grocy/changelog/60_UNRELEASED_2020-xx-xx.md

!!! The major version bump is due to breaking API changes, please see below if you use the API

New feature: Link product of different sizes

• Imagine you buy for example eggs in different pack sizes
• The "Factor purchase to stock quantity unit" can now be set during purchase (if the products purchase and stock QU are different)
• Additionally, each product barcode can be assigned a different "Factor purchase to stock quantity unit" (on the product edit page), which is then automatically prefilled on the purchase page
• (Thanks @kriddles)

New feature: Permissions

• Users can now have permissions, can be configured per user on the "Manage users" page (lock icon)
• Default permissions for new users can be set via a new config.php setting DEFAULT_PERMISSIONS (defaults to ADMIN, so no changed behavior when not configured)
• All currently existing users will get all permissions (ADMIN) during the update/migration
• (Thanks @fipwmaqzufheoxq92ebc)

New feature: Reverse proxy authenticaton support

• New config.php settings AUTH_CLASS and REVERSE_PROXY_AUTH_HEADER
• If you set AUTH_CLASS to Grocy\Middleware\ReverseProxyAuthMiddleware and your reverse proxy sends a username in the HTTP header REMOTE_USER (header name can be changed by the setting REVERSE_PROXY_AUTH_HEADER), the user is automatically authenticated (and will also be created, if not already present)
• (Thanks @fipwmaqzufheoxq92ebc for the initial work on this)

Stock improvements/fixes

• When creating a quantity unit conversion it's now possible to automatically create the inverse conversion (thanks @kriddles)
• Optimized/clarified what the total/unit price is on the purchase page (thanks @kriddles)
• On the purchase page the amount field is now displayed above/before the best before date for better TAB handling (thanks @kriddles)
• Changed that when FEATURE_FLAG_STOCK_BEST_BEFORE_DATE_TRACKING is disabled, products now get internally a best before of "never expires" (aka 2999-12-31) instead of today (thanks @kriddles)
• Products can now be hidden instead of deleted to prevent problems / missing information on existing references (new checkbox on the product edit page) (thanks @kriddles)
• Improved/fixed that changing the products "Factor purchase to stock quantity unit" not longer messes up historical prices (which results for example in wrong recipe costs) (thanks @kriddles)
• On the stock journal page, it's now visible if a consume-booking was spoiled
• Added a "Clear filter"-button on the stock overview page to quickly reset applied filters
• Fixed that it was not possible to leave the "Barcode(s)" on the product edit page by TAB
• Fixed that when adding products through a product picker workflow and when the created products contains special characters, the product was not preselected on the previous page (thanks @Forceu)
• Fixed that when editing a product the default store was not visible / always empty regardless if the product had one set (thanks @kriddles)
• Fixed that FEATURE_SETTING_STOCK_COUNT_OPENED_PRODUCTS_AGAINST_MINIMUM_STOCK_AMOUNT (option to configure if opened products should be considered for minimum stock amounts) was not handled correctly (thanks @teddybeermaniac)
• Fixed that the "Expiring soon" sum (yellow header-button) on the stock overview page didn't include products which expire today (thanks @fipwmaqzufheoxq92ebc)
• Fixed that the shopping cart icon on the stock overview page was also shown if the product was on an already deleted shopping list (if enabled) (thanks @fipwmaqzufheoxq92ebc)
• Fixed that when editing a stock entry without a price, the price field was prefilled with 1
• Fixed that location & product groups filter on the stock overview page did a contains search instead an exact search
• Fixed that the amount on the success popup was wrong when consuming a product with "Tare weight handling" enabled
• Fixed that the aggregated amount of parent products was wrong on the stock overview page when the child products had not the same stock quantity units
• Fixed that edited stock entries were not considered for the price history chart on the product card

Shopping list improvements

• Decimal amounts are now allowed (for any product, rounded by two decimal places)
• "Add products that are below defined min. stock amount" always rounded up the missing amount to an integral number, this now allows decimal numbers

Recipe improvements/fixes

• It's now possible to print recipes (button next to the recipe title) (thanks @zsarnett)
• Improved recipe card presentation (thanks @zsarnett)
• Improved the recipe adding workflow (a recipe called "New recipe" is now not automatically created when starting to add a recipe) (thanks @zsarnett)
• Fixed that images on the recipe gallery view were not scaled correctly on largers screens (thanks @zsarnett)
• Fixed that decimal ingredient amounts maybe resulted in wrong conversions truncated decimal places if your locale does not use a dot as the decimal separator (thanks @m-byte)
• Fixed that a recipe cannot be included in itself (because this will cause an infinite loop) (thanks @fipwmaqzufheoxq92ebc)
• Fixed that when editing a recipe ingredient the checkbox "Disable stock fulfillment checking for this ingredient" was not initaliased with the saved value
• Fixed that when using the "+"-symbol (which appears on small screens only to expand columns which don't fit the screen) the page reloaded

Chores improvements/fixes

• Changed that not assigned chores on the chores overview page display now just a dash instead of an ellipsis in the "Assigned to" column to make this more clear (thanks @Germs2004)
• Fixed (again) that weekly chores, where the next execution should be in the same week, were scheduled (not) always (but sometimes) for the next week only (thanks @shadow7412)
• Fixed that the assignment type "In alphabetic order" did not work correctly (the last person in the list was always assigned next once reached) (thanks @fipwmaqzufheoxq92ebc)

Calendar improvements/fixes

• Events are now links to the corresponding page (thanks @zsarnett)
• Fixed a PHP warning when using the "Share/Integrate calendar (iCal)" button (thanks @tsia)
• Fixed that "Track date only"-chores were always displayed at 12am (are now displayed as all-day events)

API improvements/fixes

• Breaking changes:
  • All prices are now related to the products stock quantity unit (instead the purchase QU)
  • The product object no longer has a field barcodes with a comma separated barcode list, instead barcodes are now stored in a separate table/entity product_barcodes (use the existing "Generic entity interactions" endpoints to access them)
• Performance improvements of the /stock/products/* endpoints (thanks @fipwmaqzufheoxq92ebc)
• Fixed that the endpoint /objects/{entity}/{objectId} always returned successfully, even when the given object not exists (now returns 404 when the object is not found) (thanks @fipwmaqzufheoxq92ebc)

• Fixed (again) that CORS was broken

General & other improvements/fixes

• UI refresh / style improvements (thanks @zsarnett)
• The data path (previously fixed to the data folder) is now configurable, making it possible to run multiple grocy instances from the same directory (with different config.php files / different database, etc.) (thanks @fgrsnau)
  • Via an environment variable GROCY_DATAPTH (higher priority)
  • Via an FastCGI parameter (lower priority)
• The language can now be set per user (see the new user settings page / top right corner settings menu) (thanks @fipwmaqzufheoxq92ebc)
  • Additionally, the language is now also auto-guessed based on the browser locale (HTTP-Header Accept-Language)
  • The config.php option CULTURE was renamed to DEFAULT_LOCALE
  • So the used language is based on (in that order)
    • The user setting
    • If not set, then based on browser locale
    • If no matching localizaton was found, DEFAULT_LOCALE from config.php is used
• Performance improvements (page loading time) of the stock overview page (thanks @fipwmaqzufheoxq92ebc)
• The prerequisites checker now also checks for the minimum required SQLite version (thanks @Forceu)
• Replaced (again, added before in v2.7.0, then reverted in v2.7.1 due to some problems) QuaggaJS (seems to be unmaintained) by Quagga2
