Release notes — Community Alpha

The version, files and checksums on the download page come from the signed release metadata and are authoritative.

0.1.2

What's new

• Easier install on macOS. The disk image opens a window with TaktSignal and an Applications folder to drag it onto. Opened from the disk image anyway (or from a temporary place macOS uses for apps opened in Downloads), TaktSignal offers Move to Applications; a previous copy there goes to the Trash, and your data is kept.
• Which address signs in, and a forgotten password. The Control Center shows the administrator's sign-in address (also during setup when your data was kept from before) and can set a new password — only on the computer that runs TaktSignal. Everyone signed in with that account is signed out, and the audit log records it.
• About shows the installed and the running version when an update was installed from the Control Center, and the “Remove all data” step says that installed updates are removed with the data.
• Page changes show progress. A thin bar appears at the top when a page takes a moment to open.

Fixes

• Switching to a different ERPNext server or company now reads the new source completely. Before, the sync kept the previous server's reading position, so older documents on the new server were never read and every sync ended “partial”. TaktSignal now takes a backup (“Before ERPNext change”), removes the data read from the previous source (orders, work orders, stock, alerts — people, settings and the audit log stay), and reads everything again. New keys for the same server and company keep everything.
• Opening an alert right after snoozing another one could take several seconds. Pages now open promptly, and going Back after an action shows the updated list (a snoozed alert no longer lingers there).
• Integrations: the ERPNext card's details no longer run under the sync history on narrower windows; URL warnings appear as a notice.

For testers: MOCK_ERPNEXT_SCENARIO=healthy npm run mock:erpnext serves a small plant where nothing is wrong (green tab icon), dated from the moment the emulator starts.

Updating from 0.1.1: Control Center → Updates → Check for updates, or install the new download over the old app. A backup is taken first. No database changes in this release.

0.1.1

What's new

• Plant-health tab icon. The browser tab shows the TaktSignal mark with a coloured signal dome that follows the status the app already shows: red when there is an open critical alert, amber for open high or medium alerts, green when data is fresh and nothing above low is open, grey when nothing has been assessed yet, and a hollow amber dome when data is stale, degraded or a sync failed. It is a glance aid only — the text in the app stays authoritative. Tested in Chrome; Safari may keep the normal icon.
• Cleaner Control Center. A calmer layout with consistent spacing: the status, its three parts and the main actions sit in one card, the system check has its button in the header, ERPNext connection details are laid out as a list, and nothing touches anymore on narrow windows.

Fixes

• macOS “Not found” after replacing or deleting the app while it was running. Opening TaktSignal now stops an older copy still running in the background and starts the one you opened; a TaktSignal whose program files were deleted (for example one opened from the disk image or the Downloads folder) stops by itself, its database included. Your data is never touched.
• The Control Center system check no longer shows a false “public URL — APP_URL not set” warning.

Updating from 0.1.0: Control Center → Updates → Check for updates, or install the new download over the old app. A backup is taken first. No database changes in this release.

0.1.0

The first public Community Alpha build.

What TaktSignal is

Manufacturing Operational Intelligence for ERPNext. TaktSignal reads ERPNext operational data — sales orders, work orders, BOMs, stock, purchase orders and receipts — and helps teams see material, production, capacity and data-trust risks earlier, with the reason, the evidence, the estimated time at stake and a confidence label. It is decision support: not an ERP, not an MES, not a scheduler, and not production-proven.

Who this release is for

Manufacturers on ERPNext, operations and production managers, planners, ERPNext implementers and technically curious factory owners who can test against a staging or isolated copy of ERPNext and tell us what TaktSignal gets right and wrong. See Community Alpha limitations.

Platforms

ERPNext versions exercised

ERPNext 15 (v15.121.4) and ERPNext 16 (v16.36.0), with synthetic factory data. Older versions connect with a warning and are not validated.

Privacy model

• Read-only ERPNext connection with a dedicated Reader; setup refuses Administrator and write-capable accounts.
• An operational copy of your ERPNext data is stored locally, in TaktSignal's own database on your computer.
• No telemetry, no usage analytics, no crash reporting service, no advertising or tracking, no installation ID.
• No AI data sharing in the desktop build.
• Update checks only when you click, with no identifiers or factory data.
• Diagnostics only when you export them; no secrets or names inside.

Details: Privacy and your data.

Known limitations

• Windows is experimental: not published and not code-signed.
• In-app updates are tested on Linux; the first published macOS in-app update is 0.1.0 → 0.1.1.
• Tested in Chrome/Chromium; Safari, Firefox and Edge not yet.
• One computer, one person; no team sharing in the desktop build.
• Estimates and confidence are rule-based and not yet calibrated on enough real factories.
• No scheduled automatic backups (backups are taken before updates and restores, and on demand).

Full list: Community Alpha limitations.

Diagnostics and support

Control Center → Help & diagnostics → Export diagnostics, then follow Diagnostics and support. Never post API keys, passwords, backups or customer data.

Third-party software and source availability

This release bundles Node.js and PostgreSQL (with their own components). Licences and notices ship inside the app and are summarised in Licenses and notices, including where to obtain the source code of the LGPL-licensed GNU libiconv library bundled with PostgreSQL.

Not claimed

This release is not production-ready, not code-signed on Windows or Linux, not certified or externally audited, and has not been validated in enough real factories to claim time savings. Community Alpha exists to find out.
