Raylux 2026.21 is a big one. Every product has a new, brighter look; Iris, the built-in assistant, is complete; and the designer gains a node editor for scripts, a much better binding editor and a long list of new screen components.

Raylux 2026.20 introduces Raylux Iris, which lets the AI assistant you already use look at your plant and help you understand what is going on.

Raylux 2026.19 is the first release since 2026.12.

Raylux now numbers its releases by year: this is 2026.12, the release after 1.0.10.

Read the full Raylux 2026.12 release notes: Versions and licensing, Projects and Screens

This release lets one project share its screens, popups and styles with others, makes reusable screen pieces work fully when placed inside other screens, enforces limits on numeric entry fields, and fixes a tag import that could leave every live value bad until the gateway restarted.

This release fixes operator screens that stopped showing some of their values once a page carried a large number of live tags, and makes a newly uploaded image appear on open screens without reloading the browser. We recommend it for every gateway serving busy screens.

Read the full Raylux 1.0.9 release notes: Screens

This release fixes how the gateway reports a PLC it cannot read, speeds up Allen-Bradley communication, and adds new screen components: vector drawings, images, a moving analog indicator and a project stylesheet.

The gateway now installs on Linux from a package, on both Debian/Ubuntu and Fedora/RHEL. Nothing changes on Windows; this release carries the new version number so all downloads match. New: an .rpm for Fedora and RHEL.

Licensing changes. If you are running 1.0.0, replace it with this — the 1.0.0 download was built before these changes and does not include them. Unlicensed gateways now stop.

Raylux leaves pre-release. The gateway, the designer, the web runtime and the plant-floor client ship as one versioned product for the first time.

A batch of fixes found while building and running a real fan-control HMI on a live plant. Discrete alarm modes — equal, not-equal and bit-state — alongside the existing limits. Per-limit delays before an alarm becomes active or clears, so a brief excursion does not raise one.

Everything here came out of building a real fan-control HMI on Raylux, and each item was fixed in the product rather than worked around in the screen.

Studio picks up a licence change without being restarted. Studio built its workspace list once at start, so activating a licence or restarting the trial did not show or hide the affected workspaces until Studio was relaunched.

Closes the gap 0.31.1 shipped with. 0.31.1 moved six credential fields into the protected store but left one known gap: a device password edited through the gateway interface was still written in clear text.

Read the full Raylux 0.31.2 release notes: device passwords join the credential store

Six credential fields no longer sit in clear text in the gateway's configuration. Mail passwords, messaging tokens, single-sign-on secrets, database passwords and device passwords now live in a separate, owner-only file, with the configuration holding only a reference.

A large release: four new protocol drivers, OPC UA server support, electronic signatures, and the Edge product tier. DNP3 (with sequence-of-events timestamps and unsolicited data), BACnet/IP, Siemens S7 over ISO-on-TCP, and Omron FINS over TCP and UDP.

Performance work on the gateway, and fixes in the designer and the plant-floor client. The gateway's write path is about 44% faster — 66,900 to 96,200 values per second, measured.

Read the full Raylux 0.30.3 release notes: a faster write path

A fix batch across the designer, the plant-floor client and the gateway. The designer stops drifting from the runtime.

Restoring a gateway configuration is a file upload now, and backups download as a recognisable file. Restore used to be a paste box.

Two new capabilities: a new PLC family, and Linux, including the Raspberry Pi. CLICK PLUS speaks Modbus TCP, so it never needed a protocol driver of its own. What it needed was a translation from the names an engineer actually authors in the CLICK software onto Modbus addresses.

Scripts are written in a real editor now, and every small code box in the product grew up. A Workspaces screen in the gateway interface, so "why is this module missing from Studio" has an answer you can read.

The installer asks which capabilities a gateway should offer, and the gateway honours the answer. A Gateway workspaces page in setup offers the HMI runtime, alarm pipelines, reporting, named queries and notifications. Clearing one stops the gateway offering it.

Long trends stop dragging their whole history across the network, plus a batch of driver and interface fixes. Wide trend windows are now summarised inside the database, so a long trend never leaves it as raw rows.

Read the full Raylux 0.27.0 release notes: historian trend aggregation

Indirect bindings, with write-back, end to end. A binding can now build its tag path from other values on the screen rather than naming one fixed tag, so a single faceplate can serve every pump on a line by being told which one it is looking at.

Client licence metering, the groundwork for alarm notification, and the licence format settled for good.

Read the full Raylux 0.25.0 release notes: client licence metering and the alarm notification core

An installer and licensing release. Nothing in the runtime changed except the Downloads page fix. A gateway is usually a server, and it should not acquire a designer and an HMI runtime nobody asked for. The installer now sets up the gateway and leaves the clients alone.

Documentation ships for the first time, and three faults live on every gateway are fixed. A 19-page manual installs with the gateway and is served at /manual, with no internet required.
