To resolve issues that caused several nodes to lose sync with the network earlier this week, we released a new version of Stellar Core, and are scheduling a vote to upgrade the network to Protocol 16 on Saturday 4/10/21 at 1500 UTC.
For that to happen, we need some quick action and cooperation from anyone who runs Stellar infrastructure. If you run Stellar Core or Horizon, when you get this, please:
Upgrade to Stellar Core v16.0.0 ASAP: https://github.com/stellar/stellar-core/releases/tag/v16.0.0
Upgrade to Horizon, to Horizon v2.1.0 if you haven't already: https://github.com/stellar/go/releases/tag/horizon-v2.1.0
If you have not installed up-to-date software by the time the network upgrades, your node will lose sync until you do.
To make things easier for you, we also published a guide with links to relevant software and more detailed information about the upgrade process, which you can find here:
It has more specific instructions, and hopefully will answer common questions about the exact steps you need to take to prepare for the upgrade.
We appreciate everyone's support, cooperation, and patience as we worked to resolve these issues, and we are excited for this upgrade to restore service to anyone who is still having trouble. If you have questions, please feel free to reach out on the stellar.public Keybase #validators channel.
