+# v1.14.0 Release Note
+
+## Summary
+**v1.14.0 has a hardfork, which will be activated at block height 29,275,561
+(ETA is around 04/03/2024 00:52:05 AM UTC) on IoTeX mainnet.**
+
+All nodes **must** upgrade to this release, otherwise the node runs the risk of
+not being able to sync with the IoTeX blockchain after other nodes have upgraded.
+
+**Note:**
+There's no change to the mainnet config.yaml and genesis.yaml. You only need to
+restart your node with the new v1.14.0 image.
+
+Version 1.14.0 has enabled two significant new features: IIP-24 Raise Block Gas
+Limit to 50M and IIP-25 delegate endorsement.
+
+With IIP-24, the block gas limit has now been raised to 50M, greatly enhancing
+the processing capabilities of the IoTeX blockchain while ensuring its stability.
+This enhancement allows the blockchain to achieve a maximum of 1000 TPS
+(transactions per second), significantly speeding up transaction processing on
+the blockchain, especially during times of network congestion.
+
+The activation of IIP-25 introduces a novel governance model: it allows big
+stakeholder to create a bucket for endorsing delegate. This would make delegate
+management more flexible and encourage more enthusiastic projects to become IoTeX
+delegates and actively participate in the IoTeX network operation, thereby
+fostering the inclusivity of the IoTeX network and enhancing the diversity of the
+ecosystem.
+
+## Other Improvements
+v1.14.0 release also comes with a couple of improvements:
+1. Improved performance for DB snapshot operation
+2. Enabled web3js format for CandidateActivate and CandidateEndorsement
+3. Make action pick order deterministic
+4. Added more unit tests and end-to-end tests
+
+## Upgrade Priority
+v1.14.0 comes with a hardfork, so all nodes **must** upgrade in order to keep
+syncing with the IoTeX blockchain
+
+| Node type  | Action       |
+| ---------- | ------------ |
+| Delegate   | Must upgrade |
+| Fullnode   | Must upgrade |
