v0.2.6

cairn-miner v0.2.6

• Startup difficulty hint. The miner measures its real hashrate and sends
  mining.suggest_difficulty, so the pool starts you near your true difficulty
  instead of slowly ramping up after every start or reconnect. A safety cap
  plus the pool's own clamp mean a bad reading can never request an unsolvable
  difficulty. Opt out with --no-suggest-difficulty.
• Terminal dashboard. New cairn-dashboard.sh (Linux/HiveOS/macOS) and
  cairn-dashboard.bat/.ps1 (Windows) release assets: a read-only live view
  of hashrate, accepted/rejected/stale shares, difficulty, uptime, reconnects,
  and GPU temp/power. Multi-GPU rigs aggregate automatically. Requires the
  miner to run with --stats-port 3380 (HiveOS sets this automatically).
• Stale-share telemetry. Stale rejects (valid work that lost the tip race)
  are now counted separately from real rejects in /stats.
