Added automatic daily exchange rate synchronization from the NBS (National Bank of Serbia): rates for enabled currencies are fetched once per day (around 08:00) and applied to invoices, removing the need to enter them manually.
Added a per-currency “last updated” timestamp and source (auto/manual) shown in the exchange settings.
Added an “Auto-update rates daily” toggle so stores can switch to fully manual rate management, plus a “Sync rates now” button to fetch the latest rates on demand.
Manual rate edits are preserved for the day they are made; the next day’s automatic sync refreshes them.
Fixed misleading help text for the Receipt Header/Footer toggles: the actual header and footer text is entered per order (in the Fiscalization Information box on the order page), not in a separate dashboard.
Fixed the PURS payment type help text to list all supported types (Cash, Credit Card, Voucher, Check, Bank Transfer, Instant Payment, Other Non-Cash) instead of only five.
Duplicate “already being processed / already issued” fiscalization responses (which happen on accidental double-sends — e.g. a double click or a retry) are now logged and skipped silently with a neutral order note, instead of showing a confusing error. These are harmless system-level races and need no action.
1.3.5
Fixed advance invoice dateTimeOfIssue being sent without timezone information; the full ISO 8601 datetime with offset (e.g. +02:00) is now forwarded to the API so the backend parses the correct local time instead of interpreting it as UTC.
1.3.4
Fixed rounding mode incorrectly rounding line-item amounts to whole dinars instead of 2 decimal places; “Enable two decimal rounding” now correctly rounds to 2 decimals as labeled.
Applied rounding mode consistently to refund invoices (previously only applied to normal invoices).
1.3.3
Fixed items with zero total amount (including shipping) being incorrectly sent to the fiscalization API; they are now skipped before submission.
Fixed items with an empty name being sent to the API; they are now skipped alongside zero-amount items.
Fixed PIB auto-fill not working on order open: buyer ID code (type 10) and value are now correctly populated from the configured PIB meta key when the meta box renders.
1.3.2
Fixed unnecessary /auth/verify-api-token HTTP call on every WordPress page load; API key validation is now triggered only on demand (admin verify action, fiscal requests), reducing server load for all connected sites.
Fixed proforma-fiscalized order being incorrectly blocked from further fiscalization (“Order already fiscalized”): shared meta keys (_referent_document_number, _referent_document_dt) are no longer written for proforma invoices; invoiceExists() now uses per-type suffixed journal/URL as the primary signal.
1.3.1
Fixed duplicate order error (ERR_00603) on second fiscalization attempt caused by WordPress meta cache race condition.
Added explicit cache invalidation after order and refund meta save to ensure subsequent invoiceExists() checks always see updated markers.
Cache clearing now works on both HPOS (High-Performance Order Storage) and classic post-based WooCommerce systems.
Added info logging for meta persistence tracking to help diagnose fiscalization issues.
Enhanced invoiceExists() documentation to clarify cache behavior.
1.3.0
Fixed order list fiscalization column to show all actually created documents (proforma, all advance invoices, final invoice, and refund invoices).
Refund invoices are now visually highlighted in red in the orders list for faster identification.
Fixed false proforma display in orders list: proforma is now shown only when proforma URLs/PDF are present.
Fixed advance finalization request payload: finalize now sends payment entries in finalize format (amount=0 + advanceAmount) to avoid double-payment interpretation while preserving backend finalize logic.
Fixed finalize response parsing when backend returns wrapped payloads (finalReceipt), so created final receipts are correctly persisted to order meta.
Advance invoice datetime is now auto-filled and sent only for advance sale flow; other invoice types no longer send dateTimeOfIssue.
1.2.3
Added “Order number under receipt” setting (Receipt Header/Footer section): follow the shop setting from the Fiscomm platform (default), always show, or always hide the WooCommerce order number printed below fiscal receipts.
1.2.2
Fixed fatal error (“syntax error, unexpected ‘|’”) on PHP 7.4 that prevented the plugin from initializing — the plugin now runs on PHP 7.4 as declared.
Translated all remaining hardcoded admin strings; complete Serbian (Cyrillic) and English translations with updated language files.
Fixed plugin directory listing metadata (tags and contributors) not displaying on WordPress.org.
1.2.1
Added API key info card in plugin settings showing account details fetched from Fiscomm.
Added debug logging for API key verification request and response when debug logging is enabled.
Fixed QR code rendering in fiscalization confirmation emails (restored default renderer).
Fixed double-fiscalization of refunds when multiple refunds exist on the same order.
Fixed advance invoice finalization so a failed meta save cannot trigger a duplicate API call on retry.
Fixed buyer ID fields not being recognized when values contain leading/trailing whitespace.
Meta box fields on fiscalized orders are now editable so buyer identification can be added before processing a refund.
Added warning notice in the meta box when refund fiscalization is enabled but buyer ID is not set.
Updated WordPress compatibility to 6.8.
1.2.0
Removed third-party CDN loading for admin assets; now uses bundled local assets only.
Aligned plugin version metadata across plugin header, core constant, and readme stable tag.
