+Hi, it's [gregmolnar](https://github.com/gregmolnar). Let's explore this week's changes in the Rails codebase.
+
+[New written & video tutorials for beginners](https://rubyonrails.org/2025/7/31/new-beginner-resources)  
+The Rails Foundation has launched a few more learning resources for beginners, in partnership with Chris Oliver and the team behind Typecraft - Chris Power and Robert Beene.
+
+[Log when `rescue_from` handles an exception](https://github.com/rails/rails/pull/55424)  
+This pull request adds a log message indicating when an exception was raised in
+`before_action` callbacks.
+
+[Allow hosts redirects from `hosts` Rails configuration](https://github.com/rails/rails/pull/55420)  
+With this change, it is possible to allow hosts redirects from the Rails configuration:
+```ruby
+    config.action_controller.allowed_redirect_hosts << "example.com"
+```
+
+[rate_limit notification instrumentation to include more payload](https://github.com/rails/rails/pull/55418)  
+To make it easier to move from rack-attack to the built-in rate limiter,  the `rate_limit.action_controller` notification now has the following additional payload values: count, to, within, by, name, cache_key.
+
+[Provide a method to check current transaction's isolation level](https://github.com/rails/rails/pull/55407)  
+This pull request adds `connection.current_transaction.isolation` API to check current transaction's isolation level.
+It returns the isolation level if it was explicitly set via the `isolation:` parameter
+or through `ActiveRecord.with_transaction_isolation_level`, otherwise returns `nil`.
+Nested transactions return the parent transaction's isolation level.
+
+[Add `relative_time_in_words` helper to ActionView](https://github.com/rails/rails/pull/55405)  
+This pull request introduces a `relative_time_in_words` helper:
+
+```ruby
+relative_time_in_words(3.minutes.from_now) # => "in 3 minutes"
+relative_time_in_words(3.minutes.ago) # => "3 minutes ago"
+relative_time_in_words(10.seconds.ago, include_seconds: true) # => "less than 10 seconds ago"
+```
