+Hi, it's [Greg](greg.molnar.io). Let's explore this week's changes in the Rails codebase.
+
+[Action Cable: Allow setting _nil_ as subscription connection identifier for Redis](https://github.com/rails/rails/pull/54931)  
+If you use Google Cloud Memorystore or another platform that blocks the command `CLIENT SETNAME` in Redis, previously you needed to overwrite the Redis connection factory. With this change, you can set the `id` of the connection to `nil` in the configuration.
+
+[Improve leap years counting performance in _distance_of_time_in_words_](https://github.com/rails/rails/pull/54923)  
+Before this change, the `distance_of_time_in_words` method could've lead to a denial of service if the given `from_time` and `to_time` arguments are far apart. This pull request replaced the concerning code with a constant calculation.
+
+
+[Allow to configure maximum cache key sizes](https://github.com/rails/rails/pull/54915)  
+This pull request adds the possibility to configure the maximum size for cache
+keys. When the key exceeds the configured limit (250 bytes by default), it will be truncated and the digest of the rest of the key appended to it.
+Note that previously `ActiveSupport::Cache::RedisCacheStore` allowed up to 1kb cache keys before truncation, which is now reduced to 250 bytes.
+This is how you can set it:
+```ruby
+config.cache_store = :redis_cache_store, { max_key_size: 64 }
+```
+
+[Use `TRUE` and `FALSE` for booleans in SQLite](https://github.com/rails/rails/pull/54911)  
+SQLite 3.23.0 added support for TRUE and FALSE as aliases for 1/0 (similar to MySQL). [Another pull request](https://github.com/rails/rails/pull/54907) bumped the minimum required SQLite version in Active Record to 3.23.0, and this one updates the boolean query generation for SQLite to use TRUE and FALSE.
