What's new in Blocks

Blocks Cloud is now Blocks OS. This release re-architects the platform around a unified operating console where every service runs on its own dedicated domain, migrates all applications to the new genesis-os frontend foundation on React 19, and ships a wave of new capabilities across Identity, Storage, Payments, and Workflow. It is the largest platform update since the 3.x line and the starting point for everything that follows.

Blocks OS Platform

The platform rename is more than branding — it reflects a re-architecture into independent, individually addressable services behind one console.

• A unified OS console — All services are now reached through a single shell at os.seliseblocks.com, with consolidated sidebar navigation and a service switcher that filters available applications by environment.

• A domain per service — Each capability now has its own dedicated subdomain instead of sharing one Cloud origin. Identity, Data, Workflow, Deployment, Observability, Localization, Utilities, Studio, and AI each run and scale on their own host.

• Identity & Access, in the console — User and Organization management has moved out of the standalone IAM frontend and now lives natively inside the OS console under Identity & Access, unifying administration with the rest of the platform.

• Environment data migration — A new migration engine moves each project's data into the per-environment architecture. Migrations are authorized, OTP-verified, and emit completion events so dependent services can react when a project finishes moving.

Identity

Identity gains a major set of authentication and access-management capabilities alongside the console move.

• Device Authorization flow (OAuth 2.0 / RFC 8628) — Blocks OS now supports the OAuth 2.0 Device Authorization Grant, enabling sign-in on input-constrained and headless clients (CLIs, terminals, TV apps) using a short user code.

• Social identity linking at signup — Users can link a social identity provider to their account during signup, streamlining onboarding across providers.

• User activation flow — A dedicated activation experience captures first and last name on the activation form, and administrators can resend activation to users who remain inactive.

• OIDC client management — Client secrets can now be rotated for OIDC clients, identity providers can be deleted, and credential saving supports an external discovery endpoint.

• Permission management overhaul — Dependent-permission selection is clearer and easier to reason about, built-in permissions are surfaced as read-only, permissions carry a severity, and permission groups can be created directly from the UI.

• Stronger session control — Logging out can now revoke multiple active sessions at once.

Storage & Data

Storage is now a full document management system, and the data layer gains query and metadata improvements.

• Document Management System (DMS) — A new content platform with fine-grained access control: content-access administration backed by an audit trail, file version history, move and zero-copy copy, cached folder ancestry with a cycle-guarded rebuild, and access-resolved children listing with cursor pagination. An effective-policy resolver evaluates access-control entries per request.

• Richer GraphQL queries — Queries now support logical AND / OR operators for more expressive filtering.

• Better resource metadata & docs — Permissions and resources carry names and descriptions, and the Data service ships published API documentation.

Workflow

• Rename workflows — Workflows can be renamed in place, and the workflow editor gains improved state management and input-panel handling.

Payments

Utilities introduces a complete Stripe-based payments experience.

• Stripe payments — Hosted checkout, saved cards (save and remove), and refunds are now supported end to end. Payments record the authenticated user, and the platform reuses a shopper's existing Stripe customer at checkout.

• Multiple providers — Payment providers can be registered and configured through the API and administered from dedicated provider pages, with provider credentials stored encrypted on the provider document and incoming events verified through Stripe webhook validation.

Localization

• genesis-os client — The Localization application has migrated to React 19 on the genesis-os foundation, and a new extension guide page documents the localization extension workflow.

Observability

• Driver updates & API exploration — The observability driver was updated across services, and Swagger is enabled for exploring the monitoring API.

Developer SDKs

The SDK line moved to v4.0 in lockstep with the platform, unified under the genesis-os name.

• genesis-os (React) v4.0 — @seliseblocks/blocks-kit is renamed to @seliseblocks/genesis-os@4.0.0 and now requires React 19.2.8 and react-router 8. It is the shared app-shell and component foundation consumed by every service application (IAM, OS, Data, Logic, Monitor, Release, Studio, Utilities, Localization), with an environment-aware app switcher. A React 19 / react-router 8 migration guide is published. (Breaking change.)

• Blocks Genesis (.NET) v4.0 — The .NET bootstrap SDK bumped to v4.0 alongside, adding formal versioning and analysis rulesets and picking up security updates.

• genesis-py v0.3.1 — The Python Genesis SDK received a maintenance update.

Release notes

This release enhances Blocks Cloud with improvements across AI, Selise AI, Data Gateway, and project management. Key highlights include a more flexible knowledge base structure, the introduction of reasoning agents, richer note-taking and file interaction capabilities in Selise AI, and improved ownership controls at the project level. Together, these updates improve usability, flexibility, and control across the platform.

AI

Knowledge Base Folders

The Knowledge Base is now available as a dedicated section within the AI module, at the same level as Agents. Previously, knowledge bases were tightly coupled with individual agents and had to be configured within the agent setup.

With this update:

• Knowledge bases can now be organized into folders

• Each folder can be assigned to one or multiple agents

• Agents can consume multiple knowledge base folders simultaneously

• Each folder supports its own:

  • Embedding model

  • Chunking strategy

This separation improves reusability, modularity, and management of knowledge resources across different agents and use cases.

Reasoning Agents

A new Reasoning Agent mode has been introduced for handling complex, multi-step tasks.

Reasoning agents:

• Break down user queries into multiple steps

• Evaluate the output of each step before proceeding

• Iteratively refine responses until a final result is achieved

This mode is ideal for complex workflows, decision-making tasks, and multi-step problem solving, though it may consume more AI credits due to its iterative nature.

Selise AI

Notes

Selise AI now includes a Notes feature within its GPT-style interface, enabling users to create, manage, and interact with structured content directly inside the platform.

Key capabilities include:

• Create and manage notes with Markdown support

• Switch between edit and read modes

• Search across existing notes

• Use undo/redo for editing

• Enhance content using AI-assisted improvements

• Interact with an agent to discuss or refine notes

• Export notes in multiple formats:

  • .txt

  • .md

  • .pdf

This feature transforms Selise AI into a powerful workspace for both content creation and AI-assisted knowledge management.

File Upload

Selise AI now supports file uploads, enabling users to interact with documents directly within the chat interface.

Users can:

• Upload files and reference them in conversations

• Ask questions based on file content

• Use AI to analyze, summarize, or extract information

This brings Selise AI closer to a full-featured, ChatGPT-like experience with enhanced context handling.

Data Gateway

Data Visualization

Data Gateway now provides enhanced data visualization capabilities, allowing users to easily view, filter, and interact with schema data directly within the platform.

Viewing Data

Users can visualize data by navigating to a schema and switching to the Data tab. Data can be viewed in multiple formats:

• Table View — Structured tabular format with per-cell copy support

• JSON View — Raw JSON representation of the data

• Data Details View — Expanded view showing complete record-level information

Each data entry includes quick copy options for improved usability.

Filtering & Sorting

The data view supports flexible filtering and sorting options:

• Filter by Condition

  • Apply one or more conditions

  • Combine conditions using AND / OR logic

• Filter by Column

  • Select specific columns to display

• Sorting

  • Sort data by any field in ascending or descending order

These capabilities allow users to efficiently explore and analyze data without leaving the platform.

Project Settings

Ownership Transfer

Blocks Cloud now supports project ownership transfer, allowing the current owner to assign ownership to another user.

Once ownership is transferred, the new owner gains full administrative control, including the ability to:

• Add or remove users from the project

• Manage user access across environments

• Create and manage environments

• Update the project name

This feature ensures continuity, simplifies team transitions, and improves project governance.

Construct Cli

The Construct CLI has been updated with the following improvements:

• Added environment-based prefixes to VITE_X_BLOCKS_KEY and VITE_PROJECT_SLUG for better configuration management

• Refactored CLI setup instructions for improved clarity

• Removed unnecessary .github folder from generated projects

• Updated the Construct repository reference

To use the latest version:

npm install -g @seliseblocks/cli-os@latest

See the bootstrap guide for full setup instructions. The legacy @seliseblocks/cli package is retired and no longer published.
