We are in the process of upgrading the BetaNet relays to v2.0.4. You can expect them to be upgraded by around 8pm (EST), Nov. 15. Differing from previous BetaNet releases, this release does contain a protocol change, so you will need to upgrade.
The full list of PRs associated with this release to BetaNet are listed at https://github.com/algorand/go-algorand/commits/rel/beta.
To update your current version of BetaNet to 2.0.4, run the following goal command:
./update.sh -c beta -i -d <betanet-data-directory> -n
If you haven’t already done so, we also advise setting up a CRON job to automatically update your algorand networks. If you haven’t done this for BetaNet, you can follow the instructions here: https://developer.algorand.org/docs/configure-auto-update
