+Hi, it's [zzak](https://github.com/zzak). Let's explore this week's changes in the Rails codebase.
+
+**Message from the Rails Foundation**  
+While Rails World sold out quickly this year, a friendly reminder that the sessions will be recorded and published on YouTube quickly- the Opening and Closing Keynotes immediately, with all other sessions published shortly thereafter.  
+If you didn’t manage to get a ticket, this is a fantastic opportunity to check out some of the other Ruby events taking place this year: <https://rubyconferences.org/>
+
+[Add ActiveRecord::Result#affected_rows](https://github.com/rails/rails/pull/55060)  
+The result returned from calling [exec_query](https://edgeapi.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/DatabaseStatements.html#method-i-exec_query) now provides a method to get the number of affected rows.
+
+```ruby
+# Get the number of rows affected by the query:
+result = ActiveRecord::Base.lease_connection.exec_query <<~SQL.squish
+  INSERT INTO posts (title, body)
+  VALUES ("title_1", "body_1"), ("title_2", "body_2")
+SQL
+result.affected_rows
+# => 2
+```
+
+[Drop vendored Trix files in favor of the "action_text-trix" gem](https://github.com/rails/rails/pull/55058)  
+This change shouldn't have affect on applications, but makes maintenance easier for the Rails team.
+Meaning that bug fixes or security patches to Trix no longer have to wait for a Rails release to be available for application developers.
+
+[Bump Trix to v2.1.15](https://github.com/rails/rails/pull/55046)  
+Speaking of which, [CVE-2025-46812](https://github.com/advisories/GHSA-mcrw-746g-9q8h) was fixed in the latest release of Trix. Please update your applications as soon as possible.
+
+[Only load from CGI when required for Ruby 3.5](https://github.com/rails/rails/pull/55037)  
+By [retiring CGI](https://bugs.ruby-lang.org/issues/21258) from Ruby's Standard Library of bundled gems, Rails was updated to load the `cgi/escape` which is still supported without emitting warnings from the other parts of the gem.
+
+[Add support for Cache-Control request directives](https://github.com/rails/rails/pull/55033)  
+This PR adds support for various cache control directives in requests to control how caching is handled by the HTTP client.
+Based on [RFC-9111](https://www.rfc-editor.org/rfc/rfc9111.html#name-request-directives) which details strategies for `max-age`, `max-stale`, `min-fresh`, and `no-cache`.
+
+```ruby
+def show
+  if request.cache_control_directives.only_if_cached?
+    @article = Article.find_cached(params[:id])
+    return head(:gateway_timeout) if @article.nil?
+  else
+    @article = Article.find(params[:id])
+  end
+  render :show
+end
+```
