Every fix and update to the NexusPool core, with its date. The current stable version is highlighted.
v0.6.26.38
Stratum V2 extended-channel mining now works reliably for miners connecting through a translator proxy. Previously, when the connecting software declared a very high hashrate, as some setups do by default, the pool opened the connection at a difficulty far too hard for a small rig, so nearly every share was briefly rejected as "difficulty too low" until the pool slowly caught up. The pool now opens every V2 connection at a safe low difficulty and raises it as it measures the real rate, and it recovers automatically if a connection ever ends up stuck too hard, so a small rig behind a translator mines with normal acceptance from the first share. No effect on how a won block is found or paid out.
v0.6.26.37
Stratum V2 standard-channel mining now works end to end. A modern V2 miner opening a standard channel receives its first job as a future job that the pool activates with the block's previous-hash, the exact handshake spec-compliant V2 clients expect, so the miner establishes its chain tip and starts mining, instead of the channel going quiet right after it connects. The pool now also answers a channel it cannot open with a clear error instead of staying silent, and never sends a previous-hash update for a job the miner did not receive. Extended-channel mining, and everything about how a won block is found or paid out, are unchanged.
v0.6.26.36
Stratum V2 fairness, continued from .35: valid work is now credited across a difficulty increase even in the brief moment between the pool raising a rig's difficulty and the rig taking it up. The pool now waits until a rig has actually adopted the higher difficulty before holding it to that difficulty, so a share the rig mined at the difficulty it still had is credited instead of briefly rejected, and a rig on a modern V2 connection sees its accepted-share rate stay steady through a difficulty change. No effect on how a won block is found or paid out.
v0.6.26.35
Stratum V2 interoperability and fairness. Modern V2 mining firmware can now verify the pool's identity from a single standard connection string, published in the documented V2 URL format so any spec-compliant client can pin it. And valid work is credited more reliably: shares a rig mined at the difficulty it was assigned are no longer briefly rejected when the pool raises that rig's difficulty. The difficulty each job is judged against is now frozen the moment the job is sent, matching the Stratum V1 path exactly. No effect on how a won block is found or paid out.
v0.6.26.34
Performance & scale: the dashboard and public API stay fast and responsive under heavy load, even as the pool's history grows large. Heavy pool-wide statistics (the hashrate windows) are now computed continuously in the background instead of on every request, the most-used database queries are indexed, frequently-requested data is briefly cached, and telemetry writes are batched. Validated with a sustained 2-hour load test at campaign scale (100% availability, no memory growth). No effect on mining, share accounting, or won blocks.
v0.6.26.33
New: a public Terms of Use page and a legal disclaimer in the site footer. NexusPool is stated plainly for what it is: free, non-custodial software, a Bitcoin communication protocol, not a product, service, or investment; SweetHash never holds your funds or keys; block rewards are paid on-chain directly to your address; and there is no guarantee of finding a block (solo mining is a lottery). Informational only; no effect on mining, share accounting, or won blocks.
