Hedera canceled its planned v0.79 testnet upgrade on November 2, 2026, a move recorded at 20:02 UTC in the network’s official status history. The operator provided no technical explanation and no replacement deployment date, leaving infrastructure providers uncertain about the timeline for validating a major transition.
The canceled version is tied to Hedera’s shift from its legacy record-stream architecture to block streams, a new format designed to consolidate transaction records, consensus events and state changes. Hedera has said block streams are scheduled to become the canonical network output format during November 2026. The change introduces network-aggregated threshold signatures, allowing downstream systems to verify blocks without relying on separate record files and associated data streams.
Hedera advises exchanges, explorers and analytics providers running mirror nodes to deploy compatible mirror-node software version 0.163.0 or later before the transition. Systems using incompatible ingestion infrastructure could lose access to newly produced network records after the cutover, potentially disrupting balance reconciliation or transaction monitoring even while consensus processing continues.
According to the official status dashboard, the testnet remains on v0.78.0, while the mainnet is running v0.78.2 following a successful October 28 deployment. This means the cancellation concerns a planned testnet version change rather than a failure of the mainnet upgrade.
HBAR traded around $0.07014 on November 3, recovering modestly within a descending price channel. The first recovery threshold sits near $0.07123, with stronger supply between the 0.786 Fibonacci level at $0.07796 and the 100-day and 200-day moving averages around $0.07981 and $0.08080. Support is seen near the August swing low at $0.06355. The 14-day RSI was 32.29, indicating weak short-term momentum without a confirmed bullish divergence.
Hedera has not linked the cancellation to the block-stream migration or identified any specific software defect. The next meaningful update for operators would be a replacement testnet date, revised release notes, or updated block-stream validation instructions.
