Mandatory update

The latest version is already coded, built and available here: https://github.com/heliumchain/helium/releases
I recommend that you update as soon as possible because all the forks will die with the new version.

I have created this guide for when someone is in a chain different from the main one, but for this case it's better that, after updating your wallet, you do step 7 directly:

If you have any problem, please tell us in #support (at Slack)

To update the nodes quickly follow this guide: https://www.heliumlabs.org/v1.0/docs/masternodewallet-update-guide
