Matter Versions Explained: What Each Release Added, From 1.0 to 1.6

The short answer

Matter is published by the Connectivity Standards Alliance (CSA) as numbered releases. As of October 1, 2026, the latest is Matter 1.6, released on June 17, 2026. The CSA has not announced a "Matter 2.0".

Several features that have been described as coming in a "Matter 2.0" already arrived in 1.x releases: robot vacuums in Matter 1.2 (2023), EV chargers and energy reporting in Matter 1.3 (2024), solar, home batteries, heat pumps and water heaters in Matter 1.4 (2024), and cameras in Matter 1.5 (2025).

A new release is the start of the process, not the end. Device makers have to build and certify products against it, and Apple Home, Google Home, Amazon Alexa, SmartThings and other platforms add support for new device types on their own schedules. "Matter 1.5 supports cameras" does not mean every Matter app shows every Matter camera yet.

Correction

An earlier MatterCatalog article, "Matter 2.0: Everything You Need to Know" (February 2026), said cameras, robot vacuums and energy management devices were new in an upcoming "Matter 2.0" expected in mid-2026. That was wrong. No Matter 2.0 had been announced, and those device types arrived in the 1.x releases below. Our earlier Matter 1.3 overview also listed water heaters and refrigerators as new in 1.3; they arrived in 1.4 and 1.2. We retired both articles, and their addresses now lead to this page.

Every Matter release at a glance

What each release added

Matter 1.0 (October 2022)

The first release covered the most common smart home devices: lighting, plugs and switches, door locks, thermostats and HVAC controllers, blinds and shades, security sensors such as door, window and motion sensors, TVs and streaming players, and bridges that bring other devices into Matter. Matter runs over Wi-Fi, Thread and Ethernet, and most devices use Bluetooth Low Energy during setup. The standard grew out of Project CHIP ("Connected Home over IP"), which the CSA renamed Matter in May 2021. Sources: CSA: Matter arrives and CSA: Project CHIP is now Matter.

Matter 1.1 (May 2023)

A maintenance release with no new device types. Its main change improved support for intermittently connected devices: the battery-powered sensors, locks and switches that sleep most of the time. They can sleep longer and are less likely to show as offline. Source: CSA: Matter 1.1.

Matter 1.2 (October 2023)

Added nine device types: refrigerators, room air conditioners, dishwashers, laundry washers, robotic vacuums, smoke and carbon monoxide alarms, air quality sensors, air purifiers and fans. The robot vacuum type covers starting a clean, cleaning modes such as vacuuming or mopping, and status details such as charging and errors. Source: CSA: Matter 1.2.

Matter 1.3 (May 2024)

Let any device type report energy: instantaneous power, voltage and current, and the energy used or generated over time. It added EV charging equipment, with start and stop, charging rate and a target range by a departure time; water management devices (valves, leak and freeze detectors, rain sensors); and microwave ovens, ovens, cooktops, extractor hoods and laundry dryers. Scenes also became part of the specification. Source: CSA: Matter 1.3.

Matter 1.4 (November 2024)

Focused on home energy: solar inverters and panel arrays, home batteries, heat pumps and electric water heaters, and device energy management, which lets an appliance shift when it runs based on forecasts. EV chargers gained charging preferences, and thermostats gained schedules and presets. The release also added certified home routers and access points that can include a Thread border router and share Thread credentials, Enhanced Multi-Admin to make adding one device to several ecosystems simpler, and a Long Idle Time mode for longer sensor battery life.

Matter 1.4.1 and 1.4.2 (2025)

Matter 1.4.1 (May 2025) targeted setup: one QR code for a multipack, setup details stored in an NFC tag for products whose QR code is hard to reach once installed, and an Enhanced Setup Flow that shows a maker's terms inside the platform's own app. Matter 1.4.2 (August 2025) added setup over Wi-Fi alone for products without Bluetooth, security features such as certificate revocation, certifiable scenes, standard robot vacuum behaviors, and a requirement that certified Thread border routers support at least 150 devices. Sources: CSA: Matter 1.4.1 and CSA: Matter 1.4.2.

Matter 1.5 (November 2025)

Added cameras, with live video and two-way audio streamed over WebRTC for local and remote viewing; a redesigned closures model that covers shades, drapes, awnings, gates and garage doors; soil sensors; and energy tariff information, so devices can exchange electricity prices and grid carbon intensity. Source: CSA: Matter 1.5.

Matter 1.5.1 (March 2026)

A camera-focused update: several video streams from one camera at once, HEIC snapshots, better pan-tilt-zoom handling, and fixes for doorbells, chimes and intercoms. Source: CSA: Matter 1.5.1.

Matter 1.6 (June 2026)

Added no new device categories. Setup can now run entirely over NFC, so a bulb or in-wall switch can be added before it is installed. Joint Fabric lets several controllers that you authorize share one Matter network instead of each keeping its own. Platforms can send a thermostat time-limited suggestions instead of direct commands, security sensors can report event history, and smoke and CO alarms can report when they have been taken down from where they were installed.

What a new release means for what you buy

Three things have to line up before a feature works in your home:

1. The device. The maker has to build the feature and certify the product. A device certified under an older release gains new features only if the maker ships a firmware update for them.
2. Your platform. Each platform supports its own subset of device types. Amazon, for example, says its Matter-compatible Echo devices use the Matter 1.5 SDK and support "a subset of Matter 1.5 and lower device types" (Amazon developer documentation). Apple, Google and Samsung publish their own lists.
3. Your network. Matter devices that use Thread also need a Thread border router; see Thread border routers explained.

Before you buy, check the exact model on the maker's page and in the CSA certified product database, and check that your platform lists the device type. MatterCatalog product pages show a CSA certificate when we have matched one to the exact record.
