I’m happy to announce LibrePCB 1.1.0 which was released today! Once again there are some exciting new features, check out the details below.


Live Parts Information (#1313)

Who didn’t already finish a PCB project and then — while ordering the parts — realized that several parts in the schematic are obsolete, not in stock or unexpectedly expensive? This is annoying and wastes time for evaluating new parts and adjusting the PCB layout again.

Luckily with LibrePCB 1.1.0 you now see much earlier in the design phase which parts are good to use! When adding new parts to a schematic, you’ll immediately see their lifecycle status, availability, price and more:

In addition, the BOM export dialog gives you an overview about the status of all parts used in the project and even shows you their total price:

Since such information can change quickly, it is not stored in our libraries but requested through our online API on demand. The actual data about parts is kindly sponsored by Partstack — without their support, it would not be possible for us to provide this feature.

In case you worry about this new internet-based feature: We take privacy very seriously and absolutely no personal data (e.g. IP address) will be forwarded to any third-party (not even to Partstack). Also it is possible to disable this feature. See details here.

EAGLE Project Import (#1318)

Still using EAGLE and looking for alternatives now since it has been abandoned? Or already using LibrePCB, but still having many old EAGLE projects?

No problem — in addition to the already existing EAGLE library import, you can now even import whole EAGLE projects, allowing you to smoothly migrate from EAGLE to LibrePCB! Well, at least within some limitations since such importers by design can’t be lossless 😉 However, we think it works very well for many EAGLE projects so you should definitively give it a try.

For more details about its limitations, check out this pull request. If you encounter a problem not mentioned there, please let us know!

Interactive Device Pinout Assignment (#1309)

The most important step of creating a new device is to define its pinout, which can be quite cumbersome and error-prone, especially for devices with many pads. This changes with LibrePCB 1.1.0:

Any pads whose name match with a component signal (e.g. a connector with pads 1..20) can now be assigned with just a single click.

And for any remaining pads, an interactive mode helps you to do the assignment pad by pad. A filtering feature and extensive keyboard shortcuts make this mode very efficient.

Improved Support for Dark Themes

This is actually just a small change, but thanks to theme-aware toolbar icons and improved colors, LibrePCB is now much better usable (and looks better) on systems with a dark theme.

Qt6, 64-bit Windows Releases, Offline Installer

Normally I don’t consider internal technical changes as a highlight, but this time a technical change has notable impact especially for Windows users. Starting with LibrePCB 1.1.0, we now support Qt6, the successor of the C++ toolkit Qt5 which LibrePCB is based on since its very beginning. Together with Qt6 we now provide 64-bit releases for Windows.

In addition, this new 64-bit release is now built with a new installer toolkit. Instead of downloading LibrePCB from the internet during the installation, this is now an offline installer not requiring internet anymore. Due to the different CPU architecture, the new installer defaults to the location C:\Program Files\LibrePCB instead of C:\Program Files (x86)\LibrePCB. During installation it will ask you to uninstall any previous LibrePCB version.

Note that these Qt6/64-bit builds are currently considered beta. For productive use we recommend the still available Qt5 (32-bit on Windows) builds for now, as promoted on the download page. For upcoming releases we plan to drop these Qt5 builds so only the Qt6 builds will be available then.

The move to Qt6 forced us to drop support for Windows 7, Windows 8 and any 32-bit versions — upcoming releases will require at least Windows 10 64-bit. Since Windows 7 and 8 are already end-of-life for quite some time, it is highly recommended anyway to not use these systems anymore. But for now you can still use the Qt5 builds on them.

I’m happy to announce that once again there will be a LibrePCB talk at the next FOSDEM, which takes place in February 2024!

After the Open Hardware devroom did not exist at the last FOSDEM in 2023, luckily this devroom will be back at FOSDEM 2024 where I’ll give a status update about the LibrePCB project. So if you’re curious about the progress of LibrePCB (also behind the scenes), feel free to join the conference — either in person or via live stream.

I’m looking forward to meet you at FOSDEM 24!

September 24, 2023

After a few weeks of testing the RC1 and bugfixing, finally the stable release of LibrePCB 1.0 is finished and available for download! Check out the awesome new features and the migration notes below.

For the reasoning behind bumping the version number to 1.0, check out the blog post LibrePCB 1.0 Roadmap.


Advanced PCB Features

One of the goals of this release was to get rid of several limitations which made LibrePCB 0.1.x unsuitable for many PCB projects. Therefore the following board editor features are now available:

  • Thermal relief pads in planes (#1160)

  • Blind & buried vias (#1163)

  • Plated and non-plated slots (#1071, #1076)

  • Keepout zones (#1167)

  • Rounded and custom footprint pad shapes (#1102, #1103)

  • Configurable automatic stop mask and solder paste on pads (#1137)

  • Fiducials and other pad types (#1142, #1143)

So there should be no show stopper anymore which prevents you from using LibrePCB for more complex PCB designs! 💪

3D Viewer & STEP Export (#1156)

Finally it’s possible to review the PCB design in a realistic 3D viewer, with proper rendering of copper layers, solder resist and silkscreen! Even devices are rendered if STEP models have been assigned to their packages in the library. In addition, the whole PCB can be exported as a STEP model so it can be opened in a mechanical CAD.

For a detailed description, check out the corresponding pull request — or just watch this nice GIF! 😀

Since your existing projects do not contain any 3D models yet, initially only the plain PCB will be rendered without any devices on it. To get the devices appearing, you need to add 3D models to the corresponding packages in your libraries. Afterwards you need to trigger Project 〉Update Project Library to update the packages in your project.

Our official libraries already contain some 3D models, but there are still many packages without 3D model. Just look for library updates from time to time.

MPN Management & Assembly Variants (#1180)

It is now also possible to specify manufacturer part numbers (MPNs) in the library so that you don’t need to manually enter them every time you add a component to a schematic. These MPNs will then be exported to the BOM to get very accurate information about the parts you need to order.

But adding just one MPN is sometimes not enough. Probably most hardware engineers experienced supply chain issues in the last few years and learned how important it is to define second source parts. With LibrePCB you can now even explicitly specify alternative parts in the schematic which will get exported to the BOM too!

In addition, it is now possible to define multiple assembly variants of a project, for example to omit ("do not mount") specific parts in some of the product variants. For more details about this feature, please take a look at its full explanation.

Unified Production Data Files Generator (#1194)

With LibrePCB 1.0 you can now export production data like a pro! Thanks to so-called output jobs, this task has become very easy, fast, flexible and reproducible:

With the archiving job, there’s even no need anymore to manually create a ZIP file for sending Gerber files to your PCB manufacturer. Just specify the ZIP filename and which job outputs shall be contained, and LibrePCB creates the ZIP in a few milliseconds for you.

These jobs can not only be executed from the graphical interface, but also from the command-line. So if you like to automate the generation of output files (e.g. on a continuous integration system), now you can!

Migration Notes

Workspace & Libraries

When you open your existing workspace the first time with LibrePCB 1.x, it needs to be upgraded to the new file format. A wizard will automatically guide you through this (very simple) process. Generally it just recursively copies the workspace directory v0.1 to a new directory named data.

If you’re working with external tools (e.g. Git) on libraries, keep in mind to access them with the new path instead of the old one.

After the workspace migration it can take several minutes until your libraries are accessible because they are migrated to the new file format in background.


Once you open a LibrePCB 0.1.x project the first time with LibrePCB 1.x, it will automatically be upgraded to the new file format. After saving it to disk, it won’t be possible anymore to open it with LibrePCB 0.1.x.

Note that although the upgrade is generally not critical, there might be small differences in your board after the upgrade. LibrePCB will show you a list of what has changed during the upgrade.

Installation / Packaging

From this release on, we do no longer provide an installer for Linux and MacOS. If you installed LibrePCB 0.1.x with the installer, we recommend to uninstall it and then install it with a different method.

For package maintainers: Note that LibrePCB now depends on Qt Quick, OpenCascade, OpenGL and GLU (at build time and runtime). See details here.
