Users can now generate serializers via the command line using \rails generate serializer\. This new generator creates a serializer class in \app/serializers\ that includes \FastJsonapi::ObjectSerializer\ and defines the specified attributes.

The library now includes built-in support for performance monitoring via ActiveSupport::Notifications. New files in the \instrumentation\ directory add \serializable\_hash\ and \serialized\_json\ methods that wrap the original serialization logic, emitting \SERIALIZable\_hash\_notification\ and \SERIALIZED\_JSON\_NOTIFICATION\ events respectively. Additionally, specific normalizers for the Skylight APM tool are introduced to properly categorize these new trace events, ensuring that serialization steps are correctly identified in performance traces.

The library now conditionally loads the \has\_one\ extension only when ActiveRecord is present, and only loads the Rails-specific railtie when Rails is detected. This prevents errors when ActiveRecord is not required in a project, allowing the library to be used with other ORMs or in environments without ActiveRecord. Additionally, the \has\_one\ extension was updated to handle cases where an attribute is already defined with the same name, using \read\_attribute\ in that scenario.

The project is now marked as no longer maintained, with a warning added to the README header and a link to a forked project. The README has been significantly updated to include documentation for new features such as Rails generator usage, key transforms, conditional attributes/relationships, sparse fieldsets, and helper methods. Additionally, the gem version was bumped from 1.0.16 to 1.0.18, and the build configuration was updated to test against Ruby 2.2, 2.3, 2.4, and 2.5.

The library refactors its internal architecture by introducing dedicated classes for Attribute, Link, and Relationship, replacing the previous hash-based configuration. This enables new capabilities: users can now define custom links and meta information for resources, pass serialization parameters (params) through nested includes, and conditionally include relationships or attributes based on a provided proc. The change also improves polymorphic relationship support and allows customizing the ID method name.

Add comprehensive test coverage for serializer features; Added shared example definitions for object serializer tests; Added test coverage for Active Record extensions and has\_one through associations; Added test coverage for Result chaining; Added tests for FastJsonapi instrumentation; Expanded test fixtures for complex object relationships; Expanded test suite with new serializers and performance filters.

The project's dependency management has been streamlined. The \Gemfile\ now delegates all dependencies to \fast\_jsonapi.gemspec\, and the \Gemfile.lock\ has been removed. The \gemspec\ now explicitly requires Ruby version 2.0.0 or higher. Runtime dependencies for \activesupport\ and \activerecord\ have been relaxed from version 5.0 to \\>= 4.2\. Additionally, \jsonapi-rb\ and \jsonapi-serializers\ have been added as development dependencies.
