With that being said let’s jump right in with all the updates from Ruby on Rails world.
New Docs PRs for Review
Two new RRs for documentation are open for review:
EncryptedConfiguration: Raise when using a key that can't respond to #to_sym
As is the case when trying to use an integer as a key, which is unsupported.
This replaces the following less-friendly error:
With a more helpful error message:

Deferred route drawing to the first request, or when url_helpers called
The initial reload of routes is now triggered either via middleware or when a method is invoked. Previously, this process occurred unconditionally during boot, which could unnecessarily slow down the startup time in larger applications with many routes. In environments like production, where , routes will still be eagerly loaded at boot time.

Added route helper for WebSockets
Rails did not have a nice route helper for and WebSockets.
Previously you'd need to write something like this:
With this change, we can write:

EncryptedAttributeType#type now returns cast_type's type
This Pull Request changes two things:
it delegates method to actual instead of using one from
it changes class from which is inherited to a more generic .

Enabled query log tags by default on development env
This can be used to trace troublesome SQL statements back to the application code that generated these statements.

ActiveRecord: Bulk insert fixtures on SQLite
SQLite supports bulk inserts, but one insert was created for each fixture. This PR makes it behave like the other adapters, creating a single bulk insert per fixture table and making tests with SQLite considerably faster.

Supported minitest 5.25+
Minitest 5.25+ has a new API for with_info_handler that accepts an additional argument. Rails now supports all versions of minitest 5.

Updated PostgreSQLAdapter#extensions to include schema name
This allows the schema dumper's generated enable_extension statements to include the schema name, if different from .

ActionDispatch::Journey::Parser - Removed RACC
This Pull Request changes ActionDispatch::Journey::Parser to not be generated by racc.

Added escape_html_entities option to JSON encoder
This Pull Request changes JSON encoding code to accept an optional flag for whether or not to escape entities (). If not supplied, the existing global configuration flag will be used instead.
With this change, you can do as follows:

Allowed use of alternative database interfaces
Currently running rails is hardcoded to use the default interface for the given database (e.g. for ).
This PR allows the use of alternative interfaces by specifying the key in the database configuration.

Inferred default :inverse_of option for delegated_type
Before this commit, delegated types were unable to infer their inverse associations, so saving records built with the generated # methods weren't written to all the necessary places. For example:
When using delegated types, we can now infer the option for the association.

Encryption casting with encrypts before serialize
This PR ensures encrypted binary data is properly handled in PostgreSQL.

Supported dumping PostgreSQL inheritance & partitioning options to schema.rb
provides an options: key that allows you to append options to your table definition. One of the things you can do this way with 10+ uses native partitioning to declare partitioning definitions:
Adding this to a migration and running it will properly create the partitioned table in development, but the dumped schema will not persist the specified partitioning options. Therefore, if you run your test suite which loads from , your test database's table won't be properly partitioned.
This PR extends the adapter's schema statements so that it can dump this partitioning definition as defined in the relevant system tables.

Added store_if_blank option to has_rich_text
This PR introduces a . It defaults to true(the current behavior); if you pass false, AT won't create records when saving with a blank value.

SQLite non-GVL-blocking, fair retry interval busy handler
This PR improves SQLite connection handling for timeouts, by avoiding Ruby's Global Variable Lock (GVL) it can reduce SQLite3::BusyException errors and latency.

Fixed Devcontainer generator with --dev option path error
This Pull request moves the definition to module rather than adding it to in AppGenerator definition. It also creates a constant in , so that it can be used consistently in tests.

Striped encrypted file contents
This Pull Request strips the content file as well after reading to make sure it can be decrypted successfully.

Added support for SQLite3 full-text-search and other virtual tables
Rails now support SQLite3 full-text search and other virtual tables. Previously, adding SQLite3 virtual tables would cause issues with , but with this update, virtual tables can now be safely added using .

Supported custom environments on bin/rails credentials:diff
This Pull Request changes the way the environment is looked up. In addition to the current lookup in the available environments, it adds a fallback and it returns the name of the file in the provided path.

Rails 8 - Solid Cache is the new default caching backend
Solid Cache will be the new default caching backend for production deployments out of the box in Rails 8. We're also going to add Solid Queue by default, and both solid options will be bundled behind the same flag.

Rails 8 - Configured Solid Queue alongside Solid Cache by default
Solid Queue will be the new default DB-based queuing backend for Active Job out of the box in Rails 8.

Rails 8 - Added Solid Cable
Solid Cable is a database-backed Action Cable adapter that keeps messages in a table and continously polls for updates. This makes it possible to drop the common dependency on Redis, if it isn't needed for any other purpose. Despite polling, the performance of Solid Cable is comparable to Redis in most situations. And in all circumstances, it makes it easier to deploy Rails when Redis is no longer a required dependency for Action Cable functionality.
Solid Cable is the last piece before we can fully claim that Rails 8 only requires a database as a dependency to get access to all frameworks and functionality.

Updated TimeWithZone#inspect to match Ruby 1.9+ ISO 8601 format
This updates TimeWithZone#inspect to match the ISO 8601 style time which Ruby has used for Time#inspect since 1.9+ instead of the variant of rfc822. This makes TimeWithZone match Time's formatting except for the precision in the timestamp and including the zone's name.
This only impacts TimeWithZone#inspect, TimeWithZone#to_s had already been updated to use the new ISO 8601 style formatting. Because #inspect should just be used for presenting the time to developers, I don't think we need do go through a deprecation cycle for it.

Allowed registering test directories for CodeStatistics

Fixed authentication generator double signature

Silenced healthcheck requests from the log
The default Rails health check is intended to be hit every second or so by Kamal to ensure that the application is still or has just become responsive. This clutters up the production logs and makes it hard to follow what's actually going on. This adds a new middleware called that is used by a new config to prevent that.

Deprecated Benchmark.ms and add benchmark to the gemspec
Ruby plans to make benchmark a bundled gem - This change sets up the deprecation of Rails core extension in favour of the bundled gem for the future.

Enabled DependencyTracker to evaluate interpolated paths
Previously, neither the PrismRenderParser nor the RipperRenderParser would consider an interpolated string as a dependency. The RubyTracker even included a line to explcitly filter out interpolated paths returned from the RipperRenderParser since they would end in a "/". However, the RubyTracker does include the ability to evaluate explicit "Template Dependency" comments with wildcard nodes.
This commit extends the RipperRenderParser and PrismRenderParser to convert interpolated strings into wildcard globs. Additionally, it changes the RubyTracker to evaluate wildcards the same for both implicit and explicit dependencies. This enables the RubyTracker to identify potential dependencies for interpolated renders, which it was previously unable to do.

alias_attribute: handle user defined source methods
