## Solana validators face update deadline
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.
## Key takeaway

Solana mainnet-beta validators must install Agave 4.4.1 before epoch 1079 to avoid being forked from the network.
