+Hi, it's [Claudio Baccigalupo](https://github.com/claudiob).
+Let's explore this week’s changes in the Rails codebase.
+
+[Extend --minimal option](https://github.com/rails/rails/pull/54313)  
+`rails new --minimal` allows to create a basic Rails app, but recent additions to Rails were still included.
+Moving forward, this option will also skip Brakeman, CI, Docker, Kamal, Rubocop, Solid trifecta, and Thruster.
+
+[Add reply_to_address to Mail::Message](https://github.com/rails/rails/pull/53513)  
+When using Action Mailer you can now specify a `reply_to:` email address in addition to the `to:` recipient.
+
+[Load the routes in the console when calling app](https://github.com/rails/rails/pull/54380)  
+Have you ever needed to see what route helpers are available inside an IRB session?
+Moving forward they will be loaded in the `app` IRB helper.
+
+```sh
+$ bin/rails c
+$ > app.root_path # => "/"
+```
+
+[Fix rotate(on_rotation:)](https://github.com/rails/rails/pull/54371)  
+`MessageVerifier` and `MessageEncryptor` were intended to accept an `on_rotation` callback but that wasn't the case.
+This PR fixes the behavior.
+
+[Accept on_rotation argument in find_signed](https://github.com/rails/rails/pull/54373)  
+Building on the previous change, `find_signed` and `find_signed!` now accept an `on_rotation` callback.
+This callback is triggered whenever the `signed_id_verifier` uses rotated secret keys, making it valuable for monitoring and tracking purposes.
+
+[Make the devcontainer script work with podman](https://github.com/rails/rails/pull/54378)  
+[podman](https://podman.io/) is an alternative to Docker. 
+If you have it installed, the devcontainer script will use it, otherwise it will fall back to Docker.
+
+[Fix Active Record instrumentation to be thread safe](https://github.com/rails/rails/pull/54344)  
+When using Active Record async feature, the instrumentation was not thread safe.
+With the right race condition, instrumentation subscriptions would never fire up.
+
+[Fix inverting rename_enum_value options](https://github.com/rails/rails/pull/54394)  
+Did you know that you can rename an `enum` in your migrations using [rename_enum_value](https://edgeapi.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/PostgreSQLAdapter.html#method-i-rename_enum_value)?
+This commit fixes a bug so the `:from` and `:to` options are parsed correctly.
+
+[Fix routes being cleared when using reload_routes!](https://github.com/rails/rails/pull/54306)  
+Calling `Rails.application.reload_routes!` will now load all the routes without resetting them if they were already loaded.
+

+_We had [23 contributors](https://contributors.rubyonrails.org/contributors/in-time-window/20250124-20250131) to the Rails codebase this past week!_
+
+Until next time!
