Hi, Wojtek here with more new Rails 7 changes.
The new Rails frontend approach and all the other new goodies can already be checked in this release.
Make ActiveModel::API the minimum API to talk with Action Pack and Action View. This will allow adding more functionality to ActiveModel::Model.
Generated columns are supported since version 12.0 of PostgreSQL. This adds
support of those to the Active Record PostgreSQL adapter.
Removed configurations are set by the default Rails configuration and can be still changed when needed.
CURRENT_TIMESTAMP provides differing precision depending on the database,
and not all databases support explicitly specifying additional precision. Instead, delegate to the new connection.high_precision_current_timestamp
for the SQL to produce a high precision timestamp on the current database.
