+Hi, it's [zzak](https://github.com/zzak). Let's explore this week's changes in the Rails codebase.
+
+The [Rails World CFP](https://sessionize.com/rails-world/) will close in just one week on March 21.  
+Submit your talk in time!
+
+[Active Record Basics Guide](https://github.com/rails/rails/pull/51226)  
+This PR refreshes the guide covering the basics of Active Record.
+
+[Do not try to alias on key update when raw SQL is supplied](https://github.com/rails/rails/pull/51325)  
+A bug was found when updating duplicates with raw SQL.
+
+[Memoize "key_provider" from "key" or deterministic "key_provider" if any](https://github.com/rails/rails/pull/51324)  
+Previously, this memoization was removed which lead to a performance hit for encrypted attributes.
+
+[Updating Astana with a Western Kazakhstan timezone](https://github.com/rails/rails/pull/51317)  
+On March 1, 2024, Kazakhstan (all parts) switched to a single time zone UTC+5.  
+Using the latest [tzinfo-data](https://github.com/tzinfo/tzinfo-data/releases/tag/v1.2024.1) that updated the Kazakhstan timezones, ActiveSupport still showed the incorrect offset because it was pointing to the `Asia/Dhaka` Bangladesh timezone, which will not get the same TZ offset change.
+
+[Preserve encoding on "truncate_bytes"](https://github.com/rails/rails/pull/51313)  
+This PR addressed an issue where `String#truncate_bytes` can return a string with a different encoding than the one being truncated.
+
+[Support custom blob key in ActiveStorage::Blob.compose](https://github.com/rails/rails/pull/51299)  
+Since Rails 6.1, Active Storage has allowed to provide a custom `key` when attaching a new file.  
+This PR adds support when using the `compose` class method to customize the name of the underlying service object.
+
+[Fix MySQL adapter for inserts with aliases](https://github.com/rails/rails/pull/51286)  
+This pull request addresses errors that occur when using MySQL 8.0.18 or lower version of MySQL 8.0.
+
+[Railties configure sanitizer vendor in 7.1 defaults more robustly](https://github.com/rails/rails/pull/51267)  
+In order to avoid an issue where Rails::HTML::Sanitizer is not yet loaded, which resulted in the sanitizer vendor remaining as `Rails::HTML4` and not be set to `Rails::HTML5` as intended in Rails 7.1.
