Download SysManager 1.136.121

[1.136.121] - 2026-11-06
The Dashboard's temperature cards and usage bars now change only when the figure they show does, rather than on every reading.
Fixed
- The Dashboard built every temperature card again each time it read the sensors, every 2 seconds, although a
temperature that moved by less than a degree shows the same figure. Each time, a screen reader was told the list
of cards had changed. Now a card changes only when its figure, its name or its colour does, and it is updated
where it stands rather than built again. Since the Dashboard's redesign in 1.17.0.
- The processor, memory and GPU bars took each reading unrounded, three times a second, so a bar was laid out
again on every reading although the whole number shown above it stayed the same. They take that whole number
now, rounded the way the figure is. Since 1.17.0.
Changed
- The Dashboard's live readings and Resource History's sampler take their snapshot on the thread they already run
on, rather than handing it to a second thread and waiting for it.
Verify the download
Get-FileHash .\SysManager-v1.136.121.exe -Algorithm SHA256
Expected SHA256: B33FAE318077DAB8F6CE0F43D80E055E845E786F60EE720F5B6320D1B29707AD
This build is not code-signed, so Windows will warn on first launch. That is
expected for a small independent app: see what the warning says and what to
click.
Code signing is planned through the SignPath Foundation,
which provides free certificates to open-source projects, with signing performed by
SignPath.io. Until then, the SHA256 above and the build
attestation below are what establish that a download is the genuine build.
Code signing policy
This release is not code-signed. The team roles, release-approval process and
privacy policy required by the SignPath Foundation programme
are documented in advance under Code signing
policy. That
documentation is a prerequisite for applying, not evidence of a certificate. The
attribution line naming SignPath as the signing provider will appear here once a
certificate is actually issued.
This program will not transfer any information to other networked systems unless
specifically requested by the user or the person installing or operating it. Two checks
run on their own when SysManager starts: the version check against the GitHub Releases
API, at most once a day, and the Dashboard's app-updates alert, which asks winget. The
About tab can switch off either. Everything else that uses the network runs only when you
use it. Full
privacy policy.
Verify where this binary came from
This exe was built by GitHub Actions from this public source, and the build is
recorded in the Sigstore public transparency log. With the
GitHub CLI:
gh attestation verify .\SysManager-v1.136.121.exe --repo laurentiu021/SystemManager
That proves which commit and workflow produced this exact binary, something the
SHA256 file cannot show, since it is published alongside the exe it describes.
Each release also ships SysManager-v1.136.121.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
