1.0.4

Changelog for Version 1.0.4

New Features and Enhancements

• 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.
• 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.
• PCB Outlines: 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).

We thank our community for their invaluable feedback and contributions. Your support helps us improve with each release.

1.0.2

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

1.0.1

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.
