Introducing the permify config Command

cache_check_count Added for Improved Caching Insights

OIDC Configuration and Validation Enhancements

Improvements on Logging

• Context relation errors will now only be logged in debug mode.
• Added unary and stream server interceptors to the logging configuration, enabling detailed start-end logs for GRPC calls, including timestamps, method details, and execution times

Fix & Enhancement in Error Codes

Enhanced Request Deduplication

Performance Optimization: PostgreSQL Index Enhancements

Added Helm Charts for Kubernetes Deployment

Refactor on Circuit Breaker

Data Bundles - Streamline Data Sync

Flexible Input Formats for Schema in Testing Validation File

Authentication for Consistent Hashring

Implement slog Logging in Postgres

• If you're new to slog, check out the post Structured Logging published on the Go blog.
• For details of this development see the respected Github Pull Request

Playground Improvement

• Visualization of the schema now can be accessed from the tab above the schema.
• Improve the editor on the enforcement section in order to make scenario creation smother.
• Separate the relation and attribute creation. You can easily create relations and attributes using an analog click-and-fill form.

Improvements on Distributed Cache Mechanism

• Updated Consistent Hashring configuration and usage. Here is an example configuration option for it from our configuration YAML file,
• Implement consistent hashring balancer with go-grpc. This gives ability to create a load balancer policy when providing DNS or Kubernetes addresses. This enhancement not only boosts performance but also eliminates the need for a separate service for user-specific service discovery.

Regex Enhancements in APIs' Validation

String Validation: ^[a-zA-Z_]{1,64}$"

• Contain only uppercase letters (A-Z), lowercase letters (a-z), and underscores (_).
• Have a length between 1 and 128 characters.
• Alternatively, the ID can be a single asterisk ().

ID Validation: ^([a-zA-Z0-9_\\\\-@\\\\.:+]{1,128}|\\\\*)$

• Contain only uppercase letters (A-Z), lowercase letters (a-z), and underscores (_).
• Have a length between 1 and 128 characters.
• Alternatively, the ID can be a single asterisk ().

Added Permify Schema to JSON converter

By utilizing the command: permify ast {path of your schema validation file}, you can effortlessly convert your model into an Abstract Syntax Tree (AST) representation.

General Enhancements on Logging

• Migrated to Go’s slog structured logger, for improved logging capabilities.
• Introduced slog logger configuration and level resolver, allowing for more flexible and customizable logging.
• Changed distributed mode failure log to use Error level.
• Redundant logger instantiation has been removed, streamlining the codebase and potentially improving efficiency.

Released ABAC (Attribute-Based Access Control) Support

We have released ABAC (Attribute-Based Access Control) support for our open-source, introducing several new features, including:

• The ability to define attributes and rules (functions that allow you to check specific mostly dynamic conditions) when creating a schema.
• Addition of new datastore interfaces designed specifically to store attributes.
• Re-designed the check engine algorithm for attribute computation.
• Implementation of mass filters for attributes and improved error handling mechanisms to enhance visibility and user experience.

UI & Functionality Improvements on Playground

• Added ABAC variables; rules and attributes to Visualizer.
• Adjusted the height of it for better visibility and user experience.
• Introduced a new schema reader for defining cache keys type. Rule calls now always initiate from the invoker (that's for caching rule calls with specific entity).

Added Coverage Configuration (coverage.yml)

Introduced a GitHub Action that activates on pushand pull_request events. Utilizes ubuntu-latest runner with Go 1.20 setup. Checks out the project code and manages dependencies. Executes unit tests and gathers code coverage. Reports coverage metrics to Coveralls.

Improvements on Lookup Services

• Unified lookup services to read the schema only once per request for efficiency.
• Introduced a new cache mechanism within the lookup: Schema Map. It serves as a cache to store and keep track of schema versions, ensuring efficient and speedy retrievals.

Notable Enhancements On Core

• Renamed conflicting proto messages to avoid clashes with native types.
• Implemented checkDirectCall for recursive invokes. Rule calls now always initiate from the invoker (that's for caching rule calls with specific entity).
• Enhanced array data type handling, with the addition of array types to engines and new attribute helpers.
