Changelog

Uploading files to test runs and units used to require three API calls (initialize, PUT, finalize) plus a fourth to link the attachment. Now it's one call across all five SDK clients.

• Added runs.attachments.upload() and units.attachments.upload() helpers that handle the full upload flow in a single call across Python, C#, Rust, C++, and MATLAB
• Added units.attachments.delete() to remove attachments from units by ID
• Added runs.attachments.download() and units.attachments.download() to download attachments to local files

from tofupilot.v2 import TofuPilot

client = TofuPilot()

# Upload a file to a run
client.runs.attachments.upload(id=run.id, file="data/test-report.pdf")

# Upload a file to a unit
client.units.attachments.upload(serial_number="SN-0001", file="data/calibration.pdf")

# Download
client.runs.attachments.download(attachment, dest="local-report.pdf")

# Delete (units only)
client.units.attachments.delete(serial_number="SN-0001", ids=[attachment_id])

Timestamps with timezone offsets like +02:00 or +05:30 now work across all API endpoints. You no longer need to convert to UTC before uploading.

• Accepted timezone offsets on all datetime input fields: run timestamps, phase and log timestamps, and date filters on runs, units, batches, and procedures
• Responses still return UTC (Z suffix), no changes needed on the read side

from datetime import datetime, timezone, timedelta

# UTC (always worked)
client.runs.create(
    started_at=datetime.now(timezone.utc),
    ended_at=datetime.now(timezone.utc),
    ...
)

# Local timezone (now works too)
cet = timezone(timedelta(hours=2))
client.runs.create(
    started_at=datetime.now(cet),
    ended_at=datetime.now(cet),
    ...
)

Trigger automated actions when test events occur. Connect your test data to the tools your team already uses, without writing glue code.

• Added visual workflow editor with drag-and-drop nodes, branching (if/else, switch), filters, and versioning
• Added integrations for Odoo, Linear, InvenTree, Discord, Slack, email, and generic HTTP
• Added execution history with per-step status, error details, and flow visualization

Control charts were limited to one measurement at a time. You can now overlay multiple compatible measurements on a single chart to spot correlations and trends across your process.

• Added multi-measurement selection with Shift-click on the measurement overview, with compatibility checks (same type and units)
• Added phase filter in sidebar showing data point counts per phase when multiple measurements are selected
• Added compatibility tooltips showing which criteria match or mismatch when selecting measurements
• Limits and Cpk tab now hide automatically when selected measurements have different spec limits

You can now upload runs, manage parts, and query test data directly from MATLAB -- no middleware, no CSV exports.

• Upload runs with measurements, limits, and attachments in a few lines of MATLAB code
• Query and filter units, batches, and procedures from your test scripts
• Automatic retries on transient errors so uploads don't fail mid-production
• Ships as a .mltbx toolbox -- install once, available across all your projects

Teams running C++ test scripts can now upload runs, measurements, and attachments to TofuPilot directly from their codebase.

• Added full V2 API coverage for runs, units, parts, batches, stations, procedures, and attachments
• Added builder-pattern API for creating runs with phases, measurements, validators, and logs
• Added one-call file upload and download helpers for test reports and artifacts

Process control gets smarter defaults, better filtering, and a new PDF export for sharing charts outside TofuPilot.

• Added A4 landscape PDF export for charts with title and "Exported by" attribution
• Added validators column and measurement outcome filter to the process control measurement table
• Added default 30-day date filter on runs, logs, and API calls pages for faster initial load
• Fixed invisible connecting lines between points on control charts
• Fixed missing procedure, phase, unit, and run outcome on measurement detail page

The phase/measurement table on the run sheet page got a full redesign. Measurements now open in a dedicated sidebar panel with charts, validators, and aggregations.

• Restyled phase/measurement table with consistent row spacing, sticky header, and unified column grid matching other tables across the app
• Added measurement and phase sidebar panels with full detail views: metadata, validators table, aggregations table, JSON code block, and multi-dimensional charts with reference lines
• Migrated multi-dimensional charts to recharts with legend, axis labels, toggleable aggregation reference lines, and a fullscreen dialog
• Added outcome filters (fail, error, skip), search, sort, and relative/duration time toggle to the section header

The Insights page is now Process Control, rebuilt from scratch.

• Added interactive control charts with spec limits, control limits, histograms, and capability indices (Cp, Cpk, Pp, Ppk) for numeric, string, and boolean measurements
• Added sidebar filters for outcome, value range, retries, and all standard run filters, with a measurement selector sorted by failures, fail rate, or Cpk
• Added measurement table with checkbox selection to drill down into matching runs or units in one click
• Faster loads. Charts and capability indices now compute server-side.

Upgraded our server runtime to the latest stable LTS version for better performance, security patches, and long-term support.

• Upgraded server runtime from Node.js 20 to 22 across all deployments
• Updated self-hosted Docker image to the new runtime
