Anza Set Nov. 6 Deadline for Solana Validators to Install Agave 4.4.1

Anza set Nov. 6 as the deadline for Solana validators to install Agave 4.4.1, warning that nodes using older software risked being separated from the network’s canonical chain at epoch 1079.

The epoch was expected to begin at about 8:30 a.m. ET Friday (13:30 UTC), the timing attached to Anza’s notice. The warning centered on compatibility between validator clients and the network during the transition. Anza framed the software change as a way to maintain network continuity through the epoch shift.

Anza identified Agave 4.4.1 as the version validators needed to install before the epoch change. Nodes left on incompatible software risked ending up on a different fork instead of the canonical chain.

A fork in this context would mean affected validators were no longer following the same chain as the rest of the network. The notice placed the risk at the epoch transition, with Nov. 6 serving as the upgrade cutoff.
