What shipped. When. Why.

We release on Tuesdays. Patches are SemVer; behaviour changes get the bench's attention via a banner in the console. Subscribe to /changelog.xml for the feed.

Tightened the bench safety policy file.

  • FIXResolved a race where a missed compliance event could be reported after the auto-shutdown ramp.
  • FIXKeysight DSOX1204G — corrected timebase rounding on 200 µs/div.
  • IMPPolicy file now supports per-rail temperature gates with custom hysteresis.
  • IMPReport manifest hashes are now SHA-256 across the board (was SHA-1 for legacy sessions).

FLOW learns to share the bench.

  • NEWMulti-instrument choreography — SMU + FG + Scope orchestrated in a single agent loop.
  • NEWDrivers for Siglent SDS1104X and Rigol DG4202.
  • NEWLive waveform reasoning — anomalies (clipping, ringing, drift) flagged in the agent stream with the matching trace segment.
  • IMPConsole: KPI strip is now driven at instrument cadence rather than browser cadence.
  • IMPProtocols can now declare per-step abort predicates with units.

Signed reports, by default.

  • NEWEvery session emits a signed manifest. `lf replay` now guarantees byte-identical re-runs.
  • NEWReport templates: PDF, HTML, Markdown, LaTeX. Brand-aware headers.
  • IMPOpenTelemetry exporter — traces, metrics, logs, with hardware events attached.
  • IMPDriver matrix expanded to 38 instruments across 10 vendors.

Labflow 4 — agent-first console.

  • NEWRebuilt console around the agent stream — bench rail, work surface, agent column.
  • NEWflow-l model: longer context, better multi-instrument plans, sharper observations.
  • NEWBench safety policy file replaces ad-hoc per-instrument clamps.
  • NEWOperator override — single keystroke suspends the agent and returns control.
  • IMPDiscovery now spans GPIB, USBTMC, LAN (mDNS) and Serial in one pass.

PSRR & step-response protocols shipped in-library.

  • NEWPre-flight protocols: PSRR sweep, step response, jitter histogram, 24-hour burn-in.
  • NEWDriver: NI USB-6363 with streamed acquisition.
  • IMPConsole: dark titlebar with session path breadcrumb (bay › session › protocol).
  • FIXTektronix MSO64 — robust handling of incomplete acquisitions on early triggers.

First public beta.

  • NEWPublic beta — free for a single bench.
  • NEWDrivers for Keithley 2400 / 2450, Tektronix MSO64, Rigol DG1022Z, R&S NGE100.
  • NEWNatural-language → SCPI compilation with bench-aware validation.
  • IMPAuto-discovery on GPIB, USBTMC and LAN.
