Hi, it’s <a href="https://github.com/zzak">zzak</a>. Let’s explore this week’s changes in the Rails codebase.

The <a href="https://sessionize.com/rails-world/">Rails World CFP</a> will close in just one week on March 21. 
Submit your talk in time!

<a href="https://github.com/rails/rails/pull/51226">Active Record Basics Guide</a> 
This PR refreshes the guide covering the basics of Active Record.

<a href="https://github.com/rails/rails/pull/51325">Do not try to alias on key update when raw SQL is supplied</a> 
A bug was found when updating duplicates with raw SQL.

<a href="https://github.com/rails/rails/pull/51324">Memoize “key_provider” from “key” or deterministic “key_provider” if any</a> 
Previously, this memoization was removed which lead to a performance hit for encrypted attributes.

<a href="https://github.com/rails/rails/pull/51317">Updating Astana with a Western Kazakhstan timezone</a> 
On March 1, 2024, Kazakhstan (all parts) switched to a single time zone UTC+5. 
Using the latest <a href="https://github.com/tzinfo/tzinfo-data/releases/tag/v1.2024.1">tzinfo-data</a> that updated the Kazakhstan timezones, ActiveSupport still showed the incorrect offset because it was pointing to the <code class="language-plaintext highlighter-rouge">Asia/Dhaka</code> Bangladesh timezone, which will not get the same TZ offset change.

<a href="https://github.com/rails/rails/pull/51313">Preserve encoding on “truncate_bytes”</a> 
This PR addressed an issue where <code class="language-plaintext highlighter-rouge">String#truncate_bytes</code> can return a string with a different encoding than the one being truncated.

<a href="https://github.com/rails/rails/pull/51299">Support custom blob key in ActiveStorage::Blob.compose</a> 
Since Rails 6.1, Active Storage has allowed to provide a custom <code class="language-plaintext highlighter-rouge">key</code> when attaching a new file. 
This PR adds support when using the <code class="language-plaintext highlighter-rouge">compose</code> class method to customize the name of the underlying service object.

<a href="https://github.com/rails/rails/pull/51286">Fix MySQL adapter for inserts with aliases</a> 
This pull request addresses errors that occur when using MySQL 8.0.18 or lower version of MySQL 8.0.

<a href="https://github.com/rails/rails/pull/51267">Railties configure sanitizer vendor in 7.1 defaults more robustly</a> 
In order to avoid an issue where Rails::HTML::Sanitizer is not yet loaded, which resulted in the sanitizer vendor remaining as <code class="language-plaintext highlighter-rouge">Rails::HTML4</code> and not be set to <code class="language-plaintext highlighter-rouge">Rails::HTML5</code> as intended in Rails 7.1.

You can view the whole list of changes <a href="https://github.com/rails/rails/compare/@%7B2024-03-08%7D...main@%7B2024-03-15%7D">here</a>.
We had <a href="https://contributors.rubyonrails.org/contributors/in-time-window/20240308-20240315">20 contributors</a> to the Rails codebase this past week!

Until next time!
