Release v6.0.0

[kishore7snehil]

This is the first stable release of the v6 line. It introduces breaking changes to the Management API. Please consult the v6 Migration Guide for detailed upgrade instructions.

🚀 What's New

This release marks a major milestone for the Auth0 Ruby SDK. The Management API client has been completely rewritten using the Fern code generation tool, built directly from the Auth0 OpenAPI specification. This delivers complete, always-up-to-date API coverage with full type safety. The Authentication API is ported from v5 and maintains full feature parity.

✨ Highlights

• 🏗️ Auto-generated Management API - Rebuilt from the Auth0 OpenAPI spec using Fern, ensuring complete endpoint coverage and consistency with the API
• 🔒 Strongly-typed responses - No more raw hashes. Every response is a typed object with attribute readers
• 📄 Built-in pagination - List methods return iterators that automatically fetch pages as you iterate with each
• 🔑 Automatic token management - The unified Auth0::Client handles the OAuth 2.0 client credentials grant, token caching, and a new token_provider option for supplying tokens from an external source
• ⚡ Built-in retry - Automatic retries with exponential backoff for transient failures (408, 429, 5xx)
• 🛡️ Exception-driven error handling - Non-2xx responses raise typed exceptions (Auth0::Errors::NotFoundError, etc.) instead of returning error hashes
• 📦 Leaner gem - The published gem now ships only runtime files (bin/, test/, spec/, features/ are excluded), reducing package size and scanner false positives

🔄 What's Changed

The Management API has breaking changes:

Area	v5	v6
Client	Auth0Client.new(...)	Auth0::Client.new(...) (alias Auth0Client retained)
Sub-client access	client.users(per_page: 10)	client.users.list(per_page: 10)
Get one	client.user('auth0|123')	client.users.get(id: 'auth0|123')
Sub-resources	client.get_user_roles(user_id)	client.users.roles.list(id:)
Params	Positional args + option hashes	Keyword arguments
Responses	Raw hashes	Typed objects (user.email)
Pagination	Arrays	`client.users.list.each {
Error handling	Error hashes	rescue Auth0::Errors::NotFoundError
API version	api_version: 2	Removed (v2 only)
HTTP layer	rest-client	net/http (built-in)
Minimum Ruby	>= 2.5	>= 3.3

The Authentication API is unchanged - code written against it in v5 works in v6 with no changes.

📦 Installation

gem install auth0

🔧 Quick Start

require 'auth0'

client = Auth0::Client.new(
  client_id: ENV['AUTH0_CLIENT_ID'],
  client_secret: ENV['AUTH0_CLIENT_SECRET'],
  domain: ENV['AUTH0_DOMAIN']
)

# List users with automatic pagination
client.users.list(per_page: 50).each do |user|
  puts user.email
end

# Create a role
role = client.roles.create(name: 'admin', description: 'Administrator role')
