1.4.1 on the 25th of September 2025

• We've fixed a warning message which could appear with the FedEx plugin when the letters service wouldn't be selected in the shipping method.

1.4.0 on the 20th of September 2025

• The processing category setting now has a "all" choice so that both MACHINABLE and NONSTANDARD rates can be taken into account.
• We've added a rate indicator restriction setting. This will allow you to select some rate indicators and the plugin will only take the rates for these. It can be useful when shipping things that are not normal rectangular packages.
• The letters rate wouldn't be displayed when only the letter service would be selected.
• We've improved some error messages in the plugin.

1.3.1 on the 17th of September 2025

• The version number was not properly set in the XML of the USPS plugin.
• The services name will now also use the translation text instead of the key.
• The plugin now checks for the minimum dimensions for the letters API so that the rate can be retrieved.

1.3.0 on the 16th of September 2025

• We've added the "First-Class Mail" service to the USPS plugin for letters and flats.
• The USPS plugin now uses either the total endpoint or the letter endpoint automatically based on the dimensions and weight of the elements in the cart.
• We've fixed an issue with the display of the shipping method / service name in orders.
• We've added back the "Processing category" setting with only MACHINABLE and NONSTANDARD choices so that you can choose which kind of processing category you want to use for packages.

1.2.0 on the 15th of September 2025

• We've switched to using another endpoint of the USPS prices v3 API in order to be able to take into account letters and flats.

1.1.0 on the 8th of September 2025

• The domestic shipping API the plugin implemented was not working properly. We changed to another API and it now works. We had to add several settings for this: "Processing Category", "Rate Indicator", "Entry Facility Type" and "Price Type".
• We've added a "Has non standard characteristics" setting you can activate for domestic shipping when shipping cylindrical tubes or rolls, certain high-density items, cartons containing more than 24 ounces of liquids in one or more glass containers, cartons containing 1 gallon or more of liquid in metal or plastic containers, and parcels with contents that may cause the parcel to roll or not maintain the integrity of the packaging during processing.
• We've added tooltips to many of the options of the plugin so that the merchant can better understand what to do.

1.0.0 on the 16th of June 2025

• Initial release of the plugin
