consensus layer client is now `base-consensus`. Geth and Nethermind will no longer be supported starting with Base v1.
• Action required:
• Configure new `BASE_NODE` environment variables (see [example env files](https://github.com/base/node/blob/main/.env.mainnet))
• To temporarily opt out, set `USE_BASE_CONSENSUS=false`

📋 Changes

• Switch all entrypoints to use base-consensus authentication (#1001)
• Add legacy OP node flag (#1002)

📦 ❗ Mandatory update for Base Mainnet nodes to support the Jovian upgrade on December 2nd.

• Operators of Base Mainnet nodes must upgrade to this release _before_ December 2nd at UTC 16:00:01 UTC (unix timestamp 1764691201).

💥 ⚠️ Breaking Changes (same as `v0.14.1`)

• Similar to `v0.14.1` which was a mandatory upgrade for Base Sepolia node operators, this release also contains the following change and will be applied to mainnet node operators now as well.

🗑️ **`op-reth` Binary Removed, Consolidated into `base-reth-node`**

• The separate `op-reth` binary has been removed and is no longer available.
• All functionality previously provided by `op-reth` has been consolidated into the existing `base-reth-node` binary.
• Impact: If your deployment or scripts explicitly called the `op-reth` binary, you must update them to call `base-reth-node` instead.
• Parameters & Operation: The `base-reth-node` binary is designed to be identical in its command-line parameters and operational behavior to the removed `op-reth`. No parameter changes should be necessary other than the binary name itself.
• Reasoning: This consolidation allows us to more easily introduce and manage Base-specific features within a single, unified client binary.

📋 What's Changed

• chore: updated node-reth, reth by @github-actions[bot] in https://github.com/base/node/pull/661
• Full Changelog: https://github.com/base/node/compare/v0.14.2...v0.14.3

🐛 ❗ Critical bug fix for Base Sepolia Testnet nodes running Geth client

• This release contains a critical [fix to op-geth](https://github.com/ethereum-optimism/op-geth/releases/tag/v1.101603.5) in which historical block sync would halt after the Jovian fork.
• > [!Note]
• > This release is not required for Sepolia nodes running Reth, but is recommended for some performance improvements that come with the bump
• node-reth - v0.2.1: [diff](https://github.com/base/node-reth/compare/v0.2.0...v0.2.1)

🧪 ❗ Mandatory update for Base Sepolia Testnet nodes to support the Jovian upgrade on November 19th.

• Operators of Base Sepolia Testnet nodes must upgrade to this release _before_ November 19th at UTC 16:00:01 UTC (unix timestamp 1763568001).
• Also included is an important reth upgrade for stability and performance.
• > [!Important]
• > This release is highly recommended for Base Mainnet nodes
