SysManager 1.131.15のダウンロード

[1.131.15] - 2026-10-28
The command line's error output is valid JSON again when the error message itself contains a line
break or a tab, and four background timers no longer measure time against the wall clock.
Fixed
- The command line's --json error output was built by hand for one fault path, escaping only
backslashes and quotes. A message containing a carriage return, line feed or tab produced a
document a JSON parser rejects, on the exact branch whose own comment says it keeps the output
machine-readable. It now goes through the same serializer as every other --json error.
- Four places measured an interval by subtracting DateTime values instead of a monotonic clock: the
notification area's 4-hour cooldowns (a clock set back kept them silent for longer than intended, not
shorter), Process Manager's CPU-percent sampling window, Ping's per-sample timestamp, and Bandwidth
Monitor's 5-second history throttle, which lost up to an hour of saved history during the repeated
autumn daylight-saving hour because the subtraction went negative. All four now use a monotonic
timestamp for the interval itself.
Changed
- EtaCalculator's one remaining plain-object lock target is now the dedicated Lock type the rest
of the app's locks already use, and an automated check keeps it that way. (#2855)

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-v1.131.15.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-v1.131.15.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
