## 1.2.2 - 2026-09-04
-----
* Fix: `OrderRealRateApplier::apply()` now checks the excluded-currencies list — an excluded
currency is left completely untouched, including a rate that was cached before it got excluded.
* Fix: excluding a currency (or leaving its manual-rate field blank on submit) no longer silently
discards a previously-saved manual rate for a *different*, still-excluded currency.
* Fix: `saveManualRates()` now validates the cached reference rate (numeric, > 0) before writing
it to `Currency::conversion_rate`, matching the same guard already used elsewhere.
* Fix: `Db::insert()`/`Db::update()` now pass `$null_values = true` — an empty
`nbp_effective_date` was being stored as `''` instead of `NULL`, which fails under strict SQL
mode against the `DATE NULL` column and silently dropped the whole audit write.
* A failed cron sync (NBP unreachable, or no default currency configured) is now logged via
`PrestaShopLogger` and answers with a non-200 HTTP status, instead of a silent HTTP 200 —
previously nothing told the seller the cron had stopped working while orders kept getting an
increasingly stale cached rate.
* Replaced `PSHOWNBP_LAST_SYNC_SUMMARY` (a pre-rendered, already-translated string) with
`PSHOWNBP_LAST_SYNC_STATS` (raw numbers) — the "last sync" summary is now built in the current
viewer's admin language every time the page renders, instead of being frozen in whichever
language was active when the sync ran (an issue for cron-triggered syncs).
* Source strings for `trans()`/`{l s=}` are now English (translated PL/EN via the usual
`translations/*.php` files), matching the convention used by the module's other language files.
* `composer.json`'s `test` script no longer depends on PHPUnit (not present in the CI's
`--no-dev` build) — added `tests/run.php`, a dependency-free integration test that
actually runs in CI, covering `CurrencyRateUpdater::run()` and `OrderRealRateApplier::apply()`.
The PHPUnit suite stays available for local development via `composer run test:unit`
(equivalent to the existing `composer run phpunit`).
* Fixed a PHP 7.4-only typed property in a test file that failed to parse on the declared PHP 7.1
minimum.
* Fix: `Currency::resetStaticCache()`, used to make the new multistore sync loop below work
correctly, doesn't exist before PrestaShop 1.7.4.0 — calling it directly would fatal on the
1.7.0.0–1.7.3.x range this module declares support for. Now guarded with `method_exists()`.
* Multistore: a single cron hit now syncs every active shop, not just whichever shop's domain
received the request — `conversion_rate` and the reference-rate cache are per-shop, so one
shop's sync could otherwise never refresh another's. Excluded currencies and manual rates are
also independent per shop. The cron secret, the "auto update" switch and the NBP table choice
remain a single, installation-wide setting. `Order`-side behaviour is unaffected —
`OrderRealRateApplier::apply()` already runs in the placing order's own shop context, so it
always reads that shop's own reference rate. The "Update now" button is unchanged — it still
only syncs the shop currently selected in the admin, matching the rates table shown right below
it on the same page.

## 1.2.1 - 2026-09-04
-----
* Fix: `pshownbp_order_rate.nbp_effective_date` now stores the actual NBP-published date of the
applied rate table, instead of the date the sync happened to run on — the two could differ
after a weekend/holiday or when cron fires before NBP's daily publication.
* Checkout is now resilient to any unexpected error while recording the real-rate audit data
(e.g. a database hiccup) — the order is always saved normally; the error is only logged.
* The suggested crontab example moved from 8:30 to 13:00 — NBP typically publishes Table A by
12:15, so an earlier cron run was silently fetching the previous business day's rate.

## 1.2.0 - 2026-09-02
-----
* New: when an order is placed in a currency other than the shop's default one, the module
overwrites `Order::conversion_rate` with the real NBP reference rate (never the seller's manual
display rate) and records a full audit trail in the new `pshownbp_order_rate` table — checkout
vs. real rate, NBP table/date, and gross/net totals converted to the default currency, ready for
invoicing. The amount the customer paid never changes.
* Checkout never makes a live call to NBP — the real rate is read from the already-cached
reference rate kept fresh by "Update now"/cron, so a slow or unavailable NBP cannot affect
checkout time.
* Both cron delivery options (URL link and real crontab) now hit the exact same token-protected
front controller — no separate standalone script to keep in sync.
* Extracted all remaining inline CSS/JS from admin templates into dedicated files.
* In-admin manual (PL/EN) and README updated to document the new feature.

## 1.1.0 - 2026-08-19
-----
* New "Rate visible to customers" column on the main "Currency rates" table: type your own rate
(e.g. "4.5" for EUR, meaning 1 EUR = 4.5 PLN) and it's converted live, in the browser, to the
PrestaShop `conversion_rate` that actually applies on the storefront.
* The "Current rate" column now also shows the reciprocal (1/rate) next to the raw PrestaShop
value, so it reads in both directions at a glance.
* The automatic NBP sync (button and cron) keeps tracking the real market rate as a reference
even for currencies with a manual rate set — it just stops overwriting the applied rate for
those, until the manual rate is cleared.
* Extracted the last remaining inline `` blocks (main page, in-admin manual) into
dedicated CSS files — no CSS/JS left inline in templates.
* Added a module sanity test suite (`ModuleTest`) matching the other PrestaShow modules.

## 1.0.0 - 2026-08-18
-----
* init module
* Fetch currency exchange rates directly from the official NBP (Narodowy Bank Polski) API,
replacing PrestaShop's default EUR-anchored external feed.
* Manual "Update now" button plus optional cron/HTTP automation with a secret-token link.
* Per-currency exclusion list; default shop currency is never touched (its rate always stays 1).
* Status table showing every shop currency's current rate and update state.
* PL/EN in-admin manual and translations.
