Anza urged Solana mainnet-beta validators to install Agave 4.4.1 before epoch 1079, warning nodes without the patch risk being forked out of the network.

Update tied to data size limit

The Solana development team tied the urgent release to a minimum loaded-data-size limit for loader-v3 ProgramData accounts under Agave 4.4.1.

Fork deadline set for Nov 6

Epoch 1079 was expected around 8:30 a.m. ET (13:30 UTC) Friday, Nov. 6, roughly 9:30 p.m. in Beijing. Unpatched validators face separation from the network through a fork.
