Maintenance release

This is a maintenance release. There are few new features, but we fixed some of the bugs.

Critical bug fix for autorouter

Fixed a memory corruption that would random crashes. Thanks to Filipp Mikoian for your help.

Color coded wires
An new option was added to automatically colorize wires according to their length.
Transport Layer Security

Long overdue, Fritzing now uses TLS for all links. The Fritzing website continues to allow http access to support older Fritzing versions.

Fix a bug where Fritzing would potentially search the whole disk for parts

Depending on installation location, Fritzing might try to search many subfolders for its parts. Depending on the machine's speed and directory structure, this would take a long time, during which Fritzing would show "Application does not respond" or similar. The workaround was to wait about ten minutes until it finishes, as it only happens on the first start. This annoyed many users, our apologies, this behavior should be fixed now.

No 32 bit builds
We don't provide 32 bit builds of Fritzing anymore. It might still be possible to build for 32 bit.
Under the hood

We dropped Qt4 suport

Continuous builds for Linux, MacOS and Windows. This means faster release cycles in the future.

Use libgit 0.28.1

New/updated Translations
  • Russian thanks to Alexey Loginov
  • Indonesian, thanks to Rizqy H
  • Slovak, thanks to jose1711
  • Slovenian, thanks to Filip Stamcar
  • German
  • French
  • Bulgarian, thanks to Lyubomir Vasilev

Also, many more improvements and fixes, including contributions from Chris Mayo, Peter Van Epp, Ben Williams, Michael Anderson, Roman Vekshin. Thanks to the guys at Aisler.net, without whom this release would not have been possible.

June 02, 2016


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):
