Upgrading to Rails
7.0
If you're upgrading an existing application, it's a great idea to have good test
coverage before going in. You should also first upgrade to Rails
6.1 in case you
haven't and make sure your application still runs as expected before attempting
an update to Rails
7.0. A list of things to watch out for when upgrading is
available in the
Upgrading Ruby on Rails
guide.

Notable changes
Rollback transactions when the block returns earlier than expected.
Before this change, when a transaction block returned early, the transaction would be committed.
The problem is that timeouts triggered inside the transaction block was also making the incomplete transaction to be committed, so in order to avoid this mistake, the transaction block is rolled back.
Merging conditions on the same column no longer maintain both conditions, and will be consistently replaced by the latter condition.
# Rails 6.1 (IN clause is replaced by merger side equality condition) Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob] # Rails 6.1 (both conflict conditions exists, deprecated) Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => [] # Rails 6.1 with rewhere to migrate to Rails 7.0's behavior Author.where(id: david.id..mary.id).merge(Author.where(id: bob), rewhere: true) # => [bob] # Rails 7.0 (same behavior with IN clause, mergee side condition is consistently replaced) Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob] Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => [bob]
