We've just released Solidus v3.1.0!

Thanks to all contributors, testers, and users who made this release possible.

This version's support will end in 18 months: 2023-03-10.

What's next?

For the next minor release (3.2.0), we plan to make huge changes to the Event Bus, in order to provide a solid architecture with a set of tools that will help developers use this feature. We are planning to release a new adapter along with the current one, to allow Solidus' users some time to switch, which could require some code change in the host applications.

The main features of the new Event Bus Adapter are:

  • Isolation from ActiveSupport::Notification.
  • Better observability for event-generated flows.
  • Better testability.
  • More robust events registration.

What changed on Solidus 3.1

Here's what changed in the last released version. If you have any trouble updating or you want to leave some feedback, please use this GitHub Discussion.

Major changes

Spree.load_defaults: preference defaults depending on the Solidus version

Solidus 3.1 brings a new feature where preference defaults can take different values depending on a specified Solidus version. It makes it possible to stop deprecating old defaults every time we introduce a change in the recommended value for a setting. After all, they're just that; recommendations. Instead, now users can explicitly ask for a given Solidus version defaults and, as before, override the preferences they want.

When upgrading to 3.1, you have to take action to adopt the new behavior. You'll need to add Spree.load_defaults('3.1') on the very top of your spree.rb initializer. As we're not changing any preference default on this release, nothing will break. A warning will be emitted on boot-up until you do it!

However, bumping the version given to load_defaults straight away for future upgrades will not be a safe option. Instead, you'll have to go through the new update process detailed below.

Take a look at #4064 for more information.

New update process

As aforementioned, preference defaults can change after a Solidus release. Once you have your defaults locked to the current Solidus version, a new upgrade won't break your application because of them. However, it's a good idea to adapt your application to the updated recommended settings. To help with this process, Solidus comes with a generator that you can execute like this:

bin/rails g solidus:update

That generator will create a new initializer called new_solidus_defaults.rb, which will preview all the defaults that have changed between versions, each on a commented line. From that point, you can activate the new defaults one by one and adapt your application incrementally. Once you're done with all of them, you can bump the version given to Spree.load_defaults in the spree.rb initializer and remove the new_solidus_defaults.rb initializer altogether.

You can read in more detail about this process on our guides.

On #4087 you can find more.

Other important changes

Spree::Price#amount field can no longer be nil. Besides adding the validation at the model layer, we ship with a task that will remove records where the amount is NULL in the database. You should run the task before executing the new migrations:

bin/rails solidus:delete_prices_with_nil_amount
bin/rails railties:install:migrations
bin/rails db:migrate

If you're running migrations automatically on deploy, you should run the task before rolling out the new code. In that case, you first should make sure that you have affected records:

Spree::Price.where(amount: nil).any?

If the above code returns false, you don't need to do anything else. Otherwise, copy the task into your code, and deploy & execute it. Another option is to execute it manually in your console in production. However, be extremely careful when doing that!! :warning: :warning: :warning:

Spree::Price.where(amount: nil).delete_all

Take a look at PR #3987 for more details.
