+
+Hey everyone, Happy Friday!
+
+[Vipul](https://www.saeloun.com/team/vipul) here with the latest updates for This Week in Rails. 
+
+Before we start, a small update - I am happy to share that my team at Saeloun is joining the Rails Foundation as a contributing member.
+Read more about the reasons why we decided to join [here](https://rubyonrails.org/2025/1/10/saeloun-joins-rails-foundation), and why you should too!
+
+[Colorize console prompt on non standard environments](https://github.com/rails/rails/pull/53027)  
+Currently, the Rails console prompt is colored according to the following rules: blue for dev and test, red of prod.
+On non-standard environments (like staging), the prompt is not colored. With this change, it will now be set to Magenta, for these environments.
+
+[Fix running individual app:update commands](https://github.com/rails/rails/pull/54098)  
+This change fixes a regression, where the individual `app:update` commands (like `app:update:configs` or `app:update:bin`) could no longer be run on their own, 
+as they require the app to be loaded and it no longer was.
+
+[Fix backtrace of ArgumentErrors raised during template rendering](https://github.com/rails/rails/pull/54133)  
+Before this fix, any argument error in a template with strict locals would be swallowed and be replaced by an exception with unrelated backtrace, 
+which made debugging templates difficult.
+With this change, any `ArgumentError` unrelated to strict locals is re-raised, preserving the original backtrace for developers.
+
+[Fix local variable access in layouts](https://github.com/rails/rails/pull/54020)  
+Layouts now have access to local variables passed to `render`.
+This fixes a very old regression introduced in Rails 5.1!
+
+[Sort table columns by name when dumping schema](https://github.com/rails/rails/pull/53281)  
+The table columns inside `schema.rb` are now sorted alphabetically.
+Previously they'd be sorted by creation order, which can cause merge conflicts when two branches modify the same table concurrently.
+
+[Update NotificationAssertions's assert_notifcation to match against payload subsets and return matched notification](https://github.com/rails/rails/pull/54126)  
+`ActiveSupport::Testing::NotificationAssertions`'s `assert_notification` now matches against payload subsets by default.
+
+Previously the following assertion would fail due to excess key values in the notification payload. Now with payload subset matching, it will pass.
+
+```ruby
+assert_notification("post.submitted", title: "Cool Post") do
+  ActiveSupport::Notifications.instrument("post.submitted", title: "Cool Post", body: "Cool Body")
+end
+```
+
+Additionally, you can now persist a matched notification for more customized assertions.
+
+```ruby
+notification = assert_notification("post.submitted", title: "Cool Post") do
+  ActiveSupport::Notifications.instrument("post.submitted", title: "Cool Post", body: Body.new("Cool Body"))
+end
+assert_instance_of(Body, notification.payload[:body])
+```
+
+[Load configured Active Storage plugins during boot](https://github.com/rails/rails/pull/45100)    
+Previously, the parts of Active Storage using `ruby-vips`, `mini_magick`, or `image_processing` would try to load gems only when used. 
+This strategy works well because it allows apps that don't need these features to easily ignore them and not have to depend on gems they don't need.
+
+However, the downsides to this strategy was that it requires loading code during requests and that it moves potential error messages into request
+logs instead of those errors being immediately visible on boot.
+
+[Introduce RAILS_MASTER_KEY placeholder to CI template](https://github.com/rails/rails/pull/52230)  
+The existing CI templates do not work as expected if custom credentials are utilized, or if `config.require_master_key` is enabled.
+This change introduces `RAILS_MASTER_KEY` placeholder in generated `ci.yml` files, to address this issue.
+
+[Don't load ActiveStorage::Blob when validating the service](https://github.com/rails/rails/pull/54142)  
+For tasks like `assets:precompile` that don't need it, we should not be loading the entire ActiveStorage code, and instead just relevant parts.
+
+[Use the given form in html_options for the hidden field in collection_check_boxes](https://github.com/rails/rails/pull/51746)  
+Respect `html_options[:form]` when `collection_checkboxes` generates the hidden `<input>`.
+
+[Deprecate String#mb_chars and AS::Multibyte::Chars](https://github.com/rails/rails/pull/54081)  
+These APIs are a relic of the Ruby 1.8 days when Ruby strings weren't encoding aware.
+
+[Deprecate ActiveSupport::Configurable](https://github.com/rails/rails/pull/53970)  
+This was only used once internally by Rails, and is now deprecated going ahead.
