The Fritzing 1.0.6 release is focused on stability, performance improvements, and the parts library.
We tested it on Windows 11 25H2, Windows 11 24H2 (ARM and Intel), macOS Tahoe, macOS Sequoia, macOS Ventura, Fedora 42, Debian 13.1.0, Manjaro KDE 25.0.9, Mint 22.2 Mate, Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 25.10.
What’s New
Adafruit Parts Bin
We’re excited to introduce a dedicated Adafruit parts bin featuring 83 carefully curated components from our friends at Adafruit. This collection includes many of the most popular maker-friendly parts that the community loves - from sensors and displays to breakout boards and development modules. Having these parts readily available in Fritzing makes it even easier to prototype your next project with components you can actually buy and build with.
Generic IC Improvements
Did you know Fritzing has generic ICs? Many users overlook this powerful feature that lets you create custom integrated circuits for any chip you need. In this release, we’ve made some incremental improvements to make them even more useful:
The generic IC now supports multiline labels and uses our improved font system (Noto Sans + OCR-Fritzing-mono) for better readability. We’ve also standardized the pin spacing to 1 unit in schematic view and improved text wrapping that automatically breaks at spaces and newlines while respecting non-breaking spaces.
The component also respects non-breaking whitespaces (U+00A0 and U+202F) for precise text formatting control.
Work in progress: We’re overhauling the package switching system for this component - more improvements coming soon!
We’ve implemented several behind-the-scenes optimizations that make Fritzing noticeably more responsive. Whether you’re working with complex multi-board projects or browsing through large parts databases, you’ll experience smoother interactions and faster load times throughout the application.

Fritzing 1.0.5 is a maintenance release.
It has been tested on Windows 11 24H2 (ARM and Intel), macOS Sequoia, macOS Ventura, Ubuntu 22.04, and Ubuntu 24.04.
What is new
Windows ARM Support for Windows on ARM CPUs. Fritzing uses Prism on Windows 24H2 to run on ARM.
New Fonts We are fading out Droid Sans and Open Sans in favor of Noto Sans.
This affects mostly the Breadboard and the Schematic View. A bunch of Fritzing parts was using unknown fonts,
which resulted in using whatever fallback font the operating system provided. We have replaced these with either Noto Sans, or OCR-Fritzing-mono.
This results in better i18n support, and fixes several font related bugs.
Sketches will be more consistent when shared between different OSes. We tried to iron out some subtle differences between
OpenType (Linux), Core Text (MacOS) and DirectWrite (Windows) font rendering. Fritzings additional SVG layer made this quite difficult.
Speed We added an option to enable hardware acceleration. Start Fritzing with --opengl to enable it.
The speed gain is notable with some complex sketches, but not huge. In some cases, it will just save battery power,
in others you might see a 20-30% speed improvement.

GitHub Issues
In addition, with some overlap, here is a list of issues that have been
resolved for the 1.0.5 release 
.
The release is available in our downloads section.
Fritzing 1.0.4 is a maintenance release.
It has been tested on Windows 10, Windows 11, macOS Ventura, macOS Monterey, Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 24.04.
What is new
UX: QFN support and working with tiny structures in the PCB was vastly improved. We changed the algorithm that decides which element will receive a mouse click. Ratsnest lines now stay the same size when zooming in. The hitbox size of wires and traces now depends on the wire diameter.
These two images show a PCB at 3000% zoom. The copper traces are 0.2mm (8mil) wide.
Working at this scale was quite annoying in previous versions of Fritzing:
The second image shows Fritzing 1.0.4. We made UI elements scale to proper sizes.
There are quite a number of these changes. More situations where these apply can be seen in issue 3177 on github.
UX: Creating multiple wires of the same size or color is now much easier, as the properties of the recently created wire will also be used for new ones.
Board images: The alpha channel is now taken into account when loading board images. This also fixes many cases where loading an image would result in garbage or blank output.
UX: Show a message when a part must be moved to delete a ratsnest line. Before, we just moved parts without notice.
Bug Fixes
- Fixed crash when using the keyboard for moving parts.
- Fixed ghost connections resulting from moving parts over existing connections.
- Fixed ghost connections when moving a part via the keyboard.
- Fixed error when saving sketch to a write protected destination.
- Fixed repeated read/write operations when saving a sketch, to avoid issues with cloud storage.
- Fixed inactive copper layer after a board was deleted.
- Fixed an error where a move or rotate command was not properly stored, which would result in incorrect undo operations.
- Fixed order of text input fields in Inspector. They were in random order, often changing.
- Fixed input for decimals to work in all locales for text size (Inspector).
New parts
We included the PSoC™ 6 Artificial Intelligence Evaluation Kit (CY8CKIT-062S2-AI), thanks to Janarthanan Nagarajan from Infineon,
and the Calliope Mini 3, thanks to Harald Rau.

Windows 10* or 11 are supported on x86 CPUs.
For Linux, Fritzing requires glibc >= 2.31 and OpenSSL 3 (64-bit Intel/AMD).
The latter OpenSSL requirements typically mean Ubuntu 22.04 or later,
but Fritzing should also run on Ubuntu 20.04.

Fritzing 1.0.3 is a maintenance release.
It has been tested on Windows 10, Windows 11, macOS Ventura, macOS Monterey, Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 24.04. It is designed to work on all Linux variants with glibc >= 2.31 (64-bit Intel/AMD).
Changes since 1.0.2.
Subparts
A number of issues with schematic multiparts have been fixed.
Basic operations like Undo/Redo on multiparts and their subparts were lacking and are now complete.
Subparts can be used to clean up the schematic view. This example shows a 4001 Logic IC.
The gates can be freely arranged to gain a much cleaner and more readable look:
Dark Mode Bugs
Several bugs where Fritzing was not readable in Dark Mode have been fixed.
OS Requirements
The minimum macOS Version is Big Sur.
Windows 10* or 11 are supported on x86 CPUs.
For Linux, we need glibc >= 2.31 and OpenSSL 3. The latter OpenSSL requirements typically mean Ubuntu 22.04 or later,
but Fritzing should also run on Ubuntu 20.04.
*) Very old versions of Windows 10 that have not been updated since 2016 are not supported!
Outlook
If you have a close look, you will see that we started work on a transitory simulator. This feature is not
yet finished. You can try it by starting Fritzing in debug mode (-d option). It may not work at all, or even
crash, though. There is still a lot missing.

.

Fritzing 1.0.2 is a feature release. It has been tested on Windows 10, Windows 11, macOS Ventura, macOS Monterey, Ubuntu 20.04, and Ubuntu 22.04. It is designed to work on all Linux variants with glibc >= 2.31 (64 bit Intel/AMD).
Changes since 1.0.1.
Copper fill
The Copper Fill algorithm is now vector based. This fixes a number of bugs along, especially with Ground Fills, most prominent the annoying horizontal gaps in the copper fill. It results in higher precision, and more predictable behavior. It also enables a number of Gerber improvements and new features for PCBs in the future. The old rasterized copper fill algorithm was kept available, so you may compare the two against each other.
Fab upload
Refactored fab upload. We can now send properties like width and height along with Gerber, IPC and BOM. At the same time this will shorten the development cycle when adding new features or fixing bugs.
Data structure fixes
We’ve upgraded Fritzing’s data management, fixing several issues that led to discrepancies between views, missed errors in Design Rule Checks, and invisible, uneditable ‘ghost’ connections in the netlist. To rectify these in existing sketches, a simple delete-and-undo action on the problematic elements will clear the bugs. These improvements, which affect numerous example projects, should result in more reliable and understandable behavior from Fritzing going forward.
Testing infrastructure
We’ve significantly enhanced automated testing, allowing us to conduct hundreds of Fritzing sessions every minute.
Moved to Qt 6.5.3.
Just the due maintenance.
OS Requirements
Minimum macOS Version is now Big Sur, before it was Catalina. Windows and Linux requirements didn’t change, but Linux now must use OpenSSL 3, support for OpenSSL 1.2 was dropped)
