SysManager 1.76.12

[1.76.12] - 2026-09-04

Two pieces of background work the app was doing for no reason. Nothing looks different; the app just asks
Windows fewer questions and does less writing while you use it.

Fixed

• Reading the system's vitals no longer makes other parts of the app wait. The Landing tab reads CPU and
  memory three times a second. That read held a lock for the whole trip out to Windows and back, so anything
  else asking for the same information at that moment queued behind it, even though it had no interest in the
  part being locked. The lock now covers only the details that are read once per session.
• Trimming the history files no longer rebuilds every line it keeps. Both the resource-usage and bandwidth
  histories drop entries older than the retention window. Doing so rebuilt every surviving line from scratch,
  and the result was thrown away whenever nothing needed dropping — which is almost every time, since a trim
  only has work to do once entries age out. Surviving lines are now kept exactly as they were read.

Verify the download

Get-FileHash .\SysManager-v1.76.12.exe -Algorithm SHA256

Expected SHA256: C57CAEB6B127C48D248E7DC8012416F1FAC5FD6F8BDD9A09BB7E508349A65ABB

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. 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-v1.76.12.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-v1.76.12.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
