The RC removes the initialize handshake and sessions: state is passed via explicit handles, follow-ups go through InputRequiredResult without SSE. Load balancing over plain HTTP without sticky sessions.

The RC introduces Extensions (reverse-DNS IDs, capabilities, versioning): MCP Apps serves HTML in a sandbox iframe, Tasks offloads long-running operations. A narrow core, growth through modules.

The RC carries W3C Trace Context in _meta for end-to-end trace correlation and introduces a lifecycle policy: at least 12 months between deprecation and removal.

2.4.9 added Symfony 7.4 LTS and PHP 8.5, extended CAPTCHA to REST/GraphQL (closing the API bypass). 581 core improvements; the clearCart mutation is now open to Open Source.

An MCP server was announced at Adobe Summit 2026: AI agents gain access to the catalog, cart, prices, stock and checkout. It depends on the Integration Starter Kit and AppBuilder.

The AI suite analyzes the implementation, builds a migration path to ACCS, and rewrites legacy code into event-driven components. Status is coming soon; it is not publicly available yet.

Studio (React/TypeScript) becomes the only interface, all ExtJS is removed, bundle versions are unified. The 2026.x branch requires Symfony 7.4.

AI agents read and propose changes to objects and assets through MCP under the same permissions and workflows as people. All actions go through the Data Spine layer.

deliveryOptionsCalculate replaces implicit shipping webhooks. Search has been redesigned (prefixes, operators, ranking); gift cards are paid via the Transaction API.

The roadmap sets 4 priorities (transport, agents, governance, enterprise) and a shift from a release-centric plan to Working Groups. Enterprise via extensions, not the core.

Saleor released Paper — a production-ready storefront with a mobile multi-step checkout. It includes an AGENTS.md with rules for AI tools (Cursor, Claude, Copilot).

Adobe announced support for the open UCP (Google) and ACP (OpenAI/Stripe) protocols, in addition to Agent Payments Protocol, so products can be purchased through ChatGPT and Gemini.

Share groups declared production-ready: consumers read the same partitions with per-record acknowledgment — a classic queue on top of Kafka.

Kafka Streams group management has been moved to the broker side: task assignment, topology storage, and observability are now generally available.

Kafka Streams exception handlers gained built-in routing of failed records to a dedicated queue (DLQ) instead of manual wiring.

Akeneo released a native MCP server: the catalog as resources, agent edits as tool calls, and server-side quality rules. The release also includes Digital Showroom and Custom Components

In its Winter Release, Akeneo announced a partnership with the Stripe Agentic Commerce Suite: product discovery by AI agents and acceptance of agent payments. The release's MCP server is covered separately

The last release with Admin UI Classic alongside Studio. An experimental MCP server reads data over Elasticsearch/OpenSearch. Symfony 7 alongside 6.4, with 3-year LTS.

Instead of the problematic DCR (SEP-991) — Client ID Metadata Documents (client_id as a URL pointing to JSON). Cross App Access (SEP-990) shifts authorization to the organization's IdP.

Saleor shipped an official Adyen integration for international payment acceptance and refunds. It is implemented through the App model rather than a built-in core plugin.

An MCP server launched, giving LLMs access to store data (channels, orders, products, stock) over Streamable HTTP. Read-only, no mutations; Saleor 3.21+ and Saleor Cloud.

The app connects a Saleor store to ChatGPT via OpenAI ACP, exporting the catalog to an ACP feed. For now the feed is exported manually; payment and checkout in ChatGPT are the next stage.

GenAI in Akeneo fills numeric and Yes/No attributes, extracts specifications from PDFs with unit conversion, and pulls values from reference entities. AI Configuration has been added

The rules engine gained triggered rules — real-time execution on product updates, tied to workflows. Akeneo DAM was re-released with AI asset tagging

Copilot generates text through Chat Completions, so it connects to different LLM providers (OpenAI, Hugging Face, RunPod). Documents appears in Studio for the first time (preview).

A public catalog and API of MCP servers opened at registry.modelcontextprotocol.io (Anthropic, GitHub, PulseMCP, Microsoft). Preview, with no data guarantees and breaking changes until GA.

Release 4.1.0 brought share groups to preview (not for production) and added early access to the Kafka Streams rebalancing protocol (KIP-1071).

Akeneo introduced its first AI agent, Data Architect Agent: based on sample product files and context, it drafts a data model. GA for Product Cloud is July 12, 2025

PX Insights shows how AI assistants like ChatGPT interpret and recommend products. In Spring 2026 — a closed loop that suggests missing words and attributes

Over 30 Symfony components now run in version 7 alongside 6, paving the way for migration. Asset metadata select fields pull values from external sources; the Datahub File Exporter writes to the directory tree.

The multi-tenant SaaS edition of Adobe Commerce became generally available (Americas from June 25, 2025, then EMEA and JPAC). Versionless with automatic Adobe updates instead of self-hosted/PaaS.

3.21 added the first OpenTelemetry stream (traces and metrics) for APM tools (Datadog, Grafana, Uptrace). It covers Saleor Core, apps and services.

2.4.8 fixed ~497 core bugs, added PHP 8.4, MySQL 8.4 and MariaDB 11.4 LTS, extended GraphQL for headless and B2B (negotiable quotes), and strengthened 2FA with Duo Security.

The first major release entirely without ZooKeeper: metadata is managed by default by the built-in Raft (KRaft), reducing operational complexity.
