Releases

Network upgrades, in order

v444August 2026Pure Price Emissions

Subnet emission returns to pure price EMA through the gate. The release also completes the typed EVM surface, makes multisigs first-class btcli wallets, adds human-readable Ledger orders, and lands a broad reliability pass.

v441July 2026Root Reborn

Nearly half of all TAO sits on root. This release turns its dividend stream into validator-curated baskets — live network numbers, how the fund works, btcli commands, breaking changes, and the migration of legacy claimable state.

v440July 2026The Emission Gate

Subnet emission now has to beat a market-set demand bar: price-proportional above it, a smooth collapse below it. Idle slots stop earning, and the cost of building on Bittensor falls toward the registration transaction.

v439July 2026Conviction for Contracts

EVM access to stake locks and miner conviction, rolled lock views, bounded conviction queries, locked-alpha transfer policy, and subnet owner-cut auto-lock controls.

v438July 2026Interfaces & Reliability

Bounded EVM staking views, Ledger-friendly limit-order signatures, exact mechanism emission splits, predictable epoch counters, repaired testnet warp sync, and a more recoverable release train.

v437July 2026Collateral & Key Lineage

Miner registration collateral, on-chain hotkey and coldkey swap lineage, bonded key-swap hardening, one-call stake transfer to a new coldkey and hotkey, air-gapped Polkadot Vault signing, and fully benchmarked extrinsic weights.

v431July 2026The Monorepo Release

Conviction-based subnet ownership, price-driven emissions, the bittensor v11 SDK with a Rust core, Ledger and browser-extension signing, and a verifiable upgrade pipeline — the chain, SDK, CLI, and docs developed and released together.
