Attention Klever Validators,

We are releasing a crucial hotfix for the Klever Blockchain. It is absolutely necessary that all validators apply this patch and upgrade their nodes to version `klever-go:v1.7.17-rc1` as soon as possible.

**⏳ DEADLINE:**  
This update must be completed BEFORE Monday, May 4, 2026, at 13:00:00 UTC (Epoch 5612).

**⚙ CONFIGURATION FILES:**  
You must download and apply the new configuration files available here:  
🔗 [https://backup.mainnet.klever.org/config.mainnet.108.tar.gz](https://backup.mainnet.klever.org/config.mainnet.108.tar.gz)

**⚠ IMPORTANT DISCLAIMER:**  
Make sure to update your config files prior to updating the node (there are changes with the fork update in enableEpochs.yaml).

This is a mandatory release candidate to ensure the continued stability and security of the network. Please prioritize this update.

**Our team is on standby and fully available to assist you or clarify any questions you might have during this process.** Please reach out in the chat if you need any help!

Thank you for your prompt action and dedication to the Klever network! 🌐
