While the changelog (opens new window) is the most comprehensive list of changes, this guide provides a high-level overview and organizes changes by category.
Previously, Postie provided a means to fetch rates manually through the existence of a POST variable. Instead, we have changed this to allow for certain routes to only allow the fetching of rates, which is of course configurable.
To refresh why this is needed — as soon as your cart has a valid address, Commerce will prompt Postie to fetch shipping rates. This slows down the process of dealing with your cart, which is incredibly detrimental to the shopping experience.
This behaviour is enabled by default. You will need to add all routes where you wish to fetch shipping rates.
This is an important step to check in your installation! If you have a custom path for your shipping page, this setting will need to be configured to reflect your checkout route.
<?php
return [
'*' => [
'enableRouteCheck' => true,
'routesChecks' => [
'/shop/checkout/shipping',
'/shop/cart',
],
]
];
All shipping logic has now been extracted to a separate verbb/shippy (opens new window) package. This has been a major refactor of how providers work but is mostly under-the-hood work, with some exciting benefits such as tracking and label functionality.
What this means is that this should not pose any changes to how Postie works, but if you've developed any custom providers, these will need to be updated to be compatible with Shippy.
Providers are now stored in a dedicated project config set, rather than bundled with your project.yaml main file. This provides better performance for your yaml files, which previously stored settings for every provider whether they were enabled or not.
Secondly, providers are now created on-demand, rather than all being available to configure. You will need to create a new provider if you want to use one. This gives you the flexibility to create multiple providers.
Postie's migration will have automatically created any enabled providers before the update, but it's worth checking that your providers and settings are in place. Some will also require some manual changes due to updated APIs.
Settings for a provider set via a config/postie.php configuration file have changed slightly. Settings are now "flat" rather than being in a settings key. For example:
// Postie v3
'providers' => [
'australiaPost' => [
'name' => 'Australia Post',
'settings' => [
'apiKey' => '•••••••••••••••••••••••••••••',
],
],
],
// Postie v4
'providers' => [
'australiaPost' => [
'name' => 'Australia Post',
'apiKey' => '•••••••••••••••••••••••••••••',
],
],
To save confusion and potential misconfiguration, we have removed the Weight Unit and Dimension Unit settings for all providers. This is now determined automatically for the provider and the origin country.
We have also removed the "Connection Tester" functionality to something more meaningful with the Rates Testing utility. This provides essentially the same functionality, with the additional benefit of being able to set the addresses and package for a rate request and see the rates that are reported back.

Previously, this was bundled with the FedEx provider, but to simply handling, it's been extracted to its own provider. This also helps to combine both freight and non-freight rates if you wish.
This includes the same changes to the main FedEx provider.
