January 02, 2024


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

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)

GitHub Issues

In addition, with some overlap, the following issues on github were solved:

  • #4091 A sch wire does not snap to grid for existing wires
  • #4071 Breadboard view misaligned when directly opening a fzpz
  • #4077 Parts Editor crashes clicking on empty schematics
  • #4079 Undo often doesn't work for Bézier curvatures
  • #4035 Voltmeter is reading incorrect value when probe is disconnected
  • #4046 Text lost on Redo
  • #4093 Hover text for parts and connectors not readable in dark mode with Qt 6.5.3
  • #4083 Crash in LockManager
  • #4092 Double-clicking ratsnest lines creates ghost connections

September 06, 2023


This is a maintenance release.
  • Fixed a problem when creating a wire in schematic view (issue #4058)
  • Fixed a regression when entering coordinates (issue #4051)
  • Fixed several bugs that made the IPC export unusable (issue #4050)
  • Fixed broken mouse cursors when non-integer zoom settings are used on Windows (issue #4037)
  • Fixed an issue where undo actions did not remember wire traces width in some cases (issue #4036)
  • Fixed a bug that kept unused duplicate entries in Fritzing files (issue #4023)
  • Added a Warning when user try to order a PCB that has no copper fill
  • Fixed the "Copy and Paste in Place" command
  • Updated some translations
  • Improved support for SVGs with dashed lines, especially in the silk layer of PCB designs
  • Added a new shield example for the Arduino R4 WIFI board

In most manufacturing processes, copper must be etched or otherwise removed. This uses acid and causes waste. To mitigate this, Fritzing will now advise users to incorporate copper fills in their designs before a PCB sent to the Fab.

June 19, 2023


Fritzing 1.0.0 is a major 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 0.9.10

The simulator is now officially supported.

UI improvements
  • Numerous dark mode compatibility fixes: Multimeter, DRC List, Inspector properties, Search line
  • Increased icon size
  • Rearranged Inspector, with flexible previews, supports scrolling
  • Support for pinch gestures, improved scroll wheel vs gesture zoom, use shift for fine control
Part improvements

Added SPICE data for RGB-LEDs and photo cells

New Font OCR-Fritzing

This font replaces the use of OCR-A. It adds Greek letters, diacritics, and other symbols, like á ä å à é ë è ç ṡ, €, Ω, µ, and ß. This way, it supports almost all European alphabets. Support for Cyrillic is planned.

New IPC-D-356 export

Export to IPC-D-356 has been added. This enables third parties to:

  • Verify the PCB correctness during production
  • Render 3D views of Fritzing projects
Gerber export
  • Support for dashed rectangles.
  • Fixed broken fill logic, improved paste layers and outlines.
  • Ignores very small (micro-inch) and zero size drill holes
  • Uses fuzzy compare to avoid rectangles becoming polyline due to rounding errors
  • Stroke-width inheritance now also works without transformation
  • Fixed issue where paths were closed too early or split, causing very distorted rendering of some SVGs.

Optionally, we recommend enabling gerber improvements in the preferences:

  • Fix G54 deprecation
  • Replace deprecated G90 G70 commands
  • Use 6 decimal resolution instead of 3 for gerber export
Pick and place

We have reworked the pick and place file export. We now use the suffix '.xy' for pick and place files. A 'mount' column was added to distinguish between through-hole and surface mount technology. The new format is 'RefDes, Value, Package, X, Y, Rotation, Side, Mount'. The gerbv tool understands this and can render pick and place information, along with drill holes and other PCB layers information.

  • Upgraded to Boost 1.81
  • Upgraded to ngspice-40
  • Upgraded to Qt 6.4.3
  • Upgraded to C++ 17

French, German, Ukrainian, and Russian are now 100% translated again. Nearly complete translations include Bulgarian, Japanese, Portuguese, Vietnamese, Turkish, and Romanian. Many improvements have been made to Spanish.

Fixes and optimizations
  • Avoid rendering slowdown from zooming out
  • Speed up perfboard resize
  • Fixed MacOS "pop-under" effect where new windows are not opened on top
  • Fixed coordinate calculation showing item position in Inspector
  • No longer steals mouse wheel events from Inspector

Continuously updated parts library

The Fritzing parts library is now stored online at github and is automatically checked for updates. This means you will now get new parts (or fixes) in the moment when they are created. No need to wait for the next Fritzing release anymore!

Critical bug fix for messed up PCB traces

We have been plagued by an annoying bug that occasionally caused PCB traces to get loose and flip around. It has been tricky to track down but it's finally fixed, sigh.. Plus, the fix will recover any files that have been mangled by this bug!

High-DPI display support

Fritzing now looks properly on High-DPI (aka Retina) displays on all platforms. It's not really high-res but scaling well according to the higher screen resolution.

Easier handling of self-created parts

Custom / self-made parts and bins used to be stored in a hidden location on your hard drive, which made it really annoying to edit them with an external tool such as Illustrator or a text editor.
They are now conveniently located in your ~/Documents/Fritzing folder for easy access!

Load/Save uncompressed fritzing files (.fz)

You can now alternatively save your fritzing sketches as an uncompressed set of files (.fz plus additional custom parts etc). This allows for proper versioning with systems like git or svn. Thanks to Sergio Oller (zeehio) for this contribution.

File icons

fzz, fzb, fzp, etc. now also have shiny file icons on Mac (thanks to scribblemaniac) and Ubuntu Linux (thanks to el-j - for the latter you have to run the install-fritzing.sh script)

New Parts

Added and/or revised by Fabian Althaus (el-j):
