NetSentinel v2.1.22
Security & Verification
Every release is signed and checksummed. Verify before running.
| Check | Result |
|---|---|
| VirusTotal scan | aHR0cHM6Ly9n… |
| SHA256 checksums | SHA256SUMS.txt |
Verify the SHA256 checksum (Windows):
$expected = (Get-Content SHA256SUMS.txt | Select-String 'NetSentinel-Setup').ToString().Split(' ')[0]
$actual = (Get-FileHash 'NetSentinel-Setup-2.1.22.exe' -Algorithm SHA256).Hash.ToLower()
if ($expected -eq $actual) { '✅ OK' } else { '❌ MISMATCH' }Verify the cosign signature (Windows installer):
cosign verify-blob \
--bundle NetSentinel-Setup-2.1.22.exe.bundle \
--certificate-identity-regexp "https://github.com/ossianericson/netsentinel/.*" \

v2.1.22 (current)
Added
- Service unreachable? NetSentinel now diagnoses why in the background and tells you — filtered by a firewall/VPN/ISP, or a real outage — right in the notification
- Opt-in automatic speed tests with a tray alert when your download speed drops sharply against your own history
- Morning Briefing now summarizes overnight service outages and speed drops, when those features are enabled
- Recurring "quiet hours" — scheduled speed tests and their alerts stay silent overnight without pausing background monitoring
Changed
- Navigation colours extracted to 8 named semantic tokens; Arctic Clean sidebar is now white chrome; Midnight Pro card background elevated — all nav hover/active/focus states use theme-aware tokens instead of hardcoded
rgba()values - Badge, info-box, banner, and canvas colours moved into per-theme dicts across both themes
Fixed
- Dark-theme
BORDER(rgba(255,255,255,0.08)) no longer crashes matplotlib or renders black inQColor; newCHART_SPINEplain-hex alias routes all non-QSS border colours safely - Monitor resume and alert banners confined to the content area (no longer bleed over the nav rail)
- Arctic Clean active nav text raised to WCAG AA+ contrast (~6.9:1)
