Upgrade to Knots 29.4.3 before block 979,920 (expected around this time tomorrow)
Miners: Upgrade before activation. If you're still on an older version after block 979,920, your blocks are likely to be rejected under the tighter CBM consensus rules.
Pruned nodes: Upgrade before activation. If you upgrade after that height, you may need to resync the entire chain history from scratch.
Full Archival nodes: Upgrading isn't required, but you'll miss the new spam filters included in this release.
quoting53% of reachable nodes already updated their software that includes the new 180-days rolling CBM and the new spam filters.
