What's new

Release notes for each sprint, most recent first.

Sprint 19 — MVP test round 2 fixes Latest

EC numbering — Engineering Changes now use their own number sequence (EC-YYYY-NNNN), separate from ECR and ECO numbers.

Responsible Engineer — New optional field on Change Requests (both create and detail). Dropdown filters by Engineering department. EC list resolves engineer names instead of showing IDs.

EC detail restructure — “BoM Upload” tab renamed to “Engineering Change Details”. Attachments moved from a separate tab into the bottom of this tab. Status stepper added below the breadcrumb.

BOM comparison — Source (item type) and Effective From columns added. Delete buttons removed (comparison is now read-only). CSV download includes revision and effective date columns. QTY column mapping fixed for snapshot imports.

CR governance — Return to Draft button on submitted ECRs. Timeline deduplication for approve/reject events. Info tooltips on Classification and Severity column headers.

Action lists — Assignee dropdown grouped by department (department users first, then Others). Action templates page has a department filter. Priority and department updates no longer flash/reset.

Sprint 18 — MVP polish & UI consistency

Access control & governance — Coordinator-only checks on ECR status transitions (Start Review, Submit Decision). CCB process can now be toggled on/off in Settings, hiding the CCB Review step from the workflow when disabled.

Filter system overhaul — All list pages (Change Requests, Engineering Changes, ECOs, ERP Items) now use multi-select filter dropdowns with checkboxes, Select All, Clear Selection, and badge pills matching the table. Archived records toggle on CR, EC, and ECO pages.

Preliminary action improvements — Priority column added to action lists with inline-editable badge dropdown. Department badges are clickable to change directly in the table. Add Action and AI Suggest buttons side by side. Due date column on EC/ECO action lists.

Dynamic department colours — Department colours are now stored in tenant settings and applied consistently across the entire application. New departments auto-receive a colour from a 12-colour palette. Departments in use cannot be deleted (usage check shows what is attached).

Table & pagination — Tables with 50+ rows show a pagination bar fixed at the bottom of the viewport with sticky headers. Default sort indicator shown on page load.

ECR detail polish — Title displayed next to ECR number, horizontal pill badge layout for classification/severity/trigger/change type, collapsible attachments section, Safety badge as red pill, info tooltips on Classification and Severity fields.

Sprint 17 — Phase-in calculator integration

Phase-in at the EC level — engineers can now run phase-in calculations directly on an Engineering Change, before an ECO exists. Select a strategy, click Suggest Phase-in Dates, and review per-item suggestions with conflict flags and action previews. Accept individually or all at once.

Phase-in suggestion engine on the EC Affected Items tab — strategy dropdown (RunDown, NewOnly, Stop, Proactive), suggest button, accept/reject per item
Action preview per item — rule-based action drafts shown inline (read-only preview, final actions generated on ECO release)
