2.0.5 (2026-07-16)
===============================================================================
MCDC Stock — version 2.0.5 (2026-07-16)

Short summary:
• Fix: creating an in-house solution (`/stock/createnewsol/`) no longer raises `KeyError: 'lot_no'`. `Inventory.create` defaults missing `lot_no`, and audit logging records the lot numbers actually assigned (stock number when empty).
• `Solutions.create` now passes an empty `lot_no` explicitly so solution receipts follow the same path.
• Migration `0027_alter_procurementneed_status`: aligns procurement need status choice labels with the tracker (“Needs ordering”, “Items ordered”, “Items received”).
• Regression test: `test_solution_create_lot_no`.

2.0.4 (2026-07-09)
===============================================================================
MCDC Stock — version 2.0.4 (2026-07-09)

Short summary:
• Inventory reports and stock reports now include Supplier Catalogue Number (`reagent.cat_no`) on item export rows (URS-XX1).
• Barcode batch lookup (Reports): paste or upload stock numbers; view all matches in one table within laboratory scope (URS-XX2).
• Batch export: selectable columns; download PDF, Excel, or CSV with barcode, reagent, supplier, catalogue #, lot, dates, storage, and status (URS-XX3).
• Reagent Usage Log (PDF): printable log from the batch lookup results for experiment documentation, with optional experiment reference (URS-XX4).

2.0.3 (2026-07-09)
===============================================================================
MCDC Stock — version 2.0.3 (2026-07-09)

Short summary:
• Procurement tracker (Reports): single spreadsheet-style grid replaces the separate planner form and planner queue screens; edit all fields inline with dropdowns, date pickers, and text cells.
• Row colours: white = needs ordering, amber = ordered, green = received; status is derived automatically from requisition, PO, dates, and received quantity.
• Auto-populate: low-stock reagents are added to the tracker on open (and via “Refresh low-stock rows”); filters and column sorting included.
• New planner fields: procurement route (R12 / Manual PO / Other), person ordering, date ordered, date received, quantity received; Manual PO no longer requires an R12 requisition.
• Audited cell saves via `/stock/reports/procurement/save/`; CSV export updated; legacy planner queue / add / edit URLs redirect to the tracker.
• Note: database migration `0026_procurement_need_tracker_fields` is required.

-------------------------------------------------------------------------------

2.0.2 (2026-06-16)
===============================================================================
MCDC Stock — version 2.0.2 (2026-06-16)

Short summary:
• Experiment report added (Reports menu and catalog): select an experiment and export stock as PDF or XLSX (attributed at open or used in usage records).
• Procurement planner queue (Edit Data): separate list, add, and edit screens for planner lines; status workflow Needs ordering → Items ordered (R12 requisition) → Items received (PO reference).
• Procurement control: edit and remove PO lines and goods receipt lines on dedicated screens; receipt linking updates received quantities and PO fulfilment status; removal blocked when inventory is linked.

-------------------------------------------------------------------------------

2.0.1 (2026-06-01)
===============================================================================
MCDC Stock — version 2.0.1 (2026-06-01)

Short summary:
• Add controlled storage-location adjustments: `storage_before` / `storage_after` fields and `storage` adjustment kind.
• UI and form support for changing storage location from the item adjustment form.
• Safety: validation to require one change at a time and improved help text.
• Backend: `apply_stock_adjustment` handles storage updates and audit logging; adjustment log now selects related storage objects.
• Search: add `cat_no` (catalogue number) search support.
• Note: a database migration is required to add the new `storage_before` / `storage_after` columns.
