Exchange rate providers are now pluggable via the module Registry. The four built-in drivers (currency_converter, currency_freak, currency_layer, open_exchange_rate) move from a static config array into App\\Providers\\DriverRegistryProvider, which calls Registry::registerExchangeRateDriver() for each during app boot with metadata the frontend needs: label (i18n key), website (help-text URL), and config_fields (schema for driver-specific driver_config JSON).
The Currency Converter's server-type selector and dedicated URL field — previously hardcoded in ExchangeRateProviderModal.vue — are now just another config_fields entry with a visible_when rule that shows the URL input only when type=DEDICATED. Any module that wants to ship a custom driver gets the same treatment for free: declare config_fields in the registration, and the host app's modal renders them automatically.
ExchangeRateDriverFactory::make() falls back to Registry::driverMeta() when a name isn't in the local built-in map, and availableDrivers() merges both sources. ConfigController handles the exchange_rate_drivers key specially by mapping Registry::allDrivers('exchange_rate') to enriched option objects, so the config-file route still works for every other key. The static exchange_rate_drivers + currency_converter_servers arrays in config/invoiceshelf.php are deleted.
Unit tests cover the new Registry::register/flushDrivers, the factory merging built-ins with Registry-contributed drivers, and the factory rejecting unknown names. A feature test exercises the end-to-end /api/v1/config?key=exchange_rate_drivers response shape.
NOTE: this commit depends on invoiceshelf/modules package commit e44d951 which adds the Registry driver API. The package needs to be released and pinned in composer.json before a fresh composer install on this commit will work.
Mail DEFAULT_DRIVER changes from smtp to sendmail; DRIVER_ORDER is reshuffled so sendmail is the head of the list on fresh installs. This matches what most self-hosted installs already have working out of the box — SMTP requires provider credentials the typical user doesn't have set up yet. The mail config description is rewritten to drop the 'Laravel' framework reference and to explicitly tell unsure users to leave it on sendmail.
SiteApi::get() now catches GuzzleException (the broader interface) and returns null on network failure instead of bubbling the exception object — callers were treating a non-array return as 'marketplace unavailable' anyway, so null is the correct shape.
main.ts exposes the Vue runtime on window.__invoiceshelf_vue so module JS (compiled against the host's Vue install) can call createApp / defineComponent without re-bundling Vue. invoiceshelf.css adds Tailwind source globs for Modules/**/*.{js,ts,vue,blade.php} so module-contributed classes are picked up by the host CSS pipeline.
Installation wizard PreferencesView was already in the tree waiting for the API field rename (date_formats, time_zones, fiscal_years, languages) that landed in setting.service.ts; this commit catches both sides up together.
Now that the legacy v1 frontend (commit 064bdf53) is gone, the v2 directory is the only frontend and the v2 suffix is just noise. Renames resources/scripts-v2 to resources/scripts via git mv (so git records the move as renames, preserving blame and log --follow), then bulk-rewrites the 152 files that imported via @v2/... to use @/scripts/... instead. The existing @ alias (resources/) covers the new path with no extra config needed.
Drops the now-unused @v2 alias from vite.config.js and points the laravel-vite-plugin entry at resources/scripts/main.ts. Updates the only blade reference (resources/views/app.blade.php) to match. The package.json test script (eslint ./resources/scripts) automatically targets the right place after the rename without any edit.
Verified: npm run build exits clean and the Vite warning lines now reference resources/scripts/plugins/i18n.ts, confirming every import resolved through the new path. git log --follow on any moved file walks back through its scripts-v2 history.
