Flux April 2026 release: upgrades that make a real difference

If you’ve been using Flux week to week, you’ve probably noticed a steady drumbeat of small changes. This release is a snapshot of what we shipped across January to March, the concrete stuff that makes designing in Flux faster, more reliable, and a little less fiddly.

Core EDA improvements

Accuracy: calibrate screen size (true 1:1 scale)

You can now calibrate your screen so components and projects appear at real-world physical scale.

Why it matters: when you’re working in tight mechanical constraints (enclosures, board outlines, connector placement), “close enough” on-screen scale is still friction. Getting to true 1:1 helps you make better placement decisions faster.

Editor speed: faster editing + undo/redo

We made the editor more responsive and improved undo/redo performance.

Why it matters: when you’re iterating quickly, latency breaks flow. This is the kind of improvement you feel constantly, even if it’s hard to point to one “feature.”

PCB Layout workflow: Layout Rules panel in the Inspector

We added a dedicated Layout Rules panel in the Inspector.

Why it matters: rules and constraints are easier to discover and adjust when they’re surfaced where you’re already working. This shortens the loop between “what’s going wrong?” and “fix it.”

Pads/Silk etc. can now be placed directly from the PCB editor canvas

Why it matters: It enables a faster and more natural workflow, simply place vias, pads, and silkscreen features right from the context menu accessible by right clicking on the PCB canvas.

Interoperability: importing existing designs

Import Eagle into editable schematics

You can import Eagle schematic files (.sch) into Flux and keep them editable.

Why it matters: migration is only useful if you can keep working once you land. This makes Flux a more practical option for teams with real legacy designs.

Import PADS ASCII footprints

Flux now supports importing PADS ASCII footprints.

Why it matters: footprints are often the blocker when moving between tools. Every new import path reduces busywork and makes it easier to reuse what you already trust.

AI improvements

AI Agent: more reliable, longer conversations

We improved Flux Chat’s ability to stay stable and usable in longer threads.

Why it matters: when an assistant loses context (or becomes slow) mid-task, it’s not just annoying — it breaks the workflow. The goal here is: you should be able to keep going without “resetting” the conversation.

Simulator: chats stay responsive on long threads

We made simulator chats stay responsive as threads get longer.

Why it matters: simulation is iterative. You shouldn’t have to restart the loop just because you’ve been working for a while.

AI Agent: better “hands-off” finishing

AI Agent now does more cleanup work automatically before it finishes.

Why it matters: the best automation removes the boring steps without you having to babysit it. This is one of those changes that turns “AI could help here” into “AI did help here.”

Part Creation Improvements

Place pins on top and bottom of parametric symbols

Flux now supports the placement of pins on top and bottom of parametric pins by specifying the Pin Orientation property.

Why it matters: This allows users to create clean and readable symbols.

Pad numbers now auto increment when placing Terminals

Why it matters: Pad numbers don’t have to manually entered for each Terminal anymore speeding up the workflow greatly.

Key component properties are now auto-added

Why it matters: Certain properties are required for a high-quality BOM. We now automatically add Manufacturer Part Number, Manufacturer Name, Part Type, Datasheet URL, and Designator Prefix to ensure a strong baseline across symbols.

What’s next

Flux is moving fast. The goal isn’t change for change’s sake — it’s to keep tightening the loop: faster iteration, fewer workflow breaks, and better support for the formats and tools you already use.

If there’s a part of your day-to-day flow that still feels slower than it should (or a paper cut you hit every session), tell us. Those are often the highest-leverage fixes, and they’re exactly what we’re prioritizing.
